Correct answers: A, B
Explanation
When troubleshooting a wireless mouse, it is important to start with the most likely and simple causes: power (batteries) and connectivity (USB dongle). These are the most common reasons for a wireless mouse not functioning and should be checked before moving on to other possibilities like drivers or hardware damage.
- A. Correct.
Low or improperly installed batteries are a common cause of wireless mouse issues. This should be checked first as it is a simple and likely cause.
- B. Correct.
If the USB dongle is not securely connected, the mouse will not communicate with the computer. Verifying this connection is essential.
- C. Incorrect.
Bluetooth settings are not relevant to most wireless mice that use a USB receiver, so this step would not typically apply in this scenario.
- D. Incorrect.
While driver updates might be necessary in some cases, they are not the first step to check when the mouse is completely unresponsive.
- E. Incorrect.
Inspecting for physical damage is valid in some cases but is less likely to be the immediate cause compared to battery or connectivity issues.
