Useful Information

Operating Systems

The computer is compatible with most operating systems (OS). However, not all functions are 100% compatible.

For example, ACPI, APM, Smart Battery, etc. are not available on DOS, Windows NT, and other non-Microsoft OS. Consequently “Suspend”, “Hibernation”, “Battery Gauge” etc. would not work under such operating systems.

ACPI: Advanced Configurations and Power Interface

APM: Advanced Power Management

AC adapter

The AC adapter performs two functions:

•It powers the computer from an external AC source.

•It charges the computer battery.

The adapter automatically detects the AC line voltage (110V or 220V) and adjusts accordingly.

The following are recommended when using the AC adapter:

•Use a properly grounded AC outlet.

•Use one AC outlet exclusively for the computer. Having other appliances on the same line may cause interference.

•Use a power strip with built-in surge protection.

Connect the AC adapter:

1.Plug the AC cord to the adapter.

2.Plug the other end of the AC cord into the wall outlet. Make sure the green LED on the adapter turns on.

3.Attach the DC plug into the power jack of the computer; turn the lock ring clockwise to secure it.

AC Adapter Indicator

The green LED indicates that the AC power is ready.
