Hello
I have a Lenovo thinkpad t410. I installed centos 6.3 - after a few days the screen got inverted. I have tried rebooting, power cycling -- even booting off a ubuntu CD but the screen remains inverted. I have tried alt+ctrl (up arrow) and (down arrow) to no avail.
Its inverted as soon as I boot it up. I even tried to put the install CD but the screen is inverted as soon as I boot up the laptop. The system never seems to come to a login prompt. Tried power cycling.
With the install CD I get the inverted menu but am not able to get a prompt even if I hit "enter" key to the first install question (where it asks for the language).
I tried several power cycles with no avail.

Re: lenovo thinkpad t410 screen inverted
If the screen image is upside down when you see the BIOS messages then this is not a CentOS problem but rather one with the hardware or firmware itself. You need to ask Lenovo or someone familiar with their hardware for a solution.
Re: lenovo thinkpad t410 screen inverted
I realize it is possibly not a 'centos problem' but I am sure someone must have run into this problem. The problem did not occur with windows which I ran for over 2 years but popped after I installed centos.
Here is what happens. The laptop is loaded with centos 6.3 but I have tried it with an install CD running fedora
1. As soon as I power cycle/reboot it the first prompt is an inverted "centos 6.3" bootup sequence
2. The screen stays inverted - while the bootup is going on
3. After a minute or so the screen starts to gray out but gets brighter and the letters on the screen are not readable
4. It stays like this - if I power cycle same thing happens
A little history
The laptop ran windows 7 for 2 years with no problem. I loaded centos 6.3 - initially the system up fine - ie I was able to access internet with a browser, with no problem. The after a day or 2 the screen started to get inverted once in a while. Based on suggestion I tried to revert the screen back with "ctrl" + "alt" " up arrow" or "down arrow" . I believe it may have worked once or twice but not consistently. A reboot took care of the prolem once or twice.
However, the problem became consistent and now it is impossible to get the screen normal.
I tried to boot up the laptop with 1) centos install CD 2) fedora install CD. However, the problem is still the same.
I have tried power cycling, removing battery. One thing I have not tried is replacing the memory stick.
COuld this be a problem with the graphic card setting? Are there video/graphic card diagnostics?

lenovo thinkpad t410 screen inverted
The first thing I would suggest you try is to enter the BIOS as soon as the system has been powered on and before the OS loads. Is that displayed correctly?
Re: lenovo thinkpad t410 screen inverted
unfortunately its not displayed properly -- from the moment the laptop is powered on - the screen display is inverted. After a period of time the screen gets grayed out and gets brighter to the point where all the displays (or letters)are not readable

Re: lenovo thinkpad t410 screen inverted
Then, unfortunately, you are suffering from a definite hardware defect. No amount of software adjustment will make any difference.
You really need to take (or send) that system to a qualified service centre. :-(
