A one-line patch to the HP WMI x86 platform driver for Linux was posted for allowing the HP OMEN Transcend Gaming Laptop 14-fb1xxx to correctly hit its rated TDP limit for allowing better performance outside of the Microsoft Windows confines.
The HP OMEN Transcend Gaming Laptop 14-fb1xxx is a ~$1300 laptop powered by the Intel Core Ultra 7 series and with a 3K OLED display, NVIDIA GeForce RTX Blackwell discrete graphics, and other high-end features.
The HP WMI driver on Linux needs the HP OMEN Transcend 14-fb1xxx gaming laptop’s board ID added of “8E41” so it will use the proper thermal profile. In doing so, Linux then matches the 65 Watt TDP of the CPU under Windows rather than being limited to 45 Watts. This also allows for the maximum fan speed to be activated for sufficient cooling.
The patch explains:
“Reverse engineering of the HP Omen Windows utility shows that for performance mode it uses the same codes listed in hp_thermal_profile_omen_v1. Therefore it seems sufficient to add the board model name to omen_thermal_profile_boards.
Tested on Omen 14-fb1xxx: CPU power in performance profile reaches the Windows limit (65W), instead of 45W in automatic BIOS mode. Max fan speed was reached as well.”
The patch is out for review on the mailing list and given it’s just adding the board ID to a list, it should be safe for picking up pretty quickly by the mainline Linux kernel as a fix.
