This concerns a Motorola T720.
I think I dropped it one time too many. It's dead. Putting it on charge made the screen backlight come on and sometimes it would say "Charging" but nothing else. Would not turn on.
I took out the battery and probed the 4 contacts in every combination with a DMM and got no readings. Figuring I have nothing to lose I peeled off the sticker and pried it open. I do read voltage on the power cel. So I figure that bit of micro circuitry has been damaged. Anyone know what it does? I figure some of it is some sort of current limiter and maybe something is a micro fuse of some sort and that might be the failure point. Is there anything that can be bypassed?
I've already ordered a replacement battery (even though I really should just get a new phone) but it would be nice if I could make this batter work again.
