Thinkpads Forum

Hi,

My machine is barely 20 days old.. and the machine's great except for one irritating thing. There keeps appearing white dots.. dead pixels and after a few hours they dissapear.

From your experience.. Do you know if this sort of thing is going to aggravate later .... and If I should get my TFT exchanged?

Im concerned as my work is all graphic and I cant have these meddlesome dead pixels hanging around on my screen.

your advice will be much appreciated.
Thanks

They might be stuck pixels. Try to download this video to flash the screen for at least a couple of hours to see if they will be fixed.

Personally I would suggest you to take advantage of Lenovo's return policy. If they don't charge too much, send it back. You never know if those defective pixels can be fixed permanently, and it would cost much more to replace the LCD later, if someday you find you can no longer live with them.

Make sure you are not experiencing the Ultranav bug.

I HATE dead pixels with a passion lol...There is a "dead pixel policy", where, depending on the resolution of your LCD, it can have up to 11 dead pixels (using UXGA as an example), they don't have to replace it. However, IBM had always been extremely liberal, and basically ignored this policy more or less. I don't know if Lenovo will do the same.

if they are random and intermittent then there's a very good chance that it's caused by software and not the hardware.   are the stuck pixels random or does this happen to the same pixels every time?

in the event that this is a hardware issue...

Do they appear when in the BIOS? If so they are probably really stuck. If not they are almost certainly a software issue.
