powertop -d / lspci -vvv / dmidecode
Laptop HP Pavilion DM1-1150SL
Distribution: Archlinux
After last upgrade package kernel 2.6.31.x to any kernel 2.6.32.*
consumption of power usage dramatic went up, which is killing battery in my
laptop - from 5h on battery to not even 2/3h.
I was testing it using powertop tool. When usually there was about 300 to 1000
wakeups from idle per second,
now, with any 2.6.32.* kernel, there is about 30000 to 40000. Also jump from
16-18Watts then to even 35Watts!
System load seems to be pretty normal, not higer than ~0.10. Tempratures with
kernel 2.6.31.* is about 42C (idle) while 53C with kernel 2.6.32.*.
i have tried this commandline (grub) without success:
idle=nomwait
clocksource=pit
Everything works fine when i downgraded it to kernel26-2.6.31.6.
i have attached a text file with powertop -d, lspci -vvv and dmidecode
thanks.
