If you have an Ideapad 100S laptop and suddenly the keyboard, touchpad and sound stopped working, then in article you'll find instructions to fix the problem.
One of the strangest problems I have encountered is that the touchpad, the keyboard, and sound do not work on a Lenovo Ideapad 100S-11IBY laptop after installing Windows 10 updates.
This particular problem is very frustrating for two reasons: First, because it makes the laptop almost unusable and second, because it is impossible to solve the problem unless you connect an external mouse.
If you're having the same problem, take a deep breath, plug in an external mouse, and follow the instructions below to bring back the keyboard, touchpad and the audio on your laptop.
How to FIX: Keyboard, Touchpad & Audio Not Working on Lenovo Ideapad 100S-11IBY in Windows 10.
1. Before proceeding with the methods below, make sure your keyboard is working and not damaged. To do this, check if your keyboard is working in BIOS setup, by following these instructions:
1. Turn off your laptop.
2. Turn on your laptop again and immediately and repeatedly press F2 or (Fn+F2) to enter in BIOS setting. (Another way to enter in BIOS setup is by pressing F12 or (Fn+F12), or by pressing the Novo button when your laptop is switched off)
3. If you can enter in BIOS setup, then navigate in BIOS settings (e.g. by using the arrow keys), to ensure that your keyboard is working and then continue to the methods below. If your keyboard does not work in the BIOS settings, skip to method-5.

a. Connect an external USB keyboard to type your password, or…by using the external USB mouse…

The next method to fix the reported problem, is to install the Intel Platform drivers for your laptop.

6. Check if the keyboard is working. If not, try the same steps, but this time open the laptop cover and disconnect the battery also. If you cannot do this, leave the laptop on until it discharges or contact a qualified technician for assistance.
