my lenovo thinkpad laptop was fine until last night when it said it had a problem and needed to restart itself, i have restarted it several times but i have an non removable battery so i can not reset it any other way. It turned black and now it is just showing white and pink vertical lines. i am not able to do anything on the computer and i have tried plugging it into a external monitor but i can not access anything on the computer so i can not get the IP address so i can not get the external monitor to work. PLEASE HELP ASAP!!
