Hardware Failure Coverage

• Damage caused by abnormal power adapter output.

• Manufacturing defects (such as soldering problems/circuit board short circuits).

• Problems with the Wi-Fi network card.

Regarding your question about heat dissipation, please note the following: This mini PC is designed with portability as its core advantage, resulting in a compact internal space. Therefore, under high loads (such as demanding games or multitasking), its heat dissipation capacity is slightly less than that of a traditional desktop PC. This is a common characteristic of mini PCs.

To achieve better heat dissipation, we recommend the following when using it:

• Place the device on a well-ventilated desktop, avoiding placing it in a closed cabinet or where it is obstructed by clutter;

• Regularly clean the dust from the vents and fans;

• If needed, consider using it with a small cooling pad.

I want you to make two attempts. If it still can't be solved, we will help you with after-sales:

• If you have extra memory, you can try replacing it. If not, you can also remove the memory, gently wipe the metal edge with an eraser, plug it into the PC again, and try to boot.

• In the shutdown state, insert a sharp object into the CMOS, hold it for 30 seconds, and then restart the computer to try again.

This appears to be a system issue. The system has crashed. Do not suddenly power off the system during use. This may corrupt system files and cause an automatic repair screen to appear.

• Finally, click the Restart button. The computer will directly enter the BIOS/UEFI settings interface upon the next startup.

Method 2: Entering via a key during startup

• Completely shut down the computer.

• After pressing the power button to turn it on, immediately begin rapidly and continuously pressing the Delete key (or F2, F10, or Esc key on some brands of computers).
