Stopwatch on laptop keyboard. Deadline concept.

Windows, Mac OS X, and Linux all allow you to schedule boot-ups, shut-downs, and wake-ups. You can have your computer automatically power up in the morning and automatically shut down at night, if you’d like.

This is less necessary than ever thanks to sleep mode — a typical laptop just enters low-power sleep mode it can quickly resume from when it’s not being used — but may still be useful for desktop PCs.  Read more >>

Windows’ BitLocker encryption defaults to 128-bit AES encryption, but you can choose to use 256-bit AES encryption instead. Using a 256-bit AES key could potentially offer more security against future attempts to access your files.

Is this really more secure? Well, that’s a matter of some debate. You might naively assume that 256-bit encryption offers more security, but it isn’t that clear.  Read more >>
