Touchpad on a Samsung Galaxy Book Flex (NP950Q) stops working

Hi,

suddenly the touchpad of my Galaxy Book Flex stopped working. The touchscreen and the S-Pen continue to work, so it is still manageable.

It happened after a Windows update, but I'm not sure if there is some relation to this (I'm now at 20H2 build 19042.685). fn-F5 key (which normally enables/disables the touchpad) does not help. fn-F11 which enables/disables Qi power transfer on the touchpad also has no effect to the touchpad usability.

There are also some other threads out there for touchpad problems with this or similar Samsung Galaxy books. They all suggest to update or reinstall the touchpad drivers. But my drivers where recent and no update was possible. A device re-scan after removing the HID device flagged with an error did not help.

This is already the second time this happens, last time I somehow solved it by playing around with the device manager. But this time it didn't help.

BTW, there is also a Linux installation on a second partition, it now also misses the touchpad. So I think something happens in the BIOS.

I'll try a little further ...

best regards

Albrecht

    Hi again,

    I now had a look into to BIOS (F2 key). Within BIOS the touchpad works! 

    Under "Advanced" you can disable/enable the touchpad. 

    I now booted once into Windows 10 with the touchpad disabled. Device manager had one HID device less.

    Then I re-enabled the touchpad in the BIOS. At the next boot the touchpad worked again under Windows 10.

    Here is a BIOS screenshot of a similar model showing the "Advanced" Tab: https://publish.samsungsimulator.com/simulator/f49460eb-b3fd-4825-afbf-eb28f3cc1060/

    Maybe it helps someone else too.

    Bye

    Meanwhile it hit me again, this time even no touchpad available in BIOS. But "disabling - rebooting - enabling - rebooting - search for new hardware" again helped me. Of course you need to navigate by keyboard through the BIOS options, maybe an USB mouse would also help.

    I have the EXACT same problem but my touchpad doesnt turn on in BIOS and disabling and enabling it again does nothing. I dont even have an option/tab for it in my normal settings! Ive done all the same steps you have and I dont want to send in my computer for maintenance…
