Dead PC

PC won't turn on.  The power adaptor output is 11.9 v.  Suspect power supply died.

@caleb1517 -- do you have a friend with a "multimeter" device? It can measure both the Voltage and Amperage being produced by the power supply, to see if your guess is correct.

Can you take your computer to a local computer store, to see if they have a compatible power-supply that can replace yours?  Test it in the store. If the replacement does not solve your issue, you probably have some other problem "inside" your All-In-One.

I measured the output voltage myself and it was a nominal 19.5 volts.  Took the PC to an Electronics/Computer center and they confirmed the problem is with the motherboard.  Considering the machine was purchased in late 2014, I accept it's simply at end of life.  Thanx for the suggestions.

Did you also measure the Amperage?  Remember that Wattage is Amperage multiplied by Voltage.

To compare, in a battery, each chemical reaction produces 1.5 V. But, for the battery to be useful, you need literally thousands of simultaneous reactions.

Too bad about the "death" of your motherboard.  So, Windows 11 may be in your immediate future.
