Re: hp pavilion a503n

Hey, If you have switched out the power supply with known working and it still doesn't power up then it might be your motherboard has gone bad. What happened the last time the PC was on? Did you power it down normally and then it never came back on?

Why is my hp pavilion a1220n product number ED904AA-ABA?

Try removing the 512 MB memory to see if it does work with the 1GB stick only.

It's not the power supply that does have a problem. It has something with your memory stick.

Hp pavilion will not turn on at all, just the green light flickers at the rear of the tower?

Could be a number of things wrong with this tower.

-If the computer stays at a black screen with a white cursor, it means it's missing system files and the operating system cannot start up. A reinstall is needed.

-If your computer won't power on, it could be either the power supply or motherboard, or sometimes, both.

-Also, check to see if the RAM is properly inserted into the proper slots.

Hope this was helpful.

HP PAVILION A 1520N pc DESK TOP does not turn on when power button pressed. has power to end of cord. Power button does not light up. little green light on back by power source blinking green

Bad Power supply. Look on the side of your current power supply and find the wattage rating, and buy one of the same rating or higher. Some place like newegg.

Hewlett Packard Pavilion Tower Button Flashes for a second but will not power on the tower. The green light in back is on and power source is fine. How can I fix this?

Sounds like the power supply is bad. That's the one inside the tower.

You could try blowing dust out of it,  reseating the connectors. But I have a feeling it needs replacing.

Tower won't turn on. There is a green light on the back near the power cord that's flashing green.

Pull the power cord out and allow it to reset. If you still have issues you may need to replace your power supply.
