Having problems with your Toshiba Satellite A75-S226 Notebook ?

Toshiba Satellite A75-S226 Laptop gets warm and shuts down.

\015 Screens are clean on outside fan ports. Have recently cleaned these a few times on the outside. Is it easy to take it apart to clean it inside? Or do I have to send it back to the dealer to get it cleaned. It was already sent back once when it was under warranty. I am a retired System engineer, former electronics technician and now 75 years old. Still fairly good at repairing electronic equipment. Is this a job I should undertake? Anyone having worked on this problem, Please advise.\015

Answers :

When you take it apart your probably going to find dirt on the heatsink next to where the cpu fan vent is.

Its not that its hard to take apart but its alot of screws that need to come out and you need to keep things in order.

First all the screws on the bottom need to come out, then take out the hard drive, dvd drive, any doors covering memory, wireless card etc.

Then the keyboard cover needs to come off and then that should expose the screws to take of the keyboard. The other end of the keyboard is help in by a ribbon connector that needs to be loosened and that will take the keyboard out. The any other screw that you see on the top cover need to come off. The 4 screws holding in the lcd need to come of and then if there are wires that are being ran to the wireless card, those need to come loose as well cause they are part of the lcd.

There maybe a few more conectors for the speakers and a ribbon cable for the mouse pad that need to come off.

After all of that you can get the top cover to come off and that will expose the motherboard. There maybe a few screws that need to come off from the motheboard.

Then at that point you can get the motheboard away from the bottom assembly and at this point you can unscrew the screws from the cpu heatsink and then clean off the heatsink.



Taking apart any laptop can be a pain. Just make sure you know where\015\012each of the 50 screws go and what is a screw or fastener and what is a\015\012clip. Also be careful of any ribbon cables and other delicate things\015\012inside. Clearances are tight and you need small fingers at times (I\015\012use hemostats for a lot of things.) You may also be able to find a\015\012manual online that will describe disassembly, sometimes even from the\015\012manufacturer.

\015\012The heat issue may be a hardware problem. Most modern Laptops use a\015\012heat pipe to transfer heat to the heatsink. It uses a coolant that as\015\012it heats up, it changes states and goes up the pipe, cools off and\015\012changes back to a liquid. The pressure is adjusted at the factory and\015\012is not servicable. If the problem persists, check this and the fan.
