When you powered it on, does the power supply fan spinning? If not, then you might need to change the power supply. It may got the led light lit on, but it does not have enough power to turn on the entire computer.

Monitor flashes, turns off


Try to check both ends of the video cable if it's properly connected. Also, check the power cable connections. I'm quite sure this is not an issue of a video card.

My HP D530C does not power on. The power LED flashes 4 times. What is the fault? Pls let me know asap. Thanks.


HP xw6200 Workstation - Diagnostic LED Code: Four Flashes ISSUE: When the workstation is powered on, the front LED might flash red four times, once per second, followed by a two second pause. SOLUTION: The front LED flashing four times is a sign of a power failure. To fix this issue, complete the following steps:
  1. Open the access panel, and check to see if the four-wire power supply cable is properly connected to the system board.
  2. There may be a faulty device. Locate it by removing all devices and then reinstalling them one at a time until the workstation fails. Replace the device causing the failure. Continue adding devices to ensure all are functioning properly.
  3. Verify the power supply functionality, as follows:
    1. Disconnect AC power.
    2. Remove all internal power supply cables from the system board.
    3. Plug in AC power.
      • If the power supply fan spins, and the BIST LED illuminates, then the power supply is good. Replace the system board.
      • If the power supply fan does not spin, or the BIST LED does not illuminate, replace the power supply.

My laptop wont turn on or charge i bought a new charger and it still wont work how can i fix it?


When you connect the power adapter into the laptop, does the power LED light up? If not then -
The battery adapter or the adapter's power lead or the laptop's power socket could be faulty.
Check power adapter’s DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.
If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

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.

HP a820n No Power-up after City Power Failure


You have a bad power supply. It is not an expensive fix. Remember HP's take HP power supplies. When ordering either look on ebay for your model or order from part supplier.

Sounds like the Power Supply is bad likes its not able to power on itself. Best thing to do, try a different known good power supply and attach it to the motherboard, if you get the same symptom with the machine not powering on then its a bad motherboard. If the machine does power on then you know your original power supply is bad.
