Lenovo Z570 shuts down

rjohmit 142 February 24, 2013 at 10:19 AM
Hi all, I have a Z570 2nd Gen Core i3 laptop I bought in October of 2011, and its begun to frequently (multiple times per day) shut down unexpectedly.

Its not related to overheating...its sitting on a wood table so the vents are clear. And we could be doing something as simple as typing an email or browsing the web when it will just shut down...like someone suddenly pulled the plug and the battery at the same time.

I've done some research online and turned off some programs in Startup of msconfig. One post mentioned a couple Lenovo energy management utilities. But this hasn't worked.

Anyone have any ideas? I'm thinking about raising hell with Lenovo Support. I know its out of warranty (by a couple months) but I'm usually pretty successful when doing this.

A laptop should last longer than this and I really can't afford to replace this machine right now.

Could be RAM, could be CPU, could be something physical. Have you tried turning it upside down, opening up the panels, checking for any dust, accumulation, perhaps check for any type of heat damage, burn marks, any cabling that may be frayed or shorted out. It may not be software related and could be physical.

Does it do a proper shut down, or is it a crash and when it boots back up, it offers an option to repair or boot normally?
As mentioned above, it might be hardware related, but it could be the OS itself.
As you are sure that it's not a heat problem, perhaps you could save all your data and do a factory restore.
After doing so, if it continued to crash/shut down out of the blue, then you'd be sure that it's a hardware problem.
The only hardware thing you can easily do now is to remove the ram, clean it with contact cleaner or alcohol, then replace, on the off chance that it needed to be reseated, but the odds of that being the problem are extremely low. Nevertheless, it can't hurt to do it.
There's another option you could try. Assuming the problem is a recent development, you could do a system restore to a date preceding the beginnings of the problem, to see if that solves it, and if it does, that would tell you that a program a driver or an update/upgrade that you have recently installed, is responsible for your issue.

Appreciate the replies.

You'll be in the middle of something and it just dies without warning, like someone pulled the plug/battery at the same time. It doesn't shut down Windows...it just turns off completely. Sometimes it comes back on itself and starts to boot up Windows, sometimes you have to press the power button to turn it back on. When you manually turn it back on, the DOS-looking screen appears saying Windows didn't shut down properly.

I'm positive its not heat-related. It can be just sitting idle (but not sleeping) and it'll shut down. I did a factory restore before this all started, but I'm not opposed to doing it again. I'll check out under the panels on the bottom and see if anything looks unusual. I can maybe try swapping out some RAM.

The event viewer doesn't show anything that would help me diagnose the problem. There are alot of "Kernel Power" (41) events, which tells me Windows didn't shut down properly...I kinda already knew that.

By the way, it does this whether its on AC or battery...

No, I've started out trying software stuff...but I will do that. Thanks.

I doubt that it's worth doing the factory restore again.
Had it been a software/OS issue, the first restore would have fixed it.
It's clear now that we have a hardware issue.
You can try the ram thing, for what it's worth, and download CPUID hardware monitor or Coretemp, to monitor your internal temps, just in case.
After that, one would have to believe that the mobo has gone whacky and it may need some major repair or replacement.

Just wanted to follow up. Opened up the bottom of this machine...nothing exceedingly dusty or ususual, fan seems to be working fine.

But I swapped in the RAM from another laptop and this machine seems to be stable now. I'm typing this post on it. =D

Appreciate all the replies. We wound up getting my wife a new laptop anyway, so this one will end up being used by the kids and now we won't have 3 kids fighting over 2 machines. Everybody wins!

If you think it's ram put the bad memory back in, and run Memtest for a few loops. It should confirm the ram is bad. You should be able to pick up new DDR3 (Assuming thats what this uses) for well under $50

Thanks, I'll try that...but assuming the RAM is bad, the RAM from the other laptop should work fine in this one. The other one is a POS HP 630, which is nearly useless because it executes a thermal shutdown any time you do anything remotely taxing (and the fan sounds like a jet engine). If you do a quick google on that laptop, you'll find all kinds of complaints about it.

I may try a laptop cooling pad for the HP 630....it might be useful to the kids for school work, flash games, or maybe even Wizard 101.

It's extremely rare that ram just goes bad, but it's quite common for it to need to be reseated/cleaned, and that may very well have been the case with your system.
It's a more prevalent problem where I live in the tropics with all the salt air, but it can happen in North America too and it's an easy job to find out if that ram is still good by cleaning it and putting it into either computer, just to avoid throwing it away for nothing.
Glad you got the problem solved.

When you have it plugged into the wall, does it still shut down?
