hello, im looking to update my vbios to get better battery life on my battery... i looked at the gary key one, but it seems kinda old. i heard that chastity's is good. i've never got GSOD, and im looking for the best vbios for battery life when im using my laptop on battery. i dont know what Chastity's Overdrive is.. and i think it is overclocking.
can someone link me to the newest and best vbios for battery life on Battery that works..
thanks.
and can you give me instructions on how to flash vbios.

thanks
