Will this memory stick work with my laptop?

My laptop is a Compaq 615 with 2gb of ram
I wanna add another 4gb to get 6gb

Check with Compac, You might not be able to add more memory without replacing All the ram. Also laptops are very picky about the ram they use. Check with Compac to be sure you have compatible ram
