I think you can , if motherboard supports.You can check your motherboard details at Game-debate , then you can be sure for it and you will know the number of GB's you can install in your laptop.
Well i will never give my laptop for any kind of upgrade.
Last time i contacted laptop support for RAM upgrade and Motherboard service , they give me a refund for it.:'D
I think you should get to a Computer expert to get much more about it.
