[SOLVED] Laptop startup automatically?!

Something really weird happens... my Toshiba R835 boots up automatically after poweroff.
It does that 5--10 mins after being shutdown.

I didn't touch the BIOS at all... the only thing that I guess might be related is that I upgraded to Linux kernel 3.1.5-1-Arch

Help, please! I don't want to disconnected the battery after time I turn off my machine.

Re: [SOLVED] Laptop startup automatically?!

Also, now I've just found out after removing all the power source (AC and Battery) the laptop starts right away when the AC is reconnect

I hope I'm not the only one having this problem...

Can someone tell me how to downgrade the kernel back to 3.1.4??

Thanks in advance

Re: [SOLVED] Laptop startup automatically?!

I'm not having this issue and have absolutely no idea why it is acting like that. Regarding downgrading packages => https://wiki.archlinux.org/index.php/Do … g_Packages

The wiki is your friend -_-

EDIT: If you haven't cleared your pacman's cache then you can install your old kernel using the '-U' switch.

Re: [SOLVED] Laptop startup automatically?!

Thanks for the reply. Now that I think about it, it couldn't possibly be a software issue, could it? After the machine is shutdown, there is no software running...
Also, laptop is not hooked up on LAN, so it can't be waken up by that either.

For a moment, I thought it maybe a change in voltage that triggers the booting... however, it does that even just on battery (with no AC connection). That's a real mystery.

If anyone experience that, please post it here so that I know.

Did you touch your bios at all? Mine has a setting for rebooting or staying off when the power gets restored, in case no one is around to turn it on.

Re: [SOLVED] Laptop startup automatically?!

Same problem on my Toshiba Satellite R830. It is due to the latest kernel upgrade: http://permalink.gmane.org/gmane.linux.kernel/1227895

As a workaround, I have put these two lines in my /etc/rc.local to set the alarm time 1 year ahead:
sudo sh -c "echo 0 > /sys/class/rtc/rtc0/wakealarm"
sudo sh -c "echo `date '+%s' -d '+ 1 year'` > /sys/class/rtc/rtc0/wakealarm"

Re: [SOLVED] Laptop startup automatically?!

Sorry, "sudo sh -c" is obviously not needed in /etc/rc.local:
echo 0 > /sys/class/rtc/rtc0/wakealarm
echo `date '+%s' -d '+ 1 year'` > /sys/class/rtc/rtc0/wakealarm

Re: [SOLVED] Laptop startup automatically?!

Thanks everyone for the replies and robegrassi's fix works for me. So I will go ahead and mark this as [SOLVED]
Looks like the issue has been reported upstream, hope that will be fix in the next kernel release.
