I use N800 OS2008

3 batteris that I charge separetely and then I put them in the tablet and it works fine.

The problem is: when I try connectiong the recharger directly to the tablet, it does not recharge it and there is no sign the it is connected.
checking the battery ststus icon sying the time left and doesn't say "recharging" as it was before, the same happens when trying to recharge when the device is turned off, it just does nothing.

Anu ideas?

Thanks
