The elderly (work) HP 2710p Convertible Tablet PC got a bit fatter today.
It’s about 5 years old and had a slim extra battery pack which clipped on the bottom extending battery life from a couple of hours to about eight.
I picked it up from the desktop dock and it felt a bit thicker than usual. Then I noticed the battery had expanded, nobody near it noticed any smell or sound so it didn’t ‘explode’. Fortunately the machine and desktop dock it was sitting in are both ok. I wonder what would have happened if it was left for longer?
Seems this is how lithium-ion rechargeable batteries die. They either fade away, offering shorter discharge cycles, or swell to destruction!
