Shut Down Trouble of COMPAQ 8710w Repaired

By on September 14, 2013

The Notebook was shutting down without any order at about 5 minutes from the moment it was turned on; the owner was really surprised with this abnormal behavior.

When the COMPAQ was disarmed, both radiators (the CPU and GPU ones) were very dirty at simple sight as well as the fan (which cooled down both radiators).

First of all, the CPU radiator was extracted from its place, it had a compressed dust, therefore the hot air of the fan could not go out of the Notebook and the CPU was overheating too much. The compressed dust was taken off, and so far that was all.

On the second hand, the GPU radiator was extracted too, the compressed dust was taken off too, and the fan was cleaned. But I want to express an unexpected problem that was saw in the disarming of the GPU radiator, it had 4 screws (with their clips and springs), and 2 of them were broken and then they were not holding the radiator firmly to the GPU and therefore were loosen (I mean with this that GPU was overheating too, much more than normal).

Another task was to extract both broken screws from their places and replace them with some others from another screws of an unless radiator which was stored as a spare part.

Once concluded the task, the main board was cleaned and the Notebook was armed fully. The output voltage of the external DC Power Supply was tested with a Digital Multitester and the value was correct.

When the Notebook was powered on, it started correctly with its Operating System working so fine and the shutting down trouble was eradicated completely.

    Well that was a good guess when cpus start shutting down like that. Good explanation was given. This shows that we must clean up the stuck dust periodically from the radiators of CPU GPU.

      Of course, you are right, if we do not clean (maintenance job) the Notebooks/Netbooks, they can collapse with the time.

      Nice to reply you, Humberto.

    very good article. thanks for sharting. I have a question for you. i have an HP G62 laptop and it is not powering up. when I measured the power adaptor, on the pin it reads 18.50 and on the inside of the socket reads 19.61. the moment I plug it the laptop power socket, the pin voltage goes down all the way down to 1.7 volts. is that normal. still trying to work on this laptop but any help from you will be highly appreciated. thanks

      Hi Mr. Waleed Rishmawi, I have read your opinnion and therefore I suggest the following for you:
      1- Try with a similar (in voltage and polarity) power adaptor.
      2- If the malfunction persistes the Laptop should be disarmed and check if any component is in short circuit.

      Hope you solve your trouble, Humberto N. Rdguez.

    Thanks for the artice! I like it and I aahave also experienced it before. That is why maintenance is important. Once in a year, at least do the service to the machine ( blowing off the dust, etc ).
    For Vic, are all the fans working, despite just cleaning off the dust?
    Regards, Mark.
