8890 severe crashing - help!?

post #1 of 28
Thread Starter 
Folks, I'm having real trouble with my 8890, which has been an absolute dream until just this month. (it's 4 months old and under warranty, thankfully). I've been lurking these forums since before my purchase and have been amazed by the sheer volume of useful information here. Well, I could use some info now!

I purchased my Sager 8890 from PCTorque.com in November 2003. On Friday, the system crashed hard while running Excel and a few other programs. I was unable to reboot, despite powering all the way down, waiting a minute, and then powering back up. Sometimes the PC would POST and then hang after detecting IDE devices, other times it wouldn't POST at all.

After three or four tries, I was able to get back into WinXP Home and fortunately was able to back up my data to an external hard disk. However, the system has continued to crash frequently. These are apparently not application related. Crashes are occuring when many apps are open, when no apps are open. They also seem to occur whether or not an external hard disk, network cable, or power cord is connected to the system.

I should note that for the last month or so I have noticed an intermittent boot issue. When I would first start the PC in the morning, I would sometimes come back to find that it had not reached Windows. Rather, there would be a blank screen with a blinking text cursor at the top left corner. My assumption was that a cold hard drive was the culprit. Confirming this was the fact that every time I tried booting again, the notebook would start up normally. Clearly, that intermittent problem (occuring maybe once or twice a week for about a month) was a warning of something more serious.

I should note that this PC has been almost entirely desktop bound and has taken very little physical punishment.

I'm pretty good with hardware, and I have to say this issue seems disk or disk interface related. I've not noticed any unusual noise coming from the disk, nor have I noticed any disk error messages. The only "symptoms" I noted prior to the current crashing is the fact that boots would occasionally fail. Several diagnostic steps on the drive revealed no issue:

1. Checked Windows Event Viewer logs. No obvious disk related failure reported
2. Ran a full Windows Check Disk scan and repair. The test came up clean--no errors.
3. Downloaded the Hitachi disk fitness test from the hgst.com web site. Ran both the Quick and Advanced tests. Both tests passed--again, no errors.

OK, so the problem isn't the disk platter. I haven't ruled out a memory failure (though the intermittent pre-POST failures seem to make a bad memory stick an unlikely candidate). I'll run MemTest in the morning to see what comes up. In the meantime, I'm wondering if there might simply be a loose drive connection or perhaps a short circuit related to the drive interface? If so, would it be appropriate for me to open the case and check the fit of the connections? This PC is under warranty and I certainly don't want to do anything to void that at this stage.

I've contacted tech support by email yesterday and am awaiting a response. But in the meantime, I'm hoping there might be some way to narrow things down. Thanks so much in advance for any help!

This is a real poser. No physical trauma, no obvious event, disks seem to check out. No apparent common event to the crashes. And it does not seem to be a heat issue as its crashing up start up, does that happen after a immediately prior crash or just anytime?
When it crashes, is it a total shutdown or what? No error messages? No BSOD? Just dead?
Certainly could be connection issue, though if you are essentially deskbound, there doesn't seem to be any movement to que the crash. I think if the disk connection was to blame, you'd be getting something on those tests.
I suppose a RAM stick could have gone bad but that's really rare, they are generally either good or bad from the start.
Do let us know what it turns out to be, assuming you figure it out.

New Information: Heat?

Exactly right. My working theory now is either simple (a loose connection that's being affected by fan vibration and occasional movement) or huge (an intermittent short in the controller/motherboard). I'd love to crack into this thing and check the connections, but I don't want to void my warranty. Anyone know what's allowed there?

One thing I want to come back to is heat. The 8890 blows so much hot air out the right side that I constantly worry about heat buildup. Now, I've had those failed early morning boots, but my problems in the past 48 hours have occurred after being up and running awhile. Immediately after these recent crashes, I think I have a hard time getting the lappy to boot back up (I get failed POSTs or hung IDE detects). But after waiting a spell, I can usually boot again.

