Lenovo Thinkpad T460 power light blinking too much

2020-02-13, 13:20 PM

Why it is happening?? What is wrong?

 

1.When my laptop T460 is turned off, the power light is blinking three times in every ~3 minutes. I made a video. Starts blinking in a video on ~57 second.

2. When I press shutdown, laptop is going to turn off and it shuts down after power light blinking ~28 times. I made a video.

1. I saw this  once with my T460p a few months ago.  I think I've solved this by disconnecting the system  from AC power and battery for a few minutes. The T460 may have also an internal battery,  you'll need to deactivate it in BIOS too.

Just in case, do a full shutdown, no hybernate and no shutdown with fast startup!

 

2. this looks like the usual flashing sequence when system is entering  hybernate mode.  Disable fast startup!
