hp envy 17 j130eb problems after updating bios

[MDev]

Hello,

So today i planned some maintenance on my laptop, everything went well until the last bios updated finished and restarted my PC.

Now my PC won't boot anymore at all. I have a total black screen with no flashing or anything.

I can't acces any parts of the bios.

I have already tried to resolve my problem by:

- Commiting a hard reset without any success.

- Attempting to recover the BIOS by holding Win key + B and startup key for about 3 sec than released while still holding win key + b for like 2 minutes with no success.

- I unplugged the CMOS battery and replugged it without success.

- I unplugged and replugged my hard drives (at both ends) with no success.

- I also tried to unplug and replug both my ram cards but still with no success.

- I re-downloaded the oldest bios software from the HP website for my laptop and followed the steps:

1: Install bios image to USB flash media

2: Finish installation and remove USB.

3: Plug USB into faulty PC

4: Hold Win key + b while pressing power button for 3 seconds and released power button while still holding win key + b

Also these steps didn't work out for me.

The screen keeps black and the shift button light is blinking continiously at a rate of 2 blinks each loop.

And ofcourse i have followed all the above steps the right way, so i unplugged all power when i had to alter hardware.

Also important to note is that none of the function keys are functional upon startup (F2, F8, F9, F10,...) just a black screen not even the leds of the screen are lit up..

Thanks you.

Can anybody please help me?
