Black area shown on T60 LCD, what's wrong?

[tamujun]

Hi guys,

Tonight while I was working on my T60, I noticed a small black area appeared on the left edge of the screen. Initially it was like a half circle but eventually shrinked to a smaller one. see the picture I captured from the screen:

After saving the picture, I then restarted system, the problem disappeared...

My T60 screen is 14 inch WXGA. I bought this thinkpad last Nov. So still in its waranty. Should I ask IBM or Lenovo for an inspection? Anybody encounters same problem??

Thanks for your advice.

After posting this, I found another one shown on different location. same size!!

If I start any program, it will show up; but if close the program and refresh desktop, it goes away....

LCD panels sometimes produce odd effects. I recently had 3 dark blue blobs which were only visible when the screen background was black. The panel was replaced under warranty.

If your black area persists, you'd better contact Lenovo.

It seems like the black blob was casued by a particular program, everytime I run it, a blob was shown on the screen, and changes position each time -- this might indicate the blob is not a hardware problem...

So I deleted the program. So far I haven't seen any blob (knocking the wood!!).. will keep an eye and report back.

Thanks for your response!
