1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
4. The power button could be bad.
5. The motherboard could be defective & needs to be replaced

HP Pavilion a1020n will not power on.


The green LED light at the back of the Power Supply, is now a diagnostic LED light.

Tells you the Power Supply is bad.

HP Support > Pavilion a1020n Desktop PC > Main Support page,

http://h10025.www1.hp.com/ewfrf/wc/product?product=459880&lc=en&cc=us&dlc=en&lang=en&cc=us

Solve a problem > Start-up / Shutdown / Power >
(No Thanks) > Power management,

Scroll down. Click on the + sign to the left of the blue -
Power supply light is on or flashes

(When the PC worked the green light stayed on constantly. You are correct)

Now,...
1) Is the computer dirty inside? Need to know how to properly clean it?
2) Would you like to know the easy test, to see if the problem may be a $5 ATX power on switch, or the Power Supply?

3) I also suggest you remove all ram memory modules, ('Stick'), and clean their gold plated contact pins, with an eraser.
There is a proper procedure for this.

Post in a Comment if you wish to know.

HI There

Sometimesa power supply will start up giving 12V and 5V, but this drops to below what the computer can handle, and the computer therefor switches off. try another power supply (borrow from someone if you do not have a spare) and it should be at least 250W. If this sort your problem out, its the solution.

UIt could, however also be a main board problem, which is more expansive to replace.

Power supplies tend to be either working or not working. I would start with the computers memory, reseating the memory cards (there are plenty of tutorials on the web for how to do this). If the power supply fan was running, chances are you did not need to buy a new one. Does it do the same thing with the new power supply?

Hp pavillion 620n will not power on the light in the back is flashing was told it is the power board someone. Can this be true and can it be replaced?


To determine the cause of the problem, disconnect all power cords from everything in your machine, and if the light is off, your power supply is bad. If the light stays on, something else in your computer is bad. Most likely the motherboard, but also possibly the processor.

Hp pavilion 513n tries to start up then turns off


This is a case where something that is getting switched on during start-up is causing the power supply to fail... probably due to a short. How ever I believe the short is in the power supply

This is an older HP model ( I have a 530N) with teh same problem. I bought a new power supply and installed it.

Hp pavilion f1703 blue monitor power button flashesw/ dark screen


Have you tried connecting this monitor to another computer, even a laptop. This would tell you whether the display is bad or the video card is the culprit. I suspect the monitor's power supply is dying. Taking it to a pro for repair should cost @55.00. Buying a new monitor @ $100 - $125.

Power doesn't turn on


NO! Do not buy a new motherboard or pc without checking some things.

First, is the green light you say is blinking on the Power Supply itself?

If it is, then the power supply is dead. A blinking light on a PSU means that it can no longer hold a charge and needs to be replaced. Get a new one and pop it in.
