i tried everything in the post but no use still doesn't work the only thing i didn't do to install a moded bios to disable the intel card and enable the ati card is that possible

 

[hamo442002]

i tried everything in the post but no good
the only thing i didn't try to install moded bios which have the option to disable intel and enable ati if that exist or make the swiching mode is fixed not dynamic
and thank you very much for caring

 

[maxie]

No i do not think a BIOS Update would help ...

 

[hamo442002]

so what to do pleas ?

 

[maxie]

I doubt that there is any Fix you seem to have tried every thing possible ...

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.

 

[hamo442002]

it means there is no hope
thx for your care

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
