Solved! Lenovo laptop starts then shows Lenovo and then shuts down

My Lenovo laptop starts then shows Lenovo and shuts down and the same process goes on forever and I've tried the charger and battery trick too but nothing works

If it's in warranty, contact Lenovo. It is likely a bad motherboard. You can try a different hard drive and/or RAM but most likely issue is motherboard.
