"Consider Replacing Your Battery"

After reading all those post I have come to the conclusion that all Windows 7 is doing is relaying information that it receives form other hardware or programs. Yesterday you had XP with no battery warnings and today you have Windows 7 and you have battery warnings. Simple to me. XP didn't tell you and Windows 7 can. Put a new quality battery in and give it a try. I have battery powered tools with 4 batteries that cost $120.00 each. When one battery starts loosing power much quicker than the others I replace it. That is just the world of battery powered anything. I have noticed that some battery manufactures recommend running the battery all the way down before charging and some don't. IMHO netbooks, notebooks, laptops are not designed to be PC'S. If you try to use them as a PC the battery will not last as long because the battery is being charge more often and creating heat. Batteries come in various qualities and price ranges. Buy the best you can get if you have a choice. Read the manual.

All the posts? Are you sure? I'm a systems admin. And own 6 different laptops. Don't you think I'd know bad battery on a laptop when I see one? I've said numerous times here that this bug DOES NOT affect all laptop models. Only certain ones. The laptop I had problems is only 6months old, barely used. I had to replace the batteries TWICE. Went back to Vista, guess what... all is fine now. This bug can be fixed with BIOS updates. But the thing is, it sucks to find out after your batteries have died on you and cost you a bit of $$$$. Cheers.

I have no idea what other people know or don't know. I'm really trying to understand how a operating system kills a battery when millions of laptops with Windows 7 don't have this problem.

How I fixed my "consider replacing your battery".

1) Adjust all setting in your power scheme to minimize actions when the battery is low. (turn off all sleep or hibernate commands and reduce all warnings to 0 or 1 minute).
2) Run the following command:
To change the 'Battery->Critical battery action->'On battery' setting to "Do nothing" using powercfg.exe

1. activate the power scheme you want to modify.
2. open an elevated command console (windows key, type 'cmd' in start menu, press "ctrl+shift+enter", click 'continue')
3. execute "powercfg -setdcvalueindex SCHEME_CURRENT SUB_BATTERY BATACTIONCRIT 0"
4. your current power scheme will show "Battery->Critical battery action->On battery: Do nothing" despite the option being unavailable in the drop box.

3) Run your laptop until it dies...your pc will fully crash. Then fully recharge and run until it dies again.

This will recalibrate your battery. Because Windows 7 automatically shuts down your PC when it thinks the battery is low, it never recalibrates. You have to stop if from sleeping or hibernating all together to get the battery to recalibrate. I went from 66% battery wear to 0.0% overnight.

I have abruptly the same problem. What if I disable Microsof ACPI-Compliant Control Method Battery in Device Manager? Following your remaining instructions?
Thank for an answer. Ciao,
Stefano

well i am going to find out if the problem really was just the old battery, i bought a non-genuine 12 cell replacement (brand new), and power brick. It is just charging now for the first time, and heres hoping i dont have to quote this post with a complaint at some near future date!

It seems Windows 7 was just telling me the truth, the new battery is working fine... The only problem to this theory is that i bought a hi-capacity version of the standard battery (12 cell vs 6 cell), and i have been reading on the net that quite a few laptops have BIOS that report incorrect battery capacity back to the OS, which means that even if my 6 cell was in good condition, Windows 7 would be told its capacity was much reduced.

Okay guys, this didn't happen to my computer. It was my friend's Asus F6v she has owned for 2 1/2 years. Here is the interesting part: She was reinstalling 7 and didn't have the battery message prior to the new installation. I will edit this in the morning when I have a proper keyboard (my laptop is having some issues XD).

Bullshit !
"Consider your battery" is nothing more then 1 stupid bug which microsoft didnt solved.
How to solve this problem ? Simple, just install Vista Basic as i did and after that reinstall on Windows 7 64 bit.
Problem solved.
