Hp pavilion 21 touchscreen all-in-1 not turning on

[C00kie0977]

I had unplugged my hp pavilion 21 touchscreen all-in-1 and had plugged it into another outlet. I then had plugged it into the original outlet after I moved an ac from one window to another-not sure if it was in sleep mode before I switched the plugs around. While I was moving my desk the ac adapter had fallen off the desk and I put it back on. The computer was plugged in at the time. We'll now the computer won't turn on. When you plug in the adapter, the light is on in the back showing that it has power. The compter won't turn on, and you can't hear any motor or fans on. Nothing, completely dead. Had tried another ac adapter, and it still won't turn on. Any suggestions on how to get the computer to turn on. Had pushed the power button many times, held it, etc and still nothing. Thanx

Have tried all the steps in the troubleshooting guide. Also used a different adapter. None of them worked. Still can't get the computer to turn on. I had read that there could be a problem with the motherboard or the power switch. Not sure if I shorted something out when I had unplugged it or if something happened to the switch or motherboard when the ac adapter fell off the desk while it was plugged in. Any ideas of what is making it misbehave? Not cherishing the idea of spending $200 or more to get the computer fixed. If I called phone support, how would they know what is wrong with the computer without looking at it?

Ok ended up doing several things. Took a look at the ac adapter connector that plugs into the computer. The center prong was bent. Fixed it, and plugged it into the computer. When I pushed the power button, it turned white, but still didn't power on. Tried unplugging adapter and plugging it in. Pushed power button and it still didn't work. I ended up taking the cover off. Replaced the cmos battery, unplugged the connectors to the power supply, and replugged them in. The connector looked loose. Anyways, I put the computer back together, and guess what. It started. Had to reset the time and date on it. Not sure which of these steps worked, but now the computer is working. Yippee. My kids are super happy.
