i have had another go at installing the upgraded(?) battery monitor. I used the R192569.EXE, which seems to have been the file I tried before, as the unpacking reports the files are already there. The installation process clearly removes the old software - asking me for permission to remove it, and continues to install.
But once it has installed I can't find the new battery monitor, even after a reboot. Pressing Fn + 3 just gives me no response. I also looked in programs to make sure I didn't have to turn it on, but there was no entry for it I could see. I have already upgraded the BIOS to A04 BTW.
Again I have rolled back the system using system restore so I have the battery monitor as originally supplied. Am I doing something dumb here?
