HP Recommended
Product: HP Pavilion All-in-One - 23-q055na (Touch)
 

AIO was switched off and disconnected. After re-connection, machine is totally unresponsive. No LED, either at power switch or above input socket.

Suspect issue with PSU.   Voltage measured is 15.3V instead of stated 19.5V.

 

Is this acceptable? Should the machine still work at this voltage or is 19.5V essential?

Is the problem elsewhere?
