Timeline 4810TG Windows 7 battery issues

0wn3d · 11-07-2009, 06:10 AM

Hi,

I did a clean install of Windows 7 ultimate 64bit a few days ago.
All is fine except one major issue; My battery capacity dropped to half of that in Vista. I am now lucky to get over 3.5 hours. In Vista I had an average of 6-7 hours.

What could be the cause of this? I have updated all drivers and empowering software. I also installed the Vista version of the Optical Drive Power Management just to see if that was the cause. No luck

Anyone else experiencing poor battery times in W7? Is 64bit known for reducing battery times?

I have the Aspire Timeline 1810tz which came pre-loaded with Windows 7 64bit Home Premium and I get about 6.5 hours web browsing with wifi so the problem is not Windows 7.

Did you install the drivers from Acer DVD or from the Web?

I downloaded all drivers and ePower software from Acer website. All 64bit versions and from late October.

CPU usage is normal and should not be causing this.

Is there any way to test the battery to find out if it might be damaged?

Thanks for any help.

Run this command, and it will generate an energy report on your C drive. You can then review any settings or errors, etc. that might be causing excessive battery use. It will also report your battery capacity at the last charge.

powercfg.exe -energy -output C:\EnergyReport.html

Hello,

Got the same problem.... Just switched My Timeline 4810 to Windows 7 (32-bit) and it doesn't look like my battery will be as good as before.

Did you manage to fix the problem?

Thanks !

Same problem- I have the 4810T with Windows 7 Ultimate 64 bit. Battery life went from 7+ hours to 4 1/2 to 5 hours.
