'Battery Alert' appears before the 'press 'ESC' key for Start-up menu.', however, ' Cooling Fan Alert' appears after 'press 'ESC' key for Start-up menu.'

Based on the screen shots you provided I see at least a 10 degree C temperature drop under the similar loading conditions.

If if was me I would not use paint thinner to clean the CPU and heat sink / Fan. A good alternative would be 90% isopropyl alcohol using a lint free material to wipe off "All" the thermal paste and then re-apply the paste.

Another thing you can check is to monitor the fan speed either visually or by sound, the speed should increase as the CPU load increases.

There is also a utility that also monitior you fan speed: http://download.cnet.com/SpeedFan/3000-2094_4-10067444.html

"However, what you meant in idle without doing anything. If so, then my computer will be in a sleep mode."

By idle I mean you are not running any programs, just watching screen and the core temperature to see if it drops or increases with the Windows doing nothing but displaying the desktop.

Intel processors have an internal temperature sensor and if the temperature reaches or exceeds a certain value it throttles back / down the speed, which may be what is causing some of the slow responses or stops responding.

As for replacements parts I do not know of any place were you can purchase them in Yemen. I suggestion is that you send an email to HP's US or World wide support site, they may know of a place near you.

Buying an old fan may help if you have some means of testing before you buy it or get your money back if the fan doesn't work.

Your CPU temperatures are way to hot !  Normal at idle should be 40C or less and under load about 60 to 70C.

Thanks a lot,

You mean my CPU temperatures are very excessive, and I must replace the cooling fan as quickly as possible.  I agree with you since my laptop is so slowly responding that I could hardly post this message to you.

Although I have performed a hard reset, these problems below are still:::

Software Freezes, Keyboard stops responding, external device stops responding

However, what you meant in idle without doing anything. If so, then my computer will be in a sleep mode.

Anyway, how could you help me to find a new fan and battery since the HP agent in Yemen doesn't sell the spare parts I need? Do you think that buying old cooling fan, battery will be helpful for me since I am in a very urgent need to replace these components.

    Now, I want to open the back of my laptop, although it does not do it justice. It is major surgery and I mostly come in from the top. I want to only thoroughly clean out the fan or even replace it with a new one since if cleaning it didn't help, then I would need to open the back again, and replace it.

    I need way to get a new fan, and battery. How to do? COULD YOU HELP ME?

First install Core Temp to see what the real CPU temperatures are for each core and post back the reading when the computer is idle and when under heavy use.

Core Temp:

Monitor the temperature of each core of your processor.
