I refurbished some outdated HP Desktop computers from our business for private use and reinstalled them on Win10. On anElitedesk 8200 with I5 CPU the Power LED is now permanently red, before it was green. I already swapped the power supply, but no change. There are 2 hard disks and one DVD drive running in the machine. Everything works fine, Windows is running and there's no visual lack in performance. Do I have to worry or can I just continue using the computer ? In another thread I found permanent red LED means power supply, mainboard or cpu problem.
I also ran a diagnostic tool named HW Monitor and values seem normal to me (CPU temperature etc).
Thanks in advance for any advice and sorry for my english.

it's me again. I now ran HP PC Hardware Diagnostics Tool and all tests were successful. I also disassembled the PC and checked the fans. All (power supply, CPU fan and front fan) are running. I also plugged off all drives temporarily. Everything seems ok except the color of the LED. I also restored BIOS to default values. Does anyone have an idea?

the elite 8200/8300 uses the exact same motherboards as the 6200/6300 Pro SFF (only diff is the 8300 has two x16 pci-e slots)
both use the same bios
i have a 6300 pro sff here that i did the win 10 update on and the power light stays green with the stock factory cpu and also with the upgraded q9550s cpu
do note that the 9550 cpu is available in two different versions the high power (95 watt) one and a low power one (65 watt)
the "S" suffix denotes the low power 65 watt cpu
if you installed the high power version of the 9550 this may be the reason for the red light
