Toshiba Satellite A55 Series S1063

With battery or AC adaptor power my laptop will not turn on. It gives me a blinking coded yellow flashing light at the power cord icon in front of the laptop. I have tried to reseat the processor, memory, hard drive, etc.(nothing). I am wondering if its the power strip or connections on the mother board? Any suggestions would be greatly appriciated. Thanks, Aaron

    Thank you for this information, but my laptop wont even turn on to download any updated drivers. Again, my laptop is flashing a yellow light beside the power cord icon in front of my laptop. I believe it is flashing a code of 1 2 4 1. Dont know what it means. I have reseated hard drive, processor, memory, etc. No change, still flashing code. I have measured 15 v out on my charger, it is good. I have tried everything still getting flashing light, and nothing else beside the battery or the on/off icons. Any help would be appriciated, Thanks again, Aaron

The blinking power cord icon indicates that the battery is not charging, or is defective enough that it is overloading the charger. The laptop will not turn on unless it "thinks" the battery is charged enough to operate the computer. Even though you have the AC power connected and your adapter may be OK, it is still possible that:

  1. The power jack in the rear of the computer may be broken or otherwise defective, as well as the electrical connections to it.
  2. The wires and/or circuitry which connects from the power jack to the battery contacts may be defective.
  3. The battery itself may be defective.
  4. Can you operate the computer with only the battery?
  5. DON'T try to operate the computer with the battery removed, as this can lead to a situation where the internal power supplies receive too high an input voltage. This varies from model to model, but it is generally something to avoid, since there is not much detailed information available showing the circuits in detail, we cannot make a good "guess" as to whether this may be a problem. Best to be on the safe side.
  6. If you have checked the above items and have not learned anything new, AND, you have removed the battery and adapter, turned the computer off (not in that order, of course!), and let it sit overnight, and it still exhibits the same problem, that means you have "something wrong" inside the case which will require "major surgery". That is best done by a technician familiar with Toshiba laptops, and preferably, familiar with this particular model. He should also have access to proprietary Toshiba repair documentation and test procedures. I've learned from experience that it usually does more harm than good to "poke around" inside any computer if you don't know precisely what to look for, what to do, and how to repair problems you find. Unlike simpler electrical or mechanical devices of the past, you can't learn very much be observation and tinkering inside a computer! Too much is hidden from view, or depends on special parts which can't be fixed even if you determine they are defective; they must be replaced.
  7. This is about all you can do from outside the case. If you notice any other symptoms, no matter how isolated or trivial they may seem, please let me know and I will see if there is anything else I can recommend. Unlike desktops, laptops are not made to be easily repaired by replacing circuit boards, add-in accessories, etc. They are pretty much self-contained. Once you determine that the problem is inside the case, first you decide if the laptop is still worth enough to warrant the hundred-dollar-plus cost the repair is likely to require, or if it would be better to replace it with a new model, or look for a used one on eBay or some other place. This is not a conspiracy by Toshiba; it is just what is necessary to get everything into the small package and keep the price within reason.
Good luck!

My toshiba sattellite a55-s326 has a flashing yellow light but won't power up.


You may try this; Turn OFF the laptop, remove the power sources (ac adapter and battery). Without power sources, hold power button 10 secs. Put back the power sources, and power ON the NB. If the laptop will not boot by doing this, take it to the nearest repair center to have it check for possible motherboard issue.

Hope this works

Toshiba Satellite 1405 - Power problem

Hi Don

Although symptom is showing that AC Adaptor is not working as its not providing power to the unit. I will suggest you to perform some basic troubleshooting steps. Check if outlet is working if not check with known working outlet. If you have a multimeter you can the output of the AC adaptor.

Also you can perform full power cycle and component discharge. Take the battery out and disconnect the AC adaptor press the power button and hold about 7 seconds. After that put the AC adaptor in and test again.

If issue persist take to nearest Service center check with known working AC adaptor. After that I believe you will figure out the best solution.

Good Luck
