Toshiba Satellite 1905. How to remove and replace notebook memory.
Today I had to replace the memory module in Toshiba Satellite 1905 notebook. This notebook has 2 memory slots. One memory slot is located on the bottom of the notebook and you can access it pretty easy. The second slot is located under the keyboard and you have to remove the notebook keyboard before you can remove, replace or upgrade the memory module. By default the memory stick is installed under the keyboard. Be very careful with the keyboard securing strip, it is very fragile and seated in place very tightly.
What memory should I use for upgrading my notebook computer? How to choose the right memory type and size?

I need repair fan cooler, in my toshiba 1905 s301, before its steps, how I must proceed?

Hi there,
To replace the CPU cooling fan in this model, you have to completely take apart your laptop and remove the system board. After you remove the system board you can get an access to the fan. I haven’t created a disassembly guide for this model yet, so cannot give you step-by-step instructions. Just go through some disassembly guides and you’ll get an idea how to remove the system board. You still have to pass all steps described in the above mentioned guide in order to open the laptop case.

Hello. I need to replace the keyboard on my 1905-S301 because the H key popped off and will not work very well any more. I saw that you said something about a keyboard securing strip. What is this and is it difficult to put a new one in after I take the old one out???
P.S. I’m know nothing about modding computers and don’t want to screw this up. Please help.
Thank you.

Hi Conor,
It is pretty easy to replace the keyboard on Toshiba Satellite 1905. You can see how to remove the keyboard strip on the step 3. The keyboard securing strip is a peace of plastic that located on the top of the keyboard and covers the keyboard securing screws. You can remove the strip with a sharp object, for example a flat head screwdriver. After you replace the keyboard you just place the strip back in place and snap it in. To replace the keyboard you have to follows steps 3,4,5. Do not forget to remove the battery and be very careful with the keyboard connector on the system board; unlock the connector before you pull the keyboard cable from it.

I need more help with disassembly, I took apart all the sections on the bottom and the keyboard is out, but I’m stuck; it’s a Satellite 1900 but judging from these pictures the case is identical. Any ideas on how to get that metal plate out, or if that isn’t necessary, how to get to the CPU, because it’s overheating quickly and I want to clean it thoroughly now!
April 23rd, 2006 at 10:20 pm
Hi Rygir,
The metal plate under the keyboard is a part of the top cover assembly. To get access to the cooling fan you have to remove the top cover. I do not have a guide for removing the top cover assembly for this model, but I can give you some instructions:
1. Remove all screws on the bottom of the laptop. Do not forget 5 screws in the battery bay and 3 screws in the CD-ROM drive bay. You have to remove the CD-ROM first. Also remove all part displayed in my guide.
2. Remove 3 screws on the side where the VGA and parallel connector are located.
3. Remove the plastic piece located between speakers and covering the display cable connector.
4. Remove speaker covers. You have to remove 2 screws before.
5. Remove 7 screws on the metal plate and 2 screws located close to the speakers.
6. Using a guitar pick release plastic latches and lift up the top cover assembly.
You can read through other disassembly guides to get a better idea. Good luck!

I can’t find how to release the CD/DVD rom, I think it has something to do with the metal when you open the center plate on the bottom of the laptop (where you can place cards, which I don’t have). And if I get it out, are those screws located ± where those extra screws are located in the disk drive bay (about where the plastic front of the drives is)?
Another problem I had was that I couldn’t get into the section for the CPU, because I didn’t have star screwdrivers that small. I filed down a tiny inbus and unlocked that cover, then removed the tiny clamps holding down the soft metal plate that keeps the cooling block, and lifted the cooling block out. To my surprise, the entire CPU came along. the side where the air is blown into the block was completely clogged, a 2mm thick layer of black dust. I took that off, vacuumed the entire thing, and although there were some particles left between the copper plates I decided to put it back together, because they wouldn’t come out and it was very little. I tried vacuuming the section with the fan from here, but it didn’t work well, the fan is still dirty. Now I’m a bit scared, because I’m trying to put it back together, so I screwed on clamp fairly tight, and then the other…but when I did that it sounded like…when you push your finger into foam, a soft crackling sound. It went fairly smooth, but the noise worried me, and because it was a fairly steep angle, I really hope I didn’t bend any pins. When I had screwed both sides down I could still give it another push and it sank even deeper all of a sudden… either it fits perfectly now, or my CPU’s pins are all destroyed…
I’m looking through my camera videos right now, to check where a small metal piece has to go, I can’t remember.
If I manage to get it back together, are you interested in the videos? It’s not incredibly detailed, but when edited it might be useful for someone.
If you ever make a guide, I suggest making a couple overview shots and marking all the screws on them, possible using a colour code (because there are only about 3 different types, that should be fairly easy).
Last problem : I couldn’t find those plastic latches, I was going to use a knife, but because I didn’t know where to find them, I couldn’t release them (also, I don’t have a guitar pick). However I don’t think I’m going to risk further dissassembly because it took me the better part of an hour to reconstruct a damaged plug (for on of the speakers, the soft plastic broke when I disconnected it, and now I had shove the cables in, which I managed and I don’t feel like doing it again
…
April 29th, 2006 at 8:59 am
Well…I now have a tiny metal plate and I can’t figure out where it’s supposed to go;
If you make a guide, an “end result” overview with all the pieces and where they came from will help people that attempt to do this a lot! Perhaps even total counts of screws, per section, so they can be sure they didn’t miss one.
Anyway, you wouldn’t happen to remember where a small rectangular metal plate, 7mm wide, 4cm on one side, 3cm on the other (it has a small flap)has to go? It has a screwing hole on one side.
Attempt to sketch :

