This may be a newbie question, but i'd like some schematics for the ON/OFF switch of your standard computer. In other words, a solid-state switch that will allow the computer to do a soft OFF procedure, where the computer boots down before turning off.
Ideally, it would be 3-4 seconds push-to-hold to start the power-ON and boot-up sequence. And3-4 seconds push-to-hold to bring up a "Do you really want to shutdown? YES/NO" prompt on the LCD screen, and after touching "YES" on the screen, the computer will boot down the OS, and shut down.
However, if the boot down somehow hangs up, i'd like to retain the option of a "hard-turn-OFF", like almost all computers now have, where the ON/OFF button can be depressed for something like 5 seconds, and the computer will shut down immediately (no "soft" OFF boot down).
If anyone out there has a schematic, that would be great. Thanks.
