[android tablet] Samsung Tab Battery Icon

[TechSupp]

Daughter has a Samsung Tab 10.1 and it shows the green battery icon on the screen with a red cross through it. It does charge when switched off (did it from flat last night) and it looks to take power when it's on (battery use indicator time stops when it's plugged in). Why does it show all the time, it also does not seem to be recognised by the PC when I plug it in but the tablet pings and the little red cross appears. Googled it and seen various answers from cleaning contacts to using other chargers so just wondering before I chance another charger and cable if anyone else has come across this?

Mine did exactly the same. New cable sorted it.
