Asus G74SX suspend causes shutdown

Hi all,

I've owned a G74SX for months now, and recently a problem has developed. Sometimes when I suspend my computer, and then attempt to revive it, it appears that the computer has shut down instead of suspending. This does not happen on every suspend - it occurs perhaps 1 in 3 times. The shut down might be correlated with duration of suspend, i.e., the longer I suspend the more likely it is to have shut down.

At first I thought this was an Ubuntu issue, but I'm duel booting to windows and Ubuntu and I've since confirmed that it's happening in both OSes.

Any ideas?

Thanks much.

 

By suspend, i assume you mean what windows calls sleep and not hibernate? If that is the case, were you on battery and what was the battery level when you had to start it up again?

 

Right, sorry, I was using Ubuntu's terminology. I was in fact using sleep on windows.

The battery certainly wasn't critically low, I think it was around 50%. I'll keep an eye on it in future instances.

 

http://windows.microsoft.com/en-US/windows7/Sleep-and-hibernation-frequently-asked-questions explains Windows Sleep and Hibernate modes. The main difference is that Sleep caches your work to memory and uses a small amount of power to keep that memory alive. Hibernation saves your work to the disk and shuts down the system, using no power. Sleep and Hibernation can be adjusted in Windows Power Options.

In the Advanced Settings of your current Power Plan, you can configure the "Low Battery Level" and "Critical Battery Level" as well as the actions taken at those levels. Typically, when the Critical Battery Level is reached, the laptop goes into hibernation by default. If the laptop is in Sleep Mode when the Critical Battery Level is reached, it will be placed in hibernation and shut down to keep you from losing any work.

I suspect you initially put your laptop to sleep, but at certain times, the battery drains down and the Critical Battery Level was reached, causing the laptop to be placed in hibernation and shut down. You are seeing a resume from hibernation and believe this to be a restart of your system. Could this be what is happening?

 

Your idea seems reasonable, but I think something else is happening - it just happened again with my battery at 48%.

I primarily use Ubuntu. I'll have to do more testing in Windows. I don't think I mistook the hibernation for shut down, but it's possible.

Thanks for the advise.

 

In fact, I seem to recall that when I restarted it I had the "Windows did not shut down properly" screen. I'm going to continue investigating.

 

It may be worthwhile to check the Windows System and Application Event Logs for any Errors or Warnings. The Details of these events may point to a troubleshooting direction.

It could be possible your battery needs to be recalibrated. In other words, it shows 48% remaining, but the true power level is actually much less. See HP Battery Health Center for details on how to accomplish this.

 

I've checked the logs, and I didn't find anything useful. It recently happened on a full charge.

This is starting to seem like an RMA, especially since it happens in Ubuntu and windows.
