Installing device drivers, „ Checking battery status | Lenovo Y450

Chapter 2. Using your computer

Installing device drivers -----------------------------------------------------------

A compatible device driver is a requirement to ensure correct operation and performance of each component in your computer. If your computer is pre-installed with an operating system, Lenovo provides all drivers that you need in your hard disk.

Using battery and AC adapter -----------------------------------------------

When you cannot use the AC adapter to power your computer, you may depend on battery power to keep your computer running.

Note:

The operating system may run slower when using the battery mode.

Checking battery status

You can determine the percentage of battery power remaining by using Windows Power options.

As each computer user has different habits and needs, it is difficult to predict how long a battery charge will last. There are two main factors:

The amount of energy stored in the battery when you begin to work.

The way you use your computer: for example, how often you access the hard disk drive and how bright you make the computer display.
