Microsoft warns that HP's DV9000 and DV 67000 series of notebooks running Windows 7, may incorrectly receive following warning message from the Windows Battery Meter: Consider replacing your battery. 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 occurs on these notebook models, which were not originally designed for Win7, because the system firmware (BIOS) incorrectly reports the Design Capacity of the battery to the operating system.
There's a Windows update that remove the incorrectly reported battery message for only the affected systems.
Additionally, HP provides a Battery Check Utility that may be installed as part of the HP Support Assistant. Running the Battery Check Utility will give an accurate view of the battery health and whether replacement should be considered.
