HP ZBook Ultra 14 G1a randomly reboots

[PR_Green]

We have several of these devices with the AMD AI MAX 935 . I have ensued all drivers are up to date and also downloaded and installed the AMD software and drivers inline with the processor , however, we keep seeing  the OS randomly rebooting .  An example was a page fault error that was caught by one of the employees, "Ntfs.sys" failed. This can change from time to time and the main issue is the random fails and reboots. I went through the following : HP ZBook Ultra 14 G1a BSOD/Reliability? - Page 2 - HP Support Community - 9402236 

as it was similar but have now tried all these steps as possible solutions. Any thoughts or ideas are greatly appreciated.

Hi, We have just purchased 8 of the 128GB Ram AMD RYZEN AI MAX+ PRO 395 w/ Radeon 8060S (3.00 GHz) ZBook Ultra 14 G1a's and 3 of them are having this issue. All installed from the same image.
Have also install a fresh copy of windows and still the same.
It appears to be a power/memory management issue.
We have split the 128GB of ram into 64GB for GPU and 64GB for Processor in bios.
The random restarts mainly happen when the laptop is on battery and left alone for 5-10 mins and the power state changes to idle or prepares to sleep/hibernate.
Has anyone else seen this issue?
It's incredibly frustrating as we use these machines for Architeure in Revit.
Have tried AMD adrenalin drivers, registry hacks etc and still have the same issues....

The "Ntfs.sys failed" error you're seeing is a Blue Screen of Death (BSOD) issue on Windows 11. Ntfs.sys is a core system driver that handles reading/writing to NTFS-formatted drives (the default for Windows). When it "fails," it often points to problems like:

File system corruption on your drive
Bad sectors or failing hard drive/SSD
Outdated or incompatible drivers (especially storage-related)
Conflicting third-party software (e.g., antivirus)
Rarely, faulty RAM or other hardware

Since this is intermittent (happens sometimes, not every boot), it's often fixable without a full reinstall, but we need to troubleshoot step by step.

I've also now had two of these machines with serious issues related to faulty power management. I was told the first one had a faulty motherboard - so I got the retailer to swap it out. Now my new one is doing sudden and hard shutdowns while on AC power using an official HP power supply.

If multiple of us have experienced these kinds of problems with multiple systems despite following all recommended troubleshooting steps, it seems like there is a major issue that requires a response from HP.
