![]() I cannot find a pinout for this battery I can work with, so I’m hoping someone here has one I can use to at least jump it and see if it’s the battery or motherboard. This protects the user, but requires these to be jumped to use them once it happens. I’m suspecting charge rejection because modern BMS boards (even copy onses) have onboard lockouts that create this problem. I’m going to keep the notebook if it works (even though I’ve moved onto something newer, since I don’t want to waste this one) but if it doesn’t I’ll relegate it to a throwaway loaner with the caution it can’t charge batteries until it gets worse. I’m going to keep what I put in minimal for safety reasons unless I somehow need more (3.7V max to start). Since I do not know if the notebook even works (or if the motherboard is bad), I would rather not buy a battery and see if my existing unit is jumpable to get it to a state it’s going to even work at all. I also see it does hold a few mV of charge with a multimeter.
