Acer Swift 3 SF314-41-R2BK Black screen appears

JaqenFlaas

Windows 11, AMD Ryzen 3
During use, a black screen appears, but the keyboard backlight and cooler work.

I held down the power key for 30 seconds, pressed the battery reset button on the back cover with a paper clip, and pressed the F2 and Delete keys during startup (to enter the BIOS, there was no reaction, by the way).

Tell me what else I can try.
Thank you!

If you cannot boot to BIOS you have to open your laptop and reset CMOS, check the DDR4 module seating and do a Power drain procedure with the keyboard Power Button:
Open the back of the laptop and disconnect the battery cable from the motherboard. Locate the CMOS module (with 2 twisted wires Red and Black) and remove the coin battery. Shorten the +/- contacts inside the CMOS capsule for 2 seconds and put the coin battery back with the + sign facing up, close the CMOS capsule. Next, open the DDR4 RAM bracket, remove the module and push the module firmly back in the RAM socket, secure the bracket again, press the Power Button on the keyboard for 10-15 seconds after that reconnect the battery cable to the motherboard. Close the laptop, plug-in the adapter and try to boot.
