Why blinking yellow light and green light infront of cpu


Check if the signal cable for the display is connected and whether there is any kink that may break a wire inside the cable. If the circuit for display inside the computer is broken, most of the time you would hear beeping when turning on the computer.

I have a Dell Dimension E521. When I cut the power on everything comes on including the monitor, but the monitor will stay black. It does say something about power save hit any button but the screen


A solid green light means the computer is operating normally.

A solid yellow light indicates the power supply is operating normally but the computer is not processing data.

This could mean there is a problem with the CPu or another component on the motherboard.


((A blinking yellow light indicates the power supply is receiving power from the wall, but not functioning properly.
This generally means the power supply itself is bad and should be tested or replaced.))


A blinking green light means the computer is in standby mode.

You should consider visiting Dell Support and downloading the manual for your

your Dell computer. So use the LED power light codes if your Dell computer has them.

hope this helps

Screen will not come on hard drive light no light checked power supply is ok


Things to check:
  1. Power led on the front of the tower, it should be solid green when on. Flashing Amber is generally an indication of a bad power supply inside the tower
  2. Power LED Solid AMBER indicates system is not finishing the power on self test (POST) and you remove all connections from the tower except power and try turning on again. If no change, remove all PCI and PCI-E cards from system, try again, no change replace motherboard.
  3. On the back of the tower are 4 diagnostic LEDs near the ps2 ports marked ABCD, after the POST, during a normal boot the will flash in several sequences and with boot is finished all 4 should be green. If they stop an a different pattern, then that indicates a failure Yellow Yellow Green Green indicate bad RAM for example
  4. If the LEDs on front and back are Green then the system appears to be booting but the monitor display is not functional

Computer it doesn,t turn on just the yellow light blink


Generally this indicates a failed power supply. There is also a slim chance that the motherboard could be bad, but 85% of the time, it is the power supply... Excerpt from the Service Manual:

Blinking amber:
- A power supply or system board failure has occurred.
- Check the diagnostic lights to see if the specific problem is identified. Also, see "Power Problems" in your computer Owner's Manual.

Link to troubleshooting section of service manual.

Computer will not turn on


  • Blinking Amber/yellow: Initial state of LED at power up.
    Indicates system has power, but the POWER_GOOD signal is not yet active.
    If the hard drive LED is off, it is probable that the power supply needs to be replaced.
    If the hard drive LED is on, it is probable that an onboard regulator or VRM has failed.

Did you see the battery in the motherboard, near the battery there is 3 pins in which the two pins inserted by a jumper..to reset the setting remove the jumper and put it in the next considering the center pin. either in left or right connection. and then switch on the pc. this will reset the setting.

Powerbutton flashing yellow


If the main power button LED is flashing or solid yellow, this could indicate a hardware problem.

 

Was it running good before?

 

Are the diagnostic LED lights all green?

 

Here is what dell says:

 

If the power light is blinking amber  —

 The computer is receiving electrical power, but an internal power problem might exist.

  • Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).
  • Ensure that the processor power cable is securely connected to the system board.

Do you remember what the BSOD said?
