Glad about that - finicky things.
Because of all the protection a Lithium cell needs during charge and discharge, they do get a bit confused sometimes.
You have to be careful with lithium packs, they blow an internal fuse if over-discharged (this is one of the mechanisms to stop lithium exploding or going on fire).
I had to wait for my pack to self-discharge when it decided to lock itself out, unfortunately, Lithium self-discharge rate is very slow, took about 3 months (luckily it wasn't fully charged at the time). Been working for 5 months since absolutely fine.
Classic things that upset the internal logic, is a dodgy connection at mains connector or low voltage connector to laptop, rapid on-off switching tends to confuse them.
