Laptops often use smaller memory modules
to save space.
Types of Memory used in Laptops

Small Outline Dual Inline Memory Module
(SODIMM)

Dual Data Rate Synchronous RAM (DDR
SDRAM)

Single data rate Synchronous RAM (SDRAM)

Proprietary memory modules
Hard Drives used in Laptops

Hot swappable


Warm swappable


The computer can stay on while changing the
drive.
The computer can stay on while changing the
drive, but the corresponding bus (the path the
drive uses to send data to the CPU) must be
inactive.
Cold swappable

The computer must be off during the swap.
Laptop Screen and Graphics

A laptop uses a Graphics Processing Unit
(GPU) to generate graphics.

A laptop displays its graphics on a liquid
crystal display (LCD) screen.

Most screens of the laptops
between 10 and 17 inches
measure
Types of Laptop Batteries

Nickel-Cadmium (NiCad)


Nickel-Metal Hydride (NiMH)


These batteries were the first type of battery
commonly used in laptop computers.
These batteries are the bridge between NiCad
and the newer Lithium-Ion (LiIon) batteries.
LiIon batteries

These are the current standard for laptop
computers.
