Toshiba Satellite A105. Removing laptop motherboard.
Yesterday I had my first experience with Toshiba Satellite A105 notebook series. I had to replace the laptop motherboard because it was completely dead. The disassembly was easy and fast. I like the way this model was designed. Laptop disassembly instructions.
What I like in this model: The hard drive has a very nice rubber protector. Both memory slots can be accessed from the bottom of the laptop. There are no screws under the keyboard and it saves some time during disassembly. The power jack connected to the motherboard via cables and if it fails you do not have to replace the entire motherboard. There are very few cables connected to the motherboard. The laptop disassembly process is very easy and logical.
What I didn’t like in this model: There is no hatch for accessing the CPU fan and the heatsink without taking apart the laptop. It took me some time to remove the top cover assembly because of some hidden plastic latches. It is not very easy to disconnect the video cable from the motherboard. The touchpad has 2 cables connected to the system board. The second touchpad connector is hidden under the flat cable and can be easily overlooked during disassembly and the cable can be damaged.
Here’s another guide for this model. Removing laptop LCD screen.

sathika,
I don’t have a guide for this particular model, but it could be similar to one of newer Satellite M-series laptops here: http://www.irisvista.com/tech/
Test your laptop with an external monitor. Will it work fine with video on the external monitor?
Check out if there is a newer version of BIOS for your model on Toshiba website. Sometimes updating the BIOS helps.

raskafery,
You are correct. This model can set up the BIOS password on its own.
In this post: http://www.insidemylaptop.com/toshiba-satellite-a105-laptop-sets-bios-password-by-itself/ you’ll find a couple for links to the instructions.
Alternatively, you can call Toshiba and explain what’s going on. They will remove the BIOS password at no charge even if the laptop is out of warranty.

How do remove the satellite A105-s4134 Colling fan????
January 25th, 2010 at 3:49 pm
I have an issue with my Toshiba Satellite A105. Recently my microphone “jack” went out. When using a chat program (like Paltalk) I am able to hear everything perfectly, but I am unable to utilize my microphone jack when I try to speak.
When I go to my control panel, click on “Sounds and Audio Devices” and click on my “Voice” tab, I attempt to turn up the volume on my microphone. But it does not work. No volume when I attempt to speak. I have check all my mic cabling, microphones and they are all good.
Furthermore, I attempted to re-download the appropriate drivers from Toshiba, thinking it was a driver problem. But again, after successfully doing that the problem remains unchanged. No ability to use microphone as my mic jack remains faulty.
Could this be a problem with my motherboard? In other words, could I have a short on my motherboard? If so, is this something that I can fix on my own? If you could get back to me on this I would greatly appreciate it. Thanks again.

Rijofe,
Did you disconnect the cooling fan from the motherboard while cleaning the heat sink? Maybe you forgot to connect the cooling fan to the motherboard?
Turn on the laptop and listen for the fan. Does it make noise? Does it spin?
Also, did you apply new thermal grease on the CPU before installing the heat sink?
January 18th, 2010 at 6:36 am
I have followed this instructions (that are very good, by the way) to clean the heat sink that was clogged causing overheating and it used to shut down because of that. Now I have a new problem: the computer is not overheating anymore but while using the computer, it goes off unexpectedly. Strangelly, if I turn the computer on and leave it on with no use, it does not goes off but when I start to using it, sunddely it goes off a few minutes later. Could anyone help me here? Thanks

My monitor on my Toshiba A105 went out. I was told it was the video card/graphics card. Connecting a monitor to the laptop did not work. Do I have to replace the entire motherboard? Thanks in advance.

I have a Satellite A105-S4334 that has the power button pushed in (broken). Can anybody guide/refer me to the steps to replace what I’ve been told is the 6 button switch board?
Many thanks in advance!

boston,
I’m using regular “Blow Off” duster shown in this picture: http://www.insidemylaptop.com/images/HP-Compaq-6515b/remove-keyboard-clean-fan-08.jpg

re: cleaning with compressed air – can you use the cans of compressed air that have that bitterant additive or will it leave a damaging residue behind? or must one use the can specially designed for camera lenses and chips that have no bitterant added? thanks!

