So I've been using powertop to try and reduce the power consumption on my laptop as I only seem to get about 3 hours of battery. From reading other threads on here it seems my power consumption and wakeups are strangely high, here's a summary:

The battery reports a discharge rate of 10.2 W

Summary: 651.8 wakeups/second, 0.0 GPU ops/second and 0.0 VFS ops/sec

The things which stand out as odd:

1.31 W 4.0 ms/s 166.7 Interrupt PS/2 Touchpad / Keyboard / Mouse

So more than 10% of my battery is being consumed by my touchpad/keyboard? That doesn't seem right.

548 mW 34.3 ms/s 45.9 Process compiz

5% from Compiz. Is this correct?

376 mW 1.8 ms/s 47.5 Interrupt [51] i915 298 mW 1.4 ms/s 37.7 Timer tick_sched_timer

Another few percent from these things- not quite sure what they are.

For reference I've installed Laptop Mode Tools, Jupiter (on power save), the CPU governor is definitely on powersave and brightness is on minimum.

What else can I do/Any ideas? I've seen other posts on here reporting laptop battery lives of ~8 hours and power consumption of 4W rather than my 10W...

Thanks!
