I have a Legion 5 Pro-16ACH6H with AMD CPU. It did not start. I updated the BIOS with the file “Legion 5 Pro-16ACH6H, Legion 5-15ACH6H, Lenovo Legion 5 17ACH6H, Legion 7-16ACHg6 AMD gkcn40ww.bin”. The device then started up again. I can also access the BIOS. Unfortunately, it always shuts down after a while. Nothing gets hot or anything like that. The strange thing is that when I have a RAM bar in the JDDRH1 slot, the device doesn't turn on. Does anyone have any idea what the problem could be?
