Slimer is a simple sleep timer that I wrote for Windows XP. I wanted a really simple application that would put my computer in standby or hibernate mode after a user-defined amount of time (no matter what applications were running). Slimer is really simple and here is how it works:

1. A user is asked how many minutes they would like to wait before sleeping.

2. After the user enters the amount of time, Slimer disappears and runs in the background.

3. When time expires, Slimer puts Windows XP into standby mode or hibernate mode (if hibernate is enabled).

Note: Since Slimer runs in the background, if you would like to disable the sleep timer before time expires you can end the process through Windows Task Manager (CTRL + ALT + DEL).
