How to make my laptop less laggy to play games like skyrim?

I got a lenovo G50-30 with an intel HD graphics driver and 4gb ram. But the game is still far too laggy, iS there a way i can download a different driver or use more ram, as it says i'm only using 2.59 gb of the 3.89 usable. Even though skyrim requires 2gb its still playable but far too laggy to not get annoyed by it. I'm planning to upgrade the ram to 8gb when i can but for the time being how can i make the laptop faster for playing games and music production etc.

Laptops aren't for gaming. You need to build a gaming PC. They aren't really ideal for music production either. If you want to take those two things seriously, then upgrade to a PC.

If you don't want to, then I suggest downloading GameBooster and some sort of GPU overclocking software, plus a cooling pad for your laptop.

It is most likely your Video Graphics being inferior for games, it is fine for business and schools.
Your RAM is fine as it is, do not waste money on it.
