Battery Life with the X61T Tablet PC and Vista

- Rob Bushway

Battery life has been really good with the Lenovo X61T Tablet PC I've been using. I'm getting about 6 hours with WiFi on with an 8 cell battery.

To get that, I set my power plan to Power Saver. Then, I modified the Power Saver Advanced Settings to have better performance when plugged in: set the processor to a min of 75%, max of 100%. I also adjusted the screen brightness for plugged in value, too. Screen brightness on Power Saver under battery is set to 40%. I've also got the Sidebar and Aero turned off. Using the standard Thinkpad Default power settings, I was getting between 3 and 4 hours. That's pretty good battery life if I say so myself!

I'll play with that a bit and see - will be next week before I get to that, though. I suspect, I'd see the battery drop to about 4.5 - 5 hours.

Rob, I wanted to set my power plan as you have written and as I have not played with the power plans so far on my X60 I wanted to know where are you setting up this min and max processor etc. - in my Power Manager I have

4 default power plans - max battery life, timers off, maximum performance and power source optimized - I cannot set anything in percanteges just choose from 1 to 7 boxes of performance, fan noise etc...

any suggestions?

I'm doing it in the Windows power options. Left click the battery, then choose More Power Options. Select Power Saver, then choose Change Plan Settings, Changed Advanced Power Settings.

Scroll down to processor power management, set Min for plugged in to 100%, Max for plugged in to 100%

try that and let me know if you have trouble

I have to have my screen up full and can't afford to compromise my CPU. The real question is what were you doing during those 6 hours? Casual surfing, listening to music, running queries, printing etc.

Browsing, posting articles, reading email in Outlook, running Word.

With full brightness and cpu set at 100% on battery, one can expect decreased battery life for sure - no doubt about it. For me, though, I find the compromises acceptable. The good thing about starting off in Power Saver mode as your beginning point, adjustments can be made upward in terms of brightness, cpu, etc in order to bring the system back up to an acceptable level. It is harder to do that going from top performance on down.
