Lenovo IdeaPad Slim 5 family keyboard or trackpad is not working correctly

Touchpad and keyboard trouble on an IdeaPad Slim 5 is reported often enough on Lenovo's community pages that the checks are well worn. For a touchpad that stops, first see whether it is simply switched off: Settings, Bluetooth and devices, Touchpad must be On, and many IdeaPads have a function key that toggles it. Then check the driver in Device Manager and update it through Lenovo Vantage. Owners report a touchpad that works and then stops suddenly, cured temporarily by a restart, which points at a driver or a power setting; turning off Fast Startup and installing the latest BIOS helped some. A touchpad that clicks but does not move may need a hardware repair.

For the keyboard, test in the BIOS: if keys work there but not in Windows, it is a driver or filter issue. An external mouse and keyboard let you carry on while you troubleshoot. Another owner-reported cause is a Windows feature that disables the touchpad when a mouse is connected, so check Settings, Bluetooth and devices, Touchpad for the option to leave the touchpad on when a mouse is connected. If the keyboard types the wrong characters, check the input language and layout in the taskbar, which the language shortcut can change by accident. Cleaning is worth a try for a sticky key: switch the laptop off, tilt it and use short bursts of air around the keycap, since crumbs and dust prevent a key from rebounding.
