Having problems with your HP Pavilion a305w (DM181AR) PC Desktop ?

PC will not turn on....plugged into power supply the system only blinks rhythmically at me and will not respond to On button. What part of the PC needs to be replaced to work again?


Answers :

Please start by working through this HP support article for your power issue. Having said that, the most likely culprit in such cases is the power supply itself. Even if some lights are lit, it could be bad. You can have it tested easily by a local computer tech, who can load test it to be sure it has indeed failed, and usually provide you with a replacement for about $30.00. If you want to investigate testing it yourself, see the links to do so accessible from this general startup troubleshooter.

My HP Pavilion dv9005us has two issues which I cannot resolve. The wireless device is not even recognized or detected by the computer, and there seems to be an electrical problem where the lighted buttons at the top flicker on and off from time to time, which may also be linked to an issue where the computer will at times refuse to turn on after I press the on button and watch it all light up in response and immediately shut off. Any help with this would be greatly appreciated.

Power button lights, doesnt blink, but no other buttons function, either on remote, or on monitor. I'd dealt with this by unplugging the monitor and it seemed to "reset", and the when plugged in again, the button didn't light and the monitor functioned normally.
