The USB Type-C connector on the left side of the computer with
a USB-PD icon next to it conforms to the Power Delivery specification.
If you did not carry the included ac power adapter with your computer,
you have the option of using a qualified USB Type-C charger (purchased
separately) that is also Power Delivery compliant to charge the computer
in sleep or powered-off state. Lenovo branded USB Type-C chargers
with the following listed maximum ratings are tested to work with
the computer. Chargers of other brands with the same ratings should
also work but are not thoroughly tested.

The left USB Type-C connector is not designed as the primary power
input connector. When the computer is operating, the power supplied
by the USB Type-C charger may be insufficient. As a result, the computer
may not operate at its full capacity and the battery charging may
stop or is very slow. Use the included ac power adapter whenever possible.
CAUTION:
When purchasing third-party USB Type-C chargers
for use with the computer, choose a product that is safety approved
or certified. A disqualified charger may cause damage to your computer
or pose an electrical hazard. In many countries and regions, manufacturers
or importers of electric chargers can submit their products to a certification
authority or approved and recognized testing laboratories. Such a
product usually carries a mark if it was tested to pass relevant quality
and safety standards. For some countries and regions, this certification
process is even mandatory. If you live in mainland China, choose a
charger with the “CCC” mark; for users in many European countries,
choose one with the “CE” mark; for users in the United States and
Canada, choose a Listed charger that carries a mark by one of the
Nationally Recognized Testing Laboratories. (For example, the “UL
Listed”mark). For people living in other countries and regions, consult
a qualified electrical engineer for how to select a safety approved
electric charger.
