Thanks for the information.
The dv6000 models are well past the date that we expected the battery to last so here's the deal. Most folk will never put in a new battery when it's called for. And no shop I know of will loan you a battery.
Then we have the dv6000 story. It's not a good one.
You'll have to tell me this battery is less than a year old to make me think it's the motherboard.
