Expanding the OmniBook

Installing a RAM Expansion Module

Installing a RAM Expansion Module

		The OmniBook has no memory (RAM) built in but has two slots for installing RAM
		modules. One slot contains a RAM module installed at the factory. You can use both
		slots to expand your RAM.

		To install a RAM expansion module
		You’ll need a small Phillips screwdriver for these steps.

CAUTION		Your OmniBook’s computer chips are extremely static-sensitive. Static electricity
		can permanently damage computer chips. Handle the RAM module only by its
		edges. Before installing the memory module, discharge your body’s static
		electricity by touching the metal shielding around the connectors on the rear of the
		OmniBook.
		For a model with “4150 B” after the serial number, you must use only PC-100 type
		RAM modules—other RAM modules will not function.
		1. From the Start menu, shut down the OmniBook.
		1. From the Start menu, shut down the OmniBook.
		2. Important. Unplug the ac adapter, if present, and remove the battery. (Remove a
		second battery if one is installed.)
		3. Turn the unit bottom side up, then remove the two screws from the RAM cover and
		remove the cover.
