Lenovo Legion 5 15ITH6H – “Device Freeze” screen (possible Absolute/Computrace) – ca

[Fèlip3]

Hello everyone,
I’m fairly new to BIOS/firmware topics and I’m facing an issue with my Lenovo Legion 5 15ITH6H laptop.
Device details:

• Model: Legion 5 15ITH6H
  
• S/N: PE09EVFP
  

Issue:
The laptop was working normally, but after being powered off for a long period, it started showing a white screen with the message “Device Freeze”, without much additional information.
After discussing with some friends, one hypothesis is that this might be related to Absolute/Computrace (possibly triggered after long inactivity or some kind of remote lock).
Questions:

1. Is this “Device Freeze” screen typically related to Absolute/Computrace on this model?
   
2. Is it possible to resolve this by reflashing the BIOS and/or EC?
   
3. If yes, which dumps/files would be needed (BIOS dump, EC dump, serial, UUID, etc.)?
   
4. Is there any significant risk of bricking the motherboard during this procedure?
   

If anyone has experience with this model or this specific issue, I’d really appreciate guidance on the safest way to proceed.
Thank you in advance.

Update:

I was able to obtain the dumps from the laptop.

I have attached a ZIP archive containing the following files:

full dump (24 MB)

BIOS region (16 MB)

MB/EC dump (8 MB)

All files were read directly from the device and packaged together for analysis.

Please let me know if any additional dumps or formats are required.
