Touch switch shutdown/start problems
Both my computer and a printer have problems with the start/stop touch
switch. The computer intermittantly shutsdown and is difficult to restart. The printer spontaneously restarts after shutdown. After shutdown neither will start again immediately after the touch switch is pressed. I assume a capacitance effect is causing the problem but don't really know. Can anyone enlighten me with a typical circuit for touch on/off switches and advise whether my problems are likely to be repairable (short of major surgery or board replacement). With regard to the computer (ATX power supply) is the problem more likely to be with the motherboard or power supply. Can one can swap an AT supply for the ATX as a work around or test? Many thanks in anticupation of your guidance . |
