Display
The large graphics display offers excellent viewing, excellent display quality
and high performance desktop graphics. The computer supports two
differ ent display configurations — High Performance Addressing (HPA) or
Thin-Film Transistor (TFT).
Video Perform ance
The PCI local bus video with 128-bit graphics acceleration and 2MB
Extended Data Out (EDO) vi deo RAM boosts video performance.
Simultaneous Display
The computer’s large display and multimedia capabilities are great for giving
presentati ons. 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 out put display devi ce s such as LCD projection panels for l argeaudience presentations.
Power Management
The power management system incorporates an “automatic LCD dim”
feature tha t automat ical ly deci des the be st settings f or your di splay and at the
same time conserves power. See “Power Management Modes” on page 30
for more informa tion on power management features.
Opening and Closing the Display
To open the displ ay, slide the display cover latch to the left and lif t up t he
cover . Then til t it to a comfortab le viewing posi t ion. The comput er employ s 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 o pen
the display cover.
Note:
If an external monitor is connected, the compu ter turns off the
display (but does not ent er standby mode) when you close the
display cover.
To close the display cover, fold it down gently unti l the display cover latch
clicks int o place.

Power Management
This computer has a bui lt-in power management unit that monitors system
activit y. System activity refers to any activity involving one or more of the
following devices: keyboard, mouse, floppy drive, hard disk, peripherals
connected to the ser ial and parallel port s, and video memory. If no activit y is
detected for a period of time (called an inact ivity time-out), the computer
stops some or all of these devices in order to conserve energy.
This computer manages its power according to the way you use your
computer. This means the computer delivers maximum power when you
need it, and saves power when you don’t need the maximum — all without
your interve nti on. There are no timers to set, because the power
management system figures out everything for you.
Power Management Modes
Display Standby Mode
Screen activity is determined by the keyboard the built-in touchpad, and an
external PS/2 pointing device. If these devices are idle for the per iod
determined by the computer’s power management syst em , the display shuts
off until you press a key or move the touchpad or ext ernal mouse.
“Automatic Dim” Feature
The computer has a unique “automatic di m” power-saving featur e. When the
computer is usin g AC power and you di sconnect the AC adapter from th e
computer, it automatically dims the LCD backlight to save power. If you
reconnect AC power to the com puter, it automatically adj usts the LCD
backlight t o a bri ghter level.
Hard Disk Standby Mode
The hard disk enter s standby mode when there are no disk read /write
operations within the period of time determined by the power management
system. In this state, the power supplied to the hard disk is reduced to a
minimum. The hard disk returns to normal once the computer accesses it.
System Standby Mode
The computer consum es very little power in Standby m ode. Data remain
intact in th e system memory until the battery is drained.
There is one necessar y condition for the comput er to enter Standby mode:
❑
Heuristic Power Management Mode must be set to [ENABLED].
There are four ways to enter Standby mode:
