I recently replaced my pavilion dv6 3240ca mainboard with a new one that I purchased online. The difference between the two main boards are the factory board(3240ca) had a hd radeon 6370m and 4250(switchable). The new board purchased (mainboard #631082-001) uses HD radeon 6550m with the same energy saving 4250.
I am not sure which model the new board came from. In BIOS have found the Product number to be #XB531EA#ABU if that helps determining the model. Also the AMD phenom II N870 processor swapped over as both boards have the same s1 socket.
Basically when I attempt to install a driver from another dv6 3XXX series notebook(tried 3286ca graphics driver as I found out it has the 6550m/4250 combo), the AMD installer prompts windows update which detects HD radeon 5650m.
5650m is not the correct graphics card however the two are closely related. The main difference being 6550m supports directX 11 and 5650m does not. Would like to install the correct driver for my graphics card, so is there a way around windows update insalling the wrong driver??
