No power on problem: When the device won't power on and the power indicator doesn't light up, make sure the power supply is connected and working properly. If your CPU fan is installed correctly, you can also determine whether the power supply is working properly by judging whether the fan can work properly. 1. Confirm the power supply of the power adapter a. Please check the connection of the power cord and whether the socket is plugged in as shown in the figure below. If there is a main power switch on the extension cord, please make sure it is on state. b. Replacing the extension cord and socket will help solve the problem. Verify that the motherboard power supply is properly connected: 1. Make sure the power adapter's power cord is properly plugged into the ATX power connector. The motherboard may contain 24 pin EATXPWR and 8 pin EATX12V, make sure that both 8 pin EATX12V and 24 pin EATXPWR are connected to the power adapter. The location and number of power connectors may vary from model to model, some motherboards may contain 24 pin EATXPWR and 4 pin EATX12V, both connectors should be linked to the power adapter Does not power on: When the fan and Q LED indicator Q CODE do not respond when the power button is pressed to start the computer, please follow the instructions below to troubleshoot the problem 1. Follow the above Verify that the power adapter is properly plugged into the ATX power connector. 2. Keep the CPU, CPU cooler fan and a separate RAM display on the motherboard. Remove all USB devices and external cards from the motherboard, including mice, keyboards, card readers, flash drives, external hard drives and external PCIE cards, etc. Remove all cables from the motherboard, including network cables, audio cables and display cables (HD Multimedia Interface, VGA, DVI, DP). Then try to turn on the computer, if it turns on properly maybe the problem comes from the external devices removed. Reconnect the external devices one by one until you determine which external device or cable is causing the problem. 3. Try to clear the CMOS. Package List 1 x Motherboard 1 x SATA Cable 1 x Bezel
