Thanks for your help Nick,
We had already tried checking out the battery and all was fine on that front…
Good new though 😀 after spending a good 12 hours on trying to fix it with various software versions etc. and trawling thorugh these forums, we finally found what the problem was…The u106 chip needed a little push back into place (we also pressed all the other chips t make sure so it could have easily been one of them as well or instead).
The unit is fully functioning again now, and in time for the weekend 😀
