1 Fan louvers
The fan louvers and the internal fan enable air to circulate in the computer to ensure proper cooling,
especially the cooling of the microprocessor.
Note: To ensure proper airflow, do not place any obstacles in front of the fan louvers.
2 Always On USB 3.0 connector
By default, the Always On USB 3.0 connector enables you to charge the USB-compatible devices in the
following situations:
• When your computer is on or in sleep mode
• When your computer is in hibernation mode or is turned off, but connected to ac power
Attention: When you attach a USB cable to this connector, ensure that the USB mark is facing upward.
Otherwise the connector might get damaged.
If you want to charge these devices when the computer is in hibernation mode or is turned off, and the
computer is not connected to ac power, do the following:
®

follow the instructions on the screen.
