Question about Toshiba Satellite A105 Notebook

1 Answer

Put US-made 120 V Toshiba into 240 V electric current. It blew.

In error I put a Toshiba Satellite A105- S2081 into power socket in Australia, which is 240 V, without adaptor, and it blew. There was a puff of smoke and it went dead. What damage have I done?. Can I replace a part or two? If so, what parts are likely to have been blown or damaged and can they be replaced. I have taken the machine apart and would like the experience of trying to fix it myself. 
If I cannot fix with individual parts, would like to get a new motherboard. What one would work with this model?
Kind regards,

    Wow Cenobite, that was really fast. I only just posted. Thank you for replying. 

    The smoke came from the side of the computer. I mistakenly plugged in with a cable that did not have an adaptor, hence it got the 240 V instead of the reduced 120 V. The computer then went dead, and will not come back to life.

    So, if the "power stage" of the motherboard cooked, what parts exactly are we talking about here, and can I buy replacements?. I would like to try and fix this machine for the fun of it and for the experience, even if it means putting in a new motherboard. Like I said I have painstakingly taken it totally apart over many hours today, and would like to see it through. The screen is 15", and a very good one, and there is 2g of ram, etc and etc, so it might be worth the effort.

    With thanks again

Did the smoke come from the computer or the power supply. Most of the power supply boxes for notebooks are multi voltage and can auto switch from 110 to 220. If the smoke came from the power supply box it may not have damaged the computer. If it came from the system, the power stage of the motherboard cooked and it will need replaced. If it is an older laptop it will probably not be worth fixing as it may cost more than half of the cost or a new one. I would try using a different power supply to test it and see if it comes on. If not, you may be looking at getting your data transferred to a new computer.
Best of luck

    You would have to get a motherboard from Toshiba for that model. All notebooks have proprietary motherboards for each model or model family. They can be quite pricey. Call the Toshiba support centre and see if they will sell the motherboard to you. It is possible that there is a separate power stage, but I am not sure. You could also look on Craigslist and see if someone has that same model that they are selling because it has a bad screen or whatnot.

    Hope that helps a bit.

The lower 1/3 of the screen on my Toshiba Satellite A105-S2081 is distorted. It changes from a hazy appearance to full distortion of the picture by moving the screen. Is the screen itself the...

If it happens when you move the screen up or down, it is the LCD cable. It may have loosen from the system board.

IS there any factory seeting hidden in TOSHIBA

On some models of TOSHIBA laptops you can access the system restore partition by tapping on the 'zero' (0) during boot.

This will erase EVERYTHING on your drive and reset it to a "out of the box" state. So be sure to back up anything you want to keep before doing a system restore.

Toshiba Satellite A105-S4064; can't get battery to charge

If you put strain on the jack (e.g. hang power adaptor from it whilst using or charging) then the socket on the mainboard can get hot due to poor contact and melt.

There is no way to fix this except to completely dismantle the laptop and fit a new socket - most likely a repair centre will charge you for a new mainboard.

Try another adaptor to see if that is the problem (broken wire in cord) - otherwise look closely at the socket in the notebook.
