Bug Description

When I run linux on my netbook lenovo s10-3c all keys are disabled, numlock, capslock... It's seems like keyboard haven't power.

keyboard works perfectly in bios, in grub (or lilo), in windows, but not in linux.

I try linux kernel 2.6.35, 2.6.36, 2.6.37-rc2 (from Natty) and upgrade BIOS up to 3CCN13WW keyboard doesn't work.

Also I try all variants for kernel opts from -- keyboard works only with 'noapic acpi=off'

add to kernel opts 'noapic acpi=off'

But battery state, powersaving, powerbutton and other useful things doesn't work.

I'm join to Boris. I have the same prb on Lenovo S10-3C.

BTW: If you will turn off wifi in "noapic acpi=off" mode, then touchpad turn off also and it doesn't work any more (the same as wi-fi) until rebot. I think that keyboard also turn off. Some later i will check it too.

Hi Boris,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

1 and GENERAL: keyboard still don't work
2: after disabling bluetooth and wi-fi by hard button on notebook, touchpad still work (it also disabled before this kernel install)
3: after turn off wifi by this button, wifi didn't turn on again by this button (the same as before)

I still must to work in "noapic acpi=off" mode

I can confirm the same bug on my Lenovo S10-3C.

The consensus on google is ACPI DSDT problems on this laptop. I tried all kernels upto and still same result no keyboard.

I have attached dmesg ACPI related error log in the hope someone is able to upload a custom dsdt which works for this laptop.

I can confirm that the following bug is now affecting the lenovo s10-3c

The latest maverick kernel update causes major problems including the following.
System Hanging on shutdown.
Wifi Card issues with the Realtek wifi card.
System stuck forever rebooting.
Also in my case It managed to cause complete system falure due to hard disk corruption.

Here is the bug report for a fyi. Since it also relates to this bug since it is cause by acpi/apic problems. Except on the S10-3t model

Jay (jskcomputerrepair) wrote :

Update #1. I have a nasty hack in place that allows you to fix this problem. In other words the keyboard is working with the acpi.

At least I have the keyboard and acpi working at the same time now.

I agree the best way to solve this is a custom DSDT.
That will take a bit of time.
Even better news Its appears from the bios dumps 3g hardware and wifi adapters are hardcoded on which ones will and will not work in the bios.

Update #2

Happy holidays to everyone. 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.

Regards and happy holidays

The same problem with my S10-3C! The keyboard doesn't work in linux! (with ACPI support)
The kernel was updated. Are there any decisions to fix it?

Seems like trouble is specific to 2.6 kernel. I tried kernels 2.4.21 (CentOS 3.9), 2.6.9 (CentOS 4.8), 2.6.18 (CentOS 5.5) - keyboard works only in kernel 2.4 on my S10-3C.

Dmitry Torokhov (dtor) wrote :

Just out of curiosity, does booting with atkbd.reset on the kernel command line gets the keyboard going? (I assume Ubuntu has atkbd built in).

I tried to use this parameter when loaded Fedora 14 and Ubuntu Netbook Remix 10.10, but keyboard was not worked (BIOS version 1.10.)

A little offtopic: freebsd 8.1 have the same trouble :(

Boris Savelev (boris-savelev) wrote :

BTW, I think that our problem is in bad-bad-bad BIOS from lenovo. If interested peoples want to solve this problem they can try to get support directly from lenovo. May be they publish new bios with fixes.

That is just to confirm S10-3C is affected by this issue, with the HW configuration distributed all over the world (no HW/SW parts specifics to Russia). Hope to see the bug fix sooner, rather then latter.

UPD, JFYI: FreeBSD 8.1 doesn't handle the problem well - booting with ACPI leave keyboard inactive, but without ACPI keyboard works like a charm.

Vladislav Alekseev (vldrus) wrote :

Alexander, did you try to install and use FreeBSD without ACPI? I think, if install FreeBSD without ACPI, we will have troubles with battery state and other, like on Linux.

- FreeBSD 8.2 RC3 doesn't work with Lenovo S10-3 ACPI;
- latest Knoppix (released Feb 2011) doesn't boot at all;
- Mint Debian (201101) same thing as with Ubuntu / others.

