White lite, won't charge

[Lisawilliams77532]

I have a hp windows 10 touch screen laptop. When I plug it in it won't charge and when in push the power button it flashes a white light by the charging port but won't turn on. I have taken the battery out and unplugged it and held down the power button 30 seconds and put it all back together and it still does the same thing. Help

Please do try these troubleshooting steps that may help.
- Start by doing a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try loading it again in BIOS.
- If these will not work proceed with reseating the RAM's, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- If these steps will still not work, connect an external monitor and see if you'll get a display on it. If there's a display on the external monitor that means the problem lies in the built in LCD or the ribbon cable that connects the display to the motherboard.
- Try to open the laptop and check the ribbon cable if it's connected properly. You can take both ends out then put it back in just to make sure it's seated properly.
- But if there's also no display on the external monitor the problem lies in the motherboard.
