Re: x220 Brightness Keys Fail after Hibernate

Hey Everyone,

 

Figured I would join in the discussion.  Just got my X220 2 weeks ago, latest software/ drivers installed and I occassionaly have the issue as well.  Will bring my X220 back from Sleep (Hibernation is disabled) and the Brightness will not work.   I have Norton Internet Security 2012 installed.

 

Cheers,

 

~Novak

Issue is still here. I don't use MS Security Essential or any other antivirus/firewall software. Latest versions of all Lenovo drivers/software are installed.

Close and reopen lid helps most of time.

Is there any update on whether this issue is being worked on?  My issue stems from sleep though.  When I come back from sleep, the brigthness key does not work.

 

Thanks!

Betreff: x220 Brightness Keys Fail after Hibernate

2011-11-06, 19:50 PM

Hi everybody,

 

I have the same problem.

Nearly every time I wake up from hibernate and put the x220 onto the docking station, the keys will not work at all.

Win7, newest drivers, lenovo update.

 

Any ideas on that?

 

Best regards

Jerry

@Novak921,

If you have already update the following please drop me a private message with the info needed to get this case going with engineering.

Update checklist.

-BIOS
-Hotkey package
-Power Manager
-Power Management Driver
-Windows Update.

If problem persist despite all of the above done, I would need a your machine to be shipped in to the lab as well as previously this case has been brought up to engineering and they weren't able to replicate the problem.

I will get back to you James, Thanks for the support!

 

I didn't see that 1.23 came out so I am still running 1.22 and Lenovo update just came up with a few new updates so I will let you know if it persists after the updates.

 

Appreciate it James

I am experiencing the same thing with my X220. My wireless is also disabled and all hotkeys fail, not just brightness. I have all the latest drivers and software. The issue is also present on both Windows 7 x64 Home Premium (latest windows updates) and Ubuntu 11.04. I am unable to reproduce this issue consistently. It only happens occasionally after I resume from sleep.

Probably jynx myself but I have not had the issue since I updated to the lastest drivers and bios 1.24.  So far the issue with the brightness not working after sleep is fixed or at least better.  I'll keep everyone posted if it changes.

I updated to Bios V 1.25 and have all the latest software installed. The issue is still there (on both Windows and Linux) - are there any suggestions? I have had issues since I got the unit in August, and it is still not resolved.
