Make the call.
If you forgot to backup, I'd pull the drive out into some USB case so you can copy your files out before sending it in. HP always restores to the factory load so it's up to you to save the files.
I closed the lid of my HP DV6-1264ca (artists edition 2) laptop to put it to sleep. I return back 20 minutes later to open the lid, but it won't start. It does wake up and fans are running and even the LEDs are lit on the keyboard, but the screen is black. I wait many minutes until I force shut it down. I start it up, and the same deal occurs. I notice that the lights beside the caps lock and num lock keys are blinking slowly. Nothing on screen ever appears. What could cause such a sudden problem? It was working fine few minutes ago.
I've tried all solutions that I found on the internet; Unplugging power cord and removing battery for few minutes. I've tried that power reset method (unplug power & remove battery, hold power button for a minute, plug the power cord in, then try booting it) but no luck. I've tried switching up the RAM slots, and removing the HDD. I've even tried removing the CMOS battery for a few minutes. I've tried these solutions numerous times but no luck.
System information is as follows:
Windows 7 64-Bit
Radeon HD 4650
AMD dual core 2.2GHz
Any help is appreciated, thanks.
