Driver for Smart Battery not working...

Hi,

Vista could not detect the driver for my Laptop's smart battery. If I choose
Microsoft Smart Battery driver for it, the installation will fail. So I have
to follow the following steps to make the installation successful.

1) Install the Microsoft ACPI-Complaint Control Method Battery for
ACPI\ACPI0001 (Success)
2) After the success in step 1, Vista will detect another device
ACPI\ACPI0002
3) Repeat step 1 for the device found in step 2
4) Reinstall the driver for first and second device using Microsoft Smart
Battery subsystem. (Success)

Anyway, even though the installation process is successful, Vista still does
not detect the battery. Anyway, now Vista recognize my laptop as a Mobile PC
(which it does not before).

Anybody has any other solution to this?

Thanks.