EDIT/ADD: I just ran the wonderful MobileMeter utility. My PC booted fine this morning, with initial temps of 47C CPU and 26C HDD (I have a single 60GB 7200rpm drive in there). After 9 minutes 45 seconds, temps stood at 47/29 (CPU fan cycles on at 55 and off at 45). I started an AV scan. To avoid overheating, I had placed my 8890 on a book to provide more air clearance. At 23 minutes, temps were 51 cpu/38 hdd. I placed the laptop on the table to see if temps might spike. About three minutes later, the PC crashed (yes, before i could look at the meter, darnit).

When I tried to reboot, I got into a cycle of boot-POST-IDE detect-Win splashscreen-reboot. That's definitely what I'd expect when recovering from an overheating component. Question is, what's overheating? The CPU fan seemed to do a wonderful job of lowering the chip temp, though the HDD temp was on a constant uphill slope regardless of fan activity.


Could it be something as simple as a dead fan or blocked vent? Hmmm....

FYI, some of the recent crashes have gone to a blue screen. There's text up there about some manner of catastrophic failure, but it's gone so fast I can't read it. I know I haven't seen anything like a divide by zero or parity error, which I usually associated with memory failure. The mystery continues.

Low-level detail

Still no answers. But I do have some detailed info. Basically, here's what the Windows memory dump says on the blue screen (there's a photo included below):

*** Technical Information ***
STOP: 0x0000008E (0xC0000005, 0xBF87B987, 0xAFD6BC14, 0x00000000)

*** win32k.sys - Address BF87B987 base at BF800000, DateStamp 3f73195d

From what I understand, the 0x0000008E error message is typically memory related. So could a stick of RAM be going bad? Seems unusual--that stuff either goes early or goes late, but not after four healthy months. Ah well, I'll yank a SODIMM and see if I can get to the bottom of this.

FYI, I've used the MobileMeter utility to measure CPU and disk temps. CPU temps are cycling neatly from 45 to 55C, as the fan kicks in and out. HDD temps are increasing steadily regardless. I'm noting failure as temps get to about 40C on the HDD. Not saying the HDD is the failure point, but perhaps the memory or northbridge chipset is getting too hot?

Hi, regarding this:

I should note that for the last month or so I have noticed an intermittent boot issue. When I would first start the PC in the morning, I would sometimes come back to find that it had not reached Windows. Rather, there would be a blank screen with a blinking text cursor at the top left corner

This happens to me sporadically too, on both my 8890 and my prior 8887. I haven't really thought twice about it, as it's never seemed to cause any problems for me. I just hold down the power button and shut it down, and boot it up again and it always works. Not sure why this happens. The only time my 8890 was constantly crashing (BSOD within minutes of boot) was when it first arrived, and it turned out to be bad RAM. I had them ship me a new pair.

Good luck to you.

Thanks Vex.

I just pulled one of the DIMMs (I have a pair of 512GB PC3200 RAM sticks in there). And wouldn't you know? The PC is now running flawlessly. I ran a full anti-virus scan, which pumped the HDD temp all the way to 48C or 49C (CPU temps never got much past 55C due to active fan cooling). No crash.

Looks to me like the stick I pulled may be bad.

One question. The heat spreader plate that sits beneath the keyboard has a rectangular indent that seems designed to promote contact with the underlying DIMM. There's a pink, kinda rubbery rectangle of material on the down side of this indent. Is this used to transfer heat from the DIMM to the spreader? Or is it intended to protect the DIMM from a hard impact transfered through the heat spreader?

I dunno. I pulled the DIMM that doesn't lie under this indented rectangle and the corresponding material, and now all seems clear.

So I'm worried if I swap this 512GB stick for a new one, I'll be right back where I started in a few months. Could thermal stress have killed that stick?

Yay on the memory victory. That seems to be the problem. Don't know about that rubbery thing but soft rubbery stuff is generally not a good heat conductor though I suppose it could be a thermal pad of some kind. I've never heard of something like that between the memory and the heat shield. I'd suggest you try to find a service manual for the 8890 and check out whether its supposed to be there at all, though since there's an indent in the shield, it would seem to be what they intended. I am just wondering if that indent is pushing on the SODIMM and causing the problem. Could be when it warms up, there's enough expansion to make the contact then you press on the keyboard and .... ZAP!!

Can any other 8890 owners comment on this indent and the pink rubbery thing?

Have you tried just swapping the sticks to see what happens? If it works with either stick then you need to look at that rubbery thing and what its doing.

The 8890 runs dual channel memory so its important to have both slots filled. Try swapping the sticks, if the problem persists, you know its the memory and you can replace it, unfortunately, its supposed to be matched pairs. I take it you are still under warranty so they should replace the pair. Ask for a cross-ship on the replacements (that's where they ship them to you and then you ship the defects back once you have installed the replacements). Meanwhile, you need to figure out why that memory went bad. I'd talk to Tech Support and get my hands on a service manual, good thing to have anyway. I think a forum member has them for download, do a search.
infinity306 has it on a private site, http://www.vreal.org/sagerforums/D800P_SM.zip, I checked it, it works. Very fast too, thanks infinity, you da man!!!

Looking in there, the picture on page 36 of item 4, shield plate, doesn't look like there's a indent, though on the parts diagram there appears to be a Keyboard Support Plane Nodule (#4 on page 51) that does. I don't know. I hope this helps.

While you're at it, I'd do a thorough cleaning and connector check. Apparently the cleaning and Arctic Silver treatment does not void your warranty since there's a STICKY in these forums on doing it and I'd think PCT would note that's a problem if it was. I believe as long as its a user servicable part, you are OK, that includes a lot of stuff. I think there are stickers at any screws that would void the warranty but then again, I don't know for sure. Proceed at your own risk. At the least, its worth an email to PCT and/or SAGER to clarify.

The more I think about it, the scenario of that pink pad pushing on the SODIMM and twerking the connection the more it makes sense. Definitely try swapping those SODIMMS.

Good luck and let us know what comes of it all.

Is the ram you have from APACER?

If so ,I had the same kind of problems with the Apacer ram my lappy shipped with.
They died one at a time, and were replaced with kingmax brand which to this date has been working well.

very interesting...

Grantski,

Yes, in fact they are Apacer brand memory. Good to know about this.

Bad news by the way. This morning I booted my PC (on the one "good" DIMM) and got that blinking cursor failed boot thing--the one I attributed in the past to a cold hard drive. I rebooted and the PC launched Windows normally. About 20 minutes later, though, I got another sudden 0x8E crash. Exact same BSOD message.

Man, I really don't want to have to send in the whole PC and lose the thing for two weeks. I got work to do!

You shouldnt have to, I just had Sager cross ship me the ram, and I installed it myself.

swapping ram

Grantski,

I've talked to Sager and am having a new set of RAM shipped my way. We'll see what happens...

I think that should resolve it, matter of fact..hehehehe I am 99 percent sure
Let me know please

*Turns green with envy, 2 weeks after her 8887 warranty expires and her system goes to hell and grows especially fond of the BSOD*

My, what I would do to be without my lappy for two weeks and have it come back to me in pristine, lovely; working condition.

Have you tried changing up your RAM Trewin? Or cleaning out the lint and dust bunnies? Or checking your connections or ... ... ....?

More pain

Anyone have any thoughts on cutting through the BS with the Sager tech support folks. The callback thing is awfully tough at times. I'm waiting on an email from them so I can get this RAM cross shipped, but nothing has shown for 4 hours. I figure they have the address wrong.

But I can't just email this guy and let him know. And i can't leave him a real message either. I have to wait for a call back and try again. Meanwhile, I've got $10,000 in active projects stuck on that freaking laptop. And my deadlines are hot hot hot.

Any suggestions or ideas?

Thanks!

This has been discussed in length (search the threads).
When you call Sager , you are talking to techs that build and test these lappys.
The other way it could go, is instant answer on the phone, from some idiot in pakistan that has never seen one of these machines, let alone build of test them.
I am not crazy about the call back proceedure, but I will take it any day over an outsourced tech joint out the the country.
Maybe we can get Sager to hire Aussie for tech calls

Huh? What are you talking about? That question was to Trewin, not VTdesmond m, and Trewin didn't specifically note her machine's symptoms, just that she'd like to have it come back pristine.