Hi, I’ve discovered that it is easier to remove the upper keyboard strip than is illustrated. Simply remove the battery from it’s niche and there are four snap tabs that hold the keyboard strip to the notebook body. Unsnap those 4 tabs then turn the notebook back over and gently lift the strip from it’s center area (you’ll need to lay the screen back), lifting from both the top and bottom sides of the strip. This will allow the infamous side tabs (the ones about 1/2″ in from the sides of the computer)to want to disengage from their slots much easier.

SEAL,
it’s not a chip, it’s two pads on the motherboard. Looks in the memory compartment on the bottom, or under the wireless card under the keyboard. Depends on the model.

Hi Man, very usefull this article, tnx my friend!!! i’m newbie but this is so great!!
greetins!!!

Martin,
I believe that Satellite A100 and A105 laptops have the same (or very similar) body. In satellite A105 you cannot access the CPU and replace thermal grease without removing the motherboard.
Yes, you’ll have to disassemble the whole thing.
By the way, have you tried cleaning it with compressed air? Spray it inside the air intake on the bottom. This will remove most dust from the cooling module.

Hi,
I’ve got an A100 – 936, and I think I need to clean the CPU/renew grease due to overheating. My Question: To get access to the CPU, do I need to take the whole notebook apart? and is the guide for A105 notebooks also useful for my A100 notebook?
Thanks in advance!

Deborah,
Sounds like you have to install drivers for XP.
You can download missing drivers form Toshiba support site (click on Downloads tab).

Jason,
Satellite A105 has a few different designs. If the wireless card in your laptop is not on the bottom, you’ll find it under the keyboard.
September 28th, 2009 at 8:47 pm
I followed your instructions for an A105-S4084 toshiba, but the wireless card is not where the pictures say it should be. The modem is there but no wireless card.
Ideas?

OOPS! Accidentally hit submit before I was finished with my list. These also have exclamation marks beside them in Device Manager…
Modem Device on High Definition Audio Bus
Video Controller (VGA compatible)
Any ideas? Do I need drivers, and if so where can I get them so they will work since this was running Vista from the factory before I downgraded to XP?
Thanks!

Hi,
I have a Toshiba A105 S2236 that I reformatted and downgraded to XP from Vista. Now everything works fine except I can’t hear sound and games (except those really basic Windows games that come on every computer) won’t work. In Device Manager it shows yellow exclamation marks for the following devices:
Audio Device on High Definition Audio Bus
Ethernet Controller

Nice workup on the dis-assembly guide for the A105. I have a Toshiba Satellite A105-S2081 with a loose DC jack. I found another thread, on another website that talks about buying a metal DC jack from Radio Shack. I was wanting to know if that will work on my laptop? The link to that thread is here…

Hello Again Sir!
I have discovered a situation with my laptop problem. Everytime I use my laptop with the power cord connected to it, my toshiba m200 laptop is either system stops, or hangs with garbled display. However, If i’m using only the power from the battery, it goes well. Please anybody can help me with this?
Thank you again in advance! More Power!

Hello Sir,
I am having problem with my Satellite M200 laptop. sometimes the system hangs, sometimes it reboots by it self, and sometimes i’m having garbled display and it hangs. I bought and tried to install a laptop cooler pad, thinking that it would resolve the problem, but unfortunately i still encounter the same problem. Can you help me identify the possible causes for this problem.
Thank you in advance!

Ricky Hermogenes,
Back up all personal data and reimage hard drive using the recovery disc. This will load everything back to factory defaults. If you still experiencing the same problem, it’s definitely a hard ware problem. Most likely bad sound card.
I don’t think so. The sound card is integrated into the motherboard and cannot be removed. If the sound card is bad, you’ll have to replace the motherboard.
