Question about Toshiba Satellite A75-S209 Notebook
I have tried new memory, removing the battery, and tested the charger, boots for about 8 seconds and shuts down. No display but does leave a line in the screen for about 10 seconds. The comp shuts down, fans turn off but the power light stays on. Could this be signs of a toshiba mother board
I own a Laptop Toshiba Satellite A75-S2131.
This series have a problem with the cooling flow to the processor.
The processor overheats and the laptop shuts down.To solve this particular problem you must tear down the laptop and clean up the processor heatsink (you will find it totally plugged or partially dirty).
Find in the internet the step by step instructions (with photos) for dismantling this laptop. Do not forget to apply thermal paste between processor & heatsink.
I hope this solution helps.

When you plug in the power cord is there any lights
whatsoever on the laptop, where the plug goes in or on the AC Adapter of the
When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).
Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button. And if that's true maybe you was operating off the battery the last time you had it on and since the power cord is bad, it was not charging the battery so the battery is drained and the power cord is bad.
Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove the Battery, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in (leave the battery out) and hit the power button to see if it boots. If it does, you can put the battery back in and let it charge.
Maybe your DC Power Jack which is where the power cord plugs
into the computer is bad. Take an ink pen and push the tip inside the
jack and see if the little pin wiggles, if so the jack is bad. You'll have to
take the laptop apart to fix it. Most times it is soldered onto the
motherboard, so you will have to desolder the old and solder a new one.
Maybe your memory is bad or the memory slot is bad.
Remove the Power Cord, Remove the Battery, Remove
the cover that houses the memory on the bottom of the laptop then remove
one of the
memory chips. Set the chip aside then try rebooting the computer.
If it boots, then you know the memory chip you set aside is bad so mark
an x on
it with an ink pen. If it fails to boot then move the chip to the next
memory slot and try rebooting. If it fails take the chip out and set it
aside, then put the other chip in and try booting it in both slots. If
boots, just to verify that the chip set aside is bad, mark an x on it
it into the open memory chip slot and try booting.
