The laptop can be run either by battery power or it can be plugged into a wall outlet with the AC Adapter. It is recommended that when you are connected to the network, you run the laptop using AC (electrical) power.

The power button for the laptop is round and is located on the right side of the unit. Depress this button and hold down for a couple seconds to turn the laptop on. The laptop should be powered down by clicking on Start, Shutdown.
The battery when fully charged should last approximately 3 hours, however extensive use of network applications (particularly wireless) drains the battery faster.
When you are using battery power, there is a small ‘battery’ icon on the task-bar in the lower right-hand side of the Windows desktop. Holding the cursor over this icon will result in a small label displaying the percentage of power or the amount of time left on the battery. A single click on this icon presents a pop-up menu that allows you to toggle between a status display of percentage or number of hours remaining.
The laptop will notify you via a pop-up dialog box when the battery begins to run low. At that point, you should save any work to a floppy disk or transfer it to your email account and shut down the laptop. (Remember if the laptop is shutdown all files saved to the hard disk will be deleted.) If you wish to continue working after a low battery warning, without shutting down, you should power the laptop with the AC adapter and a wall outlet. When the laptop is plugged in, the battery will begin recharging.
