Open the case and check the connection between the case power button and the motherboard. unplug that connection and short out the pins on the mb. The computer should start up. If it doesn't, there is something wrong with the mobo. If it does, there is something wrong with the switch, or the connector wasn't tight.

Issue with power button in HP ProLiant ML370 G6 server


If i am not mistaken I belive that there are two power supplies, correct? what if you swap them? Or if you have a spare... I think that maybe either the button isn't working correctly or the power supply might have some issues...I also think there might be some LED lights on the power supplies themselves...check it out.

If a PC suddenly fails to boot properly, you should perform a hard reset as the first action. Performing the hard reset will correct many problems. If the computer still does not start properly, select your symptom from the list below to guide you to the recommended corrective actions.
  1. Disconnect all peripheral devices and remove all USB devices and SD media cards. You want to test the computer not the accessories!
  2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds to drain all residual power and restore default startup settings.
  3. Reconnect the AC power adapter (but do not insert the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a fan or other moving parts turning.
  4. If the computer does not start, the LED lights do not glow, and the display is black, you can perform one or more of the following actions to resolve the no power issue.
    • Verify the computer is receiving power from the AC adapter . Verify that the AC adapter is not damaged and is connected correctly to a working wall outlet plug. Verify AC power is connected to the system board by examining the AC adapter, wiring, and pin connection for damage. The keyboard LEDs will glow when AC power is connected to the system board. Damaged components, like the AC adapter or the pin in the power connector, may require an HP-certified repair.
    • Use a different AC power adapter . If you have access to a different AC adapter or power pack that is designed for the computer, connect it to the notebook and try to start the computer. If you own or have access to more than one notebook, verify that you are using the adapter which belongs to the notebook. CAUTION: Using a power adapter that does not meet the power requirements or has the wrong type of connector may damage the computer. On newer notebook models, connecting the wrong adapter to the notebook may cause the power LED lights to blink but not power the computer.
    • Remove the battery and boot on AC power only . A discharged or defective battery may prevent the AC adapter from supplying enough power to start the computer. To verify that power from the AC adapter is available for PC; remove the battery, connect AC power adapter, and press power button. If available, try using a different AC adapter, that is rated for the PC, and repeat this test.
    • Remove the AC adapter and boot on battery power only . A defective AC adapter may not charge the battery and prevent the computer from booting on battery power only. To verify battery power available for the PC; connect AC power adapter, allow battery to charge for 30 minutes or more, disconnect the power adapter and press power button. If available, try using a fully charged battery, of the same type, from another computer and repeat this test.
      • If LEDS do not glow and the fan or hard drive do not spin, battery may need to be replaced.
      • If tests of both the battery and the AC adapter fail, there may be a problem with system board requiring service by HP.
      • If LEDs glow and PC boots, the AC adapter may need to be replaced.
      • If LEDs glow, but PC does not boot go to LEDs glow, fan is heard, but display is black or blank section.

I found a way to eject the disk:
  1. Power off the PS3 on the main switch on the back of the console
  2. Press and hold the Eject button
  3. Turn on the main power switch
  4. The PS3 LED will go green and the fan will spin at max speed
  5. Wait a few seconds and press the eject button a couple of times, the disk should now eject
  6. watch the PS3 die after 30s or so…
This procedure did not fix my PS3 but at least I got my disk back before sending it to Sony for repair.

First of all when you switchon your PC, checkout whether your processor Fan is running. Because problem might be because of SMTP failure [Power Supply in your CPU] if its working fine and you are able to see LED glowing in *********** board, might be loose connection in your Hard disk cable.
Let me know this didn't help you out or if you need more info.

Internal led of ML350 server is glowing.......how do i resolve it?


Hi Franceso, plz specify
Is it powering ON ?
Which LED is glowing?
These leds are there on the front panel :

1 Power On/Standby button
2 System power LED
Green = Power on
Amber = System shut down, but power still applied
Off = No power

3 Internal health LED (Wave sign in BOX)
Green = Normal
Amber = System degraded. To identify the component in a degraded state, refer to system board LEDs.
Red = System critical. To identify the component in a critical state, refer to system board LEDs.
Off = Normal (when in standby mode)

4 External health LED (power supply)
Green = Normal
Amber = Power redundancy failure
Red = Critical power supply failure
5 NIC 1 activity LED Green = Network link
Flashing = Network link and activity
Off = No link to network.
6 UID LED Blue = Activated
Flashing = System remotely managed
Off = Deactivated
7 UID button

If it is Internal health led then any internal h/w issue is suspected.
If it is external health led then any power supply or power source related issue is suspected.
Also check the status of the server & its IML (Integrated Management Logs) in ilo (Integrated Lights Out ) if it is configured. (2nd RJ45 port in rear)

Also make sure the cabinet is properly closed.
