Did you try holding the power button for 10+ seconds ''with the battery or power connected'', to force shutdown the laptop out of sleep mode and then try to start it again?
Do you know what the charge status of the battery was just before the laptop lid was closed, before it refused to start again?
To me no LED indications at all when the charger is connected indicates a power problem.
It may be that the USB-C port is loose from the motherboard and therefore no power is extended from the charger through to the motherboard.
This could also cause the battery to eventually lose charge if it was only intermittently being charged, if at all and therefore nothing happens when the charger is connected or the power button is operated.
I would check first that there is power getting to the motherboard when the charger is connected.

If there is, check if there is power at the battery terminals and if so what voltage is being shown there.

After that you would need to check if the power regulators on the motherboard were OK but you would need the schematics for that.

Do not open the laptop if the laptop is still under warranty as you will void the warranty. Get it fixed under warranty.

If no longer covered by the warranty, here's a [https://www.youtube.com/watch?v=tj0ZYmclGsg|video] that shows how to open the laptop so that the charge port can be inspected etc.