Hi Vlad,

no I don't. As mentioned, ACPI is the key of the issue (with no ACPI OSes are capable to boot and install), but what the heck do I need a notebook without ACPI?! :)

Mainly debugged DSDT (0 Errors, 4 Warnings) doesn't improve situation.

Is there any progress in bug fixing? Meego kernel mentioned above doesn't work for me. But I haven't yet tried to build custom kernel with Meego's config.

Also any other free OS I've tried (NetBSD/OpenBSD/FreeBSD/Plan9) is affected by this bug. Windows XP Professional falls in blue screen during setup.

Hello. I've found a workaround to this bug. If you compile and run as root programm that mentioned here ( - your keyboard will work.

I wish this will help to fix bug in the kernel or through /sys

The camera works? On my device with ubuntu 10.04 not working. Solution?

Hi! gaf mentioned above that the work around for keyboard issue was to compile and run as root program that was mentioned in ( and this was the script below;

#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;

I'm a novice and know nothing about script, please help me, can somebody provide a step by step how this program(script)

What the proper step to make so that this program will work? Please help.


Save the code as a mmm, "activate_keyboard.c", next do
   gcc activate_keyboard.c -o activate_keyboard
give the binary permissions of execution with
   chmod +x activate_keyboard
and copy activate keyboard to a location, where only root can see it, like /sbin
   sudo cp activate_keyboard /sbin/
Finally, make or edit a boot script to run this program at startup.

This says place driver to rc.local.
However, comrades report that driver should be placed to /etc/pm/power.d/ to make keyboard work after sleeping. Isn't it?

The patch works.... at least the keyboard works. Thanks everybody

The webcam works in Linux Mint 11 Katya. The Wi-fi works properly and does not disrupt poweroff in Linux Mint Debian 201101. The webcam too works in Linux Mint Debian 201101.
But even after applying the patch, the keyboard does not work after suspend/hibernate. Anyone has a solution for a newbie? Thanks

Pavel's Wi-fi activation fix did not work either (maybe because my Wi-fi hardware is RT3090). I followed the instructions at to activate Wi-fi.
But the Bluetooth still isn't working. If anyone knows how to activate it in Ubuntu 10.04/Linux Mint 9 please post.
However, my webcam has worked with every OS so far.

But a one question - how to update my BIOS with linux OS ?
All drivers from lenovo came only in windows binaries (((

Stanislav I think you have to load windows somehow. In my case, I have no possibility to do it. Please notify if there any success.

For those facing a similar problem under FreeBSD, I compiled a version of the above code and tested it on 9.0-RC3. With ACPI disabled, it functioned like described, but it has no effect when acpi is enabled. I don't know enough about the workings of OSs to hazard a guess as to why it works under Linux but not BSD, but I'd welcome any suggestions for further research.

Dmitry Ogorodnikov (dmitrybo) wrote :

Stanislav, you can use FreeDOS.

Archive with BIOS contains $BIOSVERSION_ReleseNote.doc with corresponding instruction.

You should call Lenovo support and request new BIOS, dont't download it elsewhere, even on Lenovo site, it's not the same.

This may be useful:

And yeah, new BIOS works.

There is a better workaround given by gaf.

But there is no need in workaround, just update your BIOS to version 16 or later.

Let's provide Lenovo's phone in description and close this ticket as invalid.

Boris Savelev, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 10, 2012.
Please see this document for currently supported Ubuntu releases:

We were wondering if this is still an issue in a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from .

If it remains an issue, could you run the following command in a supported release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

Please let us know your results. Thanks in advance.

Maybe there is something i'm missing beacause my poor English, i don't now.

I'll describe step by step what i've done, so please, tell what i'm not doing (or doing wrong).

1.- copy driver file s10-3c-keybdrv-x86-64 to /bin directory

2.- execute on the terminal "chmod +x /bin/s10-3c-keybdrv-x86-64"

3.- add to /etc/rc.local string before exit 0 "/bin/s10-3c-keybdrv-x86-64"
