Problem getting computer to turn on

I just moved my computer to a new location and then I went to turn it on. But the power light keeps flashing and the computer does not do anything. The monitor will turn on. Please tell me what the problem is.

    I powered down my computer and replaced my ancient surge protector with a new one. When I plugged the desktop back in, the power button blinks like a disco light, but the unit will not turn back on.

    I powered down my computer and replaced my ancient surge protector with
    a new one. When I plugged the desktop back in, the power button blinks
    like a disco light, but the unit will not turn back on.





    I have unplugged the unit, let it sit for a while and then plugged it
    back in, to no avail. I have tried plugging it into multiple outlets,
    but the only result is more disco lights.





    I'd look on the bright side and say that I could make the best of the
    situation by dancing to the beat, but then all of my music is on this
    non-functioning computer. . .

Try removing the power lead from the back of pc for atleast 15 minutes and re-connect. It may be a power supply unit fault that is showing connection but not powering the motherboard. Open up the side of pc and check the main leads that come from the power supply unit to the motherboard connection are'nt dissloged in any way, or unplug the motherboard connector and place in again this might re-set it.

Z53 printer cartridge won't move to the left


I would suspect that there is something along the track that's blocking the printhead carrier from moving left. Do a visual inspection of the entire track area. Try ((very carefully - do not force)) moving the carrier by hand and check for a blockage.
If you don't find anything, try unplugging for a few minutes and then try again (powerline glitch?).

Go to Control Panel, (top right View Small Icons). Then look for Power Options. On this page, you'll have the option to leave the monitor on. You should also check "Advanced Power Options". Don't be afraid of the word, "Advanced." It only means "customizeable"

If your mouse isn't waking your monitor, try the keyboard's space bar. I found it works better than the mouse at waking a sleeping computer

Monitor power light is blinking and cannot see anything.


The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occurr are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing statebecause of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Brand new Printer lights flashing


You should install driver first, then connect printer when prompted, then install inks, as it needs the driver to tell it there are full inks fitted, refer to the manual.
