Keyboard and Mouse Not Working in New Lenovo V15 Gen4 Laptop

Does the builtin keyboard work early during the boot process (when you see the manufacturer's logo and a text telling something like "press F10 for BIOS setup")?
Did the internal keyboard already work once on that system?

Thanks for your response.

Yes, the keyboard works fine till GRUB (command line) and the mouse also works in BIOS setup. So, both these are in working condition. But the problem starts when UBUNTU (kernel) starts loading making both these two handicapped.

Regards.

I have provided the response to the question that was asked last. May I expect an response and/or resolution for the reported concern if anyone kwows about it?

Regards.

Is there anything in the system logs (e.g. sudo dmesg) about the keyboard or the mouse?
I have no idea what might cause such behaviour.

I have a similar problem. In my case it is only the keyboard that is not working.

I found that Kubuntu 22.04.1 would recognize my keyboard. You may want to try a Kubuntu/Ubuntu 22.04.1 live distribution to see if it works.

A temporary solution for me has been to select "Advanced options for Ubuntu" in GRUB, then select the "Ubuntu, with Linux 5.15.0-43-generic" kernel. This is the oldest kernel on my laptop, and selecting this kernel will allow the keyboard to work.

It looks like you can download Ubuntu 22.04.1 here: https://old-releases.ubuntu.com/releases/

You can try this and see if it gets the keyboard and mouse working.

Hello Lisa.

Thanks for your suggesstion.

I tried, but even the mentioned older version of Ubuntu i.e. 22.04.1, as you suggested, did not fix the keyboard and mouse (touchpad) problem. Suspend and microphone also fail anyways. For now, I am continuing work by attaching external keyboard and mouse. But these are significant problems from the laptop portability standpoint.

1+ same here, not working

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

To ensure that it is not a hardware related issue (refer the above thread), I installed Microsoft Windows 11 (Home) in another disk partition, and found that both keyboard and touchpad are working just fine. So, it is pretty much confirmed that is a is a Ubunutu kernel specific issue on LENOVO V15 GEN 4 AMN (AMD Ryzen 5 7520U with Radeon Graphics) laptop. Hence, I would like to draw concerned team's attention to consider this bug and provide a fix at the earliest.

"... to consider this bug and provide a fix ..."

I suggest that you create a bug report. See https://help.ubuntu.com/community/ReportingBugs

Thanks Manfred for suggesting me to create a bug report. It was done at https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-6.2/+bug/2034477.

Now I recommend that the other persons, who experience this problem, access the bug report (on the link above) and press the "also affects me" button, to confirm this bug and to show that this affect several people.

Hi Pradip Kumar

I have the same problem no changes...same touch n keyword not working while trying to install Ubuntu the problems you expressed above are accurate...I too have the Lenovo v15 ryzen 3 7000 series and graphics laptop... Have found no solution all over the internet... only the problem you have described... Feels so unlucky to have such problems to specific system.... please to respond if you found solution or alternatives to the problem

Sure, Vijay.

For the time being I am managing over an external keyboard and mouse. There was a problem on microphone, but it was resolved over stanard Ubuntu updates. But the biggest challenge for non-functional keyboard and touchpad remains the same. Though I learned that the mentioned issues can be fixed by manually upgrading the kernel available from kernel.org, but I have not tried that yet. I shall let you know once I try this. Otherwise, we simply need to wait for official upgrade from Ubuntu towards these fixes. Whenever, I have any updates, I shall post here.
