Type 8600M DEFECT on google to find out the story. This laptop would be a no sale to people I run with.
Sorry to hear you are having issues but this sort of machine should run hot and my best advice is to get as many years of warranty as you can.
I don't know if it will be helpful, but it can't hurt so here are my specs:
CPU Full Name Intel(R) Core(TM)2 Duo CPU T7700 @ 2.40GHz
Display Adapter NVIDIA GeForce 8600M GT 512 MB
Memory x2 Mushkin 1 GB DDR2 333MHz
If any other info would be helpful just asked.
Also, the laptop was purchased in March, so is less than 1yr old.
So here's the problem. I usually leave my computer on overnight for various tasks, e.g. running virus scans, and I had never had any problems. Then, a couple weeks ago, maybe the week of the 15th, I woke up to find out that my computer was off. A little odd, but I didn't think much of it, so I pressed the power button but it didn't turn on. A little scared, I decided to take the battery out for about 5-10 sec and see what happened. I put the battery back in and everything worked perfeclty. I figured it was just a freak incident and went on with my day. But the next day I woke up to find the very same thing, and this has repeated extremely regularly every single night since.
Eventually I realized that the system would just totally crash, no normal shutdown or anything within basically the same hour every night. After looking at the system log, a couple of times recently that is has crashed are
02:06:11 on 31/12
02:59:08 on 30/12
(29/12 was a freak day I didnt have my normal schedule so I won't report the time here)
02:12:02 on 28/12
I wake up at about the same time everyday, so I figured it was crashing about the same time every night because for whatever reason the system would only stay on for approximately the same time every day, so I checked the respective boot times in the system log and found:
10:30:00 on 30/12
11:26:55 on 29/12
10:18:47 on 27/12
A little math (assuming I did the arithmetic right) said that the system was on:
15.6031 hr on 30/12
15.53694 hr on 29/12
15.8875 hr on 27/12
To me, those numbers are amazingly close.
Anyways, I knew I had set up my antivirus program (AVG) to perofrm a system scan everynight at 2:00:00, so given the times I recorded, it seemed logical that the scan might somehow trigger the shutdown, so I performed a little experiment.
If the AVG scan was causing the crash, then if I performed the scan during the day that should also cause it to crash. But no, nothing. Yeseterady I did the scan midday and everything worked perfectlly, no crashes, nothing. I also decided to see what disabling the system scan at night would do, so I disabled the scan last night. I woke up the for the first time in weeks today to find out that my computer had no crashed, so I figured that, for whatever reason, the AVG scan caused the laptop to crash but only during the night (pretty weird if you ask me). But as I was doing some work this morning, my computer crashed around 11:30. For whatever reason, not perforing the scan only prolonged the priod of time which the computer wanted to stay on without crashing.
I then suspsected that the problem might be caused by overheating, and that the scan led the computer to overheat itself faster, so not peforming the scan would increase the time it takes for the computer to heat up (this explanation doesn't seem perfect to me, but it's the best I can come up with now). So I clocked my proceesor's temps this afternoon after the crash to find:
core 1 temp: 87 degrees C (189 degrees F)
core 2 temp: 86 degrees C (187 degress F)
HDD temp: 51 degrees C (124 degrees F)
After a little bit of reserach, it seems clear to me that my computer is hotter than it should be (agree / disagree with me here?). But I don't see if overheating were the problem how the crashes could follow so regular a pattern.
Is overheating the culprit? If not, what could it be? And most importanlty, what the can I do to fix the problem?
This was kind of a long post, so thanks a bunch for taking the time to read it and help me out!
