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 diagnostic indicator on the front of
the computer is illuminated or blinks. 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 Workstation Diagnostics app 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 diagnostic indicator blinks quickly. When the data transfer finishes, the
indicator stops blinking and stays on.
Note: Diagnostic data is available for transfer through the diagnostic USB connector only when the
diagnostic indicator is illuminated or blinks at an error detection. 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://support.lenovo.com/workstation_diagnostics for information
about how to read the error data on the USB key.
• If you are using an Android device with the Lenovo Workstation Diagnostics app installed, open the
application for details about the error. For more information on the Lenovo Workstation Diagnostics
app, go to http://www.thinkworkstationsoftware.com/diags
For more information about how to use the diagnostic USB connector on your computer,

The hardware diagnostic function is enabled on your computer by default. To disable the function, do
the following:
