On/off power switch problematic

Problem switching on power in Dell PC Studio
I have to press the on/off button numerous times before it works.
It does not seem to be a problem of the power supply as the small green light new the power socket (at rear of PC) lights up as soon as I connect to the Wall socket.

If this is a standard tower, you can follow the wires from the switch to the motherboard.  You can test the motherboard by pulling the power switch cable from it and shorting the two pins on the motherboard together (a screwdriver works well for this).  If that works reliably, the issue is likely in the switch itself.

Of course, don't do any of what I mentioned above if you don't feel you have the skills to do it safely.

I've done a workaround for bad power switches numerous times.  In the BIOS there is very likely a setting for what to do when power goes out and then comes back on.  I'll set that to automatically start the computer (the other choices are typically to leave it off or to return to previous state).  That way, if you pull the power cord (you have to wait a minute or two until the light goes out) and then plug it back in, the system will start up.  It's not ideal but it will let you get your computer back up.

If this is the tiny Dell Studio Hybrid Desktop that's about the same size as a large external DVD drive there's nothing standard about it, look up the serial number at Dell support and see what is listed in the BOM. If you can post the SN we can look it up for you.

Yes, it worked when I changed the power supply.
