Upgrade to Windows 7... battery drain

[Jshakour]

I upgraded from Vista to 7.

When I was running Vista I got almost 4 hours of battery life, I upgraded to Windows 7 and now I get less than 2 hours. Has anybody else experienced this?

Go into Power Manager and choose the 'maximum battery life' power plan.

I co-worker of mine did the up grade as well and his battery life is still 4+ hours, should those changes carry over from Vista?

I know on a fresh install of Windows 7, the default is no power plan selected in Power Manager. I can't comment on an upgrade never having done one. It's easy enough to check...

Has anyone received their OEM Win 7 upgrade disks for a W500 yet?

I set the power plan to max battery and it only gave me 12 more minutes, bringing my total to 2hours and 12 minutes. Could it be coincidence that around the time I upgraded I noticed the battery isn't holding a charge?

I used a MSDN Windows 7 upgrade disc.

Sounds like a setting is not right or you got something running in the back ground. Are you noticing alot of HD activity? Most new systems take a while to "settle down" before thing get back to normal

@@UPDATE@@

I had a brand new W500 come in, so I installed a fresh copy of Windows 7 battery was 88% and I was getting 3 hours. I installed the ThinkVantage drivers from System Update, installed the Power Manager drivers and battey life dropped to 2 hours and 19 minutes. I uninstalled the power managment drive and battery life went up to 3 hours and 35 minutes......Interesting!