Rygir,
To remove the DVD drive you have to remove one screw located in the memory bay. Remove the memory cover and you will see the screw. After the screw is removed you can slide out the drive. When the drive is removed you will see 3 screws that you can easily access.
When you remove the heatsink it is very possible that the CPU would be attached to the heatsink. You have to be very careful with the CPU pins! If the CPU came out with the heatsink, you have to separate it from the heatsink before you put it back in the socket. To separate the CPU from the heatsink I usually use a flathead screwdriver. I place it between the CPU and the heatsink and rotate just enough to lift up the processor. Before you put the CPU back in the socket you have to UNLOCK THE SOCKET. There is a screw on the side of the CPU socket and it could be either LOCKED or OPEN. So, you open the lock, put the CPU back in place and lock the screw. Do not push on the CPU when you put it back, it should fit into the socket pretty easy. The CPU and the socked are keyed, make sure to match the key. If you forget to lock the socket screw your laptop will not start when you assemble everything back.
You also have to clean up old thermal grease from the CPU and the heatsink and put new thermal grease on the CPU before you install the heatsink back in place.
About plastic latches on the top cover assembly. You will not see them until you lift up the top cover. Sometimes you do need to use a guitar pick, you just lift up the top cover.
I am not sure where the metal plate is coming from, cannot memorize.
April 29th, 2006 at 1:01 pm
I’ve got it all back together, except one problem which I will get to in a minute.
The DVD drive : I just had to pull harder to get it out
.
I DID NOT seperate the heat sink and CPU (mainly because I think it’s attached using a thermal adhesive). I’ve taken it back out (because of that problem), to check, and it was perfectly fine. I put it back, this time pushing it in straight and screwing both sides slowly. I did not see a screw on the side of the socket… in any case it slid in smoothly again and since I didn’t touch the screw it’s probably still locked.
And the metal plate seems to be something that held down the VGA cable from the screen.
I do have 3 screws left :s.
Anyway…at first, it kept rebooting when I turned it back on, which I noticed because I heard the CD-rom do it’s booting sequence over and over and over again. If I held down the power button it would stop, if I released it it continued. The only way to power down was to take out the battery.
After checking every connection, I decided to remove that plate and unplug the VGA cable : It boots perfectly. But I can only use a VNC connection to control it :s. So now I have to figure out why that cable is causing it to reboot.
At least I got the critical files of the system now, and the CPU seems happy so the problem can’t be that bad?
I’m curious now, why would you renew the thermal grease if it’s still sticking together perfectly?
nb:I’ve noticed my cleaning had good results the CPU cooler now runs for very short spurts, with long intervals inbetween, rather than just ramping up the speed and then shutting down completely.
April 29th, 2006 at 1:34 pm
Well, good news. I’m posting this from the reassembled laptop!
All I did was just plug the cable back in, and it’s working perfectly now!
It hasn’t shut down, no matter what I throw at it!
Oddly enough, I still have 3 long screws, and that metal plate left. And I haven’t been able to fix the keyboard, there’s one button (with the backslash, less than and more than symbols) that has never worked. And I actually want to give it 256mb more ram…any idea if a 1900 can handle 1gb ram?
If I can find time, I might do a writeup with shots of my “adventure”.
In any case, thanks for your support and information, cj2600!
April 29th, 2006 at 1:53 pm
Rygir,
Congratulations that you got it back and it works!
I’ve checked specifications for Toshiba Satellite 1905, I guess it would be the same for Satellite 1900.
Here is what I found:
Different Satellite 1905 models use different memory types. For example Toshiba Satellite 1905-S277 uses PC133 and the maximum amount of memory it can accept is 512MB. On the other hand, Toshiba Satellite 1905-S303 uses PC2100 and the maximum is 1GB.
I would assume that if your laptop used PC133 you can expand it to 512MB, if it uses PC2100 expand it to 1GB.

