If I run on battery, I must wait a while until the remaining capacity or remaining time change, I know that could be very great if real.. but that is very annoying now as I don't know when the percentage will decrease.. For instance, I started using my laptop, the charge was 89%, after 30 minutes of use (with processes that use a lot of cpu) 30 minutes passed the state is still to 89%. This does not happend on 8.1 and not 9.0 both -RELEASE >How-To-Repeat: >Fix: Don't know, what I know is that HP laptop BIOSes usually send to the OS the current battery state each second (or something similar). We noticed this with a NetBSD developer because the kernel was emitting a message about the battery something like each second. >Release-Note: >Audit-Trail: >Unformatted:
