Q&A：
Q1. How to confirm the motherboard supports Q-LED indicator?

A1: You can check by the following three ways：
Method a. Check for the Q-LED indicator on the Motherboard, which is usually near the 24pin
power supply interface or memory slot of the motherboard (as shown in the picture below).
For some older models, such as Z97-mark_ S, Q-LED light will be next to corresponding slot, as
shown in below, The VGA_LED light is next to the PCIE slot, which is also applicable to the
above troubleshooting steps
Method b. Enter into ASUS Official website to check if your model support ASUS Q-LED

1) Click , then input your model name (Ex: ROG MAXIMUS IX FORMULA)
2) Click [Specifications], find [Special Features]- [ASUS Q-Design], check if [ASUS Q-LED] is
supported as shown below.
Method c. Enter ASUS Support-Center to download user manual to check if your model supports
ASUS Q-LED
download user manual
1) Input your model name (Ex: ROG MAXIMUS IX FORMULA), click [Manual & Document]

2) Click [Manual], find MAXIMUS IX FORMULA BIOS Manual(English), then click
[download]

Find [Special Features] - [ASUS Q-Design], check if [Q-LED] is supported as shown below

Q2: What to do if Q-LED troubleshooting can't solve your problem?
A2: Please try to clear CMOS, you can refer to: How to Clear CMOS

1. Please ensure microphone is connected to desktop pink hole.
2. Please ensure whether you've correctly installed driver or update the latest driver.
3. Enter "Control Panel"->"Ease of Access"->"Speech Recognition", choose "Set up microphone"
After you enter microphone installation wizard, follow the instruction to test.

No Power on
When the computer is unable to boot and the power indicator is OFF, please check that the
power supply is properly connected and can normally work. If you have correctly installed the
CPU Fan, you can make sure the power supply is normal or not by judging the CPU fan works
normally or innormally.
1. Check the power of the power supply

a. Please check the connection of the power cord and electric socket are well connected as shown
below. If there is a main power switch on the extension cord, please make sure it is switched on.
b. Replacing the extension cord and electric socket may be helpful to eliminate the problem.
2. Check the power of the Motherboard
Confirm the power cable of power supply is correctly connected to ATX power connectors.
Some motherboard may contain 24-pin EATXPWR and 4-pin EATX12V, both connectors
should be connected to the power supply.
(Model name of photo below is B150M-A)

Others may contain 24-pin EATXPWR and 8-pin EATX12V, make sure to connect 8-pin
EATX12V and 24-pin EATXPWR to the power supply. The position and quantity of power

connectors used may differ from model to model. Please refer to the user manual for more
details. (Model name of photo below is ROG ZENITH II)

No Boot
When you press the power button to power on the computer, the fan and Q-LED indicators/Q-
CODE have no response, please follow below instructions to troubleshoot :
1. Follow check the power of the motherboard troubleshooting steps to confirm whether the
power cable of power supply is connected to ATX power connectors correctly.
2. Keep the CPU, CPU radiator fan and a single RAM memory on the motherboard. Remove all
the USB devices and external cards from the Motherboard including the mouse, keyboard, card
reader, flash drives, external hard drives, external PCI-E Cards and etc. Remove all the cables
connected to the Motherboard including LAN cables, audio cables, and monitor cables
(HDMI/VGA/DVI/DP). Then try to boot the computer. If it can be powered on normally, the
problem may be one or more of the external devices. Re-connect the external devices one by one
until you find which external device or cable causes the issue.
3. Try to power off，then refer to clear CMOS FAQ: How to Clear CMOS
No Display
If the computer can power on, but there's no display on the monitor, please try the following
steps to troubleshoot:
1. Enter ASUS Download-Center to check if your CPU is in QVL list for compatibility.
a. Input your model name (Ex: ROG CROSSHAIR VII HERO), click [CPU/Memory Support]
