The Dell™ E-Port supports the Dell E-Family laptop computers, but it is not compatible with any previous series laptop computers.
The E-Port enables you to connect your laptop computer to the following external devices:
|RJ-45 NETWORK CONNECTOR — Connects a network interface cable.|
|DOCKING CONNECTOR — Connects a laptop to the E-Port.|
|AUDIO CONNECTORS — Connects audio headphones or speakers and a microphone.|
|USB 2.0 CONNECTORS — Connect up to five USB 2.0 compliant devices, such as a USB mouse. Three USB connectors are on the left side, and two USB connectors are on the back of the E-Port.|
|AC ADAPTER CONNECTOR — Connects the AC adapter.|
|DISPLAYPORT CONNECTOR — Connects external monitors equipped with a DisplayPort interface (also HDMI and DVI monitors via dongle; available at Dell.com).|
|DIGITAL VIDEO INTERFACE (DVI) CONNECTOR — Connects an external monitor equipped with a digital video interface.|
|VGA VIDEO CONNECTOR — Connects an external monitor.|
|USB OR ESATA CONNECTOR — Connects and supports USB or Dell-powered E-Family or standard selfpowered eSATA devices.|
|E-MONITOR STAND CONNECTOR — Connects to the monitor stand; available at Dell.com.|
Before you begin any of the procedures in this section, follow the safety instructions that shipped with your computer.
NOTE: If the cable connector of the external device has thumbscrews, tighten the screws to ensure a proper connection.
If you attach an external monitor to the E-Port, you may need to press <Fn> <F8> one or more times to switch the screen image to the desired location. If the laptop cover is closed, you can press <Scroll Lck> <F8> on an attached external keyboard to switch the image.
Before you initially connect your laptop to the E-Port, the operating system must complete its setup process. To verify that the operating system has completed the setup process:
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.
Antitheft devices usually include a segment of metal-stranded cable with an attached locking device and associated key (available at Dell.com). For instructions on installing this kind of antitheft device, see the documentation that came with the device.
The E-Port has the following security features:
LOCK/UNLOCK SWITCH — Move the lock toward the front of the E-Port (locked) to secure the laptop to the E-Port. Move the lock toward the back of the E-Port (unlocked) before pressing the eject button to undock the laptop. The red color in the security cable slot indicates the E-Port is unlocked.
SECURITY CABLE SLOT — Attach an antitheft device to the E-Port to secure a laptop to the E-Port.
The E-Port power button is used to turn a docked laptop on or off. The power button light indicates the power status of the E-Port or a docked laptop. The docking light on the eject button indicates the AC power and docking status of the E-Port and the laptop.
The following table shows all of the possible conditions of docking, power, laptop states and how these conditions are indicated by the E-Port power button and docking lights:
|Power and Docking Status||Laptop Status||Power Button Light||Docking Light|
|Unit undocked or no AC adapter connected||Hibernate or Off||Off||Off|
|Unit docked and AC adapter connected||Hibernate or Off||Off||On|
|Unit docked using AC or battery power||Standby||Breathing||On|
|Unit docked using AC or battery power||On||On||On|
The E-Port supports three video ouptut formats—VGA, DVI, and DisplayPort. You can use your E-Port for dual monitor display. Refer to the table below for using the E-Port with dual monitors.
|Monitor 1 connection||Monitor 2 connection|
NOTICE: Do not pick up the laptop or the E-Port when the laptop is docked. Doing so can damage the connectors on the laptop and on the E-Port.
