EliteBook X G1a bios issue

[SBATL]

So I have a brand new laptop (1 month old) and now after being forced to upgrade the bios and some Microsoft updates I can not longer boot.

I am getting either:

- Stop Code: SYNTHETIC_WATCHDOG_TIMEOUT error. 

- It just freezes on the bios startup and the spinning circle just freeze's.

I have tried holding down the power button for 10 seconds, and 30 seconds (unplugged and plugged in) ....
Is anyone else having issues?

@SBATL, Welcome to the HP Support Community. 

Thanks for reaching out about your query regarding the HP EliteBook X G1a. 

We're thrilled to have the opportunity to assist you and provide a solution. We hope our assistance has been helpful! 

I'm sorry to hear that you're experiencing boot issues with your HP EliteBook X G1a after a BIOS and Windows update. Here are some steps you can try to resolve the issue:

1. Perform a Hard Reset:

   • Disconnect all external devices.
   • Unplug the power adapter from the laptop.
   • Press and hold the power button for about 15 seconds to drain remaining power.
   • Reconnect the power adapter and try to power on the laptop.

2. Access BIOS:

   • Restart the laptop and press Esc repeatedly until the Startup Menu appears.
   • Press F10 to enter the BIOS Setup Utility.
   • Ensure that the boot order is set correctly, with your main storage drive set as the primary boot device.
   • Save changes and exit the BIOS setup.

3. Use HP Hardware Diagnostics:

   • Restart the computer and press Esc repeatedly.
   • Select F2 to open the HP PC Hardware Diagnostics.
   • Run a full system diagnostic to determine if there are any hardware issues.

4. Perform a System Restore:

   • If you can access the boot menu, select Troubleshoot and then Advanced options.
   • Choose System Restore and follow the instructions to restore the system to a previous working state.

5. BIOS Recovery:

   • If booting into the BIOS isn't possible, HP notebooks often have a BIOS recovery feature.
   • Turn off the laptop completely.
   • Press and hold the Windows key + B key together, then press and hold the Power button for 2-3 seconds, and release the Power button but continue to hold the Windows + B keys.
   • You should hear a beep, followed by a BIOS recovery screen if the BIOS recovery is initiated successfully.

I hope this helps!

Take care and have an amazing day!

Have same issue.  I was working in Windows 11 on a one-day-old EBXG1a laptop when suddenly got an involuntary pop-up message that the BIOS had been updated and required a reboot.  This was unprovoked; am uncertain how it updated.  Regardless, upon rebooting, the EBXG1a flashed the bios (9 stages) after which it rebooted and the spinning indicator consistently froze.  I was required to download the previous (June 2025) BIOS version from the HP Support website, write it to a FAT32 thumbdrive and downgrade.  Fortunately that resolved the issue.

1.) what app or BIOS setting is enabled that requests these unwanted updated and how do you stop them?

2.) why is HP pushing out a current BIOS version that renders the Elitebook X G1a unusable?  This is a massive problem that needs to be addressed.

They had to send a tech out with a new motherboard and SSD. 

I am assuming the board was a newer revision possibly.

Oddly I've received the newest hardware revision directly from HP and yet the latest available BIOS version rendered my system un-bootable.  Fortunately, I was able to rollback to the previous BIOS version and rectify the issue.  Now, I'm looking for whatever system option was enable that prompted my laptop to take the liberty of downloading AND installing the latest BIOS without giving me the option of approving it.  Scary.

Since it's a laptop with Wolf installed, is it HP Support Assistant that does this?  Or is there a BIOS option that can be enabled/disabled to turn that "feature" off?
