On my Lenovo S10-3C the Keyboard works right up until the kernel loads. It also works if I enable "noapic acpi=off" while in Grub. Unfortunately this also creates a basically unusable system as the graphics drivers for the laptop require ACPI
on 2.6.38 don't work too
I confirm this bug on lenovo s10-3c. Built-in keyboard and ACPI don't work together.
2.6.38 - interesting thing: waking up from suspend by pressing the keyboard button works, but then the keyboard still not working
I would like to point out the other bug trackers that were tracking this until we were referred here. http://bugs.gentoo.org/show_bug.cgi?id=355627 and https://bugs.launchpad.net/gentoo/+bug/677633 Internal keyboard works sometimes when the enter key is pressed on an an external USB keyboard repeatedly while the kernel is loading. -- Though it is not practical for a netbook user to be carting around a USB keyboard everywhere they go ;-)

On my Lenovo S10-3C the Keyboard works right up until the kernel loads. It also works if I enable "noapic acpi=off" while in Grub. Unfortunately this also creates a basically unusable system as the graphics drivers for the laptop require ACPI. I am able to login with SSH or use a USB keyboard, so if you need any type of logs then let me know what I should get for you. I am using gentoo-sources 2.6.37 . Reproducible: Always Steps to Reproduce: 1.Get Lenovo S10-3C - boot Linux 2.Keyboard stops working after Grub.(all built in KB response stops, Caps lock does not light up) Actual Results: Keyboard doesn't work when apic and acpi are enabled.(all built in KB response stops, Caps lock does not light up) Expected Results: Keyboard should work with apic and acpi enabled. Additional Notes: Repeatedly hitting <enter> on an attached USB keyboard while the kernel is loading will sometimes activate the KB, sometimes not, and sometimes crash the boot process causing automatic reboot. (not a good option for a digital nomad like myself who got a netbook cause it is small) On the ubuntu bug tracker Jay said: --- The problem is located in atkbd.c . It was fixed a long time ago. I will get with them after the new year and see if they will patch it since it affects a project they are working on. If you would like to see both the acpi and the keyboard workiing. The new unbuntu kernel update has issues with these laptops. Use the stock kernel 2.6.35-22-generic add the following to the grub boot line. You need to attach a external keyboard. apm=power-off nomce vga=771 intel_idle.max_cstate=0 Now once you boot with a external keyboard attached keep tapping the enterkey <This is very important it creates a response from the atkdb which initializes the internal and external keyboard. It may be a little bit flaky with the unbuntu kernel. Your system may reboot a couple of times. This has been fixed in the test kernel. It works just fine with the stock knoppix 6.2.1 kernel. If you would like to test it out without reinstalling anything. --- Hope this helps someone get started on this!

Doesn't work in 2.6.39 either.

I've tried to compile kernel with ATKBD and i8042 as modules, but in vain. Also, any other free OS kernels (I've tried NetBSD/OpenBSD/FreeBSD/Plan9) are not capable of working with this keyboard adn ACPI enabled. All of suggested boot parameters cannot help me.
There is some version of Meego that works with this laptop. Can anyone look how it it configured?
> Where is this patch? I'm afraid I was quoting a person on a different forum. I have yet to see an actual patch. The only partial solution I have found is to buy one of those USB number pads/USB keyboards. And if you repeatedly hit Enter key on the USB keyboard while the kernel is loading then sometimes you get the internal keyboard to work with acpi and you can disconnect the USB device without trouble. Really though, it is a pain, and it usually takes several tries to work.

I've seen exactly S10-3c shipped with Meego. Unfortunately, I don't know what version of Meego it was. > And if you repeatedly hit Enter key on the USB keyboard > while the kernel is loading then sometimes you get the internal keyboard to > work with acpi and you can disconnect the USB device without trouble. Interesting fact.
Meego Linuxcenter Edition has the same problem, but some people say that it is Meego edition S10-3c shipped with. May be it needs some configuration.
http://blog.yjl.im/2010/08/disable-laptop-ps2-at-keyboard-i8042.html the problem is here. This code did a thing: #include <unistd.h> #include <sys/io.h> #define I8042_COMMAND_REG 0x64 int main(int argc, char *argv[]) { char data = 0xae; // enable keyboard ioperm(I8042_COMMAND_REG, 1, 1); if (argc == 2 && argv[1][0] == '0') data = 0xad; // disable keyboard outb(data, I8042_COMMAND_REG); return 0; }

We need some beer to thank
I can confirm that fix worked for me :D I just set up an init script that called that program and now I have the internal keyboard working with ACPI on boot :)
