XPS 8930 power issue, how to diagnose?
Hello everyone, tried to fire up my PC today and got nothing on the monitor.
Tried unplugging the power and plugging into another known good outlet, no luck.
After power cycling it a few times I noticed that when I turn it on the LED on the power button blinks yellow once the turns a very faint white and stays like that. No boot screen or anything. The fan also comes on when i power it on and the green LED by the computers power supply turns on when I press the BIST button. Any troubleshooting recommendations?
Thanks@!

You don't even see the Dell splash screen when you power on?
Can you test this monitor and its cable on a different PC, or a known working monitor and its cable on this PC?
If you're using a power strip and/or surge protector, remove them and plug PC and monitor directly into working outlets.
Do you have an add-in video card (NVidia or AMD, and exact model?) or only onboard Intel Graphics? And if you have an add-in video card, the monitor should be connected to the card, not to one of the onboard Intel Graphics ports.
Which fan comes on when you press power button, CPU fan, case fan or PSU fan?
Does the PSU fan turn on and spin correctly when you press the PSU test button? Even if the PSU LED turns green, if the PSU fan doesn't spin, the PSU has failed. Read the PSU BIST instructions, here.
When was last time you replaced the motherboard battery?

Looks like I was plugged into the Intel Graphics ports instead of the video card. PC was working fine before but I guess it decided it didn't like that. I am now at least seeing the troubleshooting boot screen. Currently running startup repair. Motherboard battery had never been replaced. Am i due for a new one?

Possible a Windows update did something that caused problems when using the onboard Intel Graphics port instead of the GPU.
Can't hurt to replace the battery, especially if it's more than ~3 years old. It's only ~$3, and if nothing else, you've ruled the battery out as the cause....
Hope the startup repair fixes the problem! Post back and let us know...

Startup repair scan didn’t see anything wrong with the hardware but I had to run a recent restore point to get my PC working again. Luckily I had a semi recent recovery point. All in all not sure what triggered this but PC is functional again so I’ll take the W and probably replace the PS as you suggested.
Really appreciate the troubleshooting help!

Glad you got it working again.
I didn't suggest replacing the PSU, only to follow the BIST instructions fully to see if the PSU was the issue.
Startup repair doesn't check hardware. It only checks Windows files and config. So if a System Restore resolved the problem, that sounds -to me- like you had a failed/corrupted Windows update.
Once the system is fully back up-to-date, suggest you use imaging software (eg, Macrium Reflect, Aconis etc) to create a backup image on a regular basis and save it on an external HDD, just in case...
