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. Any ideas?

Yes its inverted as soon as I boot it up. I even tried to put the install CD (incl ubuntu one) 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.

Have you tried uninstalling Centos 6.3 and doing a System Restore to a date preceding it?
Also, an upside down computer screen can sometimes be fixed by going into the "Control Panel" and rotating the image. Sometimes, this can be associated with a webcam if you have one installed.

The problem is the screen is inverted from the bootup sequence and never quiet "recovers" to a system prompt. It stays inverted. I inserted an "install CD" but the installation menu comes up inverted and does not 'accept" any key stroke (such as "enter") from me.
I even tried an ubuntu install CD with similar results.

Are you saying it never finishes loading Windows, even inverted? If that's the case,you may have to restore using the F11 option at first boot screen.

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?

While I am waiting for a new LCD I decided to try an externla monitor... however, I ran into the problem where while the display is correct on the external monitor a Dell monitor (17") - the screen goes blan after a minute or 2 during the bootup of centos 6.3. Right now I am trying to get version of ernel tht apparently solves this problem which appears to be 188.8.131.529.2.1.el6.centos.plus.i686 Is there way to get a "full" centos build via download that has this ernel bundled in. I am unable to run yum.
