Compaq Presario C300 Overheating Problem

Ballymun Bohs

Like the thread title says, if running processes for a reasonable period of time it starts to heat up quite quickly. The fan becomes very loud (trying to cool it down I assume) sometimes it has shut itself off, I know that this is a precautionary measure. The machine itself is working fine it's really quick and smooth. I have opened it up to clean any visble dust out from the inside and also making sure not to touch any internal parts. I'm just seeing if anyone has any advice on how to maybe solve this issue.

Thanks in advance.

I assume ur fan is not working properly and u have to swap it

check if there is enough strong air flow form air intake. have u checked heatsink? Maybe is blocked with dust.

I've got the same problem with my Compaq, though I haven't opened up mine yet. It looks like it could be tricky :eek: The biggest culprit for laptops overheating is when the vents get clogged up with dust and fluff. I've heard some people recommending getting a canister of compressed air (available in computer shops) and blowing the vents out with it. Didn't work for me but it might be worth a try.

Yeah, most of the time the dust and hair is to thick to get throught the heat sink. Compressed air just won't sovle the problem. The laptop will need to be dismantled or partly dismantled to remove all the dust. If your up for it give dismantling it a go. When dismantling label all the screws you take out into groups and you should have no problems.b

I have taken all the screws out of the back that I can visably see. When I tried to remove the plastic case from the bottom of the laptop however it seemed to lift up relatively easy at the corners but it wouldn't fully come off. I've more than likely done something wrong but I'm not sure what. There are individual covers which can be removed, one for the hard disk and the other for what looks like to be the processors. I have blown any visible dust away that I've seen when I've removed these covers, not with compressed air though, using my own lung power.

I do have software on the laptop which monitors the heat of the various components. The laptop tends to get really warm when the processors reach temperatures of 65 degrees C or above. I'm not sure what the ACPI is but it fluctuates between 5 degree intervals normally, either 65 or 70 degrees when up and running. The hard disk temperature normally goes upto about 50 degrees.

The place you want to get to is between the fan and the heatsink. The other side of the heatsink should be visable from the outside of the laptop. Ya may have to remove the keyboard to open the laptop further.
