The Dell Inspiron 15R 1818 keyboard is out of order, external devices, touchpad are all working fine

Dell's machine has a one-click restore?

Or find a disc that comes with the machine to recover...

If none ... Then what they installed for you is also pirated If they are sure that you are genuine, and there is no one-click restore and recovery disc, you must have a sn number on your machine, generally pasted on the back, as long as you find the sn number, go buy a normal installation CD, install it yourself, enter the number pasted on your machine when installing to enter the serial number, you are genuine...

There is a bug in the Dell Inspiron series, that is, after installing online banking, it will conflict with the driver of the touchpad touchpad, resulting in the failure of the keyboard. If it's this problem, it's OK to deal with it, there's no need to make it too complicated. After uninstalling, the touchpad can be used the same, but the closed shortcut keys can't be used, in fact, it doesn't have much impact, or online banking is preferred!!

This can only wait for the dell upgrade program.

In fact, the touchpad is also very mug if it can't be turned off! Due to the design of this computer, when typing, the hand will often inevitably touch the touchpad, so the mouse often drifts, which is very annoying! The solution is to control the touchpad program and turn the touchpad off, so that it is all over the place.

Is there some software conflict?

Hello, this is caused by the conflict between the online banking plug-in and the keyboard driver.

It is recommended that you can use the method of uninstalling the touchpad driver delltouch after factory operating system reset, and then installing the online banking plug-in for temporary use.

Here's how to do a factory reset

1. Before booting into the system, press F8 to enter the advanced boot options of Windows 7 and select "Repair Computer".

2. Select the keyboard input method.

3. If there is an administrator password, you need to enter it; If you don't have a password, just "OK".

4. Once you are in the System Recovery option, select "Dell DataSafe Restore and Emergency Backup".

6. Select "Restore My Computer" and click "Next".

7. After selecting the correct factory image, click "Next" to start restoring the system to the factory state.

Note that the notebook needs to be connected to an adapter during the recovery process. When you're done, restart your computer.

The solution to the Dell computer touchpad that cannot be used is as follows:

1. If it is in use, it will fail and there is no response. This may be due to accidentally turning off the touch screen, generally press fn (function key) + f6 (different keys for different notebooks, there is a touchpad image on the button) to unlock it, and some computers also have buttons to directly open and close the touchpad.

2. You can check whether it is a driver problem. If you have reinstalled the computer, you should install the appropriate driver first, and then try to use the touchpad.

3. You can restore it through the settings, open the properties of the mouse in the control panel, you can see that there is a "device setting value" after clicking, you can see that there is a "setting value" on the interface that comes out, and an interface comes out after clicking, and you can see that there is a "touch" on the left side of the interface.

Hello, you can try to boot up and press F2 to enter the BIOS, test whether the keyboard is available under the BIOS, if it is available, it is generally not a problem with the keyboard, it should be a driver problem under the operating system.

Restart your computer to try it, or use the driver wizard to update the driver. No matter how hard it works, turn on the computer to see if the contact is not good. It's not good, maybe the keyboard is broken and can be repaired.

Maybe your laptop has a bit of a problem with its built-in keyboard.

I suggest you take it and fix it.

Or connect an external mechanical keyboard, I use it like this, take a Rapoo V720, it feels better and is more comfortable to type.

There's a trackpad lock to see if it's locked.

If nothing else, it should be the failure of the keyboard contacts caused by too many keyboard strokes or other reasons, and it is good to spend dozens of dollars to replace the keyboard after sales.

Hello, the general trackpad can be disabled, but the keyboard cannot be disabled.

In your case, the initial judgment is that you have installed some software that causes conflicts and makes the keyboard unusable.

1. The keys are stuck (press the keys one by one, whether each button has elasticity).

2. The keyboard is wet and leakage (cleaning and drying the machine board).

3. The protection elements of the longitudinal and horizontal lines of the keyboard and the anti-interference capacitor leakage and short circuit (determined by measuring the resistance to the ground or the voltage of the keyboard contact).

4. Caused by the failure of the clamshell control circuit.

5. CPU virtual soldering or bad (replanting, replacement).

6. The machine board is disconnected.

Is it loose cable, you better take it to the computer store for others to see, it's really not possible to change the keyboard.

Here are some things to try:

Open the control panel, double-click to open the "Mouse" option, turn on the "Device Settings" option, click "Disable", and confirm.

Click Start->Execution(Win+R), Enter", press Enter, open "Device Manager", go down to find "Mouse and other indicator devices", this option, find the trackpad (should be separated), right-click on it, select "Deactivate", and the trackpad is disabled.

Hello: After you need to disable or uninstall the security software on Dell Inspiron 14R, go to Dell's official website **TouchPad delltouch and quickset to reinstall and restart the computer.

This notebook doesn't have a shortcut to turn off and turn on the touchpad. It's so bad that I didn't know when I bought it. There is no such common sense function. It's annoying that F9 is a blank key, nothing, since it's useless, why not replace it with a touchpad switch.

For any notebook, the way to turn off the touchpad is the same.

Closing method: 1. Right-click "Computer" and click "Properties";

2. Select "Device Manager", find the touchpad, and right-click "Disable" to turn it off.

Hello, you first need to install the relevant drivers correctly, and then you can use the shortcut keys to switch, generally FN+F3 (specific to the logo on your machine keyboard).

Hello, please provide your computer's service code for further verification of your model, the service code is located on the long strip label at the bottom of the fuselage, consisting of 7 digits of English + numbers. At the same time, please describe the problem in detail, so that you can propose targeted solutions according to your model and problems.

Generally, notebooks will have shortcut keys to control, press FN first and then turn off the touchpad according to the icon on the F1-F12 keys, provided that the shortcut driver of the official website is installed.

You can also disable the trackpad directly, go to the device manager, find the touchpad driver and disable it.

The Dell 5437 notebook can turn off the touchpad in two ways:

Use the shortcut keys FN+F3 to quickly turn the touchpad on or off. The prerequisite is that the computer must have the FN hotkey driver installed.

Switch in the control panel: open the control panel, because the touchpad controls the mouse, so find the mouse option in the control panel and click the mouse. In the open mouse properties, there is a device setting value option, select the device settings column, find a touchpad, disable it.

Once the disabling is successful, tap on the app and you'll find that the touchpad is no longer working. If you want to turn it on again, click Enable next to Disable, and click on the app directly after the activation is successful.

Shortcut key FN+F9 to turn on and off the touchpad!!

It's normal under PE or DOS, if it's normal, it's a system problem, just make a system.
