I recently noticed that my tablet battery runs down faster at work than 
at home, with the WiFi enabled but otherwise sitting idle (12%/hour vs 
1%/hour).

I thought the issue might be that there's more broadcast/multicast 
traffic at work, which would get through the filters in the ethernet chip 
and into the kernel, but then I found a reference to your post on the 
list.

At home I have a Linksys WRT54; at work I think Orinoco-AP2000 where I 
may be able to change some settings (writing this at home I can't login 
to check).

What power-management issues have you seen affecting battery life ?
Would it affect other laptops as well or just the tablets ?
