Laptop shutdown with no reason or errors.

[jlsdust]

System;

Acer Aspire 5720 z
CPU: Intel Dual Core T2310 1.6 ghz
RAM: 2 GB
Graphics Card: Mobile Intel Graphics Media Accelerator X3100
HD1:80GB
HD2:80GB
OS: Window vista professional
Antivirus: Symantec End Point protection V.11
Adware: Superanti spyware.

Symptoms:

Computer random shutdowns, especially on high CPU usage such as video convertions, or video streams online.

After the shutdown I'm unavailable to restart the computer for a while. WINDOWS don't boots after several attempts. No safe mode or anything. No beeps either. No error display. I usually wait about 15-20 min. I restart the computer and a message display said that windows didn't shutdown properly with the option of safe mode, safe mode with network, safe mode with command prompt or normal restart.

I have done it all, safe mode malware/adware and virus scan. No detections. System restore to a date before. Disk check for errors, system repair, etc. Finally System restore to a Factory Settings (Window Vista reinstall and reformat HD1)

Computer works fine for a couple of day, until shutdowns started again. I install speedfan to monitor the temp. idle temp is about 75C average. On full load 95C-99C. Especially when streaming videos online.

I was watching a video on megavideo when the first shutdown happend after the Factory resetting. Second time, video convertion with videora for my ipod. Then so and so.

Don't know what else to do.

The max operating temp for your processor is 100 deg C. The temps you report are very close. I suspect that the symptoms that you describe are related to the processor shutting down due to high temp - the activities you describe are high CPU utilization activities.

1) Use a vacuum to clean around the air intake and discharge.

2) Clean the airways as best as you can. Remove any bottom panels that you are comfortable removing and clean away dirt and dust with a can of compressed air - clean the fan but stop it from overspinning.

3) Always use a laptop on a clean, level, hard surface - never on a lap, bed, etc that may restrict air flo into the air intake.

Best of luck.

Thank you for reply. I use my laptop over a cooling pad. Also i already clean the CPU fans. I'm testing my computer with a fan close to it. Haven't shutdown yet. But i notice that the CPU temp raises really quick from idle to full load. It goes from 65C to 90C in matter of seconds when I'm converting a movie.

Is that normal. I mean, this laptop is less than a year and having that kind of problems so soon...

Yes, the rapid rise in temp is normal for that type of activity; it is not normal to exceed thermal limits.

Is your notebook under warranty?

Do you hear the fan run (and changing speed) when you use the notebook?

Are you comfortable removing parts of the case to try to clean the inside?

Yes laptop still under warranty, but they want me to send it to Texas I live on Washington.

Yes, I'm constable  moving parts and working with computer components.

And no i haven't hear about fan run.

Since the laptop is under warranty, I don't think that you ought to take anything apart, buybut, rather, get it fixed/replaced under warranty.

I'm unclear about the fan - does it work or not? Regardless, I suggest that you follow through on your warranty.

Best of luck!

Actually the fan do work, but i guess it isn't working good enough to kip the CPU cool. I have use my laptop all day with a fan directly to the back converting video and the full load temp doesn't go pass 91C.  Write now is 81C and I'm ripping a movie.

Is any way to increase the fan speed using a software or BIOS? I'm not too familiar with it.

You're under warranty - my suggestion is to let the manufacturer deal with it.

Yes, before you void your warranty.
