Just installed Ubuntu 12.04 on a Dell Optiplex GX280 desktop computer. When I hook up my bluetooth mouse and keyboard it seems to recognize their batteries as the actual battery of the computer. As if the desktop were a laptop and it had to worry about the battery levels.
Ubuntu will only stay running for a couple minutes, then I get an error about the battery level being critically low and it goes into suspend mode. I have already tried changing the value in gconf-editor of the critical battery action to "Nothing" , but this doesn't seem to work. The computer still shuts down, which is extremely anoying.
Is there anyway to turn off the power manager for the batteries or delete the critically low monitor?
