D620 battery life
My spec is not so different from yours. It is T2300, core duo with 1GB RAM, 80GB HD but a Nvidia video card. I am wondering whether perhaps I don't have a 6 cell battery, maybe it is only four. Does anyone know how I can check? Also is it possible that the Nvidia video card is draining the battery more? This laptop is only about 2 months old so there really shouldn't be that much battery wear. It has never been any different to this anyway.

The nvidia NVS 110m definitely uses more power than the intel integrated graphics. You can monitor the power consumption on battery using programs like Notebook Hardware Control (NHC) or Mobilemeter.
My D620 at medium screen brightness, wifi-on and everything set to max power savings uses between 18-19W. I'd guess an intel integrated graphics D620 would pull about 15W with the same settings (maybe someone could verify this?).
Good thing about the D620 is it has extra battery options. I bought the extended 9-cell battery and the modular bay battery off ebay (a lot cheaper), with both of those i get 6-7 hours.
I probably should have added some more detail in my post, to clarify, I have Dell Quickset installed, it doesn't make any difference. I have done a clean install of XP, in fact I have a dual boot with XP and windows 2000 but both have approximately the same two hour battery life maximum. I have NHC installed on the XP partition and it is set up to max battery. Errr... what else? This battery time is while watching a movie from the hard disk with the brightness set to about 75% and the wifi switched off.
I'm starting to think that this poor battery performance MUST be down to the Nvidia card. Can anyone confirm that they are getting the quoted 3-4 hours with an Nvidia card or do you all have the intel onboard or whatever it is?
i also bought a used dell d620 two months back for 290 bucks
but i also had a battery problem.u know how much u can expect from a 6 cell battery
so as an alternative i used the dell secondary modular bay battery which goes in place of the optical drive.....
my old battery which had only 60 % of its total capacity left and the new modular bay battery are working great
my laptop keep running for at least 3 hrs and maximum 5 hrs...the secondary battery is great and cheap too.
another alternative is to buy the 9 cell battery but i didnt liked it coz it makes the laptop look ugly.
