Use and Appearance
Touchpad, as well as other pointing devices. A touchpad is a pointing device that is commonly used to control a menu “cursor” (portable electronics), a mouse “pointer” (computers), or to replace some of the keys on a keyboard. Finger movements on the surface of the device are converted into “cursor”/”pointer” movements on the screen. Touching the surface imitates clicking the mouse or keyboard keys.
Touchpads can be placed next to the keyboards of various devices: computers, laptops, electronic keyboard musical instruments, mobile devices.
Touchpads can be placed on the dashboards of household and industrial equipment, can be remote (made as separate devices connected to the computer via PS/2, USB, proprietary RMI or other), can be made transparent and placed over the display (see the. touchscreen).
The touch-sensitive surfaces of touchpads are usually rectangular with rounded corners, but there are also models with other shapes (e.g., circular). Usually the surface area of the touchpad does not exceed 50 cm².
Sometimes the problem is caused by installed drivers designed for different mouse devices. It is recommended to disable them directly in the Device Manager. There are drivers that automatically disable the touchpad on laptops, and sometimes there are just conflicts.
You should try the following:
- Under “Devices” select the mouse and right-click on the icon, so that an additional menu appears. Select the item “Delete device” in it.
Optional: it happens that the laptop battery is connected, but not charged. In this case it is worth to check the integrity of the cable and make a diagnosis of the battery.
The touchpad does not work: how to enable the touchpad (touchpad) on a laptop
Hi! I have received a few questions lately about the fact that the touchpad does not work and people are asking for help with this problem. I am on this occasion has already written an article, I will give the link below. The touchpad is useful but not for everyone. For example, many people ask to turn off the touchpad, they say, hinders when working with laptops, and especially when typing.
There are two ways to disable the touchpad on your laptop. You can use the BIOS, it’s so that to turn off the iron, and you can use a special combination of keys on the keyboard. Every notebook (probably every notebook) has a key that turns the touchpad off and on. And if you accidentally press these two keys, or other actions, the touchpad stops working. And then you get questions like touchpad doesn‘t work. How to turn on the touchpad, etc. д.
It’s really very simple, let’s look at the ways you can enable or disable the touchpad on your laptop.
Diagnose correctly installed drivers
If the above options have not helped, probably on your laptop there was a driver failure, or the necessary software is outdated or has not been updated for a long time. The corresponding driver software is necessary for any equipment connected to the PC, including video adapters, sound, network cards, printers, gamepads, etc.д.
- Open “Start”, go to “Control Panel” and select “Device Manager”;
- Click on the “Mice and other pointing devices” tab and expand it;
- In the list that opens, find the name of the touchpad (for example, Synaptics SMBus TouchPad), right-click on it, and choose “Properties” from the context menu;
- The next step is to click on the tab “Driver” and look at the lines with the date of development and version;
- Visit your notebook manufacturer’s official website, find the hardware search line and type the name of your notebook there, then open “Support”;
- Click on the “Drivers/utilities” section, specify the OS version and click OK;
- In the list that appears will be the required driver, you will need to download the assembly file to your hard drive;
- After downloading the file, run the installer and start installing the update;
- Wait until the driver reinstallation is completed and restart your PC.
Sometimes it happens that hardware errors are due to automatic updates, and Windows replaces the software without making the appropriate settings. You may see an exclamation mark at the bottom right, near the tray. In such cases you should also roll back the version of the driver to the previous one.
The touchpad is disabled
Why does the touchpad not work? The reason may be trivial. the touchpad is off.
This happens because it is accidentally deactivated in system settings or with hotkeys. It is necessary first of all to check if the touchpad is disabled due to deactivation, and only after that one should look for more serious sources of the problem.
When the touchpad does not work, the first thing to check its functionality is a combination of hotkeys. With these, the touchpad is both turned on and off.
Usually one of the hot keys is designated as Fn and is located on the keyboard next to Shift, Ctrl, Win. These combinations are different in laptops from manufacturer to manufacturer. Here are the most common ones:
- Asus. Fn F9 / Fn F7;
- Acer. Fn F7;
- Lenovo. Fn F8 / Fn F5;
- Dell. Fn F5 / Fn F3;
- Samsung. Fn F5;
- Sony. Fn F1;
- Toshiba. Fn F5.
If your laptop model is not on the suggested list or none of the combinations fit, then carefully examine the top panel of the keyboard of the device. On the keys that begin with the letter F, you will see a crossed out touchpad icon. This is the key to press along with Fn. There you will find other function commands.
There are notebook models that have a special button for the touchpad. It is usually located next to the touchpad. For example, on some HP laptops, the switch is located on the corner of the touchpad. Double tap it to turn the touchpad on or off.

If the buttons do not help, then look for the problem in the operating system settings. It is important that the corresponding Windows function is active. To do this, follow these steps:
- Open the operating system options via the start menu.
- Find and click on the devices section.
- Select “Touchpad”.
- Check if the toggle switch of the same name is active.
In this section, configure the touchpad to work in conjunction with a connected wired or wireless mouse (if necessary).
It happens that the touchscreen does not work on your notebook after visiting the BIOS. It has been configured and the touchpad may have been turned off by accident. After that the hardware is no longer active, and the system can not detect it.
