How to disable auto launch of Enhanced Pre-Boot System Assessment (ePSA) on boot
Hi,
I bought a XPS 8900 a couple years ago and last week I replaced its case with a new bigger one.
Once I did this, Enhanced Pre-Boot System Assessment (ePSA) starts launching on every boot to complain about Power button. When I worked around of the power button issue, it start complaining about rear FAN.
All these diagnostics are false positive.
How can I completely disable ePSA?

You can't these are part of the bios. People also replace the Dell fans and heatsinks etc with non dell units and get errors. These won't go away either.

I don't think there is a way around it. The complaint about fans, etc have been around in Dells for many years. Dell uses custom fans with sensors on them that the system "sees" and if not an error is flagged.
