8886 - CPU overheat caused the case to MELT ( Pics Inside) - Page 2

It happened again !!!
Luckily this time I was sitting next to it and no harm was caused.

In the Power Settings, I have set the moniter to turn off after 2 minutes, the HDD after 3 minutes and the system to go into suspend mode after 5 minutes. The day this incident occurred, after working on my lappy for sometime, I moved my attention away from it. When I came back to it after 10 minutes, I noticed that the screen was out and the suspend LED was not blinking. I quickly placed and hand next to the CPU exhaust; it was hotter than usual and the fans were not running. I quickly pressed Esc, the screen turned on. There was dialog saying "Preparing to go into standby mode" and the machine had hanged. I quickly turned off the lappy by pressing the power button for 5 secs.

I have four OS's on my Machine Win98, Win2K, WinXP and Linux. I mostly work on Win2K, and both the time this problem occurred, I was using Win2K. I've installed Win2K from the original MS CD. I think that this problem occurs when my machine tries to go into standby mode and hangs during the switch over. This could be because of corrupt OS, but I'm not sure because every other application on that OS seems to be running fine, and there are no other crashes or hang ups.

Hanging going into standby mode and heating up =(. Hopefully Sager will have some info on this soon. I've been using standby in the 888X laptop for a long time with no problems. There's hundreds of members and lurkers that are probably doing the same thing with no problems, but I agree just a couple with a problem needs addressed and I'm sure Sager is taking a good look at it.

Very good info. As I know, Win2k isn't as good as XP for laptop. One of the reason is bad PowerManagement. I had problem even on my desktop that Win2K cannot switch to power saving mode.

Also, some application will interfere with OS too. Make things easy, before OS goes to sleep, it will ask every application to see if they are ok to sleep. So, there might be some bad application just hangs here.

If you know what you are doing, you can check the task manager, and system event log, or even perfmon to find out who's still running after OD wants to sleep. Kill that process and then to see if OS can go to sleep.

Ahh good point... I've noticed on my desktop Trillian will sometimes run 100% cpu forever when I close it - it's probably something like that. Let's figure this one out for Sager. Everyone who's had this problem, produce a list of apps that you have running.

It seems like the fan controls should be a separate circuit, independent of the operating system or CPU. It should also be separate from the circuits controlled by the on and off switch. When you shut down, the fan should continue to run for a short time until the temperature lowers enough, similar to what some cars with electric fans for the radiator do.

Since so far this seems to be a problem going into standby, I assume that if we set it to hybernate instead of standby, that the computer would be safe since it doesn't have to close the applications? What about a regular system crash?

standby mode...bleh...I've always seemed to have problems with hangs/crashes in standby mode (win98, 2000) on my laptop and another desktop. After leaving my laptop on all night only to wake up to it hung or crashed I ended disabling it completely. Now I just leave my laptop on all night and I haven't had any problems since (screen on and all). This may not be related but I thought I'd share my experiences with standby mode.

The one time I tried to put my 8887-X with HT enabled into standby it locked up. I was there and immediately did a reset so I don't know if it would have started overheating or not. However, 3 times now since I enabled HT the fans took off running and the CPU went to 100% usage twice and 50% usage once. The 2 times at 100% I was in Internet Explorer and the one time at 50% I was just messing around on it. Everytime I had to do a reset to get it to stop. I'm running XP Home. It does just fine in hibernate, but I disabled standby. I will do more investigation the next time it runs away with itself.

Just FYI

To fully take advantage of HT, you need an OS that supports multiple CPUs, such as Win2K, WinXP Pro.

WinXP Home DOES NOT support multiple CPU, thus, enabling HT in XP home only will create more heat. You won't get any performance gain.

XP Home claims to support multiple CPUs. It acknowledges 2 of them in my machine and it gives at least as good of a speed increase with SANDRA as the XP Pro machines I've seen listed here. So, I think it is getting the full advantage from Home. The problems I listed are similar to what a couple of other people running Pro listed about a week ago.

I'm told the new Keyboard firmware in the HT bios pack fixes any glitch that the few system you saw here had that led to the heat issue.

Just some more info on my meltdown:

I was running WinXP Home on a pre HT 8887 bios. The computer WAS set to go into standy after 10 minutes. I'm not sure if it actually went into stand-by mode or not before meltdown.

Now the good news:

Sager has sent me a new system already. Better news is it has the new bios already installed.

Thanks PCTourque and Sager.

Lucky for you.

I'm back in India. Getting a replacement for my sager seems to be very difficult now. I wonder if they could just send me the CPU Cover.

I've disabled suspend mode on my Lappy.

but that firmware flash fixes this problem?

-does this mean i can still setup my 8886 to standby on display close?

or should i disable standby all-together, i haven’t had any problems waking from sleep (i only dislike hibernate), but I’d shutdown more often to prevent any chance of that happening.

thanks,

BlueMeanie,
Yes with this firmware flash it's is supposed to take care of any chances of this happening and you can use your standby mode.

Anunay,
Contact Sager and see what they can do, they will work with you to take care of the warped cover.

I, too, have had heat problems (8886)

I, thankfully, haven't had nearly the melting problems that other people have reported (thanks for the pics!). However, this evening, I came into my office to find that the rear right rubber foot dealie-bob (the one near the heat vent, and, presumably, right over the heatsink) had sunk into the case a bit, since the thing had gotten hot enough to warp right there.
The computer is still running fine (albeit warm!), but it's a bit frustrating to have this beautiful machine w/ such problems. Perhaps Sager can help me out. I'll try them, and, if anything transpires, post what happens here.

Thanks all,
gardyloo

I don't see why this would happen... I've glanced through the technical manuals for the 8887 and the 5670 from clevo and the fan is controlled by a primitive thermosistor circuit, which means it should turn on when it gets hot, regardless of what the OS tells it to do, since it is in no way connected to the OS. Has this happened to anyone else?

I haven't seen the schematics but I can verify that Windows XP can will stop the fans. On several occasions I've had XP lockup going into standby and the fans subsequently ceased to operate. On one occasion I shut the lid went to bed only to find in the morning the keyboard temperature was well over 120F because the fans had not turned on!

I haven't had this occur in Linux.
