x230 Awake from Standby with Lid Closed

[rimoth]

Hi,

Yesterday I closed the lid on the x230 and it went into standby and put it into a jiffybag for protection and then into my rucksack. Later in the evening I picked up the bag and immediately noticed excessive heat coming from the bag a smell of burning/hot electrics.

I quickly removed the laptop battery to let it cool down. I booted it after it had cooled down and it appeared to be OK, apart from the fact I dropped the battery on a hard floor when removing it.

It looks like that laptop resumed from standby whilst the lid was shut. I am under the impression that this is hardware controlled and not by the OS as it is not running. I am also concerned that it can happen again and possibility of damaging the laptop and more seriously fire.

It's still under warranty. Should I get it checked by Lenovo?

Thanks

I would make sure you have Wake-from-Standby by Magic Packet/Wake-on-pattern match in BIOS or in your power management settings/adapter settings. I would also double-check msconfig to make sure you don't have any background applications disrupting the sleep process.

Generally for this type of situation, I'd like to rule out software culprits before moving to hardware. My 2 cents.

Edit: Forgot if this happens again, you can use the command:

Code: Select all

powercfg –lastwake

to narrow culprits.

Interesting....

Just got home and noticed one of my machines is on with the lid closed, same issue you're having. It was put to sleep roughly 12am the morning before.

Here's my output from CMD:



For my machine, it attempted to resume from sleep (S3) and hibernate (S4), but seems to have failed in the process.

I ran:

Code: Select all

powercfg -h off

to disable hibernation. I think that should solve the issue and hope it does for you as well.

Hi Peptate,

I will check the bios settings.

My knowledge in this area is not great, but I was under the impression that S3 - suspend would not be affected by the OS. I am running linux so I cannot try the windows suggestions.

As for your case resume from S3 to go to S4 would be triggered by the battery level nearing empty. In my case the battery still had significant charge so it shouldn't have resume from standby to go into hibernation.

Thanks
