Thanks, I will see to check it:)

I have been dealing with this shutting down of my Toshiba laptop for a couple of weeks now. Fans are cleaned and it was working non-stop after that, but now it seems that it is OK as long as battery doesn’t start charging. Then after a while the laptop shuts down. Could it be a problem with power supply, ie. power voltage drop?

I think the next step would be testing the laptop with another AC adapter. If the problem persists this could be motherboard related failure.

I just got my laptop’s IC reheated for about 2weeks now.

Not sure what it means.

i still have problems with overheating since it’s getting hotter when I use it for longer hours. can anyone suggest what should be done?

1. Make sure the fan spins.
2. Make sure the fan and heatsink are clean.
3. Replace thermal grease on the CPU.

yep its getting hot when playing game but my fan is running

Have you tried cleaning the heatsink? It’s possible the heatsink is clogged with dust.
I don’t know what else could be causing the problem.
If the fan is running but the laptop is getting hot most likely it happens because the heatsink is full of dust.
Buy a can of compressed air and spray it into the fan grill on the bottom (of side of the laptop) until all dust is gone.

Take a look at the cooling fan. Does it start at all? Does the bottom of the laptop feel hot when you running games?

You will have to tell me how to do that! LOL! I can rip things apart if mechanical, but have no clue how to do what you suggest!

Take a look at this guide:

It shows how to disassemble the laptop to barebone system and test with an external monitor.

FYI: today the laptop is running perfectly, and last night it kept shutting down repeatedly.

Unfortunately, your problem is intermittent and it’s really hard to tell what is causing the problem.
Could be motherboard failure.
