Upgradeable memory and hard disk

Display

The large graphics display offers excellent viewing, excellent display quality and high performance desktop graphics. The computer supports two different display configurations — High Performance Addressing (HPA) or Thin-FilmTransistor (TFT).

Video Performance

The PCI local bus video with 128-bitgraphics acceleration and 2MB Extended Data Out (EDO) video RAM boosts video performance.

Simultaneous Display

The computer’s large display and multimedia capabilities are great for giving presentations. If you prefer, you can also connect an external monitor when giving presentations. This computer supports simultaneous LCD and CRT display. Simultaneous display allows you to control the presentation from your computer and at the same time face your audience. You can also connect other output display devices such as LCD projection panels for largeaudience presentations.

Power Management

The power management system incorporates an “automatic LCD dim” feature that automatically decides the best settings for your display and at the same time conserves power. See “Power Management Modes” on page 30 for more information on power management features.

Opening and Closing the Display

To open the display, slide the display cover latch to the left and lift up the cover. Then tilt it to a comfortable viewing position. The computer employs a microcircuit that turns off the display (and enters standby mode) to conserve power when you close the display cover, and turns it back on when you open the display cover.

Note: If an external monitor is connected, the computer turns off the display (but does not enter standby mode) when you close the display cover.

To close the display cover, fold it down gently until the display cover latch clicks into place.
