Hi, I've just run powertop for the first time and this is what I've got:

Quote:

Top causes for wakeups:
30.1% (460.0) VirtualBox
22.3% (340.5) swapper/0
9.1% (139.4) swapper/1
8.3% (127.3) opera
7.6% (116.8) [extra timer interrupt]
6.7% (101.7) opera:libflashp
3.3% ( 50.2) [iwlwifi] <interrupt>
3.1% ( 46.9) [snd_hda_intel] <interrupt>
2.4% ( 37.1) [Rescheduling interrupts] <kernel IPI>
1.6% ( 24.8) [ahci] <interrupt>
1.3% ( 19.9) xfsaild/dm-1
1.3% ( 19.9) xfsaild/dm-2
1.3% ( 19.9) xfsaild/dm-5
0.3% ( 4.0) VBoxSVC
0.3% ( 3.9) audacious
0.2% ( 3.2) xchat
0.2% ( 2.8) soffice.bin
0.1% ( 1.1) liferea
0.1% ( 1.1) conky


Okay, I know VirtualBox is a great power consumer, but why is swapper waking up so frequently? I'm also worried about "[extra timer interrupt]" - what is this.

Any ideas or thoughts are welcome.

Thanks
