hi guys
i want to know how long the 9 cell battery on W510 ( i7-820QM Processor and 4GB ram ) can last with the minimize performance and minimize the screen brightness ( to be at least watchable ) to get the longest battery life ever ?

actually i compare it with the T410/T510 i know there no comparing phases but the only thing that i am worry about is the battery life , i don't want it to be less than 4 h or 3.5 h , it will be ok for me if i got 5 or 4.5 hours with the minimize performance and brightness if i am far from AC
anybody help please

I don´t have a W510, but according to the tabook a 9-cell battery can provide it with up to 5.1 hours.

There is another interesting thing, 9-cell plus slice battery can give you a total amount of up to 10.5 hours

Hope this helps,

Marin

thank you so much for you reply

but i hope that anybody has W510 give me his experience about the battery life

I just flew from the D.C. to Frankfurt and used my W510 for 4+ hours on the flight. The battery indicator said I had about 1.5 hours left... I bought a spare battery and it looks like I won't need it. The W510's battery seems to last much longer than my 15" T60p.

thanks RonS so much
that is great for me 4 hours and 1.5 H left so great but can you tell what was the brightness level and the performance profile ?

and when you used it on the flight did it get warm on your lab ? is it was annoying ?

Hmm, I'm not getting such good runtime ... 2.5 hours max
I have the 9 cell battery too

I get about 2 and a half hours but that is running in High Performance mode.
