Hi, I was wondering if anyone else had problems with this model. This laptop screen wiil flicker and sometimes go black and the screen wont come back on unless you plug the unit back in also starts making low humming noise when this happens and also black spots in screen . There are also other things this does that im not sure are related when playing video and you plugin or unplug laptop and there is long delay and it makes fast ticking noice. Another thing was when i hookup this to my flat screen tv with hdmi or vga the images of video are very distorted but there fine with my old Thinkpad R40E 2004 that im sure will outlast this computer. I got this back from warranty depot yesterday and they said they fixed the transformation and lighting and then tested fine. they had it for a week and came back with same problem so it is going back. I was wondering if it comes back after another week with same problem if anyone here has delt with lenovo warranty and how hard it is to get lenovo to replace the system Thanks in advance for any answers.
