The Dell Latitude 7340 is a premium business ultrabook built around the Intel Core i7-1365U processor, offering portability for professionals on the go. When its precision touchpad stops responding, productivity takes an immediate hit — especially when you do not have an external mouse handy.
This guide covers every reliable fix, from a quick keyboard toggle to a full driver reinstall, so you can get back to work without delay.
What Causes Touchpad Failure
Understanding the root cause saves time. These are the most common reasons the Latitude 7340 touchpad stops working:
- Fn key toggle — pressing Fn + F3 (touchpad icon) disables the touchpad silently
- Windows Update replacing the driver — a generic HID driver sometimes replaces the Dell precision driver
- Touchpad turned off in Settings — Windows 11 has a separate touchpad toggle that can get switched off
- BIOS setting changed — after a BIOS update or reset, the internal pointing device may be disabled
- Ribbon cable issue — physical loosening after a drop or heavy use can break the hardware connection
Step-by-Step Fixes
Fix 1: Use the Keyboard Shortcut
Press Fn + F3 on the Latitude 7340 to toggle the touchpad on or off. Many users accidentally disable it this way. Try pressing the combination once and test the touchpad.
Fix 2: Enable Touchpad in Windows Settings
- Go to Settings > Bluetooth & devices > Touchpad
- Confirm the Touchpad toggle is set to On
- If you use a USB mouse, enable Leave touchpad on when a mouse is connected
Fix 3: Update the Touchpad Driver
- Right-click Start and open Device Manager
- Expand Human Interface Devices
- Right-click Dell Touchpad or HID-compliant mouse and choose Update driver
- Select Search automatically for drivers and install any update found
Fix 4: Reinstall the Driver
If updating does not help, uninstall the touchpad driver entirely. In Device Manager, right-click the entry and choose Uninstall device. Restart the laptop — Windows will detect the hardware and reinstall a fresh driver automatically.

Can a Windows Update break the touchpad on Dell Latitude 7340?
Yes. Windows updates occasionally replace the Dell precision touchpad driver with a generic HID driver, causing the touchpad to stop responding. Reinstalling the Dell-specific driver from the Dell Support website resolves this.
How do I re-enable the touchpad if it was turned off in BIOS?
Restart and press F2 to enter BIOS setup. Go to System Configuration, find the Internal Pointing Device option, set it to Enabled, and press F10 to save and exit.
Does reinstalling the touchpad driver delete any settings?
No. Uninstalling and reinstalling the driver resets it to default settings, but does not remove any Windows or personal data. Your files and applications remain untouched.
My touchpad still does not work after all fixes. What next?
If the touchpad fails the built-in hardware diagnostic test (press F12 at boot), the hardware may be physically damaged. Contact Dell ProSupport for warranty service or a repair estimate.
