Can't turn on Laptop, device is charging, trackpad haptic ok

Hi there.

Here's some tips to get you started:

Plug in an External Monitor: Reset the NVRAM once more. If you have FileVault enabled, enter the password after pressing the power button. Nothing will appear on the screen at first. If the external display comes on after hitting Enter, then the flex cable of your computer is broken. 2020年初13寸MacBook Air 显示屏更换

When you feel the haptic in the trackpad, press the Caps Lock key. If the little green light comes on, the Mac can detect the keyboard. If the light does not come on at first, wait a good three to five minutes to ensure the Mac does boot.

If nothing else, reseat the battery. 2020 年初13寸 MacBook Air 更换电池 Do not replace the battery, just unplug it, press the power button for thirty seconds, and plug the battery back in.

If none of these options work, we can go from there. Hopefully this can help you get started.
