Product: OMEN 16.1 inch Gaming Laptop PC 16-c0000 IDS Base Model
Operating System: Microsoft Windows 11

After upgrading the BIOS to version F.12 of this laptop the power limit of 5800H CPU is locked at 45W under any scenarios even with sufficient power supply and moderate temperature.

1. I've tried resetting the BIOS but it makes no difference;

2. Downgrading the BIOS isn't a thing: version F.12 locked this option as stated in the download page. I've tried USB recovery without success;

3. Windows power plan and the mode in OMEN gaming hub are set to proper values as well.

The same issue happens to other people as well: 暗影精灵7锐龙版3070 f.12bios功耗锁45w - 惠普支持社区 - 1140174 (hp.com)

So I suppose it is an issue in the BIOS itself.

 

Edit: to make it easier to understand, please refer to the following screenshot showing the thermals and powers during a Cinebench R23 run.

It shows that the CPU is not thermal throttled by any means, and it didn't hit the 65W PPT SLOW limit for even one second. Rather, it is limited by the 45W PPT, which shouldn't be a thing in normal cases.
