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.!!!
