Hi,

I own a new Zenbook UM431DA notebook. I've detected that if I remove the AC power and leave it on battery more, the speed of the Nvme drive slows down from 1600MBs to 400MBs (reading or writing).

I think that this is a power saving more, but slow the drive speed to a 25% of its capability is too much. How can I solve this issue?

Thanks

I've discovered that if hibernate the notebook and wake up it again, the speed of the Nvme is again 1.5 or 1.6gbps.

Maybe a firmware problem?
