I need your help here. I bought a refurbished T410 in Oct. 2015 from Newegg. It has a Win7 professional. Today, when I turned on the computer, it first give out a brief "Thinkpad (?)", then it gave out a brief green screen. Finally it will stay on a 'black' screen. It seems that my screen is 'good' since it first has very briefly "Thinkpad (?)". Recnetly I have downloaded software, which I supspect it has virus on it. Also to day, before I turned the computer off, I changed the computer time to 01Jun2015. I am not sure if these activities are related to my 'black' screen?
I later connected a external display and I could do everything on it, my external display is good.
1. Lenovo 'black' screen.
2. external display is working.
3. when the computer is turned on, 'Thinkpad' briefly showed up, then a brief green screen, then goes to 'black'
Please give me your advices. Thanks.

Does it still show the ThinkPad logo when you boot? If yes try pressing the F1 key briefly and see if you can get into the BIOS.
What is the 7 digit TYPE number of your ThinkPad? You can find it in a black and white sticker on the bottom of the laptop, don't post the S/N number here.

Hi. Thanks for the help. I did the shutting down. The turned it on by pressing the power button, at the same time, pressing the F1 button multiple times. It then give me a "black" screen. I did all these with an external display connected to the lenovo t410. My type number is 2537-22U. Finally I pressed power button again to turn the computer off. Then turned power button to turn it on, it brought me directly to the external display, just like normal computer before. It is like a desktop computer with an external screen.

Difficult to do a diagnose from the distance, but most probably the screen is defective.
Can you try one more thing? Try booting with no external monitor and pressing F1, then while the screen is black use a torchlight to iluminate the screen and check if you can see the content of the screen.
