  1. One gigabyte (GB) = one billion bytes; accessible capacity will be less and actual capacity depends on the operating environment and formatting.
  2. Some USB devices (e.g. mobile telephones) require a driver in order to utilize the USB charging function. In this case, the USB charging function will not work when the notebook is switched off, as no drivers are active when the notebook is switched off.
  3. Battery life tested using Bapco® MobileMark 2014 Office Productivity Workload and Windows® 10 operating system, and may include audio muted and power saving utility enabled. Battery life will vary depending on the product configuration, product model, applications loaded on the product, power management settings on the product, Operating System, and the product features used by the customer. As with all batteries, the maximum capacity of the installed batteries will decrease with time, usage, and how often the batteries are charged by the user.
  4. Service and warranty turnaround time may vary by country and product. The International warranty is only valid for products purchased in North, Central, and South America.
