Introduction

When you move the mouse, the cursor does not move as expected and has a delayed response. Follow these steps to get the mouse up and running.

Causes

1

Optical Sensor Obstructed or Dirty

If the Alienware AW620M has an obstructed sensor it will inhibit the mouse’s response time. Before cleaning the sensor, turn off your computer and disconnect the Alienware AW620M. Locate the optical sensor on the bottom center of the device. Gently clean the sensor with a clean microfiber cloth, a cotton swab, or a can of compressed air.

2

Wireless Dongle Interference

Wireless interference on the USB wireless dongle may cause cursor lagging. Use the dongle extender to connect the USB dongle to the laptop or desktop.

3

USB Port Damaged

A damaged USB port can cause an improper connection between the mouse and computer and cause a jumpy and delayed cursor response. In wired mode, connect the USB charging cable to another USB port, then wait for a notification indicating the driver installation is complete before using the mouse. In wireless mode, connect the USB wireless dongle to another USB port or connect the USB wireless dongle and USB charging cable to the dongle extender. Wait for a notification indicating the driver installation is complete before using the mouse. If the USB port is physically damaged, it will need to be replaced.

4

Battery Damaged

A damaged battery can cause a jumpy or delayed cursor response. Before replacing the Alienware AW620M battery, it is important to be sure that you are replacing it with the same or equivalent type of battery. Failure to do so can result in hazardous situations.
