Taking apart Toshiba Satellite M105 notebook
This guide will help you to take apart a Toshiba Satellite M105 notebook. You are welcome to post any tips and comments about taking apart/fixing or upgrading this computer.
This model is very similar to any other modern Toshiba notebooks.
Hard drive, CD/DVD drive, modem, wireless card and one of the memory modules can be easily accessed from the bottom. In order to get to the second memory module, you’ll have to get under the keyboard as it shown on the steps 9-15.
In order to remove and replace the cooling fan, you’ll have to remove the motherboard. If you feel uncomfortable doing that, take your laptop to a professional repair center.

On Toshiba M105 power issues. I have similar problems, unit will shut off after about 1 second or two and battery does not appear to charge, this was with unit plugged into the AC power supply. Wiggling the DC cable caused the charge light to come on. Thought it was the external power supply so cracked open the case and found +vdc wire twisted/broken by the strain relief. With the ends temporarily spliced, tried again, same problem. Laptop will shut off and will not turn on until remove and reconnect DC Charge cable. Connected an external LiOn battery that is used to keep Laptop on when internal battery is dead (Like the Xtend Universal External Laptop Battery that connects between external DC Power Supply and the laptop), same problem. HOWEVER, if I take out the internal battery, it starts up and works. The laptop battery is a little over 5 years old.

my m105 wont turn on. battery is out, ac/power is plugged in. ac power light is blue. hit power button will light the power led, then it goes out in 10 seconds. no bleeps, no fans spin, no dvd drive opens. i wish there was a fix but i’m guessing motherboard is toast.
at least i found the 2nd ram slot. thanks for the guide.

Thank you very much for this excellent guide. I have a problem where the display flickers on and off unless the lid is in a certain position. This guide will help me fix it without fear of breaking anything as I try to pry apart the wrong parts in the wrong order. Before I start I have to print everything of course. I found that to make use of your guide I had to put together three guides (One for the M105 I have, another from a different model where you take apart the lid, plus your “few things to know” guide). Then I had to expand about 10% of the pictures to make use of your red highlights. Most of the pictures don’t need expanding. So I put it all together into a single document with the pictures I need, the lid included, and all your instructions. That would be the ideal format for all these guides. I’d be happy to share the one I made.
Thanks again for doing this and making it available. Great explanations, warnings, gotchas, and pictures.

rich,
The CMOS battery soldered to the motherboard. You can see it on picture in step 22. It’s between the PC slot and Intel chip.
In order to replace the battery, you’ll have to remove the top cover, desolder the old battery and solder a new one.

Jonah,
First, try blowing it off with compressed air.
Find an air compressor your use your vacuum blower and blow air into the air intake on the bottom.
It’s possible the fan is blocked by dust.
If it doesn’t help and the fan will not spin, most likely the fan is bad and has to be replaced. In this case you’ll have to disassemble the laptop.

hi, my fan isnt working at all, i now have to use external fan which i dont think it is working at all, coz in about an hour the laptop will turn off by itself.. is it possible dusts are covering the fan or the heatsink? n do i have to take everything apart just to clean them??

Jonathan,
Did you read through the entire guide? The guide has 4 pages.
Read though the entire guide and you’ll get the idea how to replace the motherboard.
There are navigation links on the top and bottom of the guide: Page1 :: Page2 :: Page3 :: Page4

I need to replace the motherboard of a Tecra A6. I removed all the screws and components from the bottom of the notebook but stiil can not open it. The 2 screws at rear were removed as well. Could take it apart only at the rim but it seems to stay strongly attached somewhere. Do you maybe know what i am doing wrong? Is it right to open the bottom if i want to replace the motherboard?

Steve,
Check both memory modules. Make sure that both modules installed correctly. Try reconnecting them.
It sounds like one or both modules are not seated correctly.

installed two 1 gig chips of ram in my Toshiba Satellite M105-S1021 laptop. Followed all instructions and replaced the 512 mb under the keyboard and placed a 2nd 1gig chip from the underside slot. I get a black screen when I start it up. I hear a little activity for perhaps 5 seconds and then nothing. The fan runs too. What might the problem be and how might I fix it please. The chips came from Crucial and they were ordered after a scan of my computer.

