The thin-film transistor (TFT) liquid crystal display (LCD) for notebook computers contains many TFTs. The presence of a small number of missing, discolored, or lit all the time dots or pixels is characteristic of TFT LCD technology due to manufacturing process for such technology irrespective of manufacturer.
If your LCD has 2 or less visible defective pixels, it should not be considered faulty. However, if your LCD has 3 or more visible defective pixels, it will be deemed as defective by Lenovo and is replaceable upon request, if within the warranty period.
This policy applies for all ThinkPad computers purchased starting Jan 1, 2008. Please contact your Lenovo Service representative for further assistance.
