When I opened the laptop out of sleep mode, it froze on the lock screen. When I powered it off and turned it back on, it booted to a blank screen. Now, it will only boot to a blank screen. I press the power button, the computer turns on, the power light goes on, and the computer goes to a blank screen. The keyboard seems to work (when I press the Caps Lock key, the light goes on), but the computer stays on the blank screen. Nothing has worked. Here is what I have tried:
I tried connecting the computer to an external display. No joy.
I tried to access the setup, diagnostic, and BIOS menus. I pressed Esc, or F10, or F2, or F12 until my fingers bled. I have fast boot, so I have pressed each of these keys before hitting the power button and then spamming the keys for a good 5-10 seconds after the blank screen appears. I tried fn + F10, 12, 2, etc. Combinations, (Esc + F10) but nothing. The menus don't come up.
I tried Win + B. Didn't work.
I tried Win + V. It worked. I got the following message:
"The CMOS checksum is invalid. The CMOS will be reset to the default configuration and will be rebooted. Please check your BIOS Setup options to see if they change.
CMOS Reset (502)
ENTER - Reboot the system"
If I press Enter, it shuts off and restarts to a blank screen. After 15 seconds, same thing. Restarts to a blank screen.
I have tried A BIOS recovery through downloading the previous BIOS version from the HP website onto a USB. I followed the instructions for the Spectre and tried to recover through the USB. Nothing. BIOS recovery/update screen never comes up. Just the blank screen.
Help?
