Adding and removing a PC Card
Your convertible tablet PC has a PC Card slot (also known as a PCMCIA card 
slot). This slot accepts one Type II card.
You do not need to restart your convertible tablet PC when changing most cards 
because your convertible tablet PC supports hot-swapping. Hot-swapping means 
that you can insert a PC Card while your convertible tablet PC is running. If 
your PC Card does not work after hot-swapping, see the PC Card manufacturer’s 
documentation for further information.
To insert a PC Card:
■Push the card firmly into the PC Card slot label-side up until the outer edge 
of the card is flush with the side of your convertible tablet PC.

Preventing static electricity 
discharge
The components inside your convertible tablet PC are extremely sensitive to 
static electricity, also known as electrostatic discharge (ESD).
Before installing memory or replacing the hard drive, follow these guidelines:
■Turn off your convertible tablet PC.
■Wear a grounding wrist strap (available at most electronics stores) and 
attach it to a bare metal part of your workbench or other grounded 
connection.
■Touch a bare metal surface on your workbench or other grounded object.
■Unplug the power cord and the modem and network cables.
■Remove the battery. For more information, see “Changing batteries” on 
page 159.
■Disconnect all peripheral devices and remove any PC Cards.
WarningESD can permanently damage electrostatic 
discharge-sensitive components in your convertible 
tablet PC. Prevent ESD damage by following ESD 
guidelines every time you install memory or replace the 
hard drive.
WarningTo avoid exposure to dangerous electrical voltages and 
moving parts, turn off your convertible tablet PC and 
unplug the power cord and modem and network cables 
before opening the case.
WarningTo prevent risk of electric shock, do not insert any object 
into the vent holes of your convertible tablet PC.

Before working with computer components, follow these guidelines:
■Avoid static-causing surfaces such as carpeted floors, plastic, and packing 
foam.
■Remove components from their antistatic bags only when you are ready 
to use them. Do not lay components on the outside of antistatic bags 
because only the inside of the bags provide electrostatic protection.
■Always hold components by their edges. Avoid touching the edge 
connectors. Never slide components over any surface.
Adding or replacing memory
Your convertible tablet PC uses memory modules called SO-DIMMs (Small 
Outline Dual Inline Memory Modules). The modules are available in various 
capacities and any module can be placed in the memory bay. Use only memory 
modules designed for the Gateway M275 for upgrading your memory.
SO-DIMMs are located in two places inside your convertible tablet PC. Both 
SO-DIMMs can be upgraded. For instructions on upgrading the SO-DIMM 
located on the bottom of your convertible tablet PC, see “Adding or replacing 
memory in the memory bay” on page 256. For instructions on upgrading the 
SO-DIMM located under the keyboard of your convertible tablet PC, see 
“Replacing memory under the keyboard” on page 259.
