I have a hp laptop dv6-2088 that will not start up. It worked fine last night, but when I went to turn it on this morning it would not start up. When I turn it on, the fan starts up and the power lights come on, also the the volume control and wifi lights, but the screen remains black. Also the caps lock light keeps blinking. I have tried removing the power cord and battery and replacing them, but it doesn't change anything.
if the blink codes are right it would seem you have corrupted bios. i would disconnect all power to the laptop pull the panels off the bottom and look for the system battery and unhook it. i would then try the above again. if that does not work the hook everything back up and contact hp to see what they can do.
