[senit] RE: Switching on a Computer

Using Sleep and Hibernate is not an 'perfect science'

Sleep mode (Windows 98, ME & 2000) powers down the monitor,  stops the disk drive(s) completely after copying the current state of your PC to system RAM.  If you get a power cut during Standby mode, say goodbye to any unsaved work because your RAM will lose its charge ( unless you have an uninterrupted power supply UPS which consists of electrical batteries with enough stored energy to keep the PC going for a limited period of time ).
Hibernation,  if your system supports it,  copies your present working condition of your PC to the hard disk before going into a deep power saving sleep ( hence hibernation ) and everything is switched off under software control..

Both Sleep & Hibernate options can / do have their problems,  like failing to wake up properly,  or not at all,  after sleep is induced.  Non-compliant peripherals or their drivers are often blamed.

If your PC wakes up from Sleep mode correctly more than 95 times out of 100 then count yourself lucky !

As for the main wall switch try http://www.ribaproductselector.com/DirectoryBrowseSymbolBuilding.aspx?ac=&sid=002%20210%20305%20070 who supply large size rocker switches.
