vpcz11 turns on being in bag

Since I remember my vaio there was always a problem with random power on.

First it was caused by my Anywhere MX mouse when I forgot to close it and it woke up laptop in my bag.

But now I see that even though I close my mouse, vaio turns on itself sometimes being in the bag.

This worries mt cause several times I took it out with screen liquid crystals melted to black color. Took it a while to cool down and turn back to usable.

The wired thing is that in this condition it does not even itself down due to overheat. I believe it goes 100-120 C

My settings are to "Sleep" when I close my laptop.

Anyone know what's happening? Is this some kind of settings needed to switch in bios to prevent it waking up?

 

Shut down your laptop, don't sleep it.

If you sleep it turn off all devices "this device can wake up computer" in device manager.

 

In addition (if you want to leave it in sleep mode in your bag), make sure that "Allow wake timers" are off for all power settings (it's in the advanced power settings->Sleep).

 

You clearly shouldn't put your Z asleep in a bag, even if you turn every wake timers or devices off the flex of the screen can awake the laptop from its own keyboard if it handle a sufficient pressure...

 

I sleep my P in a bag, but I would never consider sleeping the Z in a bag.

 

good thread - I did encounter that before

 

Check for any 'wake on LAN' options in the BIOS. If you don't mind the hassle, turning the Wifi switch to the OFF position before closing the lid should also help.

 

Thought i had Deja vu...

Yep. Same happened to me. Look for my thread from last year. My screen was all kinds of crazy colors when I opened it up.

 

mine is nearly ruined

sony does not do a good job in this aspect

 

I don't know if this helps any...
but on my old HP TM2, it would randomly wake up while in the bag and randomly restart at the slightest movement. I found one of the memory sticks was slightly loose and after properly connecting it, the problems went away. Or maybe it was just a coincidence... but doesn't hurt to take a minute to double check your memory sticks anyway

 

I don't know why people just put it to sleep and place in their bags... reminds me of the Mac folks...

 

I haven't had an issue in months. I don't think mine was waking up in the bag, it just never went to sleep to begin with. I just assumed that if I closed the lid, that it would go to sleep. Wrong. Now I wait for the LED to go orange before zipping up. Every once it in a while, it doesn't sleep when the lid is closed.

 

That's a setting you can turn on and off in Vaio Control center under Power Management >> Lid Action Settings. I like to sometimes just leave my Vaio on with the lid closed to i set it to do nothing when lid is closed. In any case, I find the Z shuts down faster than if you put it to sleep... then again i guess you can just pick up where you left off so... there is a trade-off i guess.

 

Well, I do prefer Sleep over Hibernate since since it does not write 8 gig to my SSD multiple times a day. Full Shutdown is not an option for me. I have many apps running for weeks. If I go home I leave all my work apps running to continue next day. Quite convenient for me.
This is definitely Sony issue since when Lid is closed no kind of pressure on keyboard nor devices should wake it up by default.

The worst part is that it does not shutdown on critical temperature!
Is this somehow configurable to force it? I just want to avoid thermal damage next day.

 

Well, I've tried to wake up my laptop by pressing on the lid as hard as I dare (don't want to break it!) without being able to press any of the keys. So I don't think that's it. My best guess would be the WiFi/Bluetooth. When the laptop encounters a change in the WiFi environment, e.g. a different access point comes in range, the laptop might wake up to evaluate this new possible connection.

 

This is partly a fault with Windows 7.

 

Agreed. IMHO ALL automatic wake-up events should be disabled by default. Users who need this functionality should be told how to enable it.

 

But, sony is partly responsible...they could have configured BIOS/EFI to not allow the machine to wake from sleep when the lid is closed (much like how you cannot use the power button while the lid is closed). But people would whine about it because for some users being able to wake while the lid is closed is needed (IE as an htpc, or with network shares that need to be accessed).

Also, one of two things is happening with the thermal protection, remember we do know the protection works when gaming, etc.

1.) The CPU/GPU isn't overheating, or is only overheating enough to cause throttling - but the rest of the system cannot handle ~100C temps. In this situation Sony should've implemented a temperature sensor elsewhere in the unit to cause it to shut down at a specific temp (ie 70c)

2.) The CPU/GPU are overheating and for some reason since the lid is closed the shutdown process fails. This would be fixed with better EFI code, I'd imagine.

Either way, it's bad form to place a laptop that's asleep into a bag. I mentioned once before I had a fujitsu P literally melt itself from doing this.

Hibernate isn't going to kill anyone.

 

so you mean: you do not see how a notebook could wake up "by itself" out of the hibernation status?

because this is exactly what i believe is happening to my new SB....unless i am really making some other kind of mistake.

i am convinced it woke up from hibernation several times...wake timers cannot wake up from hibernation? any idea what could cause a notebook to wake up from hibernation at all?

 

^Good point, depending on the machine, I do believe WOL and wake timers can still wake a machine up from hibernation depending on how you have it configured. Just disable all of that.

 

I suppose eventually they'll get around to having these options disabled by default, like they have done for file and printer sharing on public networks.

 

this is a knowm problem
