Computer/laptop turns on by itself

diver92 · 2011-04-19 15:15:46

Hello!

After upgrading to kernel version 2.6.38, my laptop become to turn on by itself.
It happens all the time. After turning of laptop by command "poweroff" or "halt -f" laptop switches off, but sometimes, it turn on by itself.

I tried to downgrade kernel. Spontaneous launches stopped.
Again set a new kernel version - began to run again himself.

How can this be?

Just want to note at a time when the laptop is running himself, he is not connected to the LAN or to an electrical source.

The same problem I have seen on a desktop computer.

Sorry for my English.

Regards, Vlad.

i fear that your computer has developed a mind of its own. kill it now before it kills you!

I have this issue also. It happened twice; once immediately after shutting down, and the second time a couple of minutes after turning the PC off. I wonder if it's software or hardware related. It happened only on the new kernel. It's not annoying, as it is rather unfrequent.

try

# shutdown -hP now

Interesting, on my new Thinkpad x220i (which I set up just this weekend), the same happens, but with a slightly different pattern (more regularity):

If on battery, it turns on automatically each time after it has just shutdown (whether I use "sudo shutdown -h now" or "sudo halt" doesn’t make a difference).

If on AC, it doesn’t turn on after shutdown when using "sudo shutdown -h now" (have not tried yet with "sudo halt").

I disabled WOL in the BIOS as well as bluetooth, which I found in some forums to be responsible for this behaviour.

I’m so hoping to fix this problem with "shutdown -hP now"…

edit: I tried now and it turned back on after 2 secs, the same as with shutdown -h now or halt. What could this be? I have not consciously installed any wol software nor even fiddled around with hibernating/suspend scripts.

I’m using Stock Kernel with laptop-mode-tools… which information are needed in order to hopefully fix this soon?

Best,

Jakob

It sounds very much like the bug described in this thread https://bbs.archlinux.org/viewtopic.php?id=113985

jakob · 2011-05-10 18:46:36

Haha how could that be? Just tried to use the conservative instead of the ondemand governor, and I can now reproduce the bug with not shutting down linux. But if I go back to ondemand I have this bug all the same as well… seems as if I’d have to wait simply for a fix of it.

I have the same behavior in my laptop. Does anyone have some news about this issue?

Which laptop (and more importantly) which kernel version? Most of the time, I use hibernation by now, but I think I am quite sure that I didn’t encounter this wrong behaviour anymore (did a BIOS update for my thinkpad but I think it was someweher in linux 3.0.3 or 3.0.4 that switching off the computer started to work again.

mikesol · 2011-10-25 11:42:01

My laptop is a Sony VPCEB4C5E and have the kernel 3.0.6.

I'm also use hibernation as a quick solution, but I think that this is not the best.

Regards.

I had this behavior since 2.6.38 (turning on by itself after shutting down, even without battery), but got recently fixed with the recent laptop mode tools update released a few days ago. This is on a HP Pavilion 2415nr.

Hey everyone, I've been experiencing the same thing. I remember dealing with a very similar issue maybe 3/4 years ago on Debian, which was solved by a kernel update... We'll just have to wait for an update then I guess? Oh, by the way, this is NOT a laptop, so it's not solely a laptop-thing.

I have this issue with my new Thinkpad L430.

Anyone found a solution?

When I turn it off it goes a few secounds and it turns itself back on again. This started to happen after the latest upgrade.

It does this a few times until I get it to stay off.

what command do you use to shut it down? systemctl poweroff works fine on a systemd box…

thoho180192 · 2012-10-17 14:36:17

I use systemd, but i shut down via gnome3
So that depends on what command gnome3 uses. I'll google it now and see if I can find that out.

thoho180192 · 2012-10-17 14:38:51

It seems like it is some kind of gnome command.

gnome-session-quit --power-off
Dont know what command that this command calls to actually shut off though.

Edit: stystemctl poweroff does the same as gnome 3

thoho180192, please do not necrobump threads.

This thread in 2011 is no longer relevant because we didnt have systemd then. Start a new thread and explain what your problem is in detail.

Closing...
