HP Pavillion black screen

Dunno if y'all can help. I've posted in the HP support forums too.
My laptop was working fine last night. I was in a hurry to go to sleep so I turned it off via the power button to avoid the "shut down updates". It sat there with a cd and external keyboard plugged in as well as ac (I know I'm aweful). Today I try turning it on, and it boots (light in power button, leds around the ac adaptor, but no lights on keyboard) but the screen is black. Not back lit or anything.
I've tried a hard reset, I've unplugged the keyboard and took the cd out.... Hubby was cleaning today and I'm seriously conserned he broke my screen. Is this fixable?Oh, as a side note (and to make me feel better about the possibility of it not being broken) when it boots with the keyboard plugged in there are no lights on the keyboard to show its even plugged (it usually has numlock's light on). And I have a fingerprint reader; that doesn't flash either (like it does on my login screen when the reader is on.)

I saw some people suggesting pressing power and ESC at the same time... unfortunitly i had spilled a bit of coke on my keyboard months back and half my keys dont work (thus the external keyboard until I amazon-buy a replacement). I don't rememeber if ESC was functioning on the original laptop....

I guess no one is able to help....?

Hi Mekito. Remove the power cord and take the battery out. Hold the power button down for 30 seconds. Leave the battery out and plug the power cord in and try and boot. Post your results.

Nothing happened or changed. The hard reset was the first thing I tried...

I've also tried hooking it up to an external TV monitor via HDMI cable. Nothing. Tv didnt even register it was plugged in. Gonna try a actual monitor cable tomorrow.
