For Seniors: Install and Charge a Laptop Battery
Once you unpack your new laptop, you might need help getting it set up, such as installing and charging its battery. After installing a laptop's battery, you'll need to charge it fully before using it. Then you'll need to recharge the laptop's battery every once in a while in order to keep it fully charged and ready.
Insert the laptop battery.
The battery is a rectangular affair that slips into the bottom of your laptop.
Tablet models are typically sealed so that your battery is not accessible; if yours is one of those, you don’t have to insert a battery; just plug the tablet in to charge the battery.
Plug one end of the laptop cable into a wall outlet.
The laptop plug is usually a two-piece cable; one half of the cable has a large, boxy transformer on one end that plugs in to the other half. After putting these two pieces together, plug one end into the wall outlet.
Plug the other end into the round power connection port on your laptop.
The laptop's user’s manual should indicate where to plug in the power cord (usually on the back or near the back of the right or left side of the laptop.
When the laptop is on, a battery icon appears on the right side of the Windows taskbar, located at the very bottom of the screen. Click this icon to see whether the battery is fully charged to 100-percent capacity. This icon changes to just a battery (no plug) when the computer isn’t plugged in; this battery icon indicates visually how much charge your battery has left before it drains.
It's a good idea to charge your battery completely when you first plug it in, which could take several hours.
