PAVILION 15-EH1052WM bricked durring bios update

[DUCATI9S]

I upgraded from windows 10 to 11 then came all of the updates once windows 11 was finished installing. One of them was a BIOS update. I restarted my PC and it froze on the BIOS update screen for an hour and a half. I couldn't restart or shut it down. I unplugged the ac adapter and disconnected the battery. Now it's bricked. Just the power light when I turn it on. Black screen.I've tried the win key + B, win key + V, holding the power button down for 30 sec with the battery and ac adapter removed, bootable usb and connecting it to an external monitor. Still black screen. I really need some help! Thank you in advance

Hi @DUCATI9S 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thank you for sharing what happened, and I’m truly sorry your Pavilion 15-eh1052wm is unresponsive after the BIOS update. It’s deeply frustrating when a routine update leads to a black screen and no signs of recovery, especially after trying every known shortcut and tool.

Let’s walk through a few focused steps that may help restore functionality:

 

1. Attempt BIOS Crisis Recovery (UEFI Rollback)

Even if the screen is blank, this may trigger a hidden recovery:

• Insert a USB drive with the correct BIOS .bin file from HP’s support page:
  HP Pavilion 15-eh1000 BIOS & Drivers
• Press and hold Windows + B, then press and hold the power button for 2–3 seconds.
• Release all keys and wait up to 60 seconds.
• Listen for beeps or fan movement—this may indicate BIOS recovery is initializing.

If you’re unsure which BIOS file to use, download the latest version for your exact model and extract the .bin file to the root of a FAT32-formatted USB drive.

 

2. Try External Display Again

• Connect to an HDMI monitor or TV.
• Power on and press F4 repeatedly.
• If the external screen shows output, the internal panel may be disabled or the BIOS is partially functional.

 

3. Remove SSD and RAM Modules

• Power off and remove the SSD and RAM (if accessible).
• Reinsert one RAM module and power on.
• This may trigger a minimal boot state and force BIOS recovery.

 

4. Reset CMOS (If Accessible)

• If your model allows access to the CMOS battery, disconnect it briefly to reset firmware settings.
• This may restore BIOS visibility.

 

5. Service-Level Recovery

If none of the above steps restore functionality:

• The BIOS flash may have failed mid-write, corrupting the boot block.
• This typically requires a firmware reflash using an SPI programmer or replacement of the system board.

You’ve clearly done everything right, and your persistence deserves resolution. Let’s work together to bring your system back to life.
