Acer Nitro V 15 keyboard or trackpad is not working correctly

Keyboard and trackpad faults on a Nitro V15 split into software and hardware, and the test is simple: if the keyboard works in the BIOS (press F2 at the logo and use the arrow keys) but not in Windows, the cause is a driver or a setting, and if it fails in the BIOS too, it is hardware. For a trackpad that does not respond, check that it has not been turned off, which on many Acer laptops is a function key or a setting under Bluetooth and devices, Touchpad. Uninstall the touchpad driver from Device Manager and restart to rebuild it, and check for Windows updates.

Keys that stick or repeat may have debris under them. A keyboard that does nothing after a spill is a hardware repair. If the Nitro Sense utility is buggy, as one owner reported, a reinstall of Nitro Sense from Acer is the fix. If a few keys stop working, look at whether they share a row or column, since a pattern suggests the keyboard cable or a liquid spill, while random single keys suggest debris. A laptop with an external USB keyboard that works normally is proof that Windows and the board are fine and only the built-in keyboard is at fault.
