Lenovo Thinkpad Yoga 14 Won't Turn on

It doesn't show signs of charging (no light) randomly stopped working. Happened once before. Randomly started working. Any way to fix w/o taking out battery?

Hi,

Here are some troubleshooting steps that I suggested to others that may help.
- First is to do a hard reboot, unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If it will still load into a blank black screen connect an external monitor and see if you'll get any display from it. If there's a display on the external monitor that could mean that the problem lies in the built in display. If you can, open the laptop and check the ribbon cable that connects the LCD to the motherboard.
- If there's still no display on the external monitor you'll need to reseat the RAMs', turn the laptop completely off and unplug it from its AC adapter then remove all the RAM's off then put them back in making sure everything is seated properly.
- If reseating the RAM's will not work then the problem is the motherboard, do contact the manufacturer of the laptop if it's still under the factory warranty for a repair.
