“Are you getting the error message “Consider replacing your battery” in Windows 7 too often? Microsoft is already looking into the battery issues with Windows 7 and will soon provide a solution for the problem. In the meantime, you might want to try this temporary fix that will disable the error message.”

“In Windows 7 RC and the previous beta, I have been receiving an error message saying “Consider replacing your battery” “There is a problem with your battery, so your computer might shut down suddenly”.

I know for a fact that the Asus N53JQ Battery is good. It works fine in Vista, its only about 4 months old, it lasts 2 hours +, and even in Windows 7, it will last for the same time period as it did in Vista.

People have been saying (as well as microsoft) that it is the BIOS and it needs to be updated. Well, I did obtain the latest BIOS from LG, which is dated in 2009, and that didn’t change anything. I’m concluding that it is NOT the BIOS since vista reported the estimated time left of the battery just fine, even before the bios update, and I have the latest BIOS.

I ran the powercfg -energy command and it says that windows was not able to determine the capacity of the Asus N61J Battery, yet if I go and install the LG batery application, it will tell me all the information about the battery.

I even went as far as to try my friend’s laptop battery which is less than 3 weeks old, and it still gave the same error messages.

Please Microsoft, fix this issue, and if you can’t, then give the users an option to take off/disable/supress the blinking X that is on top of the power tray icon, and to remove both the “Consider replacing your battery” and “There is a problem with your battery, so your computer might shut down suddenly” messages so we don’t have to see that every day, since the Dell WU946 battery is in fact GOOD and works properly.”

CAUSE:
“This issue occurs on these notebook models, which were not originally designed for Windows 7, because the system firmware (BIOS) incorrectly reports the Design Capacity of the battery to the operating system.

The “Consider replacing your battery” message is displayed when the Last Full Charge Capacity is less than 40% of the reported battery Design Capacity. Both the Last Full Charge Capacity and the reported battery Design Capacity are retrieved by Windows from the system ACPI firmware (BIOS). On these older HP notebook models, the retrieved battery Design Capacity is incorrectly reported as 88,800mWh even though the battery’s actual design capacity is lower. This firmware error can then cause the “Consider replacing your battery” warning to incorrectly display when the Last Full Charge Capacity is still greater than 40% of the battery’s actual design capacity.”

Temporary Fix/Solution:

“here is a Windows update that will remove the incorrectly reported battery message for only the affected systems. This update does not change any other behavior on the computer and will not change the actual sony vgp-bps9/s battery life in any way. The update will only be offered if Windows Update detects that this update applies to your computer.

Additionally, provides a Battery Check Utility that may be installed as part of the Support Assistant. Running the Battery Check Utility will give an accurate view of the battery health and whether replacement should be considered.

“The temporary fix for the laptop battery issue is to disable “Microsoft ACPI-Compliant Control Method Battery” in your device manager and you will no longer receive the annoying message “consider replacing your battery”. The disadvantage is that you will no longer be able to see when you run out of battery. If you know from experience that the battery would normally last xx hours, then I would simply install a timer gadget and set up an alert every xx hours. To do that, I recommend the Windows 7 Countdown gadget.

1. Open up the Control Panel:

2. Uncollapse “Batteries” and disable or uninstall “Microsoft ACPI Compliant Control Method Battery”/>”
