Hardware diagnostics
Your computer supports the hardware diagnostics function. This function enables your computer to monitor
some hardware components in real time for potential issues that might not be easily detectable during
normal use. When the computer detects an issue or error, the four-digit diagnostic display on the front of the
computer displays text and a numerical error code. See “Locating connectors, controls, and indicators on
the front of your computer” on page 28.
For information about the issue or error, do the following:
1. Connect either of the following devices to the diagnostic USB connector on the front of the computer:
• A USB key
• An Android
TM
device with the Lenovo Mobile Diagnostic application installed
See “Locating connectors, controls, and indicators on the front of your computer” on page 28.
2. Wait about 10 to 15 seconds for the diagnostic data to transfer from the computer to the USB device.
During the data transfer, the four-digit diagnostic display displays “File Copy”. When the data transfer
finishes, the four-digit diagnostic display displays “File Copy Done”.
Note: Diagnostic data is available for transfer through the diagnostic USB connector only when text
and a numerical error code is displayed on the four-digit diagnostic display. In normal conditions, the
diagnostic USB connector functions as a standard USB 3.0 connector.
3. Depending on whether you are using a USB key or an Android device (such as a smartphone), do
one of the following:
• If you are using a USB key, go to http://www.lenovo.com/support for information about how to
read the error data on the USB key.
• If you are using an Android device with the Lenovo Mobile Diagnostic application installed, open the
application for details about the error.
For more information about how to use the diagnostic USB connector on your computer, decipher the error
codes, or use the Lenovo Mobile Diagnostic application, go to http://www.lenovo.com/support.
The hardware diagnostic function is enabled on your computer by default. To disable the function, do
the following:
1. Start the Setup Utility program. See “Starting the Setup Utility program” on page 65.
2. From the Setup Utility program main menu, select Advanced ➙ Diagnostic function , and then press
Enter.
