I had my laptop on bed sitting on blankets and i was online then all of a sudden i heard this crinkling noise, then my hp pavillion dv1000 went totally dead! No power. What do i need to do to get it running again??
Yikes! I have an HP pavilion laptop as well, and I have had a number of power issues in the past. There seem to be two things that consistently happen to me. First, your battery may be improperly seated in the laptop. To check this, just pop it out, wipe off the connectors with a clean, dry cloth, and put it back in. If this was the problem, your laptop should power right back up and the battery will be capable of being recharged again.
Second, if you are having this problem when you are plugged in to AC power, check your power cord. I have a tendency to absolutely mangle mine (something about getting them caught in the metal workings of my recliner...). If the power cord is damaged in any way, this can prevent your battery from recharging, and also make it impossible to turn on the laptop once the battery is drained since as far as the computer is concerned, it's not getting any power. So check your cord for any damaged sections, particularly where it connects to the rectangular converter part, and by the little connector piece that goes into your laptop. The cable in these places tends to get twisted around during use and the wires inside the cable can break as a result.
If neither of these things is your problem, there are two other possibilities I can think of if your laptop runs on AC power, but not on battery power. First, your battery may be permanently dead. While the Lithium Ion batteries last quite a long time, they have a limited number of recharge cycles before they eventually need to be replaced. Second, the manual I got with my replacement battery mentioned that in very high temperatures, the battery may shut the laptop down to protect itself. If this is the case, the manual indicated that waiting about an hour and then trying to power up (preferably in a cooler location) should do the trick.
