Product: HP Pavilion Laptop 15-eh1075cl
Operating System: Microsoft Windows 10 (64-bit)

When testing this laptop as a portable backup for Solid Works, an interesting issue emerged.

 

When trying to launch Flow simulation with the power supply plugged in, the computer instantly freezes with a black screen 100% of the time. The fan keeps running, and the power light is on, but the laptop does not respond to anything but a Power Off button hold (3+ sec).

 

If the power supply is unplugged, the very same simulation starts fine. If the power supply is plugged back in when the simulation is already running, depending on the phase of the simulation, it will either freeze, or continue fine.

 

After the freeze, a power reset is required to restart it. The same issue occurs both under Windows 10 and Windows 11. 

 

The BIOS is the latest: F.10 Rev.A 12.0 MB Aug 24, 2021.

 

Running Intel-Burn-Test-2.54 is all fine, no freezes in any configuration after an extended time.

 

This feels like an esoteric BIOS/hardware issue, most likely fixable via a BIOS update given that the issue occurs both under Win10 and Win11. It seems that a software program should not really crash the system like that.
