Just tried another battery from another similar Samsung and it was fine - so I guess the batteries don't last long
This lappy was bought for the neo08 so its only a little over a year old and not been used that much since I have a PC at home, it's mostly used for races and mostly plugged in all the time.
The worry this weekend (before my replacement battery arrives) is that the power will go off and I lose the race report at some point(s) which will be a bit pants. Oh well it could be worse I guess.
