Ryzen 7 2700X B450 Pro4 16 Gigs of RAM 1050Ti 1TB Crucial NVMe SSD Now I built this computer and installed Arch Linux. When I put my PC into Suspend, it turns aff and the little LED on the case starts flashing. When I resume it however, the CPU fan glows but doesn't spin. The PC does nothing and is just stuck there. Reset button or longpressing the power button dont work, I have to turn off my PSU. Help? I am on BIOS version 3.50

For suspend/resume check the following Bios items: Mandatory, i think: OC Tweaker\CPU Configuration\SMT mode: Enabled(!) Advanced\ACPI Configuration\Suspend to RAM: Enabled Further items, if available: Advanced\CPU Configuration\Cool & Quiet: Enabled Advanced\South Bridge Configuration\Deep Sleep: Enabled This is from my X370 board, maybe the positions in your bios are different. ------------- Asrock Fatal1ty X370 Professional Gaming Offline Under test: MSI X570_MEG_ACE | AMD Ryzen 9 3900X | Scythe Mugen5 | 2x16GB F4-3200C14D-32GTZ@3466 | ASUS GeForce GTX 1080 Ti FE |