Thank you sooooo much for your posting on Toshiba Satellite 1905-S277…How to add ram. I have been seaarching the internet for days.
Thanks again.

May 6th, 2006 at 5:59 am
I want to add memory. Do I have to open BOTH the bottom and the keyboard just to add memory. If NOT both, which one?
Thanks
May 6th, 2006 at 9:00 am
Hey Bob,
By default, Toshiba installs main memory into the slot located under the keyboard. The second slot, on the bottom of the laptop should be empty and available for memory upgrade. You have to add more memory into the slot located on the bottom. It is not necessary to remove the keyboard.

Rygir…
)
Not to sure but does your Satelitle have the Wifi card fitted.. if so the the small bracker/metal flap is the securing bar (stops case flex from impacting the WiFi board)
You should be able to refit it by removing the cover over the board and slipping it back in. (now you will only have 2 unexplained screws (new spares

Hi,
Just wanted to thank you for the work you put into this site. I’d never have guessed that the second bank of memory for the 1905-S303 was under the keyboard!

Thanks for the helpful site. I am not a pc guru. Anyway I’ve been puzzled by the wireless switch since I got this toshiba and want to make it an internal wireless. How hard is it really? Can I install it and extra memory from the easy hole in the bottom or do i have to remove the keyboard?
August 21st, 2006 at 11:16 pm
Peggy,
You can install the wireless card if you remove the memory cover on the bottom. The Wi-FI slot in the same bay. You can see it on the step 2. There are 2 wireless antenna cables. The white cable goes to the main connector and brown to auxiliary.

Do you have instructions on replacing the CPU cooling fan in a Toshiba 1905-S303??
October 14th, 2006 at 6:33 pm
Interesting about that wifi internal card. I just opened my 1900 and saw that slot there above that memory, from underneath the laptop. I saw that there is a stick of RAM underneath the computer AND under the keyboard. Wonder if they are both upgradable? That would be awesome, total of 1 GB finally!!!
With regards to the wifi and the antenna, where exactly do I attach those wires to? the card itself??? Do they need to be soldered on?
Thanks! And your write-ups are amazing
Cheers

Steve,
Satellite 1900 notebook has 2 memory slots and you can use both of them for the memory upgrade. I believe that this model will accept up to 1GB of memory in both slots, so you can use 512MB+512MB.Toshiba Satellite 1900 is different Satellite 1905. Toshiba Satellite 1900 has only ONE memory expansion slot.
Here’s a nice memory configurator, you can use it to find out exactly how much memory you can install into your laptop.
The wireless card antenna cables run inside the display assembly, under the LCD screen. You can see an example here, on the step 10. You don’t have to solder the Wi-Fi antenna cables to the card. The antenna cables have small connectors that you can snap on the wireless card connectors.
October 24th, 2006 at 4:28 pm
Thanks for your help. Unfortunately, according to that memory configurator website and the actual Toshiba website, they say I can only upgrade to 768 MB
Wierd because they both list one of the memory slots as non-removable but I can remove both??? I don’t get it. Either way, thanks again for your help.
Cheers,
Steve

