OK I will try a new battery but when I test the battery it shows 4 volts on my voltmeter when charged which is better than the quoted 3.6v on the battery.
I hope that sorts the problem
Ok, have ordered a battery - should be here in the next few days - will try it out after a full charge.
New battery arrived. Charged overnight. Put in the camera, but I still have to press the Menu OK button and wait for it to wake up! Is there a way to reset the camera and would that help?
Have just reformatted the card (shouldn't make any difference - I know) and reset the the camera - That did work! It now seems to wake up immediately and be ready to shoot !
Don't know if the battery helped - I haven't tried it with the old battery yet.
