Hi. My name is***** you for your question and the opportunity to assist.
Please try this to see if you can get the laptop to turn back on.
Remove the charging cord from the laptop.
Firmly hold down the power button for 30 seconds and release.
Plug the charger back in to the laptop and press the Power button to start it up.
That's a starting point.
From you description of what happened it sounds like there's an internal short on the laptop
that occurred when the USB cable was removed.
Does anything at all happen when the power button is pressed.
When the laptop is plugged in to power are there any lights on
like by the charging port or the power button itself?

If it's totally dead it needs to be manually inspected.
If it's out-of-warranty you might consider using a local shop.
