How to dismantle Toshiba Satellite A70/A75. Repair laptop yourself. Disassembly manual with pictures.
This guide will help you to dismantle and repair a Toshiba Satellite A70 and A75 laptop. If you experience an overheating problem, you can use the guide to clean up the cooling module and remove dust from the heatsink. Also you can use the guide if you want to remove and repair the system board and resolder the DC-IN jack.
Here are a few known issues with this model:
1. The heatsink easily gets clogged with dust and lint and because of that the laptop may overheat and shut down without any warning.
2. Overtime the power jack might loose connection with the motherboard and because of that the laptop stops charging the battery or switches between the AC and battery power on its own. To fix the problem you'll have to resolder or replace the power jack.
3. The top cover assembly might be improperly grounded and because of that the laptop freezes or shuts down when you touch the speakers or touchpad. In this case you'll have to replace or modify the top cover.
