Atibtmon.exe Runtime Error When Disconnecting AC Power Cord
» Everytime I disconnect my AC power cord Windows 8 shows an 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.
atibtmon.exe is the ATI Brightness Monitor.
By default, Windows will switch to a power-saving mode when you unplug your laptop. One of the power-saving features is dimming the brightness of your laptop display. It could be that the ATI driver crashes when Windows tries to automatically adjust the brightness. Check your Windows power management settings to see if this power-saving feature is enabled on your laptop. Disabling this feature might avoid triggering the bug in the ATI driver.
A Runtime Error simply describes a problem where a piece of code cannot be loaded, or encounters an error during operation. In the case of runtime errors, the cause usually has to do with Windows rather than a specific program. A very common cause is the Visual C++ Runtime library, which is required by nearly every application that runs on Windows. Therefore we can use DLL Suite to cope with it.
It is especially useful for the daily PC Users: a totally automated free repair tool supports for the fix and free download of any .dll file, .exe file or .sys file.

At this point, as of November 2012, ATI & AMD have not acknowledged that this error exists, and no fix is available other than uninstalling your ATI Video drivers, which of course is not an option, so we will have to deal with this annoyance until ATI addresses the error in the next driver update.

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.
- JAMES REYNOLDS replied on January 25, 2013: » 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?

Power -> Power Play -> uncheck Enable Vari-Bright
- GLENN GAVINCHUK replied on January 29, 2013: » It's worked with me.
I have a Acer Aspire 5552-5664, with a ATI Mobility readeon HD 4250 and this error started when I installed the AMD vision control center in my Windows 8 Pro x64.
