My laptop has been unplugged overnight. When I woke it this morning it crashed. I did a hard power off and reboot plugged in. I managed to get the desktop through login using my fingerprint. However I cannot type nor use the touchscreen. It hangs on processing then it shuts down or the screen goes alternative from blue to white to black.
Hello I apologize for the issue your having with the touchscreen. I was able to find some information regarding this issue here: https://www.samsung.com/us/support/troubleshooting/TSG01205023/ to review. Regrettably, if this does not resolve your issue, the next recommendation would be to have a technician service the device. You can send the full model and serial number, name, address, e-mail, contact number and place of purchase here: https://bit.ly/3lVQyQ2 to explore that option.
