now it happened to me either - first the N9 refused other power adapters than the original one (not enough power to charge) - since last night it only charges in upright position when the cable ist not fully plugged in the micro USB - so I think it's time to act!

Has anyone a good address in London (or near London - Bath/Bristol would be ok as well - as I'm usually there for the weekends) for fixing that (I'm here until end of Mai and don't have any tools with me to do it myself - even with the right tools I'm not sure ;-) ) - it's a N9 in nearly perfect condition so I think it's worth to spend a few bucks on it
