The newest models in the Acer Aspire line of notebook computers include the ability to rotate the screen image on the laptop's display. By performing a simple keyboard shortcut, you can flip your screen upside down or rotate it 90 degrees. This feature may be useful if you do not need to use the laptop's keyboard and would rather hold the machine in an alternate way when reading a document or viewing media.
Start up your Acer Aspire laptop and log in to the Windows operating system.
