Could you please give an advice how to configure a suspend mode.
I have a Lenovo ThinkPad T14s Gen 4 (21F9S0T900). AMD Ryzen 7 PRO 7840U. 32 GB LPDDR5x 6400 MHz. SSD SKHynix 1TB PCIe 4.0
I installed dualboot: Kubuntu 22.04.4 and Windows 11. Under linux when I closed a laptop (so it shoud go to suspend mode) I got a problem, that it didn't want to wake up. I switched it off with long press on power button. Then switched it on, all lamps worked and fan worked, but the display was black. I tried rebooting several times, but only one thing that helped was 1 minute pressing the power button.
I heard that I have to choose "sleep state" to "Linux" in UEFI(BIOS) in power configs, but I didn't find such option there. After installing linux I updated all that kubuntu listed. (There were also some firmware updates). Here is what dmidecode tells about my BIOS:
# dmidecode 3.3 Getting SMBIOS data from sysfs. SMBIOS 3.3.0 present. Table at 0x212B8000.

Thanks in advance!
