Poor battery life on 5320?

I just received my NP5320. Beautiful screen (WUXGA), fast doing digital imaging (2.13Ghz Pentium M, 2GB RAM), but crap for battery life. I suppose I should be grateful -- the 3880 it's replacing manages only 15 minutes at this point and only achived 50-minute when new. The 5320 managed 2-hours only for strickly internet surfing. Makes me think a 2-hour DVD will die before it's finished.

An Acer Ferrari I tried got over 3-hours while surfing, and easily finished a 2-hour movie. The complaint with that computer was that the screen didn't have the quality for digital imaging, and the volume was too low to be heard (through a headset) on a plane.

Is this about the best that can be expected from the 5320?

My advice to you then is to pick up the Secondary Bay Battery for the 5320. I have it and it extends the battery life quite significantly. I can web surf on it for over 3 and a half hours and do some hardcore gaming for over 2 hours with it. Its a 6 cell battery that goes into the DVD slot, so you will loose your DVD, but for other things its totally worth it. Kicks your computers battery size up to 14 cells.

I should add that i have also undervolted my processor which added on average about a half an hour to the battery life of this baby, so in lew of buying a new battery, undervolting is a great alternative.

*EDIT* I should also add that mine is configured with a 2.13ghz and 2gb of ram as well, except i have the WSXGA+ screen.

Poor battery life. . .

Thanks for the reply. Unfortunately, when I'm traveling, I usually need the DVD for backing up a day's shoot, so the second battery isn't the answer. I'm also trying to kep my briefcase/backback as light as possible. (I loved the brief use of the Acer Ferrari -- what a difference even 1.5 pounds make.)

How do you "undervolt" the processor? How do you know what the correct setting would be so you don't cause damage? I suppose that's one solution when I don't need the raw number crunching of digital imaging.

Battery life on this thing isnt so great. But I thought a 2.13ghz processor would get better battery life than that. What a difference a few MHz can make.

Secondly, undervolting your processor depends on the processor itself. Every one is different. You'll have to expariment to find a good setting. Theres a good tutorial in the notebook guides section at the top of this forum. Also, undervolting will NOT hurt your systems overall performance. It doesnt underclock your processor it just lowers the voltage flowing into it. You'll still run at 2.13ghz with all the processing ability that comes with it.
