E65 Turns itself off when it pleases!

Question

Hi, my E65 turns itself off apparently as and when it pleases. Sometimes as many as 5 times a day, but on other days not at all. Sometimes it happens when I close it after a call. and other times it goes just when I want to answer a call. Has anybody else had this happen? if so what can I do about it?
From a business point of view, I need my phone, but if I can't rely on it, I'll go looking elsewhere. Thanks in advance.

If your phone appears to have problems with power, the problem may be with the phone, the battery, or the charger. Before bringing your phone into a Nokia Care point for inspection, please perform the following checks:
* Fully charge the battery according to the instructions presented in the user guide.
* Remove and re-insert the battery according to the instructions presented in the user guide.
* Check that you are using a Nokia battery and charger compatible with your phone model. You can check compatibility from the Battery Compatibility Chart and Charger Compatibility Chart.
* If you have access to another battery and charger of the same type as yours, try substituting them to determine if the issue is with the phone, the battery, or the charger.
If you are unable to test your phone or it still keeps switching off, please bring it to the nearest Nokia Care point for inspection. You can find Care point addresses from the drop-down menu to the right