Hi Steve,
My bad. I assumed that Satellite 1900 is just a Canadian version of Satellite 1905 (I work with laptops sold in the USA) and it also has two expansion slots available for the memory upgrade. After I searched online I found that Satellite 1900 has a memory module integrated into the system board and only ONE expansion slot. The maximum memory size for Satellite 1900 is 512MB or 768MB, depending on the model.
November 11th, 2006 at 1:02 pm
I am disassembling my 1905 in order to re-solder the DC connector to the main board. I am to the point where the top and bottom parts of the laptop should separate, but I cannot get them to separate. I used a guitar pick and opened it from the front just fine, but there is something in the back near where the monitor posts connect to the laptop holding it together. I do not see any screws anywhere and I cannot figure out what is still holding this laptop together. Any ideas?
November 30th, 2006 at 10:17 am
Chad-
Hopefully you have solved your problem. There are two screws by the paralell and VGA port that are covered with plastic dots. Remove dots over screws and you should be in business.
December 9th, 2006 at 11:46 am
I’m trying to replace the DC Jack on my Satellite 1905-S303, I have removed all screws from the bottom of the unit, rear of the unit under the blanks, and under speaker covers. Are the screws under the keyboard? it seems to be stuck on both sides in the middle of the unit. Is the a diagram availible?
December 12th, 2006 at 4:53 pm
Carmelo-
You need to remove keyboard to get to remaining screws. There is a diagram on removing the keyboard on the original posting. I believe there are five screws. That should do it. I dissassembled my unit, but have not soldered yet. I am just going to resolder old jack as it is loose.
I also am cleaning out the heat sink, it was filled with dust. My CPU fell out when I turned over the system board. It did not appeared to be locked into the socket, and the huge heat sink makes it impossible to turn the locking screw. It is well anchored with the heat sink clamps, however, but a word to the wise once you release the clamps holding the heat sink, the CPU comes out. The sink is industrially glued so I guess this was the only way they could do it.

Hello,
I own a Toshiba 1905-S303 and I purchased a MSI6833B MiniPCI Wireless card. The card seems to install fine and I think i got it to start the Microsoft Zero Configuration correctly.
However, when I try to look for a signal it tells me that there are no signals available. I know that there is a signal available because I can find my router and connect perfectly when I plug in my PCMCIA card in.
I bought the internal card to get rid of any unecessary bulges to my laptop.
I have the white antenna cable in the Main and the black one in the AUX.
The solution for this problem has been published here.
January 19th, 2007 at 8:37 pm
Well, me again
After having a lot of problems with getting my Toshiba Satellite 1900 started again, I took it in to have it looked at. The tech guy told me “most likely, the motherboard is fried.” That being said, what are my options? Here is the link to my exact laptop on the Toshiba website: http://www.toshiba.ca/web/product.grp?lg=en§ion=1&group=223&product=321&part=513
Anyone know how I should part with the laptop now, as I assume it isn’t worth fixing? What could I get for it? Should I try and sell it as one piece or part it out? This sucks, I needed that laptop for school too
Thanks for your input.
Cheers,
Steve

Hi,
I know this is getting a little old but it’s the only site I can find with information so here go’s…
I see in your picture of the bay that holds the ram there is a cable already for the WiFi. I’d like to add a radio to my 1905-S277 but I don’t see the antenna cable in that area. Should it be there even though the unit was built originally without that option? Could it be tucked up underneath something that I can’t see or possibly I need to open the unit up further? If I don’t have an antenna already can I add one if I’m handy? Any suggestions would be appreciated. Thanx, Bob.

Hey,
I Have a Toshiba Satellite 1905-S301 and will like to replace the graphic card that came with the laptop to a better efficient one. How can I remove the graphic card safely, and which can I use in its place thats more productive but as small as the original one, or be able to fit in its place. I have a ATI Mobility Radeon X600.
Thanks,

Hey there,
Firstly, thanks for taking the time out of your life to make this website: I know what a pain in the arse they CAN be.
Moving on, I have a Toshiba Satellie 1900-110 series, or the one pictured above…anyway, I was wondering, what DVDs can I read from? Is it just normal movie rental and bought DVDs or does it include DVDs like DVD-RW and such…the manual just says it is a DVD-ROM drive, Read-Only-Memory.
Also, is it me or is the fan for the processor really loud in this laptop?
Thanks in advance, Tom.

Hi,
I need to replace the USB board on a Satellite 1900 (I guess should be the same as 1905). Do I need to be a master in resoldering or it is a quite easy thing to do?
It sells for around USD20.00 and I think it’s time to change it since both the ports are quite unusable
October 11th, 2007 at 8:05 am
Hi..Im having the same problem as Bob.. when I opened the bottom of my 1905 to install an internal wireless card.. NO antenna cables!… When I looked behind the slot, there is a little hole where they should come from the display. Does anyone know if they are on the other side of the motherboard near the power board?.. or still tucked away in the display unit itself?.. How do I take apart the display unit for this computer to find out?.. or does anyone know before I start?.. Can I just attach two antenna cables in the bottom and snake them around the mother board?.. Should I ground them to the metal frame?.. would this work?. .thanks for any help
October 11th, 2007 at 8:32 am
Nope, if the wireless antenna cables are installed, you should see them in the wireless card area. Looks like you don’t have these cables installed in your laptop.
You have to install these cables inside the display panel, under the LCD screen.

