Power button not working on desktop

This question is not answered

I have a Dell computer I purchased in 2005.  It has worked great and I have had no issues.  All of this sudden, this morning, the power button won't work.  I push it and push it and nothing but a yellow flashing light (the button flashes yellow).  I unplugged everything and plugged it all back in twice and finally got the power button to work.  Midday, I had to shut of the unit for a bit-when I came back to start it again, had the same issue, except this time no blinking light.  Did the same thing, and finally got it to power up.  ANyone ese had this problem or have any ideas why this is happening???

  • Hi, mightyamazon67:

    Is this a Dimension 4600 or 4700?

  • I don't know.  How would I find that out????

  • mightyamazon67,
    There should be a ring around the computer's power button that has its model number printed on it.

  • no-there isn't anything printed around the power button

  • It's going to be difficult to help you without even knowing the model of your computer. Did you buy it new from Dell in 2005 or used elsewhere? Is the system black or beige?

    Does this help???

  • The silver color narrows it down a little but there are still too many Dimension models to tell what you have based on that. If the model number isn't on a ring around the power button then there should be a small badge somewhere on the front of your tower that has the model number engraved on it. If you can't locate this you'll need to find the service tag sticker of that machine and type it in on the product support page of support.dell.com using the computer you're on now. This will cause the system model to be displayed on your screen then we can go from there.

  • Hi,

    I am having the same problem with my Dell Dimension 4700.

    My computer (Dell Dimension 4700c) is having problems starting. the power button flashes yellow. I've tried everything in Dell troubleshooting...besides uploading Master Boot  Record fixer, in which it won't download.  Tried to update drivers also, Dell download manager doesn't work, removed it. Now it's just asking me if I want to install it.

    If anyone can help me, please.

    Is the power button LED, solid green, blinking green, solid amber, blinking amber?

    Check the sequence of the DIAGNOSTIC LIGHTS on the back panel.

    Are there any 'Beeps', or error messages, does the power supply fan work?

    Bev.

  • I have the Dell Vostro 260. The power button is not working. At first, I thought the button issue so I bought the supply and changed it. However, it's not the button issue at all. I saw the solid green light in the back of power supply. I saw solid amber light in the motherboard. There was no beep sound and the fan was not working when I tried to press the power button. I also checked everything like power supply fully plugged to the motherboard but it's still not working from the power button. Do you know what other issues to check. I bought this PC in 2010.

  • It would be helpful if you created a new thread for this issue.
