just found out why you cant disable the onboard gpu in bios, its because the bios is locked by lenovo (nice of them)
it is possible to unlock it
but requires a modified bios
this link will tell you more
nVIDIA stopped producing complete GPU cores for laptops with Intel CPUs. The Optimus is only the "back half" of what a desktop Geforce GPU core contains. The Intel IGP cannot be disabled, because without a front end, the Optrimus relies on the Intel chip to do everything. If I was gifted a laptop with an Optimus, I'd swap it for another machine to avoid the nvVIDA cripple.
I thank you for trying to help me but it took me a lot of time to be able to purchase that laptop. BF4 is the only game that does not work so I do not think the laptop is at fault here. BF3 works perfectly at 900 p on high/ ultra on multiplayer. I would have tried all the other suggestions, that going to device manager and disabling integrated gpu might work. But the sad thing is I am out of game time. I however did discover a soluttion though and it worked.
For the solution to work,
I had to go in origin and run the default bf4 in 64bit version. Then oh well I would get 4-5 fps and with all that pain I would change the graphic settings to a more suitable thing for my laptop about med/high. Then i quit the game and made origin open the 32 bit version of the game and for some reason that worked. I played it for a few days like that but then it started crashing to desktop again. So i do not feel very confident buying the game just to find out it does not work. 20 dollars is a lot of money where I live.
Would it be possible somehow to get an etension on my game time? a couple of days just to check things would be good. If things work out I assure you I will purchase the game.
