Thinkpads Forum

After doing many software tweaks, and playing with the power settings, I find that I can only get around 8 hours of battery life on my X61s, using windows XP, UL screen, 2 gigs of ram, 80 gig hdd.

Are there any hardware tweaks available, like underclocking the processor. It currently has the L7500, so it is relatively low voltage.


I'm just trying to stretch it to 12 hours while typing in word and using the internet. I see no reason really why the X60 has better battery life than the X61s other than the fact that the the new Santa Rosa platform may consume more power.


Any suggestions would be great.


Thank you

You'll need to specify which batteries you're using and what power mode you're using (if you're using the Lenovo Thinkpad Power manager application).

For instance, my X61s uses the 4-cell Enhanced battery and a power scheme called "Ultra powersave" that saves more current than the "Maximum battery" standard scheme. I get around 4 hours. I assume this will double once my 4-cell Enhanced battery arrives.

If you're using the "Extended life" battery that clips to the docking port on the bottom of the X61s, you will get about 2 hours out of that. It's about as expensive as an 8-cell, so I prefer to just have another 8-cell than the "Extended life" battery.
