Q: I'm a student using a Apple MacBook and I'm often switching between working on the laptop, taking notes, and reading online. The problem is my machine will go into sleep mode while I'm reading or writing (in a notebook) for long periods of time, but I like keeping my machine's sleep settings at 30 minutes normally for power saving. Is there a quick way to prevent my laptop from going to sleep before it powers down?

Editor: Try installing Should I Sleep, a OS X system extension which uses the computer's built-in webcam and microphone to determine whether you're still there, preventing the machine from going into sleep mode. If the computer "sees" your face or hears noise, the system continues operating. If nobody is in front of the computer, the machine will go into sleep mode as normal.