Hi all,
I have a Toshiba 1905-S303.
I have to resolder the power connector to the main board
Does anyone have any diagrams/pictures on dis-assembly of this unit to get at this power connector so I can solder it??
Thanks you soo much!
Sincerely,
Cindy
November 10th, 2007 at 4:01 am
Hi,
I’m also looking exactly for the same purpose,i’m half way through some where couple of screws are holding tight,not able to detach the board out.
November 10th, 2007 at 4:55 am
Hi-
Taking the 1905 is a b#tch. I don’t have my daughter’s had, but i had to resolder the power connector also. There are two screws that anchor the hinges. They are on the back near the ports as I recollect, one by each hinge. they are covered by small plastic dots. I broke one plastic holder for the metal hinge before I discovered my mistake. Super glue was able to repair that. Also be sure to remove keyboard and plastic strip but i am guessig you are past that poit.
Good Luck

November 10th, 2007 at 12:00 pm
Bob,
Thanks a lot for the reply, removed the two screws one next to eth and the other next to S-video still no luck.
Some other screws are holding the mobo to the case,this Adapter problem is a real crap with toshiba.
November 10th, 2007 at 5:02 pm
Hi,
I just wanted to post a followup to my previous and others comments. Mine did not have the antenna’s already. I bought a pair off Fleabay for $10. Took the monitor apart (thanks to this website) and installed them. I bought a minipci card there too and put it in. Unfortunately, the card wouldn’t work. After snooping around on the net I read you have to block off one of the pins with a piece of tape. After I did that we had liftoff! I also replaced my two 128mb chips with two 512’s. The back one was easy of course. The one under the keyboard was a little more difficult. Instead of totally dismantling the laptop I just removed the keyboard. Below it is a very thin metal sheet. With some careful snipping with a pair of heavy scissors I cut out around the chip. Pulled it out and replaced it. Put it all back together and now we’re smokin with 1gb of ram. The difference was HUGE! I also wiped the drive and did a fresh install which sped it up even more. This PC has been problem free for me since day one and I have been more than pleased over the years.
January 8th, 2008 at 6:38 am
Hi, I have a Toshiba Satellite 2450-101 and I want to upgrade the RAM, will u be able to tell how to dismantle and install the RAM
your response will be much appreciated.
Please send me a copy of the solution to the above email.
thx again

January 8th, 2008 at 11:16 pm
Chaudhry,
I don’t remember this model, it’s kinda old. I think you should be able to access the memory slot from the bottom of the laptop if you remove the hatch.
March 7th, 2008 at 4:59 am
I’m also looking to upgrade the memory on my Toshiba Satellite 2450-101. According to the manual I can only upgrade up to 1G. (2 x 512M as there are two slots).
Is there a possibility that I can upgrade up to 2G (2 x 1G)? Is there a motherboard or other compatibility issue?
I think Toshiba Satellite 2450-101 came with 2 x 256MB-DDR266, 266MHz, PC2100, 200p SODIMM, 2.5v, Sync

BoB O,
I am trying to clean up my Satellite 1905-S303 due to frequent over-heating shutdowns. But I am not sure if I am trying the correct places (this is the first time I work on a laptop) — does the heat sink sits near the fan? I opened the cover using T6 and saw couple of more screws. I removed them too, but then I found I still couldn’t get the thing out. Did I work at the wrong place? (I also tried to access the fan, but seems I have to unassembly everything, which I am not comfortable with now, so I stopped) How could I solve the problem? Thanks a lot in advance for any help you might give.
By the way, do you have assembly pictures for S303? it would be a great help if I can have some diagrams. Then at least I know what is what.
Thanks again for any help I might get.
July 29th, 2008 at 4:33 am
This is Eva again. I post a message for help to clean up my Satellite 1905-S303 but didn’t get any comment yet. Recently the laptop encounters frequent over-heating shutdowns. But I am not sure if I am trying the correct places (this is the first time I work on a laptop). Any help is highly appreciated. If you have assembly diagrams or service manual for s303, that would be a big help too.
Thanks very much for your help and look forward to your replies.
July 29th, 2008 at 11:50 am
Eva,
There seems to be several problems that can cause problems with the 1905. One you have read about is the heat sink. It may just need cleaning. You need to continue your disassembly to get to CPU. The instructions on the web site are there, but you have to read several of the e-mails. Once you get the plastic strip off ( the one around the power button snaps out) it is fairly straight forward. There are also two covered screws I had difficulty locating one next to phone jack and one next to s-video port. They allow you to separate the screen from the rest of the unit if you want to work on the motherboard.
I have recently had overheating problems, but I think mine is related to the power jack (big problems on these units). You notice it less if your battery is still working. Have you had overheating if you just use the battery? The power jack is not soldered well and breaks loose from the motherboard. This causes the power to short at times and shut your unit down. You dont’ notice it if your battery is good. I resoldered my power jack, but I think that after the unit heats up it can cause it to short out again.
Resoldering the power jack is not that difficult. I was a total newbie, but I bought a cheap iron and did it ( Although It maybe still loose as I was reluctant to get too much solder on the connection). You probably could take it into a shop and have it redone. Mine is working OK, So I am just going to relace the battery and not run the power except to charge the battery. You can check the connection by moving it up and down and see if it changes the battery setting (i.e does it not detect AC power).
July 29th, 2008 at 12:56 pm
Bob O,
I also have a Satellite 1905-S303 that has a bad power connector.
Can you please tell me how & where to find the info about taking it apart in order to resolder the connection? Does this site have any diagrams for doing this?
I can only find info for replacing memory modules.
Thanks a bunch!

