    My husband Bill has a Gateway PC that runs Windows 10.
    Model NV77H18U

    When he presses the switch to turn on the computer, blue light located in switch blinks 5 times and computer doesn't turn on.

    He got it to start up once by plugging directly into outlet, instead of power strip, but now it's not starting at all either way.

    He just tried again, and it seems to be working but it may not for long, as this is what happened yesterday.

    Can you help?

    Thanks,

    Tricia

    Will try this- thanks!

    1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
    2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
    3. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
    4. The motherboard could be defective & needs to be replaced.
