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.

    I've recently updated to Windows 10 and have since then noticed this "microsoft visual C+++ runtime error" everytime I unlock the power cord of my laptop. I have tried the steps you have mentioned, but when I get to this step ------>   f) On the ‘Startup’ tab, click ‘Open **Task Manager’.**In the Task Manager window under startup tab, right click on “atibtmon.exe” which are enabled and select ‘Disable’.

    There is no "atibtmon.exe" on the list and I therefore am not able to click it and disable it. This is what the notification says to error is coming from though...

    Also, I've downloaded the AMD Catalyst Control Center where lots of people mentioned going to "powerplay" and unchecking the "vari bright" option.... this is also an issue i'm having because I do not have a PowerPlay option anywhere on the program screen!

    What do i do????

    Please help me, thanks:

    I've tried all other 5 suggestions people have made on this forum and this is the only one that has worked!! I cannot thank you enough, I've been fighting to figure this out for a while now.. Just one more question.... This "AMD External Events Service" that I have disabled, is this something I need for another program or app? Is it going to disrupt any other services?

    Thanks again,

    Simone
