To be fair, I shut the system down when the battery light started to flash. The version of Unbuntu I have installed doesn’t read the battery life properly – despite reporting 28%, there was probably only about 10% left. I know that //last// time I left it running, expecting auto-shutdown, it ran out of juice and crashed hard.
