I have bought a year ago the hp4530s. Last year there were no problems but this year i wanted to clean up my laptop and install a fresh windows. Now i can't get my switchable graphics to work. There are only drivers for the 7470M and not for 6490M. I thought the new driver may be compatible even if it specifies on requirements that I must have the 7470M, but after a lot of tries i still can't solve this problem. Also I can't use the 2011 - 6490M driver because it's really old and laggy in new applications.
My Windows is 7 - 64bit version.
I would really appreciate some help. Thank you
