Hello maruhana and welcome to community,


This is hardware issue and suspected part is system board.

Try removing the battery and trying to start the system on AC only.


If it will start up, then suspect battery fault.  If it won't start on AC, check voltage of AC adapter - should be 20 volt output


See this article for how to test with a meter, or if you have access to another adapter (Thinkpad) you can test by swapping them.

Re: Orange light blinking and buzzing noise

If it is buzzing without a battery do not plug it in again. Buzzing is bad. If it buzzes without a battery, there is a short in the power supply or the motherboard.

I do not respond to requests for private, one-on-one help. Your questions should be posted in the appropriate forum where they may help others as well.

I am not an employee or agent of Lenovo.
