Maxie is pretty much correct. The only fix I have ever found with AMD cards is to disable the dedicated card. All of your graphics run through the CPU (thus the Intel graphics). The CPU decides when to switch and which one to switch to. So, your options are at least limited, but practically there is only one option.

but from what i understand my laptob uses dynamic mode and every dynamic mode can be switched to fixed mode not the oppesite because in fixed mode this problem doesn't exist so howa can i change to fixed mode it related to openGl on the card which i don't have in my 4540s
