My laptop toshiba satellite a210 is almost 4-year old one. The first repair for the laptop was a year ago. From its first day in my hands until 2 months ago, only remaining trouble was its noise because of heating much. However, in time i also encountered such a stupid trouble like Shutting down by itself without any warning. I got my laptop
and took it away for the second repair yesterday. They solved the noise problem, but it still keeps shutting
itself down. It did it Two times again.


Im starting to hate this laptop , what should i do?

Hi Kobem,

Is the fan and heatsink clogged with dust causing it to overheat ?

Is there anything in event viewer indicating a reason why it shut down?

Sounds to me like your CPU fan was defective causing your laptop to overheat and i would like to think they have replaced the fan, your CPU will shutdown your computer when it reaches around 60c to prevent any serious damage.

You need to find what is causing the CPU to overheat.

Is there thermal compound on your CPU?
Is the heatsink secured down correctly?
Is this a known good fan in your laptop?
Does the fan spin when you power on?
Is the air intake on your laptop blocked up?

If you took your laptop to be repaired and paid for it I suggest you take it back.

Hope this helps

 

Do you have temperature monitoring software installed?

 

Hey, thank you for your assistance. Nevertheless, i suppose there is no longer fan issue according to my observation. I can not realise the exact cause

 

here is the image showing temperature of CPU cores momentarily

 

+1 i think you will need something like speedfan to monitor the temperature as if the machine just powers off without warning then its likely to be the cpu protection circuit kicking in. If you have windows 7 then you can alter a few advanced power management settings that may help keep the temps down.

EDIT: ok ignore me!

 

so does that mean you actually installed some software to see what the cpu temp is or are you just assuming since the fan isn't loud anymore that it is cooling fine? there are many free utilities: core temp, real temp, speccy are a few that come to mind that will tell you your temps

did you look in event viewer? you might want to make sure it isn't set to automatically restart on system failure to make sure you aren't missing a BSOD error.

edit: I was too slow with the post I see the image now.

 

Then, watch this

 

Do not use speedfan for temperatures. It is innacurate use core temp or real temp instead.

All that crap on your desktop (the shortcuts) will be using memory and could be slowing things down.

 

just shuts itself down. I detected something however, two weeks ago i began to use ESET smart security. From
that day, laptop had hard times even refreshing web pages. I mean, application(ESET) along with Zone Alarm
Internet Security Suite caused my computer get exhausted. Nevertheless, I needed ESET cos Zone wasn't working properly anymore.

Sometimes, even i don't realise why this laptop stops listenin' to me

 

This may be part of your problem.

You have got 2 anti virus programs on and 2 firewalls on the machine at the same time. There is no wonder that the laptop takes ages to refresh web pages. If the Zonealarm suite isn't working - uninstall it.

NB

 

also you do realise that running two firewalls and two anti virus suites can conflict with each other?

I run ESET and I have never had an issue.

Again please check event viewer.

 

No issue shown from the event viewer. what i have done recently was removing ESET software then
changing power plan of the computer.

 

read what I put kobem, the issue could be related to the fact you were running ESET smart secutiry and zone alarm. running two firewalls isn't a good idea.

 

Shortcuts shouldn't use much memory, lnk fies are small and it only needs to pick the ico file once from whicever cache it is contained in. Upon bootup, it can take time for these to be displayed as Windows may need to find the ico file in a DLL or EXE, but once running, shortcuts on a desktop should use very little ram and hardly any extra CPU activity to dsplay. Do the test yourself by creating a bunch of shortcuts on your desk and monitoring CPU/Memory usage.

 

SIMS 3 *shudder*. There is your problem right there.
