Hp 1270n power problems

I have recently moved and my hp won't turn on. I plug it in and the green light on the back starts flashing, if I unplug the mother board the light on the back stays solid green. Otherwise nothing else happens, no fans no light in the front nothing. Any suggestions?

First remove the power plug from the smps and press the power switch few time and wait for few minutes the re plug the power connector to the smps and switch on the computer if you still dont have power then you will have to check whether the smps work to test that its not enough to test the voltage in the 21/24 pin you will have to short the green wire and the black wire and see whether the smps fan is working if the fan is not working then the problem is with smps

After a power surge computer will not come on green light on back is on. What could the problem be ?

Sometimes this can be caused by a surge. Unplug the power cable from the unit, attempt to power the unit on without the power cable plugged in. Obviously it won't turn on, but it's what we want. Re-insert the power cable and attempt to power on. Sometimes this is an easy fix. If this doesn't work, you might want to take it in and have a technician look at it.

Good luck mate.

Outages are frequenly accompanied by power surges. It sounds like your power supply got cooked and does not produce enough power to start your computer anymore.

They are inexpensive and are easily replaced. Take a couple of digital pictures of it in your case and then remove it.
Measure the dimensions and go find an ATX power supply that will fit. I recommend that you go up to at least 350 watts. Use your pictures to help you install the new power supply.

If this helps please vote for my solution.

Green power. HELP!

This could be a problem with your power supply. If the motherboard sees that the voltages from your power supply are low, it will turn itself back off.

You can test your power supply by unplugging all of your internal power cables, ground out the green wire on the 20-pin/24-pin ATX connector and check your yellow (12v), red (5v) and orange (3.3v) wires. If the voltages come back more than 10-15% off, you will most likely need a new power supply.
Even if you have good voltages using the test method above, it is only an indication that your voltages are good at zero load. Your power supply may still fail under normal load. If you have recently added any hardware to your computer, remove it and try again. If this still doesn't work or you haven't added any hardware recently, replace your power supply.

Wont post.

Try a few things for me OK? From what you typed, turned on the psu "the toggle switch on the psu", pc seemed to be starting up. I need you to keep the toggle switch on the power supply in the on position. Press and hold the start button on the PC case to shut it down. Give it a few seconds & power up by pressing the power switch on the case. Notice a differance? Next, unplug everything connected to the pc expect the monitor, mouse & keyboard. Try to boot. Still no? Remove the side of the case exposing the board. Turn the psu off by flipping the toggle switch on the psu, wait till the green light on the board goes out. Grab the Mb ( I know it's tight in there) and see if you can move the board in any direction. Not loose? Re-check all data & power connections for a solid connect. Re-check your case to Mb connections. Also check the PSU, there is a red slide switch it should be set to 115v. Post your findings..
