Hi,My name is ***** ***** certified computer professional with over 10 years experience. I will be glad to assist you with this. .I am sorry to hear that you are having this issue.
The power reset by removing the battery will get it powered on if it is a glitch with the software or operating system. Unfortunately this sounds like a hardware failure. Try holding the power button for 60 seconds with the battery removed and the power adapter connected. Let me know if any lights come on the front or keyboard please.
I am sorry for the delay getting back to you. I was on a call and had to be away from my computer. If you cant hear the hard drive spinning and trying to initialize then it is going to be a bad motherboard. If the hard drive comes on briefly and then stops it will be a bad hard drive.
what is the serial number on your Lenovo?
