My dell T7810 PSU green light on and CD light is on but on off switch do nothing after press. In remove all memory, Disks and video card. change Cmos battery also but nothing happen.
For starters, run the BIST test on the power supply. Doesn't look like this Precision has a PSU self-test button, so follow instructions for PCs "...without the button on the PSU."
Possible the intrusion switch or the power button module failed... ?
