Hi guys and gals I have Vista Ultimate running perfect on my Acer Travelmate 4002 WLMi notebook. Unfortunately, in the power icon, it is said, that no bat is detected although the Vista Performance and Reliability Tool tells me the exact specifications of my bat. I have heard, that Linux had the similar problem before, solving it by replacing the DSDT table in the BIOS. I have that DSDT table. How is it possible to change that table with my original DSDT table? Thx for advice. Maschdel
