Problem with key and trackpoint markings on the display
Contents
Problem Description
You may discover markings on your display that match the positions of the TrackPoint or/and some of the keys.
This is a known phenomena that is caused by the display having contact with the TrackPoint or keyboard. The input elements of your ThinkPad gather oil from your fingers. When you carry your ThinkPad around with the display closed, i.e. in a bag, it is very likely and normal, that the display is exposed to small amounts of pressure. Since the space between display panel and keyboard is very tiny, it can happen that they have contact. In that case, parts of the oil on your keys and TrackPoint are transferred to the display. If this happens often, you get harder to remove markings on the display.
Affected Models
- all models except TransNote and X41 Tablet
Solutions
Prevention
You can avoid getting these markings by putting a very thin layer of textile or paper between your keyboard and the display before closing it. Take care that the layer you put in between is thin enough to not put pressure on the display panel.
Removal
- Wipe the display gently with a soft patch of dry, lint-free textile.
- If the markings are too resistant, moisten the textile with LCD-Cleaner. If you don't have LCD-Cleaner, water is ok, as well, but don't wetten the textile, you don't want any liquid to drop or flow into the casing. Remember to wipe the display dry afterwards.
- If the markings still resist, DON'T increase the pressure, but be patient and wipe longer. Switching between moist and dry wiping might help as well.
