Before You Dock for the First Time

completed the setup process:
1
Ensure that the laptop is not connected to the E-Port (docked).
2 Turn on the laptop.
3 Verify that your laptop operating system has completed the setup process.
4 Verify that your battery is installed before docking your laptop.

10 Using the Dell™ E-Port
Docking Your Laptop
The E-Port can run on its AC power adapter, the laptop’s AC power or the
laptop’s battery. You can use the AC adapter to power the E-Port and the
laptop, which charges the battery.‘
NOTICE: Always use the Dell AC adapter that came with the E-Port. If you use any
other commercially available AC adapter, you may damage the E-Port or the laptop.
1 Complete the steps in "Before You Dock for the First Time" on page 9.
2 Place the E-Port so that there is enough flat space in front of it to
completely support the laptop when docked to the E-Port.
