Slow suspend wake-up on T420

[ess3nt1al]

About a week ago i got myself used Thinkpad T420 with ssd, 2gb of ram and Windows 7 with all drivers installed on it. I installed EndeavourOS (arch linux) on it, and every time i opened it in suspend mode, the screen turned on instantly and i could use it. Now it turns on only after 6-8 seconds. Although it is a pretty good time, it's still annoying to me and i want to fix it. I had swap turned off when it was working well, i have it off still. Upgrading to 6 gb of ram did not help. Reinstalling the system also did not help.

How is it suspending? Is it going to S2/S3 (suspend to RAM) or S4 (suspend to disk/hibernate)? S4 will take longer to resume from (esp. if you add RAM) because of the need to access the disk.

Thank you for your reply.

I checked my dmesg and journalctl and figured out, that i'm using "deep" suspend mode which refers to S3. I think it was S2 or S1 before, which are faster, so i am now researching how to change it on arch linux
