Hey guys.

I have a Dell Precision T3500 and It worked great up until I took it apart for cleaning then put it back together, upon putting it back together, it wouldn't power on.

First test I did was using the built in feature on the back of the power supply. I just held the power supply button down and it ran the computer completely fine with the led a solid green and everything plugged in.
I learned about this feature from this video.

After that, I used the built in jump feature that clears the ram I believe when it the jumps the power on, learned about this from the online manual found here (page 2). It's just a little plastic piece you pull off of 2 pins. When off, the power button works, I can use it to it turn the computer on and off. As soon as I put the plastic piece back on the 2 pin jumper though, the power button no longer works. When I got the computer on, it didn't display any out of the ordinary led codes or beep codes, just the normal 2 beeps on startup. Something strange though is that the OS won't start, it fails every time, I don't know if the ram being cleared has anything to do with that.

Just need some guidance on where to go from here. I can buy a new control panel for the front power button for only 5 bucks on ebay but after using that NVRAM jumper, I don't know If I need a new one.

You most likely disconnected something while cleaning the inside of the computer.

 

Go back inside the computer and check all of your connections.  Pull all of the power and data connections one at a time and reconnect them.  Do the same with the RAM and any other cards.

I tried that earlier before the things listed above but in high hopes, tried it again and unfortunately I'm stuck in the same boat. :(

 

I'm still thinking it might be the control panel that the power button sits on because when it's all plugged in and the computer is off, it gives off a faint yellow light in the led that would usually shine green when the computer is on. It's almost like there's an issue there. What also drives me to think this is that when I unplugged one of the cables from the control panel, it was extremely hard to disconnect it because it must have not be disconnected for years and I had to really pull to get it disconnected.

That real hard pull could have accidentally broken an inside connection. I can relate, I've done that too in the past. Had to buy another part.

Yeah, I keep thinking that's the issue. I wish I had a spare part to test it.

 

I guess I'll just have to buy one and hope that it's the issue.

 

Do you think I should buy one with the cables for $12 or get one without the cables for $5?

 

You think it's possible for me to break the cable too, or is that unlikely?

The cable I had to give a hard pull on was the bigger one with the yellow handle.

Buy the one with cables -- your computing is important to you, throw just a few extra dollars and get the known good cabling  :)

If this does not resolve the problem please post the color of the power (on) button and if it is solid or blinking.

 

Also post which of the power buttons lights (1 - 4) are blinking.

Unfortunately, it didn't fix the issue.

 

Dc3, when I'm able to run it using the jumper feature, it powers on as it did before and the power button lights up green. The 1-4 lights do their little startup run through and after a second, 1-3 stay solid green.

 

Edit: What drives me crazy is that it runs and is fully functional when I use the jumper feature (on a hardware level).
