Laptop trouble sleeping properly (battery drain) - fresh install lacks hibernate?

[currentshaft]

well , thanks, might look into this.

have updated now to latest bios 1.37 from lenovo, will see if it helps.


however, automatic installer has mad no swap-file available, so i wonder how i can enable hibernation?

the idea being, that the lptop after some time in suspend, say 2 hourse, does hibernate, which seems reasonable to me; also , the modern battery sometimes does not hold a charge that good / eg. depletes itself after fewer charging cycles.

remember that on older powerbook, even after long time in "suspend" it still would turn on and let do basic tasks.

rich@rich-ThinkPad-E590:~$ sudo blkid | grep swap
(no result)

I wouldn't worry about the swap yet. Run the Intel script I linked to debug your sleep state first.

thank you, that was helpful.

sudo ./s0ix-selftest-tool.sh -s

---Check S2idle path S0ix Residency---:

The system OS Kernel version is:
Linux rich-ThinkPad-E590 6.5.0-44-generic #44~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue Jun 18 14:36:16 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

---Check whether your system supports S0ix or not---:

Low Power S0 Idle is:0
Your system does not support low power S0 idle capability.     
Isolation suggestion:     
Please check BIOS low power S0 idle capability setting.

might have to ask @Lenovo if they can enable this function in BIOS update?
the laptop has i7-8565u cpu that should be able to save power efficiently?

Hibernate is disabled on (y)Ubuntu and needs to be actively enabled, which is not easy. There might be a little program to do this, I haven't checked.

Here's the recipe;

PS: I've never gotten it to work with a swapfile, you definitely need a swap partition.

i remember using debian and the installer would automatically present me with a swap partition when doing automatical install, around 1.5 size of ram;
Ubuntu has improved on installation routine somehow, but this seems a bit cleearly a regression if automatic install on a dedicated HDD/SSD does not give enough space for swappartition/hibernation.

EDIT: have checked and there is definitely no swap space; am i to blame that i did not "manually" partition the drive? would think not, this should be offered a standard, if the feature is useful (as it clearly seems).

I can't comment on installing Ubuntu, as I run Lubuntu which uses a different installer.

But yes, I always choose manual partitioning, as I like to keep / and /home separate. This also includes defining a swap partition.

lost around 28% of battery just in 1 day and some hours, which seems definitely excessive to me.

Why not just turn it off for anything longer than an hour?

the idea is to pick where left , and therefore use hibernate;


how i tried this approach here

https://www.wikihow.com/Attach-a-Swa...ition-to-Linux


and it seems to function halfway;

with

"sudo pm-hibernate" or "sudo systemctl hibernate" it effectively would "hibernate" , but instead of picking up where it left, it would not save the RAM state, instead just shutting down the machine; and upon clicking the power button, it would normally restart;

is this the wrong method to attach the swap to Ubuntu?

Ubuntu has made it much harder to hibernate from 22.04 thru 24.10
check with:

sudo dmesg|grep hibernation

I i would have only Ubuntu installed, it would be easy to miss those firmware updates, or how could i achieve them?
thanks

I use topgrade for all, Topgrade: A single utility to take care of all kinds of updates: https://itsfoss.com/topgrade/
I've used that for a little over 2 yrs now, and not one mishap in that time. (This is needed "fwupd ")

Thank you very much!

This enabled the Hibernate after i manipulated the SSD by inserting a Swap partition via a Gparted Livesystem.

Still investigating the Battery drain , though

("sudo pm-suspend" is much more effective than just closing the lid on the laptop | > wrong assertion, it is not so much more effective, sucks battery just as closing lid

Dunno why you're mentioning "pm-suspend". It should be "pm-hibernate" if you're using pm-utils.

The basic command is:

sudo systemctl hibernate

Complete laptop status will be be stored to disk and the computer will turn off. No battery drain at all.
