Hello,
My laptop is suffering from the same critical problem described very well in https://h30434.www3.hp.com/t5/Gaming-Notebooks/High-CPU-Usage-System-ACPI-sys-GPE-L6F-Storm-Omen-15-..., where the system-process uses up 100 % of CPU 2 and 50 % of CPU 0 time (while the computer is idle).
The process always starts a few minutes after booting the system, and nothing has helped. I have updated the BIOS to Q70 Ver. 01.08.01. Others have found that this issue seems to be in the firmware and only HP can fix it. I am creating a new thread to let HP know there are more of us affected, because it is not possible to reply to the one I linked.
Please HP, can you let us know if you are looking into this issue and when can we expect a solution? Frankly I think it is unacceptable that high-end laptops would have to suffer from such critical firmware issues for long periods of time. Thank you.

I recently updated the BIOS to Q70 Ver. 01.09.01. No change, and no news from HP. The computer is still being drained of battery, computing power, and life expectancy by the constant system interrupts from ACPI.sys. Also due to the high processor usage the cooling fan is constantly on.
All I can say is the customer support from HP has been nothing short of amazing and I have to thank HP for acknowledging this critical issue and providing a fix without delay.