Thank you so much for your reply! I was out and just saw it.
I believe my laptop’s problem is due to dirty heat sink, cause the battery is almost dead. But I still have problems with disassembly. Do I work at the right place? I couldn’t find any instructions, nor diagrams. Since you mentioned plastic strip ( the one around the power button snaps), I guess I am working at the wrong place. Could you please give me some detailed instructions/diagrams or links for instructions/diagrams? Like Sue said, the only info I could find is for replacing memory modules. I found some diagrams on how to clean hear sinks of other laptops, but seems not that useful.

I don’t have any diagrams. If you read other posts in this dicussion (i.e. 6 ) I don’t have a link to a complete 1905 dissasemby, but if you remove screws and follow steps it comes apart. I did find a link for a toshiba power jack replacement.

I would say that if you remove the screws much of the steps are fairly obvious. If you run into problems someone can usually help you out. If you are not comfortavle than again Iwould suggest your local repair shop.

Dear Bob,
Sorry for my late response, I was out and came back very late last night.
Thank you very much for the tips you gave, the diagrams will help a lot, but you are right – remove screws and follow steps it will come apart. I was just lazy and dreamed to get it done a easy way. I will try to fix it this weekend. If I encounter problems, I will ask again.
You have a great weekend.

Hi, I have little problem with my old Toshiba 1905-303…
I took it apart to replace my not working fan. Now I put everything together and the computer boots up but the screen is not working…
Any ideas why? Any help would be greatly appreciated..

Hi,
Recently, for about the last six months my 1905-303s shuts down. As I have read heat appears to be a strong cause of the problem. I regularly dust the underside exterior fan screen but I’m coming to the conclusion that other permanent solutions will be reqiured.
Questions:
If upgrading to 1G of RAM will this cause it to run cooler or warmer?
Would setting up a small independent fan pointing to the laptop fan be of any benefit?
Is there a mini-vac that can extract any internal dust present beyond the external fan screen? I’m familar with canned-air but curious if a product vacs as opposed to blows?
This is my angural debut to this specific problem and any feedback would be much obliged.

I have a Satellite 1905-S303. I ordered the recommended Kingston 512MB memory, and followed the instructions here (and in the Toshiba User Guide. Note that the Guide tells you to use a Phillips #1 screwdriver to remove the screws, but that’s too big, and could cross-thread the screws. You need a Phillips #0 screwdriver.)
I found a memory chip already in the slot on the bottom of the computer, that is supposed to be empty. So, following the instructions here, I removed the keyboard. (Don’t forget to remove the battery first.) Low and behold, the supposedly “unremovable” memory chip there IS removable. I realized that Toshiba initially loaded 256Mb memory chips in EACH of the two slots, to get its advertised 512Mb, along with a so-called upgradable memory slot. So I now have 768 Mb, and will have to purchase ANOTHER 512MB memory chip to get up to 1Gb. Thanks for ripping me off, Toshiba!

I have a Satellite 1905 that I can’t get the cover off to get to the motherboard. It seems to be hanging up at the center back. I have taken out the 3 screws on the back. I don’t want to force it as this computer is not mine. I need to repair the DC connector. Any ideas? Thanks.
