i had this experience on this issue before and replaced MFPB and SSD at same time, fixed !
caution, counter all will be zero.

my c224e also encountered the same problem after unplugged from wall for several months.
may i know how to replace the battery myself?

1) Figure out what battery is in it, buy one.
2) Remove the circuit board from copier.
3) Make use of your excellent soldering skills.
4) Reinstall board.
5) Follow instructions from an earlier post to bring it back to life.

Guess you need a little luck. We had a few cases with success and some without - I recall at one time we also had to put a new ssd board in to revive the MFP board but in and start the MFP with the reset tool (after battery change of course) another case that "final attempt" didn't helped, too. Guess there's no 100% success guarantuee for these procedures.
