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.

USB 3.0/USB 3.1 Gen 1 (SuperSpeed USB)
For years, the USB 2.0 has been firmly entrenched as the de facto interface standard in the PC world with about 6 billion devices sold, and
yet the need for more speed grows by ever faster computing hardware and ever greater bandwidth demands. The USB 3.0/USB 3.1 Gen 1
finally has the answer to the consumers' demands with a theoretically 10 times faster than its predecessor. In a nutshell, USB 3.1 Gen 1
features are as follows:
•
Higher transfer rates (up to 5 Gbps)
•
Increased maximum bus power and increased device current draw to better accommodate power-hungry devices
•
New power management features
•
Full-duplex data transfers and support for new transfer types
•
Backward USB 2.0 compatibility
