Toshiba boots up power light stays on and shuts down, bad m/b ?

Three blinks in a row is the LED code for a memory issue.

Turn the laptop over, remove the panel over the RAM, remove the DIMMs (it will likely have 2 in it), place one in at a time and try powering the system on.


One of the two is likely bad although it is possible (although very unlikely) that both are bad. It should boot up when the good DIMM is in place. Once you have identified the bad one, buy a replacement or possible choose to upgrade the total amount of RAM.

It looks as if the LED code would indicate a memory issue. Three blinks in a row.

Shuts down when? Immediately when you start trying to boot it? And if nothing ever posts on the lcd screen your problem is either the memory or the video card most likely.

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 power cord?

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 it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Try this :

1. unplug the ac adapter and remove the battery .
2. press and hold power button for a minute
3. now put the battery back and plug in ac adapter
4. turn on the laptop now

it should work.

if not, try removing hard drive and memory modules then reinstall them back.

if the issue persists, your motherbord has gone bad.

Try this
unplug plug the power cord and remove the battery and hold the power button for 45 seconds,Then reinstall the battery and and try to start the computer,

if it fails to start
unplug plug the power cord and remove the battery and hold the power button for 45 seconds and
remove the memory and any usb devices that may be plugged in,then start it,

If it starts

Allow it to load completely and then shut it down and install one memory stick and restart, if all is well after if loads completely, shut down again and install the other memory stick and restart, if all is well again wait until it loads completely and then plug in and allow to load each of the usb devices you may have

If your charger is working properly and the laptop is as well, then the laptop should work without a battery in it at all. If your new battery worked and laptop worked with it until the battery died, then the charger or charge port is damaged.

If it does not work with charger plugged in without a battery, then your charger(s) or the laptop charge port itself may be damage or broken. Or worse, the laptop may be dead.

If the laptop does nothing even with a good battery with charge (no fans, no boot, nothing on-screen, no noises) you're laptop could be dead; likely a burned motherboard or processor. It may have overheated or something along those lines.

The Motherboard is bad but before you buy one.Try this Remove the memory, cd rom,hard drive battery, power adapter. Press and hold the power button down for about twenty .Replace the memory only,power up if you get the same result the motherboard has to be replace

Try also taking out the hard drive and the dvd drive to make sure that they aren't shorting out the motherboard.

Also try another stick of memory besides the one that came with your laptop to be sure the memory isn't bad.

If after you do these steps you still can't get video then your motherboard is bad.

Either the battery is faulty, or the charger is faulty.
Check the fuse in the mains plug, or even the power point you are using could have a bad connection.
Test using a lamp that you know works or a radio or something and try the charger in another outlet to find the fault.
