Ryzen 7 5700u / SolidWorks 2021 SP4.1 / Flow simulation start = dark screen / freeze when plugged in

HP Recommended
HP Pavilion Laptop 15-eh1075cl
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.

I guess a way to test is to use a USB-C power supply, via the PD USB-C port. It would seem to go through a different circuits, and might avoid the issue.

Hi@Modeler,

 

Welcome to the HP Support Community!

 

We reviewed your post and I understand that the  Notebook is not Powering ON,

 

Don’t worry, I assure you I will try my best to get this sorted.

 

I recommend you follow the below steps and check if it helps

 

Do you see a light at the place where the charger connects to the laptop? If yes then it indicates that the charger is all fine.

 

I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

  • Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
  • Disconnected AC adapter from the laptop.
  • Press and hold the power button for 15 seconds.
  • Reconnect the battery and plug the AC adapter.

F6 + Power Button

  • CMOS Rest ( combination of windows button and letter 'V' then push the power button ones and release the windows and letter 'V' after 5sec

 

If the laptop does not power on then please continue with the below steps:

  • Disconnect the charger and remove the battery out.
  • Connect only the battery and check if the laptop powers on.
  • Likewise, remove the battery out (if removal battery ) and connect only the charger and check if that helps.

 

Hope this helps! Keep me posted.
