You should see the battery charging symbol in the tray of your laptop screen. On Windows, this looks like the battery icon next to a three-prong plug as the icon is filling up with white. On a Mac, you’ll see a lightning bolt inside the battery icon.

If you’re using Windows 8 or 10, make sure you look in your taskbar for programs that are running in the background, like Google Drive (or any of those other syncing services) or a gaming launcher (like Origin Games).

For example, if you need to write a document, use Notepad/TextEdit instead of Microsoft Word. Watching a movie or playing a large game can also drain your battery quickly. You can open up task manager (Windows) or activity monitor (Mac) to see what programs you’re using are taking up the most resources.

You should see a shortcut key on your keyboard that will do this. It will have a picture of a hollow sun next to a picture of a filled sun, indicating it adjusts brightness.

Likewise, you do not want to use a pillow or other soft surface to rest your computer.
