    Did you have this problem immediately after installing W7, or just recently?

    Hello Shafichariri,

    You might double check in your advanced power plan settings under the Battery option to see if it may have been set to shutdown the computer when the battery level reaches that level, and make any changed as needed.

    Same thing happened with my laptop. Right after Win 7 beta install it would trickle down to about 60% then quickly flatline.

    Plug it in and it shows 5% life/charging.


    I was hoping the RC and various chipset updates along the way would fix it but no joy. Running the battery down, etc doesn't change it.

    I prefer NOT to install XP simply to see what happens lol.

    The laptop was on Vista before and battery life was fine.

    Something else it does is that upon wakeup (not reboot) it will not engage the CPU fan unless I manually change the power state, such as Power-Save to Balanced. And it doesn't matter which one it is just that it has to be changed.

    When that happens it means the battery can no longer hold a charge. The battery is at the end of its life.

    You got a bad battery, or the environmental conditions caused it to speed up its life. Long prolong periods of heat can do that along with other environmental factors. Even the manufacturing process can determine its age. Also letting a battery reach absolute zero can also cause permanent damage.

    Installing Windows 7 would not have damage a battery in any such way.

    So it just happened to occur after installing Win 7?

    I think not. Something is up with laptop power management caused by Win 7.

    It is your hardware. If there are false readings it is the hardware and supporting software that communicates and translate with the hardware. A bettery is a read-only device if it says it has 5% left, it has 5% left the OS cannot change that.

    Windows 7 uses Advanced Configuration and Power Interface (ACPI) if the underlining hardware does not support this standard to to spec, is that Window's fault? No. If you believe your battery is fine, then you need to talk to the manufacture of your computer. Either they need to provide a BIOS update or a driver.

    I am typing this on a laptop, which has had zero battery issues since installing Win 7 since beta. As well as on a Netbook I got at the end of 2009.
