Acer Aspire 3620 disassembly

In this guide I’ll be taking apart an Acer Aspire 3620 laptop.

This particular computer

was shutting down by itself while running some intensive applications. I found that the cooling module (heat sink and fan) is completely clogged with dust and needs a good cleaning. Unfortunately, in this model the cooling module is buried deep inside the laptop case and it’s necessary to take the whole thing apart in order to access it.



ШАГ 1.

First of all turn off the computer, unplug the power adapter and remove the battery.

Remove the hard drive and memory covers from the bottom.

In order to unlock the connector, move the brown retainer about 2-3 millimeters towards the palm rest.

Do not disconnect the retainer from the connector, it must stay attached to the base.

Now I’m going to remove the heat sink.

Remove five screws securing the heat sink and carefully lift it up.

As you see, the heat sink is completely clogged with dust. I’m going to use compressed air to clean it.

Heat sink removed

If thermal grease on the top of processor looks dry, you’ll have to replace it with new grease. Otherwise, you can reuse old grease, just spread it evenly on the top of the processor and install the heat sink back in place.
