Improper shutdown of laptop

By bhatnagar_nitin ·
Hello,

I have a compaq presario 2100 laptop. These days I am facing a weird problem of it getting shutdown without any notification. While I am working on it, the notebook shuts down automatically at any time without any notification. I don't think that there is any virus/sasser worm on the system cause, even sasser worm gives a notification of 1 minute shut down time in windows. I strongly see it as a hardware issue but I don't know what it is. Could anyone help me understand the issue and how can I resolve the same? Due to this I am not able to work any more on my notebook as always it keeps me stranded.

Thanks,
Regards,
Nitin

Does the system restart after the shutdowns?

If yes, you might have Windows system failure. Disable Automatically restart from Start and Recovery settings. This will produce a BSOD that might give a clue of the problem. There also might be a heat issue. Touch the bottom of the laptop to see if it is hot. If it is, check whether the CPU fan is working. You may have to clean the CPU fan and heatsink.

If no, check Event viewer (Application and System) for errors. This may give a clue whether any service, application or Windows cause the problem. If there was no error, you have a hardware problem.
Do a diagnostic test on HD and RAM. If you still have the problem, it is most likely the motherboard (rather than CPU) was the cause.

No, the system doesn't restarts. Actually it shuts down though the battery is powered on. I already checked the event viewer and there is nothing helpful in it which can state the cause of shutdown. My notebook CPU and fan seems to be ok as the heating is as usual from the bottom side. Still, there is something which I am unable to figure out. This is strictly a hardware problem that's what I can say because windows is starting normally everytime I reboot it without any failure notifications. Any more clues on the hardware side may be some sites etc would be helpful.

I tend to agree heat is the most likely cause of this problem. You'll need to make sure that the air intakes are not blocked by something loose on the desktop like some form of cloth or other covering. When the CPU Fan/s start up they can quite easily suck up some cloth covering and block the air intakes so that the CPU overheats and causes the system to shut down rather than burn out the CPU.

For a full diagnostic testing regime you can use the Ultimate Boot CD available here

If everything passes without a problem try a Live Linux and see if the system runs properly without shutting down. These versions of Linux load off a CD or DVD and have everything necessary to run the system but do not write anything to the HDD so there is no possibility of doing any damage to the Windows installation. If everything works properly with a Live Linux which you can generally pickup on a Mag Cover as a Cover Disc you have a Windows Problem.

If it's an overheating issue you can pickup one of those NB coolers that sit underneath the NB and allow cool air to circulate around the air intakes. I've personally only ever used the Antec ones like the one here

But there are many others available which should do a similar job.

Along with HALS response, check the battery for fault. Plug in AC and REMOVE the battery completely. Does the problem still occur???

Yes you are right. The third answer I suppose is the best shot to the culprit. I revisited my notebook from all sides and found a special reset button which I guess resets the notebook to factory defaults. When I pressed that button and restarted my notebook, everything worked fine without any hazards. I guess the culprit in my case was the battery. But I am still surprised that the Compaq 2100 battery is so poor that it shows as 100% charging remaining in the taskbar. Recently I just caliberated it using the utility provided by compaq. This might be a good feedback for compaq guys and I must say thanks to all of you who helped me in overcoming this problem.

Best Regards,
Nitin
