not a malfunction. The afterimage will disappear when a different screen is displayed.
High-precision and advanced technologies are necessary in the production of color liquid
crystal displays (color LCDs). Therefore, if 0.002% or less of the picture elements either fail
to light or remain constantly lit (that is, more than 99.998% of elements are functioning
properly), no defect is considered to exist.
Select [Start] - [Settings] - [Control Panel] - [Mouse] - [Motion] and add the check mark
for [Show trails].
When the Microsoft ® IntelliMouse TM Wheel mode or the original mode is set for the touch
pad, only scroll operations are possible for the right part or bottom part of the touch pad. In
this case, cursor operations are possible by using the work surface excluding the right part or
bottom part. When no mode is set, the entire surface of the touch pad can be used for cursor
operations. (
