I'm having this exact same issue except I upgraded from vista business x64 to windows 7 professional x64.  I've lost an hour of battery life.

I'm having the same issue.


I'm very disappointed in my tablet and contemplating ditching Windows 7 until SP1 or this gets resolved.  I've gone from 9 hours to 6.5 hours under the same usage, and this is after disabling a number of services, themes, unused hardware (modem, webcam), customizing power settings in Windows and Power Manager ... ... yeah.

Re: Win 7 x64 vs. Vista x64 - battery lifetime

BTW, I recognized that all my context list flicker when opened for the first time.

Using Firefox 3.5 I saw such a behaviour also at my RSS feed lists.

 

Is it possible that switchable graphics driver is not working well, which in the end leeds to a higher power consumption?

 

Is it possible to use ATI and INTEL original graphic drivers instead of switchable driver from lenovo?

Same problem here... I had 3,5-4h of battery life (Energy Star) and now it's decreased to 1,5h ... wtf?

 

I upgraded the Energy Manager after the OS Upgrade from Vista to Seven. But still no difference.

 

Please help, cause I need at least 2,5h-3h battery life for my daily "mobile" work :smileysad:((

 

thx

Re: Win 7 x64 vs. Vista x64 - battery lifetime

Can everyone do the following please.

 

Start > CMD (Right-Click Open as Administrator) > Type "Powercfg -energy"

 

It'll generate a html file that will specify what your laptop is doing during battery mode.  Remember to set your power setting to "Maximum Battery Life" before running it.  If it gives you any errors post them here and stat your laptop model.  Let's get more information and band together to find out specific issues.  I posted my results on the first page.

Re: Win 7 x64 vs. Vista x64 - battery lifetimGood Idea

Good idea, I just did that. My TP is an X200s (7469-A28) running Win7 x64 with 3GB of RAM and an Intel X25-M G1.

 

I have several Errors in that report. My system is German. There are 3 errors, the first 2 being USB devices not entering standby, the 3rd error is the PCI Express-ASPM, as posted before. Here we go:

Hopefully Lenovo takes care of this issue or even escalates it to Microsoft. I lost roughly 33% battery life with my move from WinXP 32bit to Win7 64bit. That is simply unacceptable, especially because Microsoft stated that power management in Win7 has been improved compared to its predecessors.

Looks like it might be an issue with Win7 x64?

I ran the energy check and it found 2 errors:
