Weird shutdown P150HM

The strangest thing just happened........

I was surfing the net, not running any programmes except a couple of open documents in Open Office, plugged into the mains electricity, battery at 100% .... and without moving anything, the entire system shutdown with no warning BAM!

I was really shocked. First I checked the power cable hadn't become disconnected - no it hadn't. The blue light was still on on the brick. My household electricity supply hadn't even flickered. Nothing is hot.

When I restarted the laptop the battery indicator said 100%. Luckily I could recall my documents.

The laptop is 5 months old, the battery and brick are the one's supplied. I've never had anything like this happen with any make of laptop. What the hell happened do you think? It's very worrying.

 

^^^ Just closely monitor your machine for a while to see if it happens again. It may or may not be something to worry about. Keep us posted.

Off the top of my head....

Sounds like either a RAM issue or a virus.

Mr. Mysterious

 

You're not the only one, there are at least 2 others I know who have had this issue. I have experienced it myself 3 times, twice in the first week I owned my 8150 and once nearly a month later.

I wouldn't worry about it so much. I think it's one of those rare occurances that happens once or twice and doesn't happen ever again.

 

If you have the 285.38 BETA drivers, it's the culprit.

 

Thanks guys .....

It is odd it was so sudden and nothing to hint at what it could be. Larry I will keep you all posted I'm a Kobalt vicitm so this forum is all I've got!!

I don't think its a virus I am pretty vigilant on that score, have protection, don't click on weird things, haven't downloaded anything more than academic pdfs amd no P2P and anyway never heard of a virus doing that.... could they?

I love my Clevo I hope its OK

 

Is that the NVidias? No I'm still on the drivers supplied by Kobalt and while the Kobalt guys were naf at business I think they built pretty good machines. I haven't updated anything except the W7 updates.

Partck have you heard of this before then? And how would a driver cut the entire thing and not just say the screen?

 

I think Patrick is referring to the fact that those drivers he mentioned are beta drivers, and as with anything beta you can never have 100% reliability till the stable drivers are released. Going off what Mr. Mysterious says, you could always try eliminating the memory as a suspect by running a couple rounds of memtest86+.

 

sorry to be a muppet but what is that and how do I do it?

(was just looking at Windows7 event viewer but it doesn't mean much to me I'm afraid)

 

Hey no problem, basically you'll want to burn the ISO to a disc from their website: Memtest86+ - Advanced Memory Diagnostic Tool and boot to it by changing your boot priority in the BIOS.

Let me know if that makes sense or if you need some more help

Edit: Also, I should explain that it simply runs a series of complicated tests in order to test your RAM fully. You'll see errors in red pop up on the bottom right-hand corner of the screen after you've started running it if there are problems with the RAM.

 

OMG I just found memtest86+ man that's serious I can't even work out which bit you download let alone what you do with it....

shall go and have a root about but dios mio I like a button that says "download" !!

 

I have had this happen few times also, system just turned off. Never even played a game on it yet...

Don't bother testing your RAM. Bad RAM will not cause a system to turn OFF, it could cause it to BSOD or reboot though so if you rebooted of course ignore the above.

I wonder if its some bios bug or actual hardware issue. Bad part is not really reproducible for those of us having it as its so random. Most say don't worry about it but come on, that's not normal.

Would you say don't worry about your car if your on the freeway and it just turned off but started back up fine? Of course not, you would be like . The issue though is finding out the causes, which we never may....

Sucks because I have this laptop but am afraid to go any place with it though I shouldn't be....

If I had to guess cause I would say Mobo or Bios bug.

 

Well you have the same laptop as me except I have the GTX460M.... So you had the same thing happen too? weird isn't it.

Anyway I downloaded memtest86+ and can't even figure out how to open it (I also downloaded 7zip) or what to do with it.

I agree about the worry... of course I'm going to worry. The reseller I bought it off has just gone (female curves - silly censor) up so I don't even have warranty. Also your bug theory is a very valid possibility and if so as many people as possible who encounter this problem need to make a noise.

How long have you had your laptop?

Ahem.... I said I was a muppet no? Just seen the bottom half of JP's post explaining I need to burn ISO to disc

THanks JP... please see post below.

 

Well here's another one:

Hi JP

I guess I unzip the tar file and burn that to disc.
Then change bios to boot from D Drive.
Then shut down and reboot?
when I've run the tests do I have to change the bios again before I reboot again.
( 'Cos otherwise how to I boot if the bios is set to boot from D Drive?)

I won't do it tonight because I'm in Europe and its getting late so I'll give it a go in the morning because I do think that any tests that may help isolate the problem are important even if it is just to rule things out.
And like I said I love my (no warranty) Clevo.....

 

Grab the ISO file on that website then use The Official ImgBurn Website to burn the ISO directly to a disc. You don't need to unzip the files. ISO files are just CD images basically. Once you've burned the ISO onto a CD, go ahead and boot to it. It is worth a try just to eliminate it as a suspect.

 

Below is a image file link to the latest memtest...

memorytest420.iso

infrarecorder is a free, and by far most user friendly, image burner I have found. You should definitely use that program if you want to burn an iso in my humble/honest opinion.

Or you could do a linux boot and do a memtest that way. At least I think you can.

 

Larry thanks for that muppet-proof link I really appreciated it!

Ok guys I ran memtest for 24 hours = 14 passes

It says 9 errors (but in the count it missed no 6) so I figure 8.....

Luckily I wrote down the summary because it doesn't look like there was anywhere to save the result to. It only offered print when I looked in the configuration....

The errors were found when running Test #4 and test #8 All of them show up around addresses that end 4328.6mb to 4399.7mb They were found in the 1,3,4,7,8 passes..............

Don't know if this is what caused my random shutdown or what but I suppose it looks like dodgy RAM anyway. I have 2 x 4gb so how do I know which one? Or do I have to replace both?

Naturally I am uttering curses at Kobalt, sticking pins in imaginary dolls and wishing a plague upon their forebears at this point in time seeing as they probably didn't test it properly, or more importantly, have left me with no warranty. I hope this is the only problem.............

The memory is Corsair I believe - can I send it back to them if I identify which one (or both)?

IS there anything else I should do? What do you guys think please?

Thanks so much by the way all of you.............

 

I'm answering my own question about returning RAM to Crucial (Corsair) the answer is No only through the reseller.

 

Luckily RAM is getting pretty inexpensive nowadays. If you'd like you can try removing one stick and then running the test again, that way you can remove stick after stick to narrow down the culprit. If your warranty is through Kobalt, you might try contacting Corsair to see if they could do anything.
