HP Pavilion a1514n wont power on. Green light lite on back. Front power button flashes blue when pressed.


That blue flashing light may be a POST code. Does it flash continuously or does there seem to be a pattern to it?

I hope this helps! If this did help you, please give a thumbs up!

Have a HP m7470n. The green power light in the back is constantly on. The power button flashes blue and orange (~3 seconds each). The computer wont turn on. When I unplug the cord and plug it back in, the...


In my case it turned out to be a weak power supply. It would work sometimes and not others. If stone cold, it would not boot. If I unplugged 1 thing, like the hard drive or the CD Roms, it would boot. Tested the old power suppy and it seemed to pass. But once I connected a new power supply, the computer has worked fine ever since.

Wont turn on just flashes.wont turn off just flashes...Is there a reset button??All of a sudden it just stopped and started flashing no warning.


First try to turn off PC by holding power button for more than 5 seconds. Make sure first that your PC is clean inside and CPU is properly connected to motherboard (before you touch inside your PC touch some metal to discharge electrostatic). If it needs cleaning use canned air and paintbrush. Check how memory is connected. Check the Power Supply voltage, if it's ok, first turn PC off,then you can check power button by disconnecting ATX 20 or 24 pin power connector from motherboard and connect paperclip edges to any green to black wires it has to power on your PC. If it's still flashes it's more likely PSU or motherboard issue.
