Someone gave me an HP Pavilion dv6700 series laptop because they didn’t want to pay to have it repaired. It was a fairly nice laptop, Dual Core 2Ghz, 3GB RAM, 250GB hard disk, webcam and all. The problem they were having was that it would power on for about 3-5 seconds, then turn off on its own. They would have to remove the battery for about 30 minutes before they could try to turn it on again.
I tested the power supply and was leaning toward the battery being faulty. The only thing that kept me from replacing the battery was the fact that when plugged in without the battery, the symptoms were the same. Only 3-5 seconds and it would power off. I googled the symptoms for the dv6926nr model, but couldn’t find anyone with the exact problem.
Finally, I smartened up and hunted down the HP laptop manual. One of the suggestions was to unplug the power, remove the battery, and hold down the power button for 30 seconds. Plug it back in and replace the battery. Normally, resolutions like this are just another step in a flowchart that tech support will walk you through when you call. I figured I had nothing to lose and tried it out. Sure enough, it worked. I’ve been running it for about three days now without incident and even replaced the crummy Vista with Windows 7 Home Premium. (FYI – you won’t find Windows 7 drivers for this model on HP’s site, Windows 7 includes most, and you can use the Vista drivers for the missing devices)
Anyway, to recap:
Remove the battery
Unplug the power
Hold the power button down for 30 sec
Plug the power back in, turn it on
Replace the battery
