Adaptador de alimentación
Este equipo portátil se envía con un adaptador de alimentación.
AVISO: Cuando desconecte el cable del adaptador de CA del portátil, sujete el conector del cable, no el propio
cable, y tire firmemente, pero con cuidado de no dañar el cable.
AVISO: El adaptador de alimentación funciona con tomas de alimentación eléctrica de todo el mundo. No
obstante, los conectores de alimentación y los enchufes múltiples varían de un país a otro. El uso de un cable
incompatible o la conexión incorrecta de un cable al enchufe múltiple o al tomacorriente pueden dañar el equipo
o provocar un incendio.

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
● New connectors and cable
The topics below cover some of the most commonly asked questions regarding USB 3.0/USB 3.1 Gen 1.
