Dell Desktop: Dell Optiplex 3020 blinking orange light

Sat, 15 Nov 2025 23:18:10 -0700

Dell optiplex 3020 started rebooting randomly for some days and then shut down by itself while booting up and started showing blinking orange light. When put in sunlight for some time, it starts normally but shuts down by itself before even reaching lock screen and again starts showing orange light again.

Dell Dimension 3000: PC started to smoke after CPU install

Wed, 18 Sep 2024 13:42:47 -0700

I had removed the CPU from my pc, it was working fine before I removed it. When I reinstalled it and booted it up, however, the pc power light and diagnostic lights all shut off, but the hard drive light and fans were still on, like if the pc was half off, and I couldn't shut it down through the power button. Since the cover was off, I managed to smell a little bit of smoke. I immediately unplugged the pc once I smelled the smoke. When I looked with a flashlight, there were no signs of damage or burning on the motherboard. I traced the smell, which didn't go away, and figured out it had came from the power supply. I couldn't see any burnt components, but the fan was really dusty, so that could be the issue. Please let me know if you had any suggestions.

Dell Desktop: What is wrong with my Dell OptiPlex 3020 power adapter (Solved)

Tue, 02 Apr 2024 16:35:19 -0700

I turned on my Dell OptiPlex 3020 this morning and I get a BIOS message. It says that the power adapter I am using is not factory, although it is. Now my computers runs so slow (crashed twice while trying to write this question). I don't know if this helps but my power brick light is green. The computer is only 1 and a 1/2 years old. Here are some images of what I am talking about

Thanks in advance

Edit: The power adapter is original to the system

Dell Desktop: No HDMI signal on startup after shutdown

Wed, 10 Nov 2021 06:42:14 -0700

I have an unmodified dell XPS 8700. Late last night the fan went on full speed so I forced a shutdown so I could sleep. This morning the computer won’t start, just giving a no HDMI signal error. After shutting down, removing all power and peripherals for 10 minutes then starting again the computer managed to display a grey screen but couldn’t start. The lights and fans are on but I can’t seem to get any further.
any advice appreciated. The only other suggestions I can find suggest buying new parts which I don’t have time to do so I want a second opinion before buying anything.

Dell Dimension 3000: replacing the CPU holder

Sun, 07 May 2017 22:29:34 -0700

The square frame that is used to help hold done the CPU. Two corners have broken off and the clips will not connect so the processor is not held in place. Where can I find the part?

Here are the pictures - at least they show up in the preview!

Dell Optiplex 7090 Micro: Dell OptiPlex 7090 Micro SMD power button sourcing?

Fri, 20 Feb 2026 20:02:27 -0700

I have a Dell OptiPlex 7090 Micro on my bench. It has intermittent response to the power button. Upon investigation I found the plastic shroud that extends out from the button is broken in half and part missing (great design from dell...) basically the mechanical component that gets pressed is a hollow tube surrounding the power status LED instead of, say, a solid tube of clear plastic.

Well, anyway. I'm looking to source a replacement SMD power button so I can solder on a new one, but I'm having problems sourcing it besides the old 'look for a whole broken PC of the same model as a donor' route. Seems wasteful, and since it is a relatively new model, also expensive. I want to make sure to get an exact replacement as it needs to have the power LED in the center of the button. See pictures for reference. Thank you for taking a look!

@ulees I want to put a new graphics card in this and I’m not sure what graphics card will work. So does it matter what graphics card I put in it? Will any graphics card work? It currently has its original card installed and I’d like to put a MSI GeForce GT 730 2GB 64bit GDDR5 in it. I know that it’s PCIE 2.0 but what I’ve found is that it will work in PCIE 1.x.
