As I mentioned, another distribution, i.e., Void Linux is installed on the same compuber. When I boot from Void, I have no problem with Suspend. |

So it must be a configuration problem. One thing you could try is copy the kernel config from Void and see if ti works.

I have no idea how this works, but this really works: I just tested the command found in Google
| Code: | | echo freeze | sudo tee /sys/power/state |
after resuming from suspend, everything runs smoothly as before suspend.
Thanks to all who help me, your help encouraged me to solve the issue. I will write a script to run this command more easy. |

| Now I realize why suspend works in Void, not in Gentoo (before installing Gentoo I installed Arch, there suspend did not work either), this is because in Void it uses the command zzz which is also a kind of script for the effect of suspending the system. So the normal suspend does not work at all on my computer, probably because of a kind of special setting in BIOS of the HP computer, which I cannot change. I learned a lot from the article: https://www.kernel.org/doc/Documentation/power/states.txt. |

| What does the script zzz do? It should be possible to replicate those steps on Gentoo. |

I am not an expert of Void. On the man page (https://man.voidlinux.org/zzz.8) it says:
| Code: | zzz is a simple script to suspend or hibernate your computer. It supports hooks before and after suspending.
-n
dry-run mode. Instead of performing an ACPI action, zzz will just sleep for a few seconds.
-S
Enter low-power idle mode (ACPI S1, kernel name "freeze").
-z
Enter suspend to RAM mode (ACPI S3, kernel name "mem"). This is the default for zzz.
-Z
Enter hibernate to disk mode (ACPI S4, kernel name "disk") and power off. This is the default for ZZZ.
-R
Enter hibernate to disk mode and reboot. This can be used to switch operating systems.
-H
Enter hibernate to disk mode and suspend. This is also know as suspend-hybrid.
FILES
Before suspending, zzz runs the executable files in /etc/zzz.d/suspend in alphanumeric order. After suspending, zzz runs the executable files in /etc/zzz.d/resume in alphanumeric order (not in reverse order!).
The environment variable ZZZ_MODE can be used in these hooks to differentiate between standby, suspend, and resume. |
It can be installed on Arch and some other distros. It requires a linux system with /sys/power/state and optionally /sys/power/disk, cf. https://github.com/jirutka/zzz. I hope, one day it will also be available on Gentoo system. |
