Ergonomic Computing Habits
CAUTION: Improper or prolonged keyboard use may result in injury.
CAUTION: Viewing the display or external monitor screen for extended periods of time may result in eye strain.
For comfort and efficiency, observe the ergonomic guidelines in the Tell Me How help file when setting up and using your computer (see "Accessing Help" on page 26).
When Removing or Installing Memory Modules
Before removing or installing memory modules, perform the following steps in the sequence indicated.
NOTICE: The only time you should ever access the inside of your computer is when you are installing memory modules.
NOTICE: Wait 5 seconds after turning off the computer before disconnecting a peripheral device or removing a memory module to help prevent possible damage to the system board.
1Turn off your computer and any attached peripherals.
2Disconnect your computer and peripherals from electrical outlets to reduce the potential for personal injury or shock. Also, disconnect any telephone or telecommunication lines from the computer.
3Remove the main battery from the battery compartment and, if necessary, the secondary battery from the module bay.
4Ground yourself by touching the unpainted metal surface of the I/O panel on the back of the computer.
While you work, periodically touch the I/O panel to dissipate any static electricity that might harm internal components.
Protecting Against Electrostatic Discharge
Static electricity can harm electronic components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computer’s electronic components, such as a memory module. You can do so by touching an unpainted metal surface on the computer’s I/O panel.
