[xubuntu-users] Power Management in 14.10

Hello all,

I have noticed some seeming inefficiency in 14.10 with regard to power 
management and wondered if anyone else had the same problem. I had 
previously installed 14.10 on a laptop and enabled the new power 
management panel applet with it's lovely cylindrical battery indicator 
[sarcasm]. I noticed that the longevity of my laptop (an asus 1225b) 
when running on battery was about 50%down from prior to installing the 
power management applet. I disabled it but the old power manager could 
not be re-enabled (well I could not find how to re-enable it to be honest).

But for another reason, one related to partitioning and backups, I 
recently reformatted and re-organised the disk structure and then 
reinstalled xubuntu in a new, larger partition with more swap available 
etc.... and I did not enable the new power manager post install and find 
that I am back to the same longevity (4hours + from a full charge) as 
prior to that from enabling the "new" power management panel item. My 
thoughts are that there must be either:

a) a bug/problem with the new power management function in 14.10 causing 
a reduction in battery longevity/charge
b) something else

Has anyone else seen this problem?

Not sure I want to investigate further myself but some of the xubuntu 
people reading this list may want to take a look.

Thanks and Happy New Year!
