    Is amber power button steady or blinking?

    When was last time you replaced the motherboard battery?

    You could try clearing BIOS:

    1. Reboot and immediately press F2 to open BIOS setup
    2. Copy down all current BIOS settings
    3. Power off, unplug
    4. Press/hold power button for ~15 sec
    5. Open case and remove motherboard battery (check Service Manual for details)
    6. Press/hold power button for ~30 sec
    7. Install a fresh battery (CR2032 3-volt coin cell battery)
    8. Close up and connect mouse, monitor and keyboard
    9. Reboot

    If you can't get into BIOS setup by pressing F2 at boot, just start with #3, above.

    And since this is a workstation, you might get better responses in the Precision Workstation forum.

    Hi,

    I have the same problem with Dell T3400 PC. The orange light in my PC's power button is steady.

    Only the orange light is on in the power button, or just the CD-ROM is running nothing else, and the fan is very loud. I have tried everything, what do you think is the reason for this problem? What percentage of CMOS battery can solve this problem now? Just check by installing a new CMOS battery.

    Please help me.

    Thank you

    @raoatiq.cw  - Don't understand..Did you -or not- replace the motherboard battery and clear BIOS?

    What color are the four diagnostic LEDs on front panel when it won't boot? Look up error codes here.
