- ๐จ In Device Manager, the keyboard is displayed with an error (code 10, 19 or 43)
- ๐จ Lighting flashes or works intermittently
- ๐จ The laptop does not respond to the pressing of some keys

1. Open Options โ Update and Security โ Recovery
2.Click Return the computer to its original state โSave my files
3. After reset, install the drivers manually (see Section 4)3. Activation through the command line
For advanced users: you can try to force the backlight through WMI (does not work on all models):
1. Launch the command line on behalf of the administrator
2 Enter:
wmic /namespace:\\root\wmi path MSAcpi_ThermalZoneTemperature get CurrentTemperature
(This is a ACPI- Management Support Check)
3. If the command is executed without errors, try:
echo 1 > /sys/class/leds/smc::kbd_backlight/brightness
(for Linux systems or WSL)
