Hello, Iam having a strange problem I installed maya and now kde 13 and got the same issue ... The battery indicator works fine in live mode using my usb drive but once I install the system to my hard drive the power indicator disapper which is very annoying to a laptop user because I can't see the battery level and the laptop just shutdown without any notifications when the power runs out . I tried to add a widget that shows the battery level but it looked like it didnt detect the battery! it's a brand new laptop and works fine with Windows 7 . If anybody ran through a problem like this please advise.
I had a similar problem with Toshiba laptop... some sort of incompatibility kernel <> Toshiba acpitable. And the fix was to modify kernel. I gave up. That was my first disappointment in Linux Mint. The second was - I couldn't install Huawei 3g modem. Not even with a sakis3g script. It was there, but always disconnected.
