Hi,
Does it do this with the charger connected and switched on, you didn’t say?
Try a power refresh and check if it starts OK.
Disconnect the charger if connected.
Remove the battery from the laptop.
Press and hold the laptop Power button for a full 30 seconds and then release it.
Reinsert the battery.
Reconnect and switch on the charger and turn on the laptop and check if it starts OK
