Upgrading their LG notebook to Windows 7 has left some customers scrambling for new batteries after the new operating system suggested they needed to replace their old one, and scratching their heads when the “Consider replacing your battery” persisted.

Microsoft confirmed that users were seeing a warning message immediately after they made the jump to Windows 7 on certain LG notebooks, instructing them to replace their laptop’s battery.

However, customers that went ahead and swapped existing batteries or new ones, continued to see the message from the Windows Battery Meter.

The software giant explained that Windows 7 is not at fault for the problem. According to the Redmond company, the erroneous “Consider replacing your battery” messages are generated by a code defect in the system firmware (BIOS) of some LG notebooks, including the R500 family of laptops. More »

Well, it appears that there are some exceptions. According to the Redmond company, Windows 7 can also present incorrect “Consider replacing your battery” warnings.

This can happen to users running older HP notebooks with the last Windows client from the software giant.

Such customers should disregard the message from the Windows Battery Meter, and the additional warnings from the OS.

“Additionally, a red “X” may appear on the battery icon in the notification area. However, the battery may still be in sufficient health. This issue is known to occur on the DV9000 and DV 67000 series of notebooks,” the software giant said.

Microsoft blames the problem on the fact that the older notebook models were not designed with Windows 7 in mind. More »
