The device runs normally with no error prompts, but all connecting cables must be unplugged before powering on to boot successfully. Current temporary workaround: Unplug all wires, wait around 20 seconds, only connect the power cord to start the machine; reconnect remaining cables after the system fully boots for normal use. What is the root cause?
The core issue is the unit cannot boot with any external devices connected at startup. Two common causes and corresponding solutions are listed below:
- Excessive power draw from external USB devices USB-A ports follow the 5V 2A power supply standard. If an attached USB peripheral draws power exceeding the port’s rated limit, the host will fail to boot. Troubleshooting method: Plug in peripherals one by one after boot to identify the faulty device. Solution: Equip the high-power peripheral with an independent power supply, or only connect it after the system finishes booting.
- Abnormal BIOS USB power supply parameters Upgrade the host BIOS to the official latest version to resolve this compatibility bug.
