>From the log¹ for my Dell D430 laptop:
"2010-04-23 One of the Dell chargers started to beep very quietly to
itself. Although it was powered, the green light was out. Switching it
on would make the green light come on for a few seconds, then it would
go back to beeping."
It was one of those sledge-shaped chargers with the peculiar
backward-facing figure-8 plug on its cord; the IT dept
replaced it. Four years later, the last battery gave out,
and the charging circuitry too. Now the laptop only runs on
a charger, and needs a monitor too because the screen blanks
itself most of the time.