Preparing for RAM upgrade on Toshiba Satellite M105-S322. I need to keep my notebook running for a while longer but can’t run my current apps without more RAM. I couldn’t find the second RAM location. Under the keyboard! I’m so glad I found your site. I just finished reading all the comments. I experienced the horrible spontaneous bios password issue in 2006 and got it repaired while under 1 yr warranty. I updated BIOS and noted that Toshiba is acknowledging the password problem. 2007 battery recall resulted in a free battery but it now holds zero charge and I don’t want to spend the money to replace it. I’ve had software issues and reformatted the HDD a couple of times. Fan runs more than I think it should but the screen and keyboard are holding up. With more RAM I will keep it alive a little longer.

Perfect, was able to reset the CMOS!

Nikki,
The backlight bulb mounts INSIDE the LCD screen. Check out this post: http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/

I replaced the inverter for my failed Backlight problem – it was not the issue, has to be the bulb. I bought a bulb… and I CANNOT FIND THE BULB inside my laptop! (Toshiba M105) I don’t get it… does anyone know WHERE it is located?!?!?!? Due to the Holiday and my lack of a Laptop when I’m not at work… would be great if anyone knows this. THANKS!

Sounds like bad power jack.

hello, first of all, excellent guide, helped me remove a ton of dirt and dust from the processor fan on a toshiba satellite m105 s3011 i have, but sadly it didn’t solve my problem, by the way, my m105 does this weird thing when i turned it on the other day, first it started by turning off randomly when on windows and i thought it was a thermal issue, but i got a chance to run thermal monitoring software before a shutdown and the processor was like 50c which granted, its not cool for a yonah but its not really hot either, then the laptop refused to even show a post screen, when you turn it on, the power led will stay on for maybe 5 – 10 secs and then it will turn itself off, its not a batery problem, does that when purely on ac power too, and aparently its not a thermal problem since i disassembled it and replaced the thermal paste on both the processor and chipset, cleaned the exhaust and the whole laptop, but the thing is the power led does this strange thing when you try to turn it on: the led will cycle between blue, orange and a bright blue/white and will do this until turned off, its not a memory issue, i tested it with other memory modules and in both the memory sockets i personaly think its the mobo or the processor…any help deciphering the led code please?

Alex Daudsyah,
These cable are antennas for the wireless card. You’ll have to connect both cable to the wireless card. White cable – main connector. Black cable- auxiliary connector.

I love this site! Awesome instructions and I was able diassembly by following all 32 steps.
I’m having problems putting everything back together in step 17.
I inadvertantly unplugged the wire from the LCD screen that goes somewhere. It is the two black/white wires with very tiny round ends. Where does this round ends plug into? I’ve looked everywhere on the motherboard and cannot plug this wire back in during assembly.
Any assistance would be greatly appreciated!

Thank you so much for this guide.
It helped me remove dirt on the fan so than my old M100 computer works fine now.

I followed a subset of the directions in order to get to the memory module under my keyboard. Battery out, then picking up with keyboard bezel, keyboard, memory cover.
Here’s a couple of clarifications.
1) I found that in prying off the keyboard bezel, a much better place to pry with a flat blade screwdriver is just above the top row of keys. Starting with the rightmost keys, as you depress the keys, you’ll see a spot that accepts a flat blade screwdriver. Slide it in the depression and lift and twist. Work your way to the left.
2) The instructions made me aprehensive about removing the keyboard connector (if you damage the connector, you need a new motherboard), so I tried to carefully follow them exactly as written. So please understand if it appears I’m splitting hairs.
The keyboard connector “lock” is actually a pair of locks, left and right, independent of each other. To unlock, the tabs are moved to the rear (towards the hinges), not “up” as in the instructions.
The ribbon cable moves in the same direction (toward the hinges) in disconnecting.

Thank you for this great guide! Without it my husband would not have been able to upgrade the RAM in his laptop …
But what bright spark at Toshiba thought that having to pull a computer apart to upgrade RAM was ok?
