When trying to switch on my mobile, it appears to be on for a second and then blackout. This happened during charging. I have been told that I need to reprogram it. Is this so? How do I reprogram it? Thanks.

5.Wait 10 seconds.
6.Press and hold the W key.
7.While pressing down the W key, re-insert the battery.
•The device restarts and after approximately 15 seconds, the 'Recovery' screen appears

mostly nokia chargers doesn't make problems...
just try the following..
connect ur mobile with a system (usb cable)...
found out whether it is charging or not...
if the same prblm appears then there is a prblm in ur cell phone or power jack(socket)...
if it charged with usb cable buy a new charger
Please change Phone Bettery and check the charging

My iphone will not turn on.

you need to reset your iphone. To do this toggle the switch above the volume back and forth two times, the hold the main button along with the top power button for about six seconds or until you see the apple icon displayed on your screen the main menu will appear shortly thereafter. Oh and if you did any charging during this blackout period it is accounted for when your iPhone comes back to life. Hope that helps :)

I just had the same exact problem and it worked!

K750i phone not switching on

You might have overcharged your battery and therefore it wont work. Also have you had a powersurge when it was plugged in? that could completely wipe out the charger and phone.go to a store to get help.
