IPhone 4S manually syncing problems?

In my iPhone 4S the manually sync is not working. I tick the option of manually manage my music and videos but after I connect it to another laptop the tick is not present in the other laptop or sometimes not visible in my laptop itself. Please suggest me as to what I should do to manually sync my IPHONE 4S

Go to apple.com and troubleshoot for itunes sync

Have you entered your password correctly? What iphone are you using, unlocked, jailbreaked, sim lcoked?
