I installed Ubuntu last night and was extremely happy with how fast and smooth it is compared to the Windows 7 Professional I had on it before. I checked for updates and there were 273 waiting for me! I clicked on Install Updates and let it do it's thing.
Half way through them, I heard the noise that the netbook makes when you unplug the power cord. Since then, it hasn't been able to detect the power supply and has been running off the battery since.
Is there a Ubuntu update that would interfere with this?
