    This especially important with laptops, make sure that none of the cooling ports are blocked.

    This will obviously cause the cooled area to overheat. The fan can also burn out.

    Almost any symptom on your machine can be a sign of a power supply failure. It could be weird hard drive symptoms, it could be your CD ROM drives not working correctly, it could be all sorts of RAM restarts, or it could be cue errors.

  • Question
    How long does the BIOS battery last and can it prevent the PC from powering up?
    Community Answer
    Usually they will last for 5 years or more; they save the settings for the BIOS and the clock. As to whether they will cause the computer to not power up, that's based on the design. Usually it just causes you to lose all of your settings if you disconnect the computer from AC power, but it could also cause the computer to not boot up if your BIOS is completely dependent on it.
