NEW 9400 .....battery life??

i just got my inspiron 9400 book ......it claims to hold a 6 cell lithium ion battery ......all over the place i keep reading 53WHr capacity of these batteries......well mine lasted for about 1 hour 20 minutes......during the test i was continuously playing a audio cd ...........now does that qualify as 53WHr .......

 

aah and yes my books config is >>


1.83 core2duo (fsb667 2mb)(tested @ full brightness)
2GB (667 ddr2)
17 " monitor (matt-xga)
(256)9800 go gs
onboard sound...
midline volume.......woofers working @test contineously playing trance for 1hr 20 min......

the power went low .....enuf for an auto shutdown......is this comparable to 53 WHr?

 

what screen brightness, power saving modes,? 53/w per hour doesnt mean 53 hours if that what you were thinking, screen brightness, the apps you are running, drive usage, all drain the battery, playing a cd from the disc dive will tank your battery much much quicker than off the harddrive, the 6 cell is the smaller battery, if you need more time unplugged, get a bigger battery, lower the brightness, use the optical drive only when you have to, and enable power saving modes where possible, cpu/vid card/network card etc. Your battery sounds fine, you just seem to be expecting a bit more than its capeable of

 

all i wanna know is how long is a 6 cell lithium ion battery likely to run on a standard config running only usual wordprocessin applications........i aint too nosy just wanna check if i am not off by like a hour or so in the battery juice duration......

 

what do you consider standard?, max brightness is not standard on battery power, and will drain your battery much quicker than half of 3/4. I dont have your particular machine, so I dont know for certain. I do have a 6 cell battery, but its on a machine with a much smaller screen, and a more battery friendly video card, at a guess I'd say 2 hours with power saving measure in effect, please dont pm general questions in the future
