If the laptop was not plugged in then there wasn’t anything maintaining the charge level in the battery. All batteries will self-discharge and will eventually discharge until they have zero charge left. LiIon batteries have a low self-discharge but they also have a protection circuit built in. This draws a small current and makes the self-discharge seem higher than it actually is. The protection circuit is there for several reasons. One is that if the cells in a LiIon battery are discharged to deeply, they can be damaged and dangerous when used. The protection circuit will apparently kick in and prevent the battery from being recharged. It is possible this is what has happened. If the charge level dropped to low while you were away, then the protection circuit would report that the battery was no good. I would not expected five weeks to be enough time for this to happen unless the battery charge was at a low level before you went away. Or the battery was already in a bad state and wasn’t retaining its charge. Note: Discharging the battery to 0% while using should not trigger this. The zero charge level reported is when the cells in the battery are still at a safe level.
I have seen claims that they can be fixed. From memory, it requires disassembling the battery and playing with the electronics. Or, if the cells in the battery are truly dead, it will require replacing the cells. Both of these are considered dangerous if you don’t know what you are doing.
other battery charging info:
to solve my problem what i did was to open the charger, and replaced the cable with a thicker 3 or 4 wire one, but you also have to adapt the plug from the original cable.
3rd party charger usually only have the ground and V+ conductors and no data signal one so the laptop will never charge.
