Dell laptops have issues with the power regulation chip. What you need to do is pull the back cover off and unplug both the main battery and the CMOS battery. You need to be very very careful removing the CMOS battery. Do not pull the battery out by the wires. I find it’s best to use a plastic pry tool of some form, whether it be a spudger, old credit card or some other thin semi-semi blunt plastic tool. If you rock the two sides back and forth then push out the connector down the center, it will come out. The CMOS battery looks like this: https://guide-images.cdn.ifixit.com/igi/rWTpWLLvSdZ36TQU.large Once you have both batteries unplugged, hold the power button for 60 seconds. Yes, really, 60 seconds. Plug both batteries back in and plug in the charger, then attempt to turn the laptop on. If all went well, the CPU fan should spin over a few times before the machine finally boots back up. Put the cover back on and you’re done. Source: I’ve been working in IT Support/Management with Dell as our main vendor for the last 12 years.

I don't even see any lights on. Typically something lights up to acknowledge power is coming in. Could be charging port. Could be battery. Could be board.

r/buildapc on Reddit: Dell 5680 PSU Upgraded But Still Won’t Power Up

January 9, 2023 -

Hi everyone and thank you in advance for the help.

I had a recent power surge that tripped my breaker. Happened before and my PC is plugged into a surge protector so I reset everything but found my PC wouldn’t turn on.

I completed the BIST test per the dell forum and the PSU failed. I had a green light but the fan wouldn’t turn on with and without components plugged in.

Simple problem, right? Just upgrade the PSU.

I did some research on the dell forums and settled on a Cosair RM750. Snagged one from micro center, hooked it all up annnd… no power. Zero signs of life.

I’ve rechecked my cables, tried multiple outlets, and I cannot figure out what is wrong.

I’ve settled on a couple of other options to try tomorrow:

Change the CMOS battery
Check and potentially replace the power button switch/cord (no idea if this would be the issue but I’m desperate)
Call dell (ugh)
Take it to micro center and have them run some diagnostics to see if my motherboard is fried from the surge :/

Does anyone have any tips or options to try? I’d really appreciate any help.

Update: Tested the Corsair RM750 with a paper clip and it passed. Fan turned. Brand new so not a surprise. Went through and turned it on with individual components plugged in. Nothing turning on. Started with the motherboard, so I’m thinking it’s fried.

USB-C External Monitor No Longer Working on Precision 5680 | DELL Technologies

September 4, 2024 - I have the exact same problem on my Dell Precision 5680. BIOS 1.13.0, the same problem under both Linux and Windows. Essentially, if you plug an external display into any of the USB-C ports, it can only output a display signal if the external device isn't also being powered from the laptop. For example - plugging in an external monitor with just a USB-C cable will power the monitor on, but you won't get a display signal.

r/Dell on Reddit: Did I just break my new work computer? Precision 5680

September 24, 2024 -

Just got a brand new Precision 5680 from my employer. There was a little tab between the keyboard and screen that I thought was a thing that needed to be ripped out. You can see the remnants in the images. I ripped it out and now the computer won’t start. First the display went - I could still see my work on my second monitor. Now it won’t start at all. Coincidence or did I just damage something essential?

That’s a video cable and yes, you damaged something critical.

2 of 5

That cable shouldn’t have been accessible or visible in the first place, but yeah ya broke it. The cable itself can be replaced but that thing is probably going back to Dell.

@Christina Matos · What colour is the LED in the Power button when you press it only i.e. without the BIST key as well, to start up the PC? · Try disconnecting the power cord from the PSU and then holding the Power button operated for a full 30 seconds and then release it. Reconnect the power cord to the PSU and then try to turn on the PC using the power button only.

r/Dell on Reddit: Dell Inspiron 5680 - not booting

January 29, 2023 -

Hi Everyone,

I am looking to find out where the hardware failure is on my PC. I was playing video game with my friends, and the PC suddenly crashed. When I hit the power button, it doesn't turn. I researched online, and did the BIST test. The LED is solid green, and the fans are running and the PC makes noise similar to starting up, however, the PC won't boot. Nothing on screen. Further research leads me to believe that I may have to replace the PSU but how can I test this? Also, is there a way to know it's not motherboard failure?

Thank you!

Ok, so I had a similar issue with an old Optiplex. I fixed it by removing all but one RAM stick, installing a different CPU, and updating the BIOS. Don’t ask me why or how it fixed it, I have no f***ing idea, it just worked XD

r/Dell on Reddit: Precision 5680 - Battery/Charger Priorities & Intel VPU Crashing

February 24, 2026 -

Dear Redittor, I just scored a used Dell Precision 5680 for USD615 on FB Marketplace.

Specs:

CPU: i7-13700H
RAM: 32GB
GPU: RTX A1000 (6GB)
NPU: Intel Movidius 3700VC VPU
Power: 100W Charger (Current)

The Catch: The Service Tag isn't recognized, though BIOS shows no Asset Tag or Absolute activation. The battery health is reported as "Fair" and hold a charge for about 1.5hr from browsing web.

My Questions:

Charger vs. Battery: I can get a new battery or the 165W charger for $70 each. I can only afford one right now. Is the 165W charger necessary? I'm worried the 100W brick causes "battery drain under load," which might kill the new battery faster. And I heard that only the 165W charger will provide enough power for full performance. Which should I prioritize?
Intel VPU Crashing: After a clean Win11 install, the VPU shows in Task Manager, but launching the camera or Studio Effects causes crash. SupportAssist and manual installation fails to install the “Intel-2D-Imaging-MCU-Visual-Sensing-Controller” driver. Any workarounds?
The Deal: Did I do okay for $615? Planning to use it for study IT courses and light AI work (hence pick the 6GB VRAM).

Top answer

From what I‘m seeing, prioritizing the adapter will allow you achieve full CPU and GPU performance, and you won’t be stressing the battery or VRMs. As far as the VPU crashing, you would want to try download the official Dell Precision 5680 Win11 Driver Pack , boot into Safe Mode, remove all Intel imaging and video drivers with DDU, then install the Dell camera and VPU driver before any GPU or Iris drivers. Reboot afterward to finalize the fix. It seems like you got a good deal, hope you get many years out of this system!
