Re: [SOLVED] Lenovo ThinkPad X230: Certain ACPI events can stop being sent

It is weird that it affects some acpi events but not others e.g. events from some buttons but not others. Is there any principled difference between the two groups?

The events that fail include all the "important" ones (e.g., sleep button, lid close/wake), but also ones such as the lock button.  There's no hard difference that I can discern between the groups.

You may find a workaround in this bug report I was involved with awhile back.  See comments #12 and #13.

Re: [SOLVED] Lenovo ThinkPad X230: Certain ACPI events can stop being sent

Does the same thing happen if you boot a live linux distro? (Arch or even something completely different, with maybe a different DE etc.?)

Does resetting BIOS to defaults affect the issue?

I guess you have UEFI? Does it make a difference whether you boot in EFI mode or BIOS legacy? (I'm assuming Windows is booting in legacy mode, wondering about Arch...)

I know somebody said they'd updated the BIOS but have you checked whether you have the latest? I didn't even realise there'd been a second update for mine until somebody mentioned it in a thread the other day. (Tempted to say Lenovo have picked up a trick from Apple: why pay testers when you get all the testing you need after selling the product?)

Re: [SOLVED] Lenovo ThinkPad X230: Certain ACPI events can stop being sent

It looks like this issue was fixed with the upgrade from kernel 3.4.x to 3.5.x; I haven't seen the problem since.

If I don't see the problem recur in the next couple of weeks, I'm going to mark this one [SOLVED].

Thanks for the tips and advice!  :-)

Are you using BIOS or EFI?

Because I still have the problem that ACPI often events aren't sent, when my thinkpad runs on battery. Should I try switching from BIOS to EFI?

Re: [SOLVED] Lenovo ThinkPad X230: Certain ACPI events can stop being sent

I haven't seen any issues on my x230 using BIOS. I haven't ever had a problem with sleep / suspend / resume / AC.  One thing to note is that my x230 won't charge if the battery is above 95%. This freaked me out the first time I installed it.

Re: [SOLVED] Lenovo ThinkPad X230: Certain ACPI events can stop being sent

I have not noticed any problems. I boot with BIOS and grub2-bios bootloader
My BIOS settings is left to the default to support both Legacy and UEFI.

I have only ever used kernels...
3.5.3-6-grsec, 3.5.3-7-grsec, 3.5.4-1-grsec, 3.5.4-3-grsec, 3.5.4-5-grsec

Is there a specific set of actions I should take to see of my laptop really dose not suffer from the same problems as yours?

earsplit:
Owe ya, it will not start charging your battery if it is only at 95% to protect your battery from unnecessary wear and tear. Li-Ion batteries need extra high power to charge them the last bit, which is needless wear for only 5% of battery life. However, if it is below 95% it should be charging it all the  way up to 100%.
