[QUOTE="hughvane, post: 736915, member: 56231"] How about testing the present battery first? Take it out and test it with a multimeter. If you know a friendly registered electrician, that would be best, because he would have a meter which measures higher amp readings than the diy-type multimeter. A battery will often give the correct voltage reading (ie. 3.6 v) but that can be misleading. It's how much current that voltage is pushing that matters. If it's not a battery problem, the next port-of-call is the power supply unit, which can also be tested with a multimeter by someone qualified to do it. [/QUOTE]
