HP Pavilion Entertainment PC Laptop approximately 2009 boot black screen and cannot enter bios mode

[Pgreenaway23]

HP Pavilion Entertainment PC laptop circa 2009 failEd to boot, black screen, or enter bios mode.

Tried resetting with battery in n out. Reseeded 2 memory cards, HDMI cabled to TV set, hitting ESC key during power up as well as F10 and Windows key with the B key.  All had no effect. 
LEDs over Scroll key on top and Caps lock key flashing white colored led.

DVD draw still opens.  Speaker muted dumbo lit. 

I am at my wits end.  Any ideas or help?

Most likely, the PC is experiencing a major hardware failure -- this is especially true if the CapsLock key is blinking or there is beeping.

Since the PC is a laptop, this HP thread describes the different blink and beep codes: https://support.hp.com/us-en/document/c01732674?jumpid=reg_r1002_usen_c-001_title_r0001

--------------------
If you CAN, to find out the problem, you would need to run hardware diagnostics by pressing the Esc key repeatedly and then, when the HP Startup Menu appears, select Diagnostics (usually F2) and let it run.

If you can NOT do that, 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.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.

Since your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.
