Laptop battery life?

I just bought a used HP Pavilion n3210 laptop and tested out the battery life on it. To my dissapointment it only lasted for 1 hour and 20 minutes 🙁 This should be a much longer time shouldn't it?? What is a good battery life for a 433 mhz, 256 mb memory, 12.1" screen laptop? Also where is a good place to buy batteries at?

Sorry if this is posted in the wrong forum, let me know where it should be posted if not in here.
 
An hour and twenty minutes isn't horrible. You should go to HP's website and see what the battery life specs are. Plus you can do things like lower the screen brightness and, if available, lower the CPU speed to increase battery life. The computer is two years old. I would expect Toshiba's with those specs to last about that long if they have a passive matrix LCD, and a little longer (1h30m-1h45m) if they had a 12" TFT LCD. You can always purchase another battery for it and then have two batteries, but first I would see how much you run it on battery before you purchase one. HP's website is a good place to start for a battery. You probably could go back to Ebay for batteries too.
 
First question is what kind of battery is it? NIMH or LiIon? NIMH laptop batteries seem to have extremely short lives while LiIon's seem to last forever.

Batteries.com is a good place to get batteries.
 
The one I am using now is a Ni_MH battery, very dissapointed with the life of it. Too bad the liIon batteries cost around $150, buying that would kinda defeat the purpose of me buying a cheap laptop!!!
 
what os r u using? if its non-NT like win98, then u can try run rain.exe or similar program to save some power. usually it give 25% longer battery use by cutting down cpu usage.
 
When you got your H-P lappy, did you calibrate your battery system? Most laptops have some sort of "gas gauge" calibration routine that needs to be run initially and then every month or so. Normal battery life for a NiMH unit is about 2 to 3 years of normal use.

I am on my 5th lappy . . . and batteries keep getting better. The last 3 have given me 3 hours of calibrated runtime.

The calibration run is usually in BIOS/CMOS and it takes you to a full charge . . . then a slow 100% discharge followed by a full recharge. It takes several hours. A good over night project.
