My laptop was working perfectly with windows 10, then Lenovo System Update recommended update the bios, the laptop was connected to the AC, after install the laptop tried boot but it power off automatically and this behavior was repeated over and over again. Lenovo logo wasn't showing, i can't access to the menu boot and bios menus also.
Help please, I am very disappointed.
Right now luckily
I have removed the back cover.
I disconnected the button battery
I have disconnected the battery.
I pressed the power button for 1 minute to empty the load.
I pressed holding the Fn + R keys.
I have connect AC power suply.
I have pressed the power button.
A beep has sounded (while still holding down the Fn + R keys).
I have released the power button and started normal boot.
It working now.
P.D.: I have downloaded BIOS_update.exe and extract filfe 6SCN48WW.CAP, renamed to BIOS.cap and copied to a usb stick. I have did all detailed operations with usb stick connected but I think laptop has not read it.

Your feedback helps us improve!To remove back cover is neccesary to extract dvd player and unscrew 2 more screws from its location.
Then you can disconnect battery and battery button cell
Thank you so much broh, you save my life, regards from Peru.
