    Hi guys and gals
    I got an Acer Travelmate 4002 WLMi notebook.
    I have the Phoenix BIOS 3A10 and the OS Vista Ultimate.
    My notebook is faster and more stable than under XP.
    The only point of sorrow is:
    I got a power icon, saying: NO BATTERY DETECTED.
    In my device manager, the devices: MS ACPI conform controll method battery and MS Smart battery subsystem
    seem to be correctly installed and in their properties it is reported that those devices work excellent.

    I have talked to some people of MS and Acer.
    Both parties say, that it is need of a new BIOS, including the Smart Battery in the ACPI tables.
    MS says, it is not their job and Acer says, they don't feel responsible for it.

    Searching a bit more, I found this problem occuring since 2005 in several Linux derivates and Ubuntu.
    They somehow changed a DSDT part and everything works fine.

    I beg you in the name of more than thousand users.

    Please help.!!!

    Does it matter?
