2628 says optimized charging... - GSM-Forum

airboy · 09-12-2002, 17:26

I have one 2628 with this problem:
I turn it on, everything is ok until it registers to network. after that it says "Ericsson optimized charging" and beeps once or twice / second . Of course, i haven't connected it to the charger.
If no sim or antenna dismounted so it can't find the network everything is ok. I have tried to rework the SMD-s and BGAs on the mainboard but no success. Same problem. Phone works but always beeps and displays the "Ericsson optimized charging" message. I can only turn it off by removing the batt.
Sometimes it does not do this few seconds after that it starts beeping and displaying the charging message again.
Is this sw or hw problem?

Why did you repeated this ? It's my post :P

To resolve this just change RF signal processor (30042rc2, or something like...) ! Yes - it's true - not a mistake!
