Replacing Gateway M275 Components

Preparing your work space
Before performing maintenance on the convertible tablet PC, make sure that your work
space and the convertible tablet PC are correctly prepared.

4

■

Wear a grounding (ESD) wrist strap, and use a grounded or dissipative work mat.

■

Use a stable and strong table, and make sure that the table top is large enough to
hold each component as you remove it.

■

Use bright lighting to make part identification easier.

■

Keep your work surface free from clutter and dust that may damage components.

■

Use a magnetized screwdriver for removing screws.

■

When removing components that are attached to the convertible tablet PC by a cable,
unplug the cable before removing the screws, when possible, to avoid damaging the
cable.

■

As you remove components and screws, lay them toward the rear of your work surface
(behind the convertible tablet PC) or far enough to the side that your arms do not
accidentally brush them onto the floor.

■

To help keep track of screws, try the following:
■

Place each component’s screws in their own section of a parts sorter.

■

Place each component’s screws next to the component on your work surface.

■

Print the first page of each task, then place the page toward the rear of your work
surface. As you remove screws, place the screws in their respective boxes on the
page. Where screw measurements are shown, the first number indicates screw head
width, and the second number indicates screw length.

■

After loosening screws that are deeply recessed in a hole (for example, on the
bottom of the base assembly), you can leave the screws in the holes if you place
small pieces of masking tape over the hole openings. When reassembling the
component, just remove the tape and tighten the screws.

■

When you place flat-headed screws on your work surface, stand them on their
heads to prevent the screws from rolling off the table.

Preventing static electricity discharge

Preventing static electricity discharge
Important

Before performing maintenance on the convertible tablet PC, you
should read and understand the information in this section.

The components inside your convertible tablet PC are extremely sensitive to static
electricity, also known as electrostatic discharge (ESD).
Warning

To avoid exposure to dangerous electrical voltages and moving parts,
turn off your convertible tablet PC and unplug the power cord, modem
cable, and network cable before opening the case.

Warning

To prevent risk of electric shock, do not insert any object into the vent
holes of the convertible tablet PC.

Before performing maintenance on the convertible tablet PC, 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.

■

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.

Adding or replacing memory modules

Adding or replacing memory modules
The 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 the memory.
SO-DIMMs are located in two places inside the convertible tablet PC. Both SO-DIMMs can
be upgraded. For instructions on upgrading the SO-DIMM located on the bottom of the
convertible tablet PC, see “Adding or replacing memory in the memory bay” on page 25.
For instructions on upgrading the SO-DIMM located under the keyboard of the convertible

Caution

By law, only approved wireless modules provided by Gateway, or a
Gateway authorized representative, explicitly for the Gateway M275
may be installed in this convertible tablet PC.

Caution

Legal requirements dictate that a security screw (or other means) be
used to attach the mini-PCI cover plate to the system board in a
manner that restricts end user access. End users are strictly
prohibited from having access to the wireless card. Gateway M275
convertible tablet PCs require a Torx head security screw to attach
the mini-PCI cover plate.

Legal requirements dictate the mini-PCI cover plate be in place during
any and all operation of the convertible tablet PC’s wireless feature.
