Ubuntu – Ubuntu wakes up after few seconds of sleep

14.04suspend

I'm having a serious issue that makes my computer to wake up automatically without any keyboard or mouse click, it stays in sleep mode about 8 seconds.

Edit: It happens randomly, sometimes it just doesn't wake up and works properly, I can't find a constant way of reproducing it.

Is this possible to fix it? If not then how can i make my laptop to hibernate when i close the cover?

I'm using hp pavilion dv6 notebook with additional broadcom wireless and nvidia drivers if it helps.

Edit:

Here are some info about my /proc/acpi/wakeup;

I'm afraid I don't even have a PBTN entry so I don't want to mess up my system making wild guesses and disabling things I don't know -what if one of them refers to my power button?

Here is some relevant info from my var/log/syslog;

I had a very similar problem; I will show you an example but you will need to adapt it to your computer. The output here is from my desktop (and trimmed down), so apply cum grano salis.

Check the wakeup events for your PC: 

2& [romano:~/etc] % cat /proc/acpi/wakeup 
Device  S-state   Status   Sysfs node
PCI0      S4    *disabled  no-bus:pci0000:00
COM1      S4    *disabled  pnp:00:06
PEGH      S4    *disabled
PEGL      S4    *disabled
IGBE      S4    *enabled   pci:0000:00:19.0
PCX1      S4    *disabled  pci:0000:00:1c.0
PCX5      S4    *disabled  pci:0000:00:1c.4
PCX7      S4    *disabled  pci:0000:00:1c.6
HUB       S4    *disabled  pci:0000:00:1e.0
EUS1      S3    *enabled   pci:0000:00:1d.0
EUS2      S3    *enabled   pci:0000:00:1a.0
PBTN      S4    *enabled

The enabled events are the one that can wake up your computer. One of these is firing up in your case; you have to discover which one.

You can toggle the wakeup status on, for example, EUS1 (whatever it means --- no idea) with the command: 

echo EUS1 | sudo tee /proc/acpi/wakeup

and then you can check that the wakeup is disabled, by repeating the first command. Now you can try to suspend and see if the PC stays suspended or not. Repeat.

Do not disable the event on PBTN --- it is the power button. You can be unable to resume in that case!

My strategy is normally to disable everything minus the PBTN --- now the resume should be trigger only with the power button. You can then try to reenable other sources (or not).

Once you have found the culprit(s) event(s), you can add them to your /etc/rc.local to make the change permanent. Notice however that the interface is really badly thought, and you can only toggle the status of enabled/disabled, not set it; so for example to disable the EUS1 independently on its status you should use 

grep 'EUS1.*enabled' < /proc/acpi/wakeup >/dev/null && echo "EUS1" > /proc/acpi/wakeup

in your /etc/rc.local.

In my case the culprit where EHC y XHC devices, probably because I have an USB keyboard (not sure though), this is en excerpt of my rc.local:

for device in XHC EHC1 EHC2; do
    grep $device /proc/acpi/wakeup | grep enabled > /dev/null && {
        echo Disabling wakeup on $device 
        echo $device > /proc/acpi/wakeup
    }
done
