Precautions when using the touch screen
1. When using the touch screen, be careful not to tear the surface with any sharp
objects.
2. To ensure normal use of the touch screen, ensure that both the screen surface and
your fingers are clean and dry.
3. To ensure precise positioning on the touch screen, avoid handling or touching the
glass frame when you are touching the screen.
4. Turn the computer off for safety before cleaning the screen and frame with a soft
cotton cloth. Do not wipe it with a wet cloth as this may leave a water mark and
affect touch operation.
5. Do not place or drop anything on the four corners or frame of the screen. This could
separate the screen from the frame and prevent the screen sensing properly. Please
avoid leaving water and dust in the gap between the casing and glass when you are
cleaning the frame.
6. Avoid using the touch screen in dusty environments or hot or humid conditions. Any
abrupt temperature change may cause condensation on the inside surface of the
glass screen. This condensation will disappear after a short time and does not affect
normal use.
7. Do not spray any liquid or cleaner directly onto the touch screen.
8. Do not use solvents or industrial alcohol-based cleaners.
9. Avoid using the computer in strong sunlight, which will affect the function of the
touch screen.
10. Recognition of touch gestures can be influenced by the following:

11. The touch screen does not function in Rescue System mode.
12. The touch screen also does not function during the startup process, in Hibernate
mode and in Sleep mode or Safe mode.
13. Do not touch the screen with your finger or any other objects during the computer
startup or wake up process.
