The opening method of a laptop touch screen (usually referring to a touchpad, not the display screen of a laptop) can be achieved through various means, depending on the brand, model, and operating system of the laptop. Here are some common ways to open: 1. Use shortcut keys to open
Most laptops provide shortcut keys to turn on or off the touchpad. These shortcut keys are typically located in the function key area (F1-F12) of the keyboard and require pressing both the Fn key and the corresponding function key simultaneously. Common combination keys include Fn+F6, Fn+F8, Fn+F9, etc., but which key depends on your laptop brand and model.
Example:
Lenovo laptops often use Fn+F6 to turn on or off the touchpad.
Huawei and HP laptops may use Fn+F8.
Some models of Xiaomi and Asus may use Fn+F9. 2、 Enable through system settings
If the shortcut keys don't work, you can try enabling the touchpad through system settings. The following are the general steps in the Windows operating system:
1. Open Settings: Click on the Start menu in the bottom left corner of Windows, and then select "Settings".
2. Select device: In the settings interface, choose the "Devices" option.
3. Click on touchpad: In the device interface, find and click on the "Touchpad" option.
4. Enable touchpad: In the touchpad settings page, ensure that the touchpad is turned on. If there is a switch option, switch it to the on state. 3、 Open through the control panel
For older versions of Windows, you may need to enable the touchpad through the Control Panel:
1. Open Control Panel: Click on the Start menu in the bottom left corner of the Windows desktop, then search and open "Control Panel".
2. Select hardware and sound: In the control panel, choose the "Hardware and Sound" option.
3. Enter Device Manager: Click on "Device Manager" to enter.
4. Find and enable touchpad: In Device Manager, find the "Mice and other pointing devices" category and expand it. Find the touchpad device (usually labeled as "Touchpad"), right-click on it, and select "Enable Device". 4、 Check the physical switch
Some laptops are also designed with physical switches to control the on and off of the touchpad. These switches are usually located on the side of the laptop or in a corner of the keyboard. If the computer has a physical switch, please check its status and ensure it is in the on position. 5、 Update driver program
If none of the above methods can solve the problem, it may be due to a faulty or outdated touchpad driver program. You can try updating the driver:
1. Enter the Device Manager.
2. Find the touchpad device and right-click on it.
3. Select 'Update Driver' and follow the prompts. 6、 Contact technical support
If none of the above methods can solve the problem, it is recommended to directly contact the after-sales customer service of the laptop or the technical personnel on the official website for assistance. They can provide more professional solutions based on specific situations.
The above methods may vary depending on the brand, model, and operating system version of the laptop. If the specific operation method cannot be determined, it is recommended to consult the computer's user manual or online support resources.
