I tried to apply the process to my Dell 7430 and Ubuntu 22.04, and although I managed to enable deep sleep in the kernel, unfortunately my laptop never exits deep sleep (BIOS version 1.7.0)

Any comments / suggestions?

Btw, my dsdt.dsl had 3 errors which I resolved by uncommenting lines 105/106/107

//External (_SB_.PC00.LPCB.ECDV.CMFC.DLPN, UnknownObj)
//External (_SB_.PC00.LPCB.ECDV.CMFC.IDMN, UnknownObj)
//External (_SB_.PC00.LPCB.ECDV.CMFC.IDPC, UnknownObj)
Enter fullscreen mode Exit fullscreen mode

s2idle is unsafe for me for carrying the laptop since it overheats

Many thanks

I don't know so much about DSDT tables, the 7405 workarounds were really simple. I'd suggest using a cutting edge distro like openSUSE Tumbleweed and see if newer kernels provide better s2idle support.
