Everytime I disconnect my AC power cord Windows 8 shows a Erro Dialog:

Runtime Error!

Program: C:\WINDOWS\system32\atibtmon.exe

This application has requested the Runtime to terminate it in an unusual way.

Please contact the application's support team for more information.

Anyone having the same problem?

Any hotfix for this?

Unchecking the "Vari Bright" option in the ATI Catalyst Control Center resolved the issue for me as well.  It seems this option dims the brightness of the display when unplugged; however, I believe Windows also does this (or, at least it does on my Dell XPS 16).  Perhaps two programs attempting to essentially do the same thing are the cause of the atibtmon issue?

I encountered this problem with my Pavilion DV6 after upgrading to W8 64bit as well and it's more irritating than it ought to be.  For what it's worth though, I opened  the AMD Vision Engine Control Center and disabled the "Vari Bright" option under the Power tab and that seemed to fix getting the error message every time my laptop is unplugged.  Doesn't fix the underlying problem and will will decrease my unplugged-time a bit, but I can live with that.

Thanks for the legwork though, Amiarage.  Looks like we;ll need to content ourselves with waiting for ATI to fix it.

    IrikHa - Awesome answer -

    100 % correctly worked and fixed the problem exactly as you described.  Problem is now gone.

    Far better than the generic Microsoft Answer given below (what a waste of time).

    The core issue remains then to get ATI and Microsoft to acknowledge this error.

    Ignoring the issue (or not officially acknowledging it) - does not help solve the core issue.

    It's amazing to me how very stubborn large companies can be to acknowledge issues.

    Of course, they are always driven by profit and unless people won't buy their products - 

    in the end they don't really care (at all).
