Touchpad turns off when a USB mouse is connected

Keep a Windows laptop touchpad available while an external mouse is connected.

Quick diagnosis

If the touchpad returns immediately after removing the mouse, a Windows or OEM “disable while mouse is connected” policy is more likely than failed touchpad hardware.

Common symptoms

The touchpad works until a USB or wireless mouse connects.
The touchpad remains listed in Settings.
Disconnecting the mouse restores it.

Likely causes

Leave touchpad on when a mouse is connected is disabled.
An OEM touchpad utility applies an equivalent policy.
A model-specific firmware toggle disables the touchpad.

Before changing anything

Confirm the touchpad works with the external mouse disconnected.
Have keyboard navigation available.
Record the current touchpad settings.

Diagnose it in this order

1
Prove the connection trigger
Connect and disconnect the external mouse twice while testing touchpad movement.
2
Open touchpad settings
Go to Settings → Bluetooth & devices → Touchpad and expand the main touchpad control where available.
3
Enable simultaneous use
Select Leave touchpad on when a mouse is connected, or the exact OEM equivalent.
4
Check the hardware toggle
If the option is absent, consult the laptop manual for its touchpad function key or firmware setting.

Solutions

Allow touchpad use with a mouse

Enable the Windows or OEM simultaneous-use option.

Restore the model-specific touchpad toggle

Use only the shortcut or firmware option documented for the exact laptop.

Verify the fix

Type and move the pointer with both devices connected.
Restart once and confirm the touchpad remains enabled after reconnecting the mouse.

Roll back safely

• Disable simultaneous use again if palm contact becomes disruptive while using the external mouse.

When to stop and escalate

• If the touchpad also fails with every external mouse removed, continue with the laptop maker’s driver and hardware diagnostics.
