Issues with Laptop GPU(s)
Sorry to the mods for the double post on the same issue (posted a thread originally in H/A), but I might have more success here.
I recently bought a Samsung Series 7 laptop off ebay. I got it a few days ago, and it looks great! My BIG problem with it though is that it came with two video cards (onboard and a ATI Radeon 6490M HD), and only one seems to work. I first noticed this when I used DxDiag to check the computers specs. For some reason, the computer will only recognize the Intel HD Graphics Family chip. I've ran through the following steps to try and fix this issue:
1.) I tried to update my drivers. This was done before I got the computer and everything is up to date as of 4/6/12
2.) Under the device manager, there are two display adapters listed: AMD Radeon HD 6490M (yay!) and the Moblie Intel (R) HD Graphics (boo!). I disabled the mobile intel adapter and the computer did not switch to the AMD GPU, even though the device manager showed/reported that display adapter as being active. I confirmed this through DxDiag, and it didn't recognize any GPU even though the 6490M was still enabled. I got the same results when I uninstalled.
3.) I re-installed both display adapters. Still got the same results
4.) I opened up the Catalyst Control Center to try and find something. I saw there was a "switchable graphics" option, but this did not seem to turn on the 6490M on programs I selected as "high performance". I tested this for Skyrim, and the game did not recognize the card as being on.
5.) Going to the BIOS (a Phoenix BIOS), I tried to find a way to switch my GPU on there. Unfortunately, there isn't an option for that, and I could only find sites that want me to pay for a BIOS update.
TL;DR - I've tried drivers, un/re-installation, the BIOS, and the ATI program and nothing seems to turn the card 'on'.
Has anyone else run into similar issue? What I'm trying to do is find a way to shut off the shitty integrated graphics so I can use my mobile GPU permanently. I'll include more specs below, and thanks for any suggestions!
