HP Recommended
Product: Omen 17-an051nd
Operating System: Linux

Recently, I bought my fifth HP laptop. After years of using HP ProBooks, this time I chose the Omen for my video editing.

 

With Kubuntu (which is Ubuntu with the KDE desktop) I noticed that about one minute after login, one of the eight CPU threads of the i7-7700HQ goes up to 90-95% and stays there.

 

The result is that the CPU ups its clock frequency to 3.77GHz, and the fan increases its RPM to get rid of the extra heat.

Normally, the CPU downscales its clock to 800MHz and the fan is only slightly audible.

 

After searching the Internet, I found on an ASRock SkyLake motherboard forum that the following command brings the idle load back to its normal few percent:

# echo disable > /sys/firmware/acpi/interrupts/gpe6F

 

This works exactly the same on the Omen. The load goes back to its normal state after this command, while I don't notice any side affects of disabling this ACPI interrupt.

 

This problem was solved permanently on the ASRocks forum by the release of a new firmware version of the BIOS.

 

On the Omen, I already run the latest, F.15.rev.A.

Is HP aware of this problem and when is a new BIOS firmware scheduled?

Or do you have any other information?

 

Many thanks in advance!
