first of all, my name is Michael and this is my first post in this board.
I got a problem with my Lenovo ThinkPad S540.
If I switch it on the system fan will start and the keyboard backlight glows but after a few seconds all stops and it start again.
It repeats many times until it start suddenly and windows 10 comes up.
The problem exists since 4 or 5 months.
I hope you have an advice for me.
