3 Technology and components This chapter details the technology and components available in the system. Topics: • Power adapter • USB features • Memory features Power adapter This laptop is shipped with power adapter. WARNING: When you disconnect the power adapter cable from the laptop, grasp the connector, not the cable itself, and then pull firmly but gently to avoid damaging the cable. WARNING: The power adapter works with electrical outlets worldwide. However, power connectors and power strips vary among countries. Using an incompatible cable or improperly connecting the cable to the power strip or electrical outlet may cause fire or equipment damage. USB features The Universal Serial Bus, or well known as USB was introduced to the PC world in 1996 which dramatically simplified the connection between host computer and peripheral devices such as mice and keyboards, external hard drive or optical devices, Bluetooth and many more peripheral devices in the market. Let's take a quick look on the USB evolution referencing to the table below. Table 2.

Power adapter
This laptop is shipped with power adapter.
WARNING:
When you disconnect the power adapter cable from the laptop, grasp the connector, not the cable itself, and then
pull
firmly
but gently to avoid damaging the cable.
WARNING:
The power adapter works with electrical outlets worldwide. However, power connectors and power strips vary
among countries. Using an incompatible cable or improperly connecting the cable to the power strip or electrical outlet may
cause
fire
or equipment damage.
USB features
The Universal Serial Bus, or well known as USB was introduced to the PC world in 1996 which dramatically
simplified
the connection
between host computer and peripheral devices such as mice and keyboards, external hard drive or optical devices, Bluetooth and many
more peripheral devices in the market.
Let's take a quick look on the USB evolution referencing to the table below.