What to do in this case? First of all restart the laptop, and then perform the following actions:
- Press and hold the hotkeys while switching on your notebook until the BIOS opens. The hotkeys differ depending on the laptop model. Recognize them beforehand, because you will only have a few seconds to press them when you turn them on.
- Go to “Advanced” or “Advanced Settings. Find “Internal Pointing Device.”. Use the arrows on your keyboard to do.
- If the selected item is “Disabled”, then switch it to “Enabled.
- Save your changes and restart your notebook. Press F10 and then press Enter.
I confess that I had a touchpad that stopped working on its own at one point. I did not even try to figure out why that was.к. I use my laptop as a desktop and never carry it anywhere, so I always have a mouse. As you can imagine, at one point I did need it and had to deal with the breakage. In my case, the problem was software, to be more accurate, did not match the drivers. About this and everything else, let’s consider below, in each case separately.
Enabling in Windows
To turn on the touchpad in the operating system Windows, you must go to Control Panel and select “Hardware and Sound”, and there select the tab “Mouse. Go to the “device options” tab and turn it on as in the screenshot below:
How to enable the touchpad in the BIOS
If you look at our problem in various forums, in some cases, fly BIOS settings and with them the touchpad no longer works. To turn it on in the bios, you need to find “Internal Pointing Device” and set the “Enabled” which is usually located on the “Advanced” tab.
How to activate the button: different models
If you turned it on in BIOS or made sure the touchpad is turned on you go further and try to turn it on using the special keys which are different for every model. Buttons for powering on:
- Acer Aspire FnF7
- Other Acer models. FnF6 or FnF7
- Asus FnF7 or FnF9
- Toshiba FnF5
- Dell FnF5
- Samsung FnF6 or FnF5
- Lenovo FnF5 or FnF8
- Sony Vaio FnF1
Buttons need to be pressed simultaneously. Also, your notebook may have a dedicated button next to the touchpad or a touch button in the corner of the touchpad. If there are no buttons and the combination of keys didn’t help to solve the problem, go to the next step.
How to turn on the touchpad on a notebook
In 8 out of 10 cases, the reason the touchpad doesn‘t work is that it’s turned off. To activate the touchpad you need to press a key combination that makes the touchpad work in 1 second. In any combination is sure to be present button Fn, it should be noted. Each manufacturer has its own set, so we’ve compiled the most common keyboard shortcuts.
The notebook makers at Hewlett-Packard wanted to get away from the classic combinations, and placed the button to change the touchpad activity directly on the panel itself. It is often located in the upper corner and has a special light illumination.
Some other brands have gone the same way. Press the buttons or key combination a few times, and it’s likely that the touchpad will work.
Why the touchpad does not work on the laptop. because it is disabled
Really. It’s very common for the Touchpad to be turned off. The user mistakenly thinks that there is a hardware failure or a software failure.
In my case, the touchpad on my HP notebook can not be disabled at all from the Windows keyboard. I wasn’t trying to. But some laptops have a touchpad on/off feature on the keyboard.
In this case the FN key and some function key on the keypad from F1 to F2 will be pressed. For example, on different laptops, the key combinations for turning off the touchpad are as follows:
It is worth noting that in the models described many varieties of laptops and keyboard shortcuts may differ. To check which keys to press is very easy. look for the touchpad icon on the keyboard and press it together with the Fn-key.
As I said, my model doesn‘t have the ability to turn the touchpad off or on with the keyboard keys. But on some kinds of HP laptops, the touchpad itself has a button on the top left. It should be pressed twice and the touchpad will be disabled. If anything, the button is touch-sensitive.
Some models of laptops, such as Asus have built-in software that is able to configure the mouse and touchpad. Asus Smart Gesture is capable of this. It checks the functionality of the touchpad, and if there is something wrong with it, it will point it out.
How to enable the touchpad in the laptop BIOS
Sometimes the above mentioned ways to activate your laptop’s touchpad don’t work at all. In my case, it did. no combinations, no button on the touchpad. This is a crappy model. Well, let’s look in the BIOS and check the settings.
Most of the time the way to enter the BIOS is the same on laptops. How to enter BIOS? Press any key from F1 to F12. It could also be the ESC or Del key. Check the link above or the motherboard datasheet for more information.
The touchpad option in the BIOS is usually named Internal Pointing Device and is located in the Advanced section. If it is set to Disabled it means that the touchpad is disabled. Set it to Enabled.
Press F10 key to save your BIOS settings and confirm your action.
Solution with the system software
First check that the touchpad is not disabled in the Windows settings. You will find the necessary settings in the “Mouse” section of the Control Panel.
On Windows 8 or 8.1 can also press WinQ shortcut keys and type mouse in the search box. Click on the result and in the tab “Device Settings” see if the touchpad is disabled. Turn it on if it is disabled.
Next, if in the same window, click on “Options” or “Settings”, then a window will pop up with some settings for the touchpad. Depending on the model they may be different. Now make sure that all touchpad functions are active.
Save and reboot the computer for better effect. If all these actions did not help, the problem is most likely in the drivers.
What the touchpad is
On desktop computers you can only move the arrow pointer on the screen with the mouse. The portable PC (laptop), however, is equipped with a different control device. a non-removable touchpad. Its other name is touchpad from the English word touchpad.
