Why doesn't the Z have thermal shutdown!?!?!?!?!?!?!

It happened again today. I closed my lid to put my Z to sleep and then put it in the sleeve. The first time 2 times I found it turned back on in the sleeve was only after a few minutes so it was only slightly warm. I just assumed I blew it and stuck it in without it suspended. Since then I make sure to wait for the led to go orange. Well today, I lifted up my laptop bag out off the trunk and it's insanely warm. At first I thought it was just the exhaust heating up the trunk from driving. Nope. I take out the sleeve and it's like an oven. I open up the sleeve and the Z's light is green. The machine is like a hot brick. I open it up and the screen is discolored in parts. Great. I let it set with the fan going full blast for 15 minutes and everything cools down a bit and the screen is back to normal. Even right now, the palmrest is on the warm side. The battery was fully charged when I put it in the sleeve, it was at 16% when I took it out. So it ran for about 4 hours in the sleeve.

Why does it wake up when the lid is closed?!?!?!?!?

Why doesn't it go back to sleep especially with the lid closed?!?!?!?

THE BIG QUESTION IS WHY DOESN'T IT HAVE THERMAL SHUTDOWN LIKE MOST LAPTOPS!!!!!!!!!!

No more sleeping like a normal laptop. I'm hibernating every single time now.

 

Take the battery out like I do

It does seem to have thermal shutdown: when I overclock the GPU a lot, it shuts down while I'm shooting at stuff.

 

when putting on my messenger bag I always shutdown

 

I can't do that. My Z goes in and out of the sleeve and bag a few times a day. I need the state to be maintained. I can't start from a fresh reboot everytime.

I just tried to hibernate. No go. It triggers the blackscreen problem for me. I have to shutdown and power with it on "speed" for the screen to come back.

I'm seriously considering switching to a X201. The Thinkpads don't have these problems.

 

Have you tried turning off USB select suspend what about wake timers? Also, it might be turning on because your screen flexes and presses a key. In any case, you should turn it off. Also about the blackscreen problem on hibernate, are you using an unofficial graphics driver? If yes, try using the officials drivers.

 

So what's turning it back on? Does it ever do that while in sleep on your desk?

 

really!!!!!!!!!!!!

this again?

maybe you should go to a thinkpad than. a Z is not for you. your doing something that pushes the lid onto a key that activates it. but you wont listen to anyone.

you can lead a horse to water but yet again can't make it drink

 

My Z starts in 28-30 secs, whhat's soo important that you can not wait in 30 secs for the system to startup.

 

maybe it has less to do with boot time than retaining the state of his workspace (running applications, windows etc). no problem with hibernation here, and I'm definitely not using the official drivers.

 

My CW did the same thing. It seems that the Sony utilities have it set up to wake up after so many minutes in Sleep and go to hibernate. I think mine was set at 20 minutes. It's stupid I know. But the thing that I found out, was that sometimes when it was woken up, it didn't go back to sleep or hibernate. It just sat there "on". It really, really bothered me, so I disabled that in the power settings in the control panel. I set it to wake up and go into hibernation after 9000 minutes..lol. NOW... if you run the Sony Utilities any, it will reset your settings, so I haven't touched any of the Sony utilities.

 

Exactly. That's what I said. If all you do is browse the web, then it's not an issue. But if you do something like development, rebooting multiple times a day is a show stopper.

 

Go into Advanced Power Settings in Windows 7 and disable Hybrid Sleep. Causes nothing but problems.

 

Already off. Allow wake timers was on though, that's off now.

 

Because you're using Windows 7.

You're blaming the hardware, but you should be blaming the software.

 

Fix your hibernation problem, that's the way to go. And yes, the z does have thermal shutdown but apparently the CPU isn't getting hot enough to trigger it.

 

Great. I updated everything and ran the Sony troubleshooter which did some stuff as well. I just wanted to fix my hibernation problem. The result. Now my graphics mode switch doesn't work.

 

I'm sure you made a "System restore" and probably a backup before you made such major change. Just revert back.

Was "it" like this from the beginning? Or when did it start happening? I'm in a similar situation like yourself - computer goes in and out of the bad (BookBook *bragging*) all the time - so I fully understand your concern.

 

My hibernate would still not work if I did a system restore. So I'm making a easy transfer file and I'm going to do a clean install from the recovery disks.

