I am very confused. My compaq laptop won't charge or turn on at all. I don't know whether it is the charger or not, but it won't turn on. I am quite worried, as this was an expensive laptop. The warranty has also expired, so the company won't help me. It did finally turn on a few months ago, and stayed on for a couple of hours. Then stopped working again. Help me please?
It might be a bad battery, or a bad A/C adaptor.
Remove the battery and any external devices like a docking station, external cd/dvd drive, harddrive, keyboard, mouse. etc.
Connect only the A/C adaptor to the laptopand to the wall outlet.
See if it powers-on the laptop now.
