A trackpad that has gone completely dead — no cursor movement, no clicks, nothing — feels alarming, but it's one of the more methodically diagnosable laptop faults because the list of possible causes is short and each one is easy to test in turn. This guide walks through that list in the order you should check it, from the most common and easiest fix through to the physical repairs that need the case opened.

Pro tip: Before doing anything else, plug in a USB or Bluetooth mouse. This confirms the laptop itself is otherwise working normally and lets you navigate the fixes below without fighting a dead cursor at the same time.

Step 1: Check for an Accidental Disable

Almost every laptop has a way to disable the trackpad, usually intended for when an external mouse is connected, and it's very easy to trigger by accident.

  1. Look for a dedicated function key with a trackpad icon (often on F5, F6, F7, or F9 depending on the manufacturer) and press it in combination with the Fn key. On many laptops this toggles the trackpad on and off, sometimes with a small on-screen notification confirming the change.
  2. Some manufacturers (notably many older HP and Dell models) place a small physical button or LED indicator in the top-left corner of the trackpad itself — double-tap it to toggle the pad on and off.
  3. Check whether an external mouse is or was recently connected. Many laptops, by manufacturer utility or Windows setting, are configured to automatically disable the internal trackpad whenever an external mouse is plugged in, and this setting can persist confusingly after the mouse is removed if the utility doesn't detect the disconnection properly.

Step 2: Check Windows Settings

  1. Go to Settings > Bluetooth & devices > Touchpad and confirm the master toggle at the top is switched On.
  2. If the whole Touchpad settings page is greyed out or missing entirely, this usually indicates Windows isn't detecting the trackpad as a valid HID (Human Interface Device) at all, pointing towards a driver or hardware fault rather than a setting — skip ahead to Step 4.
  3. Open Control Panel > Mouse (search "Mouse" in the Start menu), and check for a manufacturer-specific tab (such as "Device Settings" on Synaptics/Elan-based systems) which sometimes has its own separate enable/disable toggle independent of the main Windows settings page.

Step 3: Check macOS Settings

  1. Go to System Settings > Trackpad and confirm the settings page loads and shows live indicators when you touch the trackpad.
  2. Check System Settings > Accessibility > Pointer Control > Trackpad Options and confirm Ignore built-in trackpad when mouse or wireless trackpad is present isn't ticked, particularly if you have a Bluetooth mouse paired even if it's not currently in use.
  3. If the trackpad settings page fails to load or shows no response to touch at all, this points to a hardware or driver-level fault — proceed to Step 4.

Step 4: Driver-Level Diagnosis (Windows)

  1. Open Device Manager (right-click the Start button and select it), then expand Mice and other pointing devices.
  2. Look for your trackpad listed as something like "HID-compliant mouse," "Synaptics," "Elan Input Device," or similar. A yellow warning triangle indicates a driver problem; if the device is missing from the list entirely, Windows isn't detecting the hardware at all.
  3. If present with a warning icon, right-click and select Uninstall device, tick Attempt to remove the driver for this device if offered, then restart — Windows will attempt to reinstall a default driver on boot.
  4. If missing entirely, check Device Manager > View > Show hidden devices, since a disconnected device sometimes remains listed as greyed out here, which can confirm whether Windows has ever seen it since the fault started.
  5. Visit the laptop manufacturer's support page, search your exact model number, and download the specific touchpad/precision touchpad driver rather than relying solely on Windows Update, which sometimes installs a generic driver that doesn't expose all functionality or, in rarer cases, doesn't load correctly at all.

Step 5: Rule Out a Recent Software Change

If the trackpad worked before a specific event — a Windows Update, a new application install, or a macOS update — a recent change is a likely trigger.

  • Windows: Use System Restore (search "Create a restore point," then click System Restore…) to roll back to a point before the fault began, if a restore point exists from that time.
  • macOS: Check System Settings > General > Software Update for a pending update that might resolve a known regression, since Apple does periodically ship trackpad-related fixes in point updates after a wider issue is identified.

Step 6: Physical Investigation

If software and drivers check out clean and the trackpad still shows zero response, the fault is very likely the ribbon cable connection or the trackpad module itself.

  1. Power off completely, disconnect the charger, and if possible remove the battery.
  2. Ground yourself against static (touch an unpainted metal surface or use an anti-static wrist strap) and open the base cover following your model's service manual.
  3. Locate the trackpad's ribbon cable connector — usually a small ZIF socket either directly beneath the trackpad or routed to the motherboard, sometimes via the keyboard's connector board on machines where the keyboard and trackpad share a hub.
  4. Check the cable is fully seated: lift the small locking flap, reseat the ribbon fully into the socket, and press the flap back down firmly. A cable that has worked loose from vibration, a drop, or simply the flex of opening and closing the lid thousands of times is one of the single most common causes of a trackpad going completely dead.
  5. Inspect the ribbon itself for tears, creases, or discolouration at the fold points, which indicate physical damage requiring a replacement cable rather than a reseat.

Safety warning: Always fully power down and disconnect the battery before opening the case. Reseating a cable with the system live risks a short circuit and can damage the motherboard, not just the trackpad.

When to Replace the Trackpad

If the ribbon cable is confirmed properly seated and undamaged, but the trackpad remains completely unresponsive, the trackpad module itself has likely failed and needs replacing. This is a moderate-difficulty repair on most laptops — often requiring removal of the keyboard or palm rest to access mounting screws — and replacement trackpad assemblies typically cost £10–£35 for the part. If you've never opened a laptop before, this is a reasonable first repair to attempt with a service manual to hand, since the trackpad itself carries little risk to other components as long as you handle the ribbon cables carefully.
