That's a confusing statement. It turns on and stays on fine but when you restart it, it just shuts off. I would recommend turning it on the way that it stays on. Could be lots of problems. You might need a new battery. I had a laptop before where the contact points went bad where you plug the power adapter in and I had to solder it. Try running a malware check too. Do it from safe mode.
