Laptop stuck black screen when it starts and power, caps lock and F2 (air plane) lights on. When I hold down the power button, the CPU fan starts spinning at high speed. If AC adapter plugs in it restarts and again lights on and black screen again. I connected the laptop to the monitor with the hdmi cable but nothing changed. RAM is soldering on the motherboard that's why it can't be disassembled. In my research on the internet, everyone says take out the bios battery and plug it in. But I couldn't find the bios battery and cmos chip on the motherboard.
I look forward to your help in solving the problem.
