Sony Vaio wont charge battery after clean windows 7 install  

Hello all,

I hope someone here can help since i have searched the web far and wide for a solution but nothing seems to work.

Okay so i will tell you what led up to this problem:

I had a friend with an Sony Vaio SVF15A1C5E who from when he bought it had windows 8.1 installed. So he came to me with windows 7 and asked if i could make a clean install with. So i did without any big problems, he had it for like 2 months and everything worked. Then he installed some shitty programs on and it went slow on him. So we had to reinstall windows just to make sure everything was gone.
So i reinstalled Windows 7 without any problems every driver seemed to work but suddenly i noticed that the battery would not charge which i found odd, so i fumbled around with the AC but nothing seemed to work. Then i tried to reinstall the driver for the AC management that was on it. Still nothing seemed to change it. Then i thought okay, i will just reinstall windows 7 once again and it should work. But sure enough it did not work. So i am stuck now and i do not know what to do.

Notice this is a laptop only 1 year old and the battery cannot be taken out so i can try those options people have come up with on other threads. Also i tried to update bios but it says that bios is fully updated. SP1 is also installed.

I really hope someone can help here. Thanks.

Okay so now i have installed windows 8.1 on it and it does charge with it. So it is without a doubt a software problem. im still not having windows 8 on this laptop. since my friend wants windows 7 on it.

Also note that Vaio Control Center only brings up System Information and Display on which i can't change anything.
Tried the last hour different options on how to install this Power Management utility but i have no luck. I really hope there is a way to install it manually. Its an exe file so i can't even extract the files inside it.

Okay so i tried your link, and i got the installer up and everything. But it seemed to want to uninstall power management which indicates that it had been installed when i previous tried the original file. But i uninstalled the driver and tried yours. Restarted but i still get "consider change battery" And it still wont charge. This makes me wonder if it is somewhere else there is a problem?
im running out of options here. But thanks again for the help maxie.

Well since the battery works fine on windows 8.1 when i installed that i doubt it is the battery.
The windows dvd is legit if thats what you are wondering. And since we have installed it once before where it worked fine i am totally lost here.
