Lenovo Thinkpad R400 - horizontal line problem at the bottom of display lcd

2016-06-23, 19:51 PM

Hi Everyone!

I'm Mariano from Argentina! this is my first post! everything alright?


I write this to tell my problem or detail: i recently purchased a used Lenovo R400 Thinkpad that i like very much, i love the look, characteristics, processor, is very good, i put it 4gb of ram, it goes really well, i paid it very cheap. 

But I have a little problem (the seller told me about it and show me the thing): the display (lcd) shows a little horizontal line that comes and goes (3 seconds in, and 3 seconds  out), is on the bottom on the screen, but the machine is working great, the rest of the screen is working absolutely amazing, no problem at all, it's only that line that comes and goes, is a little detail (sometimes you see it and sometimes you can't even realize that is there), i take the display off but is not the flex i guess, i move it, and is not a question of move it... the question is: anyone knows what exactly is? and how can i take it off?

If anyone can help me i would be pleased with that... 


Thanks very much guys!

Welcome to the forum!


Which operating system are you using? Are you sure you have the most updated drivers?


You can also try the following, when the lines appears or starts to flicker, gently press the bezel on the lower part of the screen and check if something happens, try the same on the upper part and let us know the results.
