Dear Lydia Watkins!
Welcome to the Microsoft Community!
Don't worry, I will help you solve the problem together.
I understand your problem. Based on the information you provided, I understand that your touchpad stopped working after connecting an external wireless mouse. Let me give you some suggestions to solve this problem:
1. Check HP PC Manager (if your computer has it):
Open HP PC Manager and run the hardware self-test function. This can help you confirm whether there are other hardware problems.
2. Check the shortcut key:
Many laptops have a shortcut key for turning on/off the touchpad. Usually, it is a combination of the Fn key plus an F key. Check your laptop manual to find the specific shortcut key that controls the touchpad and then try to use it to turn on the touchpad.
3. Check the touchpad function in BIOS:
Restart the computer and enter the BIOS setup. Check in BIOS to see if the touchpad works properly. This can help us determine whether it is a hardware problem or a software problem.
4. Test in safe mode:
Try to start Windows in safe mode and test whether the touchpad works. If it works in safe mode, the problem may be caused by a driver conflict.
To enter safe mode: You can force Windows to boot into the Windows Recovery Environment by intentionally forcing your computer to shut down several times during the boot process.
After two or three consecutive failed attempts, Windows will automatically launch WinRE and provide access to Advanced Startup Options. To do this:
Shut down your computer.
Press the power button to power on your computer.
When it starts to load, press and hold the power button to force a shutdown. Repeat these steps to suddenly shut down the computer again.
On the third try, press the power button to let Windows load and boot into the Windows Recovery Environment.
Under Choose an option, click Troubleshoot.
Then go to Advanced options > Startup settings > Restart.
After restarting, press 4, 5, or 6 to boot into safe mode with different options.
5. Driver conflict check:
If none of the above steps can solve the problem, there may be a driver conflict. Try uninstalling the driver for the Tenmos mouse and then reinstalling the touchpad driver.
6. Contact HP Support:
If the problem persists, it is recommended to contact HP customer support. They may have a solution for your specific model of laptop.
Please try these methods step by step, and feel free to let me know if any step is unclear or requires more detailed guidance. We will continue to work hard to find a solution.
I hope above information can help you. If you have any questions, please feel free to let me know. Tell me the results. I'm looking forward to hearing from you. Thank you for your understanding and support!
