Compaq Presario won't turn on

  1. Hi, i'm having a problem turning on my laptop. I'm using a Compaq Presario C502US. I've been using the AC adapter that came with the laptop but eventually the AC adapter became loose and broke. The charging icon (lightning symbol) wouldn't turn on anymore and I think the laptop has now run out of power. I've finally received a new adapter and when i plug it in the charging icon lights up. However the laptop still won't turn on. I've waited for about 2 hours but it still won't turn on. When i click the power button, the Power turns on and then it blinks. The Fan turns on for about 3 seconds but then it goes off and the power light blinks and the monitor won't turn on. Can anyone help me with this problem?

    Remove battery and power adaptor (ie all power out)

    Hold down the ON button (to disperse all internal power)
    Plug the power adaptor back in only (and to wall socket!)
    Turn on!

    If it works, turn back off, and re-install battery, turn On

    Oh yeah 30 secs

    but failing that, you may also want to re-seat the Ram (one of those underneath covers)
