    I have a Compaq Presario 2700T with problems. When I press the start switch it runs for about five seconds and then shuts off. It doesn't even run long enough to give me any screen image. It does this on every attempt to start the computer now. Prior to that it flashed a blue screen on a previous start attempt but not long enough to read what it said.
    Any ideas what is going on?

    Does this happen when the power connector is attached?

    Are there any lights on when the power connector is attached? For example, does the battery charge?

    Do not be rough with the cable, but the power plug that connects to the laptop, does it make any difference if you gently bend the cable around or move the connector in the socket? (Occasionally over time either the cable becomes damaged or the socket becomes loose)

    Some other things that could be wrong. The power circuitry could need to be reset, the batttery may have gone bad, or the DC adapter may be bad.

    If you have a voltmeter or test light you can check the DC plug to be sure you are getting voltage there.


    Disconnect the DC cord from the computer and remove the battery.
    Hold the power buton down for about 20 seconds.
    Reconnect the DC cord, but don't install the battery, and turn the computer on.
    The computer should run without the battery.
    If the computer doesn't work, then there is no power at the DC plug, the DC socket on the motherboard has been damaged, or something has burned out in the power circuit.

    If the computer runs without the battery, turn it off.
    Reinstall the battery and turn the computer on.
    If the computer doesn't start, then the battery is probably bad. Could also be a problem in the power circuits.
