Laptop touchpad not working or cursor jumping? Fixes for Windows and Mac
The pointer won't move, scrolling stopped, or the cursor leaps across the screen while you type. Touchpads are usually switched off or confused rather than broken, but one cause needs to be taken seriously.
1. Is it switched off?
- Touchpad key: many laptops have an F-key with a touchpad icon. Some have a tiny light in the corner of the pad itself; on some HP laptops, double-tapping the top-left corner turns it on or off.
- Windows 11: Settings > Bluetooth & devices > Touchpad: turn the switch on, and expand it to tick Leave touchpad on when a mouse is connected. With that unticked, a plugged-in mouse, or a wireless dongle with the mouse switched off in a bag, silently disables the touchpad.
- If nothing works and you have no mouse, use the keyboard: press Win, type "touchpad", Enter, then Tab and Space to toggle.
- Some laptops can disable the "internal pointing device" in the BIOS / UEFI setup.
2. Drivers
Touchpads use either Windows' built-in Precision touchpad driver or a maker's driver (Synaptics, ELAN, Alps). After a Windows update the wrong one can be installed, and the pad stops working or loses gestures.
- Device Manager > Human Interface Devices and Mice and other pointing devices: look for the touchpad (it may be called I2C HID Device). A warning sign or "disabled" points to the fix.
- Right-click > Uninstall device, then restart; or install the touchpad and chipset (serial I/O, I2C) drivers from the laptop maker's support page. Roll Back Driver helps if it broke after an update.
- If the Touchpad page in Settings shows only a few options, you're on a maker's driver: its settings live in a separate app or in Mouse settings > Additional mouse settings.
3. Scrolling and gestures don't work
Settings > Touchpad > Scroll & zoom (drag two fingers to scroll, pinch to zoom) and Three-finger / Four-finger gestures. "Tap with a single finger to single-click" is under Taps. A few apps ignore Precision touchpad scrolling; if it's only one program, it's that app.
4. Cursor jumping or moving by itself
| Cause | What to try |
|---|---|
| Palm brushing the pad while typing | Settings > Touchpad > Touchpad sensitivity: set Low or Medium; maker's drivers call it palm rejection |
| Dirt, grease, damp or lotion on the pad or fingers | Wipe with a barely damp cloth, dry it, dry your hands |
| Charger causing electrical noise | If it only happens while plugged in, try the original charger, another socket, or unplug; cheap or ungrounded chargers commonly cause this |
| A second pointing device | A wireless mouse on the desk, a pen, or a touchscreen with a fault can move the pointer: unplug the dongle and test |
| Wrong or old driver | Install the maker's touchpad driver (step 2) |
| Pressure from below (see below) | Stop using the laptop |
5. Warning sign: a raised or stiff touchpad
If the touchpad has started to bulge up, won't click, clicks on its own, or the case doesn't sit flat on a table, the battery underneath may be swelling. That's a safety issue, not a settings problem: shut the laptop down, unplug it, don't press on it or charge it, keep it away from anything flammable, and get the battery replaced by a repair shop. Swollen batteries often also cause charging trouble; see laptop battery not charging. Heat speeds up battery ageing, so a laptop that runs hot all the time (overheating) is more at risk.
6. Mac trackpad
- System Settings > Trackpad: tracking speed, Tap to click, Force Click, and the Scroll & Zoom and More Gestures tabs.
- Trackpad ignored whenever a mouse is connected? System Settings > Accessibility > Pointer Control: turn off "Ignore built-in trackpad when mouse or wireless trackpad is present".
- Can't click but tracking works: a Force Touch trackpad doesn't really move; it needs power and a restart. If it's physically stiff or raised, see the battery warning above.
7. Quick test: hardware or software?
Restart the laptop and, before Windows loads, enter the BIOS / UEFI setup. Many setup screens accept the touchpad. If the pointer works there but not in Windows, it's the driver or settings. Also try a USB mouse: if it works, Windows is fine and the touchpad or its ribbon cable is the problem.

Questions
Why has my laptop touchpad stopped working?
It's usually switched off with the touchpad key or in Settings > Bluetooth & devices > Touchpad, or disabled because a mouse is connected. Turn it on and tick 'Leave touchpad on when a mouse is connected'; if that fails, reinstall the touchpad driver.
Why does my cursor jump around when I type?
Your palm is touching the pad. Lower Touchpad sensitivity to Low in Windows settings, or use the palm rejection setting in the maker's touchpad app. Clean, dry fingers and pad help too.
Why is my touchpad erratic only when charging?
Electrical noise from the charger, often a cheap or ungrounded one, interferes with the touchpad's sensing. Try the original charger, a different socket, or unplug it.
Why won't two-finger scrolling work?
Check Settings > Touchpad > Scroll & zoom. If the option is missing, a maker's driver is in charge; use its app or install the Precision touchpad or maker's latest driver.
Can a swollen battery affect the touchpad?
Yes. A swelling battery under the touchpad pushes it up, making it stiff, raised or clicking by itself. Stop using and charging the laptop and have the battery replaced.
