How to Connect an Acer Monitor to a MacBook

Look at the ports on the left side of the MacBook and the back of the Acer monitor. A MacBook can be connected to an external monitor that has either a DVI or VGA port. The ports on the monitor will either be labeled or have a corresponding icon next to them. If you are unsure what an icon means, look in the 'Features' section of your user manual. Make sure your Acer monitor model has the correct port.
Plug one end of the connection cable into the monitor and the other end into the MacBook. If you are using a DVI cable connection, plug each end directly into each device. If you are using a VGA cable connection, you have to use the mini-DVI-to-VGA adapter that comes with your MacBook. Plug one end of the VGA cable into the VGA end of the adapter and insert the adapter DVI end into the laptop. Plug the other end of the VGA cable into the monitor.
Turn on both devices. After your MacBook powers up, it will automatically detect and display the desktop on both screens. Your Acer monitor is now ready for configuration.
Click on the 'Apple' icon on the top left corner of the desktop. From the drop-down list, select 'System Preferences' followed by 'Display.' A new 'Display' window will appear that has the available options that can be changed. For example, you can change the screen resolution of the Acer monitor, change the arrangement of the displays and whether you want to mirror the MacBook's display, or extend the desktop to the Acer monitor.

How to Replace a MacBook Battery (5 Steps)

Turn your MacBook upside down, with the Apple logo facing downward. Check the bottom panel for a removable battery. If the bottom panel is a solid block, you have a 'uni-body' MacBook, and the battery can only be replaced by an Apple authorized service technician.
Purchase a replacement battery from an Apple Store, an Apple authorized reseller or a third-party manufacturer. Be certain to purchase a battery specific to your MacBook model. Batteries made for other MacBooks may not fit in the case or may supply the wrong amount of power.
Use a coin to turn the circular lock slot of the battery clockwise 90 degrees, or one-quarter turn. The battery will pop out slightly, allowing you to lift it by its case out of the battery well.
Insert the new battery in the same orientation that the original battery was placed, lining up its connector with the power jack in the MacBook.
Press the battery gently and turn the lock slot counterclockwise to lock the battery in position.
