Its strange ... But something happened to my e5 today
it was working fine, I had a call, when I pick it from my pocket it was turned off... I thought the battery is empty "although it wasn't" I tried to turned it on ..But nothing happened just a black screen not even the little vibrate when u turn the phone on.
I tried charging it , tried to take off the sim card and memory nothing worked ...
Any 1 can help ???
Can't even suggest a three key depressed power on "hard reset" with resultant loss of all data, as correct sequence of keys has never been determined for this S60 3rd FP2 device unfortunately.
You may have to visit Nokia Care facility for device software to be re-installed.
Since you have the same concern, I'll try to tackle your issue as one. Have you tried using another battery on the phone? This is just to isolate if the issue is phone-related or battery related. Have you also tried using another compatible charger?
If the issue is with the phone, you'll need to bring it to the Nokia Care Point for an assessment. Bring a copy of your receipt for verification.
