That's why I need a laptop.. with beverage holder.
There is usually a little button next to or underneath a small rectangle on the computer. The rectangle is typically 1/2 inch tall and about 4 1/2 inches wide. If you will press the button, the cup holder will extend. Please note that this is NOT designed for the quart bottles but should be limited to standard 12 oz cans.
Glad to help,
