notebook 15-ay009dx blank screen caps light blinking

[Rudy1130]

When I plugged an HDMI in my laptop the screen when blank. Now the caps lock is blinking and the screen won't turn on. The caps lock is blinking once.

I've tried the following:

Windows + b

Windows + v

B

Shift  + f7 

Took RAM cards out and reseated 

Tried loading bios via USB

Removed Bios battery. 

NOTHING worked. I'm thinking I might have fried the cpu. Can anyone help with this?

To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.
