Problem: Keyboard or mouse intermittently stops responding or takes a long time
to respond.
Troubleshooting and problem resolution:
1. Check for signal interference.
Avoid putting metal objects between the device and the computer. Do not
place the computer under a metal surface or table. Move cordless phone base
stations, microwave ovens, and other 2.4GHz electrical devices away from the
computer. Keep wireless devices within 10 meters (33 feet) of the computer.
2. Download the latest version of the device drivers.
You can download the latest drivers from the official Lenovo website at
http://www.lenovo.com.
Problem: Mouse does not work as expected (pointer jittery, jumpy, slow or fast;
mouse buttons not working properly).
Troubleshooting and problem resolution:
1. Change the mouse properties to adjust pointer movement speed.
2. Try using a different surface to see if the mouse’s performance improves
(Recommend to use a mouse pad).
3. Turn the mouse over and check the sensor window. If there is any dust or
debris, clean the sensor window gently.
4. If multiple Bluetooth wireless devices are in use nearby, try turning them off to
see if performance improves.
