I think I had this same problem once before. It sounds familiar but could use a few more details as to exactly what happens. From what you have said so far though it sounds like either the main power to the PC is switched off, or your power supply for the machine might be bad. First I would try looking in the back of the computer. On some of them there is a little switch usually towards the top that allows you to turn the computers power on and off. If you plug into the wall it usually will come on for a second before turning off and then when you go to turn you computer on if the switch in the back is off you computer will not start if you use the normal power button in the front. I hope that fixes your problem. If that is not the case please give me a few more details on it and I will do my best to help you get to the bottom of it :). Good luck.

My hp pavillion 503n has a amber light in front...power supply fan comes on but doesnt power up


This could still be a power supply issue. You can buy a power supply tester. This will tell you if the power supply is putting out power to all of the cables.
The other cause of this issue could be a motherboard issue. HP would have to replace the motherboard. A lot of the time HP make their mother boards to fit only their cases. This makes it hard to place a non HP board into a HP case.

My HP pavillion a 1630n will not turn on no light or anythhing


When there are no lights, test the power cord and your mains power socket, if these are OK then your switch mode power supply has failed.
You need to remove this power supply, take it to your friendly computer repair shop and get it tested, if it is faulty then replace it with a new one. Make sure the wattage is the same or higher than the faulty power supply..

Hi, my HP Pavillion a1240n won't start up... the wall plugs work and the power supply is plugged in but no lights are showing. I've also been flipping the switch beside the power supply at the back, and...


There are only certain items that will not power up a machine. 1. The power supply itself could be gone. 2. Check your ram. 3. Your hard drive. In most cases it is the power supply. Take out the power supply from the machine and plug it in to a wall socket. If it starts that it is not the power supply. If it doesn't start replace the power supply.

I can not start my PC. It does have a green


Sounds like a defective power supply. Improper power coming from the supply will cause a unit to fail boot. Power supplies are about 40 bucks.

My HP Compaq D530 won't come on. The lights will not blink or anything. I tried to unplug the power cord from the inside for a few minutes and plug it back in. I even reset the cmos/memory sticks. Still...


bad mos feats meaning you need a new psu, the chances of the board being bad are slim if the lights flashed when the power is plugged in, but insufficient power to the main board often the case where theirs not enough 5 volt rail power to run the main board. the molex connectors should be pulled and try turning on the psu without a load. then try to plug the power back in. something may have just gotten lose. if it works then the psu is ok and all's well. mosfeats are transistorized circuits and they can fail on a heavy load on the board. recommendation for a desktop tower not a gaming machine is about 250 to 300 watt power supply atx ;)

On HP Pavillion 512n - When I plug the computer in only the fans work and the light on the switch is on. There is no drive sound and nothing on display. Is it a motherboard problem or power supply problem?


first thing is to check RAM. Some times faulty RAM stops computer to load up and don not display anything.....if the problem persist try to change cmos battery>>> if problem still there then go for supply check>>>>last comes motherboard........

HP won't power on at all~PSU light blinking, then solid, then off


Dead short on the machine causing the power supply to go into shutdown (Fold Back Protection)

Remove all of the connectors coming from the power supply (Label them so that you know here they go back to on the Motherboard and the DVD etc (Including the processor fan one)

Place all of them back one at a time starting with the main one if the led stays on then plug in another till you locate the short.

If the led dies when you plug in the main MB connector then you are in deep brown stuff

All you can do then is to remove the Ram and any other unpluggable device to see if that is the cause

Hp pavillion power problem


Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure:
CAUTION: This product contains components that are easily damaged by ElectroStatic Discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a PC.
1. Disconnect all cables from the computer, including the power cord.
2. With the power cord disconnected , press the power button on the front of the computer for five seconds.
Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
NOTE: If the power supply fan makes an inconsistent grinding sound or stops and starts erratically, replace the power supply.
3. With the power cord removed, flip the red voltage selector switch to the opposite position. Wait about five seconds, and then switch the red voltage selector switch back to its original location. Ensure that the voltage selector switch is on the correct setting, 115V for North America.
Performing this step ensures that the voltage switch is engaged and set correctly for your country/region.
4. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet and test to see if the computer can turn on.
