Hello!
I have a Lebovo B50-70 laptop. Until yesterday it was working fine.
In general, I do not turn it off, I just close the lid. Yesterday there was a need for a reboot.
It doesn't turn on now. The power button is on, the cooler is working, some kind of click is heard once.
I pulled out the battery, pulled out the RAM bar, wiped it with an eraser. Turned it on at night and went to sleep. I woke up at 3 am, it booted up. But I have two OSes and Ubuntu is loaded by default. I need Windows. Rebooted again and went to sleep. Still a black screen in the morning.
I don't think the display is the problem.
I will be grateful for advice.

Turn off the power by hardware by holding your finger on the power button for more than 3 seconds.
Turn it on and time it.
Try booting from a live cd and checking your hard drive.

Well, as an option, check the hard.

On lenov there is a restore button, if you press it what happens? Try entering the BIOS (DEL or F2, I don't remember). Try booting into safe mode (F8).

The problem is in the crooked BIOS on the Lenovo B series, more precisely, not in the crooked, but rather more sharpened for Windows than for Linux.
Once I installed win + arch, the bios stopped opening (when only Windows was there, this was not the case, and the laptop did not react to any buttons while the lenovo logo was displayed), the hornbeam immediately opened and only the operating system loaded, partially restored the bios to work resetting it by removing the bios settings battery (but this is temporary, usually before the first reboot)
But then updating the bios from the offsite lenovo helped me (but again, it did not immediately set exactly (notebook speakers fell off), and only from the 2nd or 3rd time everything was fine.

In general, I think that the problem is in the BIOS, bring it to the service, or as I use a proprietary utility.
