I have a Lenovo Legion series, the last couple days, when i power down or restart, it shuts down, but the fans stay on and it has a white power button on.
When I press power it does nothing, when I hold it, after 10 seconds it turns off the light and fans. Pressing or holding again just turns the light on and no fans.
It will randomly turn on properly after a while of messing about, notably, once it turned on after i lifted it and put it back down, and it powered on once into bios after i tried to update them and it didnt restart automatically or when doing manually for 20mins, then randomly went to bios, and went back to just the white light and fans.
Idk if its anything aswell, but my laptops keyboard backlights dont come on, only when it finnaly boots properly they do, and my usb keyboard turns on and off with the white light.
Also my monitor turns on everytime the white light does and says no signal, so its doing something to the monitor.
Ive tried holding the power for 60 seconds, doing the power drain thing, nothing works. Just random when it wants to work.
It has also booted when left on the white light with no fans after abiut 10mins untouched.
