5 USB 3.0 connector (for connecting to the computer)
Using the I/O box
When you use the I/O box with the ThinkStation® tiny computer, note the following:
• The I/O box supports a maximum current rating of 5 A. It is recommended that you connect low-current
devices to the I/O box and connect high-current devices directly to the ThinkStation tiny computer to
ensure the best performance of the devices.
• The USB 2.0 connectors and USB 3.0 connectors on the I/O box provide a current of 500 mA and 900 mA
current, respectively. When you connect a high-current storage drive to only one USB connector, the
system might not recognize the device. You can connect the storage drive to two USB connectors on the
I/O box.
• The serial connector does not support hot swapping. Do not connect a device to the connector or remove
a device from the connector while the system is running.
• The connectors on the I/O box cannot be enabled or disabled individually. To enable or disable any of the
connectors on the I/O box, enable or disable the USB connectors on the rear of the computer.
© Copyright Lenovo 2017, 2018 5
• The I/O box enables you to wake up the computer from standby mode through operations on devices
connected to the I/O box connectors.

Chapter 3. Connecting to other devices
Attaching a Kensington-style cable lock
You can use a Kensington-style cable lock to secure your computer to a desk, table, or other non-permanent
fixture. The cable lock connects to the security-lock slot at the rear of your computer. Depending on the type
selected, the cable lock can be operated with a key or combination. The cable lock also locks the buttons
used to open the computer cover. This is the same type of lock used with many notebook computers. You
can order such a cable lock directly from Lenovo by searching for Kensington at:
https://support.lenovo.com
Figure 5. Kensington-style cable lock
Connecting to a Tiny-In-One monitor
Note: When installing the P320 Tiny computer to the Tiny-In-One (TIO) monitor, ensure that you use the
135W ac power adapter that comes with the computer.
The P320 Tiny computer works with its integrated graphics card by default when it is installed to the TIO
monitor. You can turn on or turn off the computer by pressing the power button on the TIO monitor. Any
other devices connected to TIO monitor function the same as they are connected to the computer.
To switch the primary video display output from the integrated graphics card to the discrete graphics card,
do the following:
1. Turn on or restart your computer.
2. Before Windows starts up, repeatedly press and release F1 or Fn+F1 (depending on the keyboard
settings) until the Setup Utility program opens. If a BIOS password has been set, enter the correct
password when prompted.
3. Locate the Select Active Video submenu and select PEG. Then press F10 to save changes and exit.
4. Connect the discrete-graphic-card connector on the computer with the DisplayPort or HDMI connector
of the TIO monitor using an applicable dongle.
© Copyright Lenovo 2017, 2018 7
5. Press the mode-switching button on the TIO monitor to change from the TIO mode to the DP mode or
HDMI mode.
When the computer works with the discrete graphics card, pressing the power button on the TIO monitor
only turns on or turns off the TIO monitor. Devices connected to the TIO monitor do not function the same as
they are connected to the computer.
Supported TIO monitor models:
• Tiny-in-One 23 (MT: 10DQ)
• Tiny-in-One 22 (MT: 10LK)
• Tiny-in-One 24 (MT: 10LL)

Chapter 5. Replacing hardware
This chapter provides instructions on how to replace hardware for your computer.
Before replacing hardware
Attention: Do not open your computer or attempt any repairs before reading the Important Product Information
Guide.
Read these notes before replacing hardware:
• Some of the hardware components explained in this manual are optional.
• Use computer components provided only by Lenovo.
• When installing or replacing an option, use the appropriate instructions explained in this manual along with
the instructions that come with the option.
• In most areas of the world, Lenovo requires the return of defective CRUs (Customer Replaceable Units).
Information about this will come with the CRU or will come a few days after the CRU arrives.
Handling static-sensitive devices
Do not open the static-protective package containing the new component until the defective component has
been removed and you are ready to install the new component. Static electricity, although harmless to you,
can seriously damage computer components.
When you handle parts and other computer components, take these precautions to avoid static damage:
• Limit your movement. Movement can cause static electricity to build up around you.
• Always handle parts and other computer components carefully. Handle PCI/PCI-Express cards, memory
modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.
• Prevent others from touching the parts and other computer components.
• Touch the static-protective package containing the part to a metal expansion-slot cover or other
unpainted metal surface on the computer for at least two seconds. This reduces static electricity from the
package and your body before you install or replace a new part.
• When possible, remove the new part from the static-protective package, and install it directly in the
computer without setting the part down. When this is not possible, place the static-protective package
that the part came in on a smooth, level surface and place the part on the package.
• Do not place the part on the computer cover or other metal surface.
Knowing replaceable parts
Customer-Replaceable Units (CRUs)
CRUs are computer parts that a user can upgrade or replace. There are two types of CRUs: self-service and
optional-service.
• Self-service CRUs:
You can install self-service CRUs easily. These CRUs might be standalone, latched, or secured by up to
two screws.
© Copyright Lenovo 2017, 2018 11
Examples of self-service CRUs include the keyboard, mouse, any USB device, and the power cord. Other
self-service CRUs might include memory modules, adapter cards, hard disk drives, and optical drives.
Note: Users are responsible for replacing all self-service CRUs.
• Optional-service CRUs:
Handling optional-service CRUs requires some technical skills and simple tools (such as a screwdriver).
These CRUs are isolated parts within the computer. They are usually concealed by an access panel that is
secured by more than two screws. You must remove the screws and panel to access the specific CRU.
Optional-service CRUs can be removed and installed by users or, during the warranty period, by a Lenovo
service technician.
Field-Replaceable Units (FRUs)
FRUs are computer parts that a trained technician can upgrade or replace. For detailed FRU information,
such as the FRU part numbers and supported computer models, go to:
https://support.lenovo.com/partslookup
CRUs and FRUs locations
Refer to the following illustrations to check the locations of CRUs and FRUs within the computer.
Notes:
• Some of the following parts might look different from the one illustrated.
• Some of the following parts are optional on some models.

The instructions on how to install or replace a M.2 solid-state drive also apply to the Intel Optane memory.
Before replacing the Intel Optane memory, ensure that you disable the Intel Optane memory from the Intel
Rapid Storage Technology (Intel RST) Console. Otherwise, all data on the storage drive will be lost.
Note: The instructions on how to replace an M.2 storage drive also apply to the Intel
®
Optane™ memory.
