One thing I have noticed in /var/log/messages is it's full of these:

'kernel: [53379.147068] power_supply hid-00:1e:52:f9:5d:dc-battery:
driver failed to report `capacity' propert      y: -5'

Hundreds & hundreds of lines.

More pertinent are probably these lines:

'kernel: [52915.018110] tg3 0000:03:00.0 p5p1: Link is down
23384 May 26 16:28:57 pathstar NetworkManager[660]: <info> (p5p1):

These came out at about roughly the same time as Thunderbird was
complaining about 'no netowrk connection'

Cheers,
