| 1. Ventilation slots (outlet) | Maintain the outgoing airflow to dissipate internal heat. Attention: Do not block the ventilation slots. Otherwise, the
computer may overheat.
|
| 2. USB (3.2 Gen 1) Type-A connector (always-on) | The always-on connector can charge external devices when the
computer is turned off, in sleep or hibernation mode. The always-on
function can be turned on or off in the UEFI/BIOS setup utility. Note: If Lenovo Vantage is pre-installed on your computer, you can also
set always-on function from within that software.
|
| 3. Combo audio jack | Connect to headphones or headsets with a 3.5 mm (0.14 inch),
4-pole plug. Note: This jack does not support standalone external microphones.
If you use headsets, choose one with a single plug.
