Laptop doesn't start (blank screen) after BIOS update.

Hi all!

Yesterday I've tried to update BIOS offered by HP Assistant (version F.51)

After that laptop is unable to start normally. Power led is on, I hear that fans work, but screen is blank.

Tried to reset power by take the battery off and recover with Win+B, Win+V pressed during startup - no result.

PS. And now I can't even check the warranty status of my laptop for service because hp.com can't find product by SN/PN.

Dear HP, how this issue can be resolved?

Turn off the computer, and then connect the power cord.
Press and hold the Windows key and the B key at the same time, and then press and hold the power button for 2 to 3 seconds.
Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.
The HP BIOS Update screen displays and the recovery begins automatically. Follow any on-screen prompts to continue the startup to complete the recovery.

If the HP BIOS Update screen does not display, repeat the previous steps but press the Windows key and the V key. If the screen still does not display, your computer might not support the feature or there is a hard drive issue. Continue to the next step to install a BIOS recovery file from the HP website.
If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the button for only 2 to 3 seconds.

I've passed all these steps. Unfortunately, no result.

Make a flash drive with the BIOS I posted.

Thank you. BIOS recovered.

I should have been a bit more attentively looking at PN and links you posted. 🙂
