I have purchased the new Lenovo T61 thinkpad for my personal and professional use. I donít have any problem with the working of the system till last week. But after that I have faced serious problem with it. My model is 6459CTO with a 15.4 WSXGA screen. At last week my notebook screen had dead. I get completely dark screen. I cannot understand the problem. So I tried to search the answer on the web then I come to know that the problem is related to backlight but I cannot get the proper solution for that. Can anyone give me some suggestion to solve this problem? Please help me.
