If still not turning on try a full power refresh and check if this resolves the problem. If not it’s a hardware problem on the motherboard.
Here’s how:
Disconnect the charger if connected.
Turn off the laptop (hold power button operated for >4 seconds then release).
Open the laptop and disconnect the main battery from the systemboard.
Remove the RTC coin cell battery from the motherboard. Remember the orientation of the battery (+ve on top - when the battery is out measure its voltage. If it is <2.5V DC replace it. The battery type is printed on the battery e.g. CR2032.

Press and hold the Power button for a ''full 30 seconds'' and then release it.
Reinsert the RTC coin cell battery (remember the orientation), reconnect the main battery, reassemble the laptop, connect the charger and try turning it on.
If it turns on, check if the battery is charging.

Once charged etc, create a [https://www.windowscentral.com/generate-battery-report-windows-10|battery report] to check the status of the battery. Compare the ''Design Capacity value'' versus the ''Full Charge Capacity value.'' For a good battery they should be very close to being the same value.
