Question about HP Pavilion a450n PC Desktop
Hi there! I have a HP Pavillion a450n that is just about 3 years or a bit older. It works wonderfully and I've really had no problems with it. However, yesterday I went to turn the power on with the power button on the front of the tower and it would not turn on. Since I have it plugged into a power strip with the other peripherals, the small green light on the back of the tower was lit up. The power button does not appear to be "stuck", but I'm not sure. I have unplugged the tower and let it rest and reset overnight. I have also checked the connection of the cords on the back of the tower, but as I mentioned, it must be getting electricity, because the small green light on the back of the tower remains on. I have sprayed the vests with compressed air to rid any dust on the inside. Has this happened to any one else? Can it be fixed without taking to a Best Buy or Circuit City (my friends have had some horror stories about their files being lost or erased when using their services). I consider myself average or slightly above as far as computer literacy. I'd appreciate any feedback from anyone, especially the Experts! Heidi
Hi, I have seen this problem before and it was related to circuit failure, let us hope this is not the case! From your posting I understand that your computer won't turn on now. So the next step is to reseat the components inside the tower. The first thing you need to check is the connection from the switch to the mainboard. Open up the case and follow the swith wires to the main board. They should be blue and white wrap around each other.If the connection looks fine then disconnect it and then reconnect it. Try the power the computer on. If it doesn't come on then we will need to do the next step. Open up the case and remove the RAM and place it back in, then diconnect the hard drive and reconnect it. Then disconnect the powersupply from all everything including the mainboard and then replace it. Then try to power it on. If you need help with any step of this posting feel free to start a live chat with me and i'll walk you through it. Let me know how it goes. Good Luck
