My teen wakes up early to play video games

My son is 13 years old and keeps a laptop in his room to do homework each night. After setting some ground rules about computer time, I thought everything was going well. He was spending more time outside of his room talking to his brother, building with his Lego sets, and getting some outdoor time. Soon, however, I discovered that he was waking up at 4:00 am to play video games before getting ready for school. I could remove his laptop from his room every night, but here is what worries me. He was willing to lose sleep to sneak in time on his computer. Taking his computer out of his room before bedtime may be a good short-term solution, but what can I do to teach him that sleep is more important than screen time?
