Having problems with your Toshiba Satellite A75-S206 Notebook ?

My Toshiba Satellite A75-s206 shuts down by itself. When I feel the bottom it's burning hot. Could this be my fan not working properly? Please help.


Answers :

I own one and just came across the best solution.  I'm assuming by shuts off, you mean it just completely blinks out in an instant without warning - this is the processor getting too hot and shutting off to protect itself.  First you will make sure the fan & heat sinks are clean and working properly, then you will enable the power management features of the processor (Toshiba's power utility does not do this).\015\012
\015\012First, of course, get the canned air and blow out all the fans and heat sinks so they can work properly.\015\012
\015\012Next, download and install the RightMark CPU Clock Utility (search google for it).  It will take a little reading up to figure out how to use it, but here's the basics:\015\0121. Go to the "profiles" page \015\012\011a. under "Profile Selection" set it to use "Performance on Demand" for both AC power and battery (current and startup). \015\012\011b. Then hit the "Defaults" button at the bottom, and then hit "Apply"\015\0122. Now, expand the "profiles" tree (on the left side, there should be a little + next to it) and go to the "Performance on demand" profile and do the following:\015\012\011a. Click the "CPU Settings" button at the top.\015\012\011b. Hit "Defaults" at the bottom of the page\015\012\011c. For both AC power and battery, check "Use throttling", and then check all the indexes (0-7) in the list below.\015\012\011d. Below that, set the "target CPU usage level" to 75%.\015\012\011e. Hit "Apply"
\015\012
\015\012If that all works properly, you should be able to go to the "Monitoring" page and watch your processor throttle up and down automatically as needed.  You should find that within a minute the fan gets a lot quieter because the processor is so much cooler.  Now that it's running properly, you can open the "Settings" page and check the boxes "start minimized to system tray" and "Run at windows startup", now it will run completely automatically, you won't even notice it except the fans will be quieter and your battery will last longer.\015\012
\015\012What it does: this laptop uses a Pentium4 processor, and by default WindowsXP does not manage the processor power settings on "desktop" processors.  Toshiba's power utility also does not manage these settings very well, so your processor is always running near full power no matter if it's playing a video game or just editing a text document.  The RightMark utility automatically adjusts the processor's clock speed, operating voltage, and throttle according to how much speed you need at any given moment.
I am a Toshiba Laptop Tech. The A75 in notorious for over heating. The fins on the heat sink get clogged with link much like you clothes dryer. This restricts airflow which leads to overheating and ultimately the machine will shut itself down.

The Solution:
By some canned PC air and blow in into the fans from the bottom.

If you are feeling gutsy, disassemble the machine clean the fans, heat sink and apply the thermo-heat grease.
