I need to use my laptop computer as an alarm clock. The laptop is specifically an X301 running Vista Enterprise

Features I am looking for in this application, ordered by importance:

  1. Will work even if laptop is in sleep mode
  2. Is audible even if the OS volume is muted/low (automatically adjusts OS volume)
  3. Customizable alarm sound
  4. Snooze (with customizable interval)
  5. Gradually increases alarm sound

Sidenote: I usually use the alarm clock on my cell phone, but it was stolen yesterday :(

Note that unmuting probably won't work if you muted sound with the volume control buttons on your keyboard. At least on my R60 they're done in hardware and have no relation whatsoever to the volume setting in Windows. – Joey Aug 11 '09 at 23:49

Citrus Alarm Clock used to be free, if you want an old version – zildjohn01 Aug 11 '09 at 23:48
20 MB download is amazingly large for a simple alarm clock app, but Alarm Clock of Justice gets the job done. (Also wish there was a default sound if no media file is selected, yet.) – Leftium Aug 25 '09 at 16:02

I found this app that says it will wake up a computer from sleep mode.

There was an alarm clock power toy for XP Media Center Edition (it won't work on Home or Pro).

...only useful if we know what version of Windows your running.
