[ltp] r50 battery problem

[Chris]

hi all:

after two weeks of using wireless connection on my network, i recently found 
out that my battery life has on average reduced by almost one hour. i used to 
get a round about 4.5 hours after fully charged, but right now it only 
displays 3 hours 40 min or so after it beeps saying battery is fully charged. 
I only got my laptop for 2 months, it's R50 1829 6DM, does anyone have a clue 
what went wrong? or the wireless has absolutely nothing to do with the 
battery life? 

I used to use acpi, however it's not quite working out on my laptop as some 
functionality are not functioning at all, so i switched to apm and it works 
pretty well. but i did cat my battery capacity through acpi and it reported 
the last fully charged was actually 90% of the designed capacity, is this 
normal? at the time i check it the laptop has only been used for less than 2 
months.

Thanks

Chris
