# No Monitor Boot Issue Fix for Q30900GE Series

Qotom Q30900GE 8x2.5Gbps mini PC fails to boot without a monitor? Here is the official fix for BIOS V13/V20. Disable CPU C-State in BIOS to solve the no-display boot problem permanently. 

### 1. Problem Description

Many users encounter a boot issue on the Qotom Q30900GE (8×2.5Gbps) mini PC: the device boots normally with a monitor connected, but **fails to power on or boot up without a monitor**. This error occurs on BIOS versions Q30900GE02.V13 and Q30900GE02.V20. Common BIOS adjustments cannot resolve the problem, affecting headless deployment for router, server and industrial control scenarios.

### 2. Root Cause

This is a BIOS power management compatibility issue instead of hardware failure. The CPU C-State power-saving mode is enabled by default. When no monitor is detected, the CPU enters deep sleep mode during POST, causing boot failure.

### 3. Official Solution (All BIOS Versions)

Disable the CPU C-State option in BIOS to fix the headless boot issue. No BIOS upgrade or hardware reset is required.

#### BIOS Setup Steps

1. Enter the BIOS interface during startup;

2. Go to **Advanced > Power > CPU Power**;

3. Locate the **C State** option and set it to **Disable**;

4. Press F10 to save changes and reboot the device.

### 4. Notes

1. After disabling C-State, the mini PC can boot normally in headless (no-monitor) mode, suitable for long-term unattended operation;

2. This setting slightly increases basic power consumption but **does not affect network performance, forwarding speed and device stability**;

3. If the problem persists, restore BIOS default settings and re-disable C-State.
