Reduced battery life after clean install of Windows 7

I have an HP Pavilion DV6 3070CA laptop. My system crashed and I couldn't access the recovery partition so I bought a Windows 7 DVD, installed it and used the product key that came with my laptop to activate it. I downloaded ALL the drivers and everything works fine now except the battery. It dies when I reach 40%! I know theres nothing wrong with the battery because I got the laptop 3 months ago brand new. I can only use it for 1 hour now... then the battery dies. Before the clean install I was able to use it for 3+ hours!

I did some reseach on this and found out that its a problem with Windows. Its been affecting a lot of users.

So, I bought a NEW battery and got down the product recovery discs from HP and installed windows 7 again using the recovery discs. All is good now but after EVERY SINGLE charge cycle my laptop battery wear goes up by 2%! I cant afford to keep buying new batteries. What am I supposed to do?? I'm soo frustrated!

Somebody please help!!!

I installed all the drivers. Still had the battery issue. Then I gave up and got a new battery and the recovery discs for my laptop from HP. I installed windows 7 from the recovery discs and put in the new battery. Battery life was waay better and it didn't shut off at 40% but the more i use it, the more it loses capacity permanantly. After 3 hours of using it, the charge capacity (shown in HP Battery Check) went from 98% to 93%! That is unacceptable! At this rate, my new battery will wear out in about 2 months!

Im pretty sure its a software issue because this didnt happen before the clean install. I tried 3 batteries and a new charger. Still the same. Battery life keeps reducing the more I use it :(

Its definitely a software issue

There you go

What do you mean by special apps? Yes I've tried restoring twice!. Still my battery keeps losing its charge capacity. As far as I know, all the necessary ACPI drivers that the notebook needs come with the recovery software right? There are ACPI drivers in Computer properties but I dont know what to do with them. I just want to get my notebook back to normal. This is really annoying. Just coz I did a clean install, my battery life went from 3 hours to 20 minutes. Now even after 2 new batteries and a factory restore (recovery discs from HP so it has all the required drivers for the notebook to work), its still going on! I'm starting to hate Microsoft! I love the notebook. Just not the OS

Please check the link. Its a HUGE thread. Reading a few posts will makey ou realize that its a problem with Microsoft

Whoa I've never seen that HP link before. I've done everything. Updated the BIOS, got a new battery, installed all the new updates etc. Didn't work. Then I finally decided to order the recovery discs and do a restore. Its still there!!

Is this the screen shot you wanted? Oh and why does it have drivers that came out in 2006? This laptop came out in 2010 with windows 7. You read the whole thread? Awesome! Yeah its definitely a software issue. Thing is, even after doing a full system restore with the recovery discs still doesn't solve the problem!! 

Is this what you wanted to see? Sorry I dont know much about these stuff. It says "This device is working properly". I'm pretty close to giving up now. Guess there is no solution for it

I always run it on power saver so thats not the problem. Yes I use HP battery check everyday. And after every charge, it loses 2% of its full charge capacity

BTW, does any of you guys know what the "(1)" is in HP Battery Check next to my battery condition?? It says within brackets "(1)"

I really dont know what to do. I love the notebook. But I cant keep changing batteries like this!

Still the same :( It keeps reducing... I dont know whats going on. This is definitely a Windows problem... I feel ripped off!

Yeah thats what I'm gonna do now. Thats my only option. I'll run Linux and report back in a couple of days. Thanks for all the help guys. It means a lot to me. Hopefully, the battery will stop dying on Linux

Guys! Sorry for posting on this old thread but I had no choice!

I recently ran a battery test using the powercfg -energy command in Windows 7 and the results I got were quite weird. The design capacity and the full charge capacity are exactly the same!! I tried this with 3 batteries. All the same.

Here's my old battery

And heres my newest battery

This is wrong. The Full Charge capacity should be lower than the Design Capacity right?

You guys think maybe this is why my battery life keeps reducing everyday??

Well... anybody???
