Model: Lenovo Legion Pro 5 16ARX8 - Type 82WM, 82WM0064PB, AMD Ryzen 7 7745HX, RTX4070, RAM 16 GB (2x 8 GB DDR5-5200), 512 GB SSD PCIe, 16'' WQXGA 240 Hz 500 nits, Win 11 Pro 64-bit 23H2
Describe the issue/When did it start producing the issue/Did you install new drivers or software?:
Yesterday, after updating drivers via Lenovo Vantage and updating the system. I also enabled Bios security.
In addition, few days ago I disabled booting from USB in BIOS and set the Administrator password on BIOS.
What have you tried already?:
The computer restarted and only a black screen appears, which dims from time to time. The diode on the power button lights up, the diodes on the Esc, Caps Lock and Num Lock keys blink simultaneously. The keyboard backlight lights up, the fans work.
I connected an external monitor - no effect.
I disconnected the power supply. I did a hard reset (60 seconds).
I disconnected the power supply battery and the BIOS battery. I held the power button again to discharge the capacitors. I connected the power supply and turned it on. Same effect - nothing.
I removed the RAM, and after installing one module, I did the above steps again step by step. The same with the second module - nothing.
I also replaced the SSD drive with another drive with a working system.
I did the above steps again - still nothing.
I used the key combination: Ctrl + Shift + Win + B - still nothing.
I tried clicking through as on the BIOS simulator for this model to restore default settings, but it didn't help.
Is there any way to start it?
I have a warranty, but if I could start it without service, I would be grateful for the help.
Can you provide images/videos to show us the issue:
