The battery is shot. The logical thing to do would be to remove the battery, and try powering up the laptop with the adapter only. If it powers up fine, then the battery is likely the only issue.
Maybe someone has already asked this question, but I didn't find it.
I have an HP Pavilion dv6000. It is 3 years old and has always had terrible battery life. When I first got it, the battery only lasted for about 45 minutes but for the last year or so it only lasts about 10 minutes without being plugged in.
Last night I tried to turn it on (for the first time for maybe 3 days) and it would start whirring like ti was starting up and the lights would turn on but then it would just die and then it would try to turn itself on again. It did this probably 3 or 4 times. Finally I just shut the top down and gave up. Then I noticed that the battery charging light was off. I checked the cord but it was plugged in and the blue light was on where it plugs into the computer, so it was receiving power. I unplugged the cord and plugged it back in and the charging light on the front of my laptop turned on but then turned back off maybe 30 seconds later. That makes me think it is the battery.
If it makes any difference, I bought a new cord from HP maybe 3 months ago because I lost my original at school.
Do I need to buy a new battery? Anybody have any ideas? Thanks.
