Greetings. I have an HP Pavilion dv7. It will not turn on with just a battery (fully charged). If I try to turn on without AC, nothing happens. I then have to do a power reset (remove battery, remove power cord, hold power button for about 10 seconds) and then I can turn the laptop on with the AC plugged in, but no battery. Once it is on, I can put the battery in, remove the power cord and run on the battery alone. But I cannot turn the laptop on with only the battery. Any help would be greatly appreciated.

Thanks for your input, but I'm sure that's not it. I've tried three different batteries, 2 of which are new. The one I'm using now will power the laptop for over four hours, once the computer is on.

Thanks for your suggestion. I have calibrated the battery a couple times (though not exactly the same way as indicated in the youtube video, because I cannot turn the computer on as indicated in the video) but I still have the same problem. Also, the battery test in the HP Support Assistant says the battery passes.
