Problems with 6214W (want to remove dust)

My 6214W has started shutting down when playing some games (Civilization 4 latest). I have had time to get the temps yet but they are usually around 90+ when playing for example Wc3.

The laptop is more than one year old so the warranty is gone, so I figured I might as well try to clean some dirt from the inside. I've used it in my bed several times so I'm sure there's some dust. I've used compressed air, but I consider that more as a temporary solution.

I've tried to open up the laptop, but I can't get the keyboard off. I've removed the screws (the one where the RAM is as well), but I haven't managed to "slide" it off as some have explained it.

Could someone give me a thorough explanation (preferably with images) on how to remove the keyboard on a 6214W? I would assume it's the exact same procedure as on the 6224W.

 

Here is another thread which describes the keyboard removal. I suspect that you haven't managed to unseat the little tabs along the front of the keyboard. You need to prise the front edge of the keyboard backwards by about 1mm at the middle and near each side in order to unseat these tabs. Then lift the keyboard slightly at the middle of each side where it is held down by a small nib in the chassis.Then lift the front of the keyboard up enough to be clear of the palm rest and slide the keyboard towards to front enough to release the back edge. Then flip the keyboard over.

Thank you!

If I were to undervolt using RMclock for example. How much would I loose in terms of temperature and performance?

 

Undervolting does not cost you any performance: You are dropping the operating voltage but not the speed.

How much temperature drop will depend on (a) how far you can undervolt your CPU and (b) the contribution of the GPU towards the total heat generated. Typically, people have reported a 10C reduction in CPU temperature. If your CPU is currently running at around 1.25V at its full speed then the potential for temperature reduction is big. Almost all the Core / Core 2 series CPUs seem to be able to run stable at less than 1.10V.

I used RMclock and managed to loose 10C

I took a little fiddeling since I use Vista x64, but I managed. I will probably wait with dusting off the machine, since I'm afraid of breaking the keyboard

 

Glad to hear that you have got the temperatures down a bit. What are the maximum before and after voltages for your CPU?

It was set on 1.25V for all modes, and I switched to 0.975V on battery and 1.1V for high performance. No bluescreens yet.

I haven't taken any exact temp measurements, but Primo95 used to cause degrees of around 93C, and now it stays at about 83C.

While playing CIV IV, which caused the laptop to shut down, I'v gone from 98C (max) to 92C.

 

Here's a useful guide for setting up RMClock.

I've got my T7200 running at 6x 0.95V to 12x 1.05V (in interpolation in between), but you should do some stress testing. I think mine BSOD'd at 1.025V so I've got a little headroom.

That Orthos program slowed my computer down immensely even after I stopped the testing, so I will probably stick to Prime95
