My son's laptop (Envy 4-1130us) will not boot and the LED next to the power adapter port does not come on. However, I can measure 19.5VDC at the point the power port connector attaches to the main board inside the laptop, so I'm sure the power adapter and the connector are in good shape.
Can anyone tell me if the likely cause is the mother board (main board)? I could see the power switch causing it not to start, but I don't think that would cause the LED to not work. Could a bad battery cause this problem? Also, I have disconnected the HD, SSD, and the USB port board, but that didn't change anything.
Thanks for your help,

Hey there! @nashville_bill,
Do you see any blinking lights on the caps lock or num lock key on the PC?
It certainly sounds like a hardware issue with the laptop. The system board on the laptop could have gone faulty.
However, please try the steps recommended below and check if it helps.
Check if the pin inside the DC (Charging) port is bent or broken.
Please try the steps recommended below.
To perform a power reset on a laptop with a removable battery, use the following steps:
Turn off the computer.
Remove the computer from any port replicator or docking station.
Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
Unplug the AC adapter from the computer.
Remove the battery from the battery compartment.
With the battery and power cord unplugged, press and hold the Power button for about 15 seconds to drain any residual electrical charge from the capacitors.
Insert the battery and plug the AC adapter back into the laptop, but do not connect any of the peripheral devices.
Press the Power button to turn on the computer.
If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key.
After Windows opens, reconnect each peripheral device that was disconnected, one device at a time, until all devices are reconnected.
Your laptop has been reset. After a power reset, it is a good idea to run Windows Update and HP Support Assistant to update all device drivers.
