As you know my laptop is newish. Not in days now, but I've hardly used it much as I'm using this old desk top til it wears out.
But....... it looks like I won't get much time out of a battery, because if I use it for say 1 hour, I get a 60% full reading on the battery meter, so I run it plugged in 95% of the time.
I've not been away yet to take the laptop with me out of the house, but that's when I'd be using the battery more. Won't be very good if it'll only last 2 hours on battery.
Mine's a Dell Inspiron too DM.
