Acer Aspire - How to dismantle?

post #1 of 6
Thread Starter 
Hello,

My CPU is getting too hot. It's around 72 Celsius degree at 20% load. I think, it's simply because there are a lot of dust on and around CPU fan.

So, I have to clean these dust, but I have almost no idea about how to dismantle my Acer Aspire Ethos 5951G. There are no video guide or there are no guide on the internet that I can look at when dismantling.

So, please help me.

I feel like the only option left to me is that I remove all screw that I can see and I try to remove covers. But I am afraid of using too much force and damaging some covers (when bending covers in order to remove)

As a general rule, remove all the screws underneath, remove compartments on the bottom, remove the keyboard, remove screws on top, prise apart the two sections, remove the fan assembly, clean it, replace TIM and any thermal pads then reassemble.

You shouldn't need to "dismantle" the laptop. Just unscrew the few screws holding in the back panel and pop it out. This should revile the main motherboard area that includes the cooling fan an heat sink. The fan should be removable by taking out 3 or 4 small screws. After this it should be fairly easy to do a thorough cleaning of the heat sink.

I haven't taken apart an 5951G my self but that's usually all that is needed on regular laptops (that's how it is on the 7520G/5520G for example).

Very few laptops have easy access like you describe, most of the time you have to remove the whole motherboard to get at it! I swear they do it on purpose to make extra money!

Hopefully yours is one of the few that have a compartment you can remove for access to the fan.

If its overheating that much though, I suspect a TIM replacement would be highly benefical too. I have repaired loads with IC Diamond 7 with overheating issues:thumb:

OP,

If accessing the heat sink itself is too difficult, you can always use compressed air and spray directly into the exhaust vent when the laptop is off. This is usually the technique I use when I clean out laptop air vents and heat sinks.

Some caveats:
Use short bursts to avoid spinning up the fan too much. *the spinning fan can generate stray electrical current*
This technique is not recommended for cleaning heavy dust build up (first time cleaning out exhaust vent after 1+ year of use).
Also, some of the dust might be pushed further into the crevices of the laptop (dust being deposited onto mainboard)
