try this. remove main battery, disconnect power adapter from laptop, hold down the power button for 20 count, re-install main battery, reconnect power adapter & turn on the laptop.
any blinking lights around the keyboard area & any other lights on?
I'm having the same problem but my light over the number pad and the light by the caps lock keeps blinking nonstop. I tried the options stated above but it only worked once. It's black again. Don't know what else to do...I have a lot of work saved that I need to finish...Help please
I have tried all the suggestions and still nothing. The only thing I can suggest is to get a cheap one off eBay and swap the hard drive over so you can access your work then sell your old one as spares to cover cost of replacement. Apparently Hp are beggars for doing this
