There is a small hole for CLR CMOS on the front of the machine, please insert a pin for 15 seconds after unplugging the power and HDMI cable, then turn it on to check whether it can be used normally.
And can the LED indicator of the power supply light up?
Looking forward your reply.
Have a nice day!
tried everything CMOS reset, battery reset, with ssd, without ssd, with ram, without ram. No picture, tried different cable, different monitors. Fan is not spinning. I also have old bottom cover (without holes).
