How to solve Xiaomi gaming laptop keyboard function intermittent failure

By  Sigismondo Eisenhower 2019-07-04 166 0

Recently, Xiaomi gaming laptop keyboard was found failure transitorily. We will explain the phenomenon, cause, solution and operation method of the problem in detail.

Phenomenon description

1.If the problem occurs, most keys on the keyboard doesn’t response at the same time.

2.If you turn on the computer again, or waking up after closed the lid, the function can use again.

If you have these problems above,you can continue to read this post. If your situation is different, for example, if there is no function to correct a key, you can contact customer service or have the nearest distributor repaired to determine the cause of the problem.

Justification Description

This situation is mainly caused by conflicts in firmware logic commands:

The keyboard is controlled via the EC ( Embedded Controller ). The EC has a function module for controlling the keyboard called KBC . The KBC firmware controls the function logic of the keyboard. In the KBC firmware logic, if the keyboard does not work for a certain period of time, the KBC enters power save mode and the keyboard function is temporarily disabled in power save mode. In this state, the keyboard function can be activated by touching the key and is normally used.

In some application scenarios, the KBC receives the command for power save mode (but will also need to be set to shut down status in the future). At the same time, the key is pressed to trigger the wake-up command. If the two commands occur simultaneously, the KBC is likely to be caused. As a result, the keyboard function does not respond.

When the computer is turned off and on again, or the system wakes up from sleep mode and then wakes up again, KBC automatically resets so that the keyboard function can be reset to normal.

Resolution

The technician redefines the functional logic of the KBC firmware and changes the response in various application scenarios.

We have updated a BIOS with the latest KBC firmware to help users in this situation fix the problem. You can choose the right solution according to your own situation.

● Update the BIOS yourself . To do this, follow the instructions below.