It's been this way from the start. The first two times, it was only a few mins before I pulled it out of the bag. This time was just much longer. I think it's just when it gets bumped, the keyboard smacks into the screen waking it up.

 

I finished restoring from the recovery disks and I figured out why it wasn't hibernating. I encrypted my drive with TrueCrypt. I go to install the latest version and look at the release notes. What's the big change for the latest version? Fix the bug preventing Windows 7 from hibernating. Figures. All this for nothing.

 

So I make the occasional full disk backup using Acronis True Image. The builtin Windows 7 one always says I don't have enough disk space left to run backup. Anyways, I tried to restore my drive using my Acronis backups and it says that the backup file is not an Acronis file. What? I google and it turns out this is not an uncommon problem. Another lesson learned from this debacle. Don't use Acronis True Image.

 

Use ghost like we've been telling you.

 

The Z isn't the only model to have this issue, my SZ has suffered it a few times in the past and I can assure you that nothing hit a key and that it is a software issue.

The thermal shutdown just turns down the processor speed to keep the cpu from melting, beyond that, who knows. The hybrid sleep sounds plausible though as it does wake up and then fails to enter a new state, essentially locking up the system.

Be glad the thermal system did as well as it did, an older system would have burned up. Mine ran for 4hours+ in a small bag and another time on a bed, both times the exhaust port was completely blocked.

 

Actually if I remember right thermal shutdown is built into the Intel chips. So it might be a matter of Sony not having it set right in the BIOS.

*googles it* Yes the C2D chips DO have a thermal diode so they know when to force a shut down, but the BIOS have to listen to that command.

 

You are absolutely correct. Thermal shutdown is built into all modern CPUs. Sony has not implemented it correctly. I'm familiar with how it should work. My X60 sees a lot of abuse and a few times there's been so much gunk sucked up by the fan that there isn't much air moving. The machine heats up and it shuts down. That's what it should do. So either Sony has it set far too high or they just didn't implement it. My machine was seriously hot coming out of the sleeve, the screen was all distorted. Someone did say their machine had thermal shutdown when they OC'd their GPU. I think that was the GPU triggering that. OCing your GPU doesn't generally effect your CPU.

There is a sliver lining to my debacle. My machine was Microsoft'd, they customized the machine before I got it. Now it's not. I never got the messages telling me what's powered off before. I kind of like it.

 

The machine shuts itself down just fine. Sony's shutdown temp is 105c at the cpu core. This type of overheating can happen even if the cpu is not over temp. Your CPU cores could have very well been under 105c and the rest of the machine was around 90-100c. This is enough heat to make the machine damn hot and possibly damage other components, but the cpu was within spec.

Now could sony have implemented another sensor on the system board that would shut down at 90c? Sure.

 

Hot to us isn't shutdown hot.

To put it in perspective, 100c/212f is water boiling hot, we recoil in pain at much, much lower than that.



Also isn't the thermal shutdown supposed to just retard the cpu in steps in order to prevent a full shutdown?

 

Thermal "Shutdown" will simply snap the power off. Thermal "Throttling" will bring the multiplier down in rapid steps to the lowest multiplier.

Thermal "Throttling" usually happens at 95c.
Thermal "Shutdown" usually happens at 102c+. Intel's have a TjMax of 104-105c.

EDIT: Also, AFAIK, the GPU can't shut the notebook off. It has to have the command come from the CPU. So the CPU has to be reaching extreme temps for thermal shutdown to occur.

 

not sure about these i5 cpus, but my desktop i7 920 hit 100c (cooling system failture) and it only throttled It did NOT shut down! Luckily I've noticed that and shut it down myself

 

My machine is back. I love the easy transfer. Perfect way to save your account and files for the reinstall. I wished Windows 7 could reinstall over an existing installation like Windows used to be able to saving the installed programs and user data. That would have saved a lot of hassle.

Spoke too soon. I installed the new "fixed" TrueCrypt. It worked fine until I hibernated my first time. Now it won't start at all, even from a cold boot.

Got it to boot by deleting the TrueCrypt drivers manually. But now I'm back to hibernate not working. I think it's some crazy combination of TrueCrypt and deleting my recovery partition and sliding everything over to recover the space. I did test hibernation with TrueCrypt install before the recovery deletion and slide, it did work then.
