Standby prevents GRUB from loading

Asked by Steve Starcevich

I seem to be having a problem where if I go into standby during an Ubuntu session, and then I reboot/shutdown my laptop, GRUB does not load when the computer is turned back on, no matter how many times I try turning it off and on again.

A temporary fix I've found is to boot into GParted Live off of my flash drive, and then restarting it again; however, I don't actually have to do anything in GParted to get GRUB working again, I just restart and it boots like normal.

For more information I have a forum post already here: http://ubuntuforums.org/showthread.php?t=1652035

To update this problem with new information I've found:

1) After letting the computer sit at the flashing "_" on startup where the GRUB menu would normally be, I get a message after a few minutes telling me to insert a bootable device. So it confirms that GRUB never even gets a chance to load.

2) As if this problem isn't strange enough, I've discovered that letting the laptop remain shutdown for a few minutes also allows me to get my GRUB menu back. This discovery comes with another oddity, letting it sit shutdown ONLY works if the laptop is running off of the battery this fix does not work if the laptop is plugged in.

3) None of this happens under Windows 7, so it's not simply some odd bug with the laptop (which is an ASUS K72DR by the way).

Does anyone have any possible explanation for any of this?

Does your swap area is bigger than RAM ?
Have a look at links:
   https://help.ubuntu.com/community/SwapFaq
Does the computer power off by itself or have you to press power button ?

1) I have 3960MB of RAM & 5858MB of swap showing from "free -m"

2) When it doesn't boot properly I have to turn it off by the power button manually. It does not shutdown by itself, but also I don't have to hold the power button down for 6 seconds or anything, it shuts down as it does when its not frozen.

Hi :)

Is this still a problem?

Generally i would recommend avoiding using hibernate or sleep modes because they leave the machine in a highly vulnerable state more liable to problems from physical knocks and bumps. Ubuntu should shutdown really fast nowadays whereas going into sleep or hibernate modes takes a lot longer than it looks. Fro better battery-life it is also a good idea to shutdown properly.

Please let us know how this is going!
Good luck and regards from
Tom :)
