After a very short drop in water, followed by immidiate drying by hairdryer,the phone wount start.
I'have tried following:
1. Fully charged (as far as I know)
2. Press ON- and Vollume-buttons for 10 sec.
3. Press the small yellow button under the SIM-lid
4. Tried to upgrade software using Xperia Compagnion - but it fails
5. The PC cannot 'see' the phone in Explorer, ig connect, using the USB-cable.
What to do - more 'hairdrying'?
