Hp Pavillion a420n blinking light

Hi

i left for spring break and turned my computer off. when i came back and tried to turn it on it wouldn't. so i looked in the back and saw that there is a blinking green light and its not solid. I tried the methods to turn it on like switching power cords,taking it out and holding the power button, and switching the voltage switch but nothing works and nothing happened while i was gone like a power outage or anything.what do i do? please help

    I have the same problem with this machine. The light only blinks and there are no sounds. The system will not boot at all. I have tried what you suggested and it hasn't worked.

My hp pavillion a420n keeps shuting off and turning itself on every once and a while. Also othe flash keeps crashing and programs keep failing. Any clue what it may be telling me?????


Hardware failure - the voltage to the processor is unstable because either the PSU or the rectifiers on the motherboard have aged. Open the case and look at the motherboard - if some of the capacitors on it are bloated then you will have either to replace them or the entire board. If the capacitors are fine in there then the fault is in the PSU - you can get a new one for less than $20 at every pc shop.

I have a hp pavillion a820n that will not turn on. There is a green blinking light on the back so I asume it is getting power. Do I need to replace the power supply?


Hi ,

With what ur saying i see that there is no light on the front panel of the computer tower however there is a light at the back which means that the computer is getting power .U need to do the following steps to see if it is the issue with the power supply :
1►Disconnect all the cables from the back panel and open up the chassi

2►Then remove the memory card and then reset the cables for the hard drive, ATX cable (the cable that comes out from the power supply and gets connected to the motherboard),cmos battery(round battery on the motherboard looks identical to the battery that we have for the watch )

3►Leave the side panel open and then try to turn the computer on .If its the same then

4►Remove the memory card and then try to turn the computer on if it does not give a long beeping noise then the motherboard needs to be replaced .. It should be the motherboard as there is a light at he back whic indicates that the power supply is ok .The light ata the back is for the power supply .

ALL THE BEST

My HP a420n won't start after replacing cd-rw drive


Please try to remove all the connections from your computer and also connections inside the motherboard, the power cord for your hard drives and also the power cord from the power supply to your motherboard.After that, remove the memory and clean the pin by using an eraser of the pencil. And then insert again the memory stick and connect all the connections from the power supply to motherboard and everything. Lastly reset your bios and put it back to normal again. Hope this would help. Thanks..

Sounds like the motherboard might be bad but go thru these steps.


Unseat and reseat the memory one stick at a time in each slot one at at time and turn on the computer after each stick reinsertion.


If that doesn't get the video to come back up then go ahead and unseat and reseat the CPU. Then try turning on the computer.

If that doesn't do it, make sure there is no power going to the hard drive or the dvd drive. Then try turning on the computer.

If you do all of these steps and you still have no video, then the motherboard is bad and would need to be replaced.

I have a blinking green light on the back of the PC by the fan. What does that mean


That all depends.
Some computers have a small cluster of 4 leds that are used for diagnostics or if you have your computer on a network (cat 5 ethernet cable) plugged in then all it means is that there is activity on the network.
