BACK STORY: HP Pavilion DV7-3067nr laptop was brought to me for keyboard replacement and standard optimization. Keyboard was replaced without issues. Uninstalled some garbage programs, did a disk cleanup, installed anti-virus, checked for Windows Updates. Over 200 needed. Noticed it froze during about half way through. Couldn't move mouse and CTRL-ALT-DEL didn't yield anything. I waited hours hoping for it to resolve itself. Eventually, against all of my knowledge and instinct, I held down the power button.
SYMPTOMS: Computer turns on, fans work, etc. No boot, no POST, nothing but black on the screen. Caps lock and Num Lock blink twice repeatedly. Everything I've read says that this blink code is a BIOS problem.
TROUBLESHOOTING: I have removed everything (cd tray, ram, hard drive, laptop battery, and CMOS battery) for hours. I tried pressing on the power button for one minute, once with CMOS battery, once without.
Don't know what else to do since I can't enter POST!
Please help with any suggestions or something I have missed!
