Hi,
I understand that your PC is not turning on. Only the power led is glowing. It means that there is no issue with the power supply. I request you to perform power drain, please follow the steps given below:
1.Disconnect all the external devices from your PC. (power adapter etc)
2.Now turn over the laptop and remove the battery
3.Press and hold the power button 10-15 seconds to remove the static charge from the motherboard.
4. Once done, directly connect the power adapter and power on the PC.
