Acer Aspire 5738G powersave

I have Archlinux installed on this laptop and most of the tings work just fine but my battery is getting discharged very quick ~1hour - 1h:30m. A frind of mine has exactly the same laptop but using Ubuntu and when he is on battery it discherges for 3 hours !? That is very big difference. Here the output of cpufreq-info

  current policy: frequency should be within 1.20 GHz and 2.20 GHz.
                  The governor "conservative" may decide which speed to use
                  within this range.
  current CPU frequency is 1.20 GHz (asserted by call to hardware).

My fan is almost all the time on max speed and i think this is cousing the problem. Any suggestions.
