That tends to happen when the laptop battery is kept at a high temperature for long intervals.
My work laptop security doesn't play nice with Windows Update, so "update and shut down" actually does "update and restart" and proceeds to incinerate the laptop in my bag until the battery is exhausted.
Took me a while to figure out why my batteries would turn pillow so frequently.
I don't really ever travel with my laptops, at least not to put them in bags. I think the Mac laptops had a known issue with defective batteries, though.
