In desperation I was thinking of opening it up and disconnecting the battery
Not sure it would work as I never opened a pad up before a tower yes a laptop yes but not a pad
Anyway unscrewed the 4 very small screws and was just going to take it apart when what I though was a very small crack appeared in one corner so quickly put it back together
They are very flimsy once you take out the screws so that was the end of that
It looks like it's going to have to be put down to a bad experience and get a better pad
This one needs putting down
Or throwing out the window from the 13th floor
Thanks for all help and advice anyway
