    Same problem here, actually. When I plug in the power cord, the indicator light on the front show green for the plug and orange for the battery. As soon as I hit power, though, all of the indicator lights fade away and I get bubkis - no lights, no power. I had changed out the front cover one day and I'm wondering if I accidentally short out the motherboard somehow... does anyone have any expertise on this? I'm totally lost.

    Hi everybody, I have a problem with a A45-S250 laptop in which I opened it up and when I tried to plug the AC cord no light would turn on. In normal cases a orange or green light would appear next to the battery image. What is the cause of the problem and what are the solution(s) to the problem thank you.

Hi,

Your concern (auto shutting down) with Toshiba could be caused by excessive power drain by some of the attached devices such as the WiFi, LAN among others. On the other hand, it could also indicate that the battery is already weak and constantly requires charging and at times eats up most of the power from the adapter leaving nothing for the motherboard to use. In some repairs I have done, switching off / or removing entirely unneeded devices correct the problem. In some instances, auto shut down is caused by dirty/clogged airducts/heatsink of the processor, failing blower/fan and/or poor ventilation.

Of course, it could not be ruled out that internal problem with the power supply/regulator to have caused the shut down. Alternately, there are some viruses and malwares that could trigger shutdowns.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

I removed the harddrive , turned off the wireless lan and even diconnected the video screen. Still nothing. Now have the motherboard out on the desk, and some very hot componets near Q503 on the motherboard near processor heat sink. To hot to touch, I wonder if this is normal?

When I push the power button to power the lap top up the light display that says outlet power changes from green to amber and the laptop will not power up.


try removing the battery and just use plug power only if it boots normally then change the battery and the change the power supply unit as well I would just start with the power supply unit first then see if the battery charges up if not the battery is bad replace it. Now if the computer will not start with the battery removed then you have a power supply issue.
Change and replace it. Hope this helps. Also when computer lap top get hot they will shut down to protect the computer wait and let it cool down then try to restart your computer. If this does work and the lap top restarts normally get a fan cooler that is USB powered and the lap top sits on top of it. Also make sure the fan is running and is not stopped. Clean and dust it out once in awhile. I hope this assists you with your problem. John

My toshiba laptop suddenly went into hibernation. I can't start it. What should I do?


mcdevito75 here, You can try to presss the shift key, also try to put your lap top on, with either AC wall power or battery. If this doesn"t work bring the lap top to a local Radio Shack, or Staples for help.

Toshiba Satellite M45-S331 willnot operate on


Hello,

You have replaced the battery and then it worked.
Try once with power draining (remove the battery and then press the power button for one minute and then again refix the battery) and check.

Thanks

Toshiba laptop power cable won't charge battery


I had the same problem with my HP laptop some years ago. you have a broken cable/cord and it is the part that is permanently attached with your power pack. If you look at the cord that plugs into your laptop, you can be able to see the faulty part of it. it is usually very flexible or swollen. You can either take it to an electrical technician to change that part of the cord. Your power pack is still ok, but have the technician to check it out first before you change the cord. Else, you may have to get another power pack. below is the full specification of the power pack that is recommended for your laptop.

Have the battery checked or better yet, replaced. Prolonged use might damage the charging circuitry of your machine.
