[ltp] Poor Battery life of T40 (2379-D5U)

[Binary Xerroz]

i recently bought a Thiinkpad T40 as my first laptop; and all in all im very 
happy with it. i can do all my developing on it  and i can even play ET for 
the most part; however, one thing i am dissatisfied, is the battery life the 
the T40 compared to windows. at full charge windows will give me nearly 5 
good hours, however, linux, has a hard time giving me 3! ive done everything 
i can think of; cpu is throttled to 600mhz, hard disk is on standby, cdrom 
on standby, etc etc. the only thing really working is the fan (which never 
seems to want to turn off) and the wifi  card. but even in windows i have 
the wifi card going so i know that cant be eating nearly 2 hours of battery. 
a friend of mine has a T40, a slightly older model and he claims nearly 5 
hours on linux. so i have no idea why im getting such poor results from 
linux, i recently just sent the unit back  due to overheating problem and 
they replaced teh mobo and said battery needed replacing, so i got a brand 
new one, and i got 30 mins more (to make the 3hours max). I just ordered a 
9cell battery and an ultrabay battery to help but i would really like to be 
able to get something near the windows battery life. any suggestions? Thank 
you.
