Hello there,
Could you please send us a picture of SN on the bottom of the PC and a picture of purchase record ?
so that I can confirm the model of your machine.
you can try the following method,
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. |
