Satellite A100-749 does not illuminate

Hello

Since a few days, I have a problem with the power of the laptop.
Immediately after the connection of the AC adapter or the battery, it will not power upward.
The flashes of button and power indicator, any indicator on the keyboard flashes one time but the laptop does not work (hard drive and fans also).

I noticed that I have to wait a few minutes with is plugged or (I'm not sure) inserted battery.
Then, the portable lights and works normally on battery and adapter separately and jointly.
This means that the battery and AC adapter are not damaged.

I also noticed that, until the problem was the power LED flashes a few seconds after plugging in the power adapter. Similarly, the light blinks a few seconds after firing on the AC adapter.
I guess there is a capacitor that needs to be loaded.

When I can not turn on the laptop, this indicator will start / stop flashing immediately after plugging in / pulling on the power adapter.

Where could be a problem?
Could this be a problem with the CMOS battery that needs to be replaced?
Could this be a problem with a capacitor inside the laptop in the power circuit?
Something else?

Thanks to advice
Best regards

Hi mate

Usually the DC-IN (first on left) indicator lights up blue when the power adapter is connected and if the power supply is not assured. IF the adapter voltage is abnormal or if power failures then this indicator flashes orange.

((Deuxième à gauche), the power led lights up blue when the computer is turned on. If the laptop is in stand by mode indicator flashes orange, while the computer shuts down.

I think you mean the first LED and in this case, it seems that there is something wrong with the power supply electric or electronic.

  • Satellite A100-383 does not - the battery is not

    Hi all

    I own a satellite A100-383 (PSAARE) that does not start when the battery is totally empty, or if I leave without the battery of the day to the next. The battery will charge not façade is and all the lights are off. I should always have a load on my battery and don't let not unplugged more than 2 days.

    If for some reason, my battery was completely empty, Plug and unplug the power supply from the wall outlet would make all the lights increase and charge the battery again.

    Unfortunately, I went on vacation and I forgot my pc unplugged and it does not charge or turn on. ? The headlights are off. Tried my dear old method to connect the unit several times with battery and without it with no luck... I could see a connection for a second or two, but I wasn't fast enough to plug in and they are off.

    I would be so grateful to you all if you give me a help to put it on my pc. Once I have it on the load and back I'll buy a new battery for sure.

    I look forward to reading your advice.

    Thank you all in advance!

  • BT sending between Nokia 7373 and Satellite A100-207 does not work

    Hi everyone, I wonder if you could help me please.

    I have a laptop Satellite A100-207 with Windows XP Im trying to send a few things from my nokia 7373 to my computer and some stuff from my computer to my phone, but it won't work.

    I have the bluetooth Wizard thing on my computer, but it keeps telling me that it cannot find not all devices.
    My bluetooth is on and shown at all, so I don't know what im doing wrong.

    Do I have to download stuff?
    This computer no bluetooth in there?

    IM so confused so if you have ideas, please let me know.
    Ive tried to fix this for two days now and im starting to lose my patience.

    > This computer no Bluetooth in there?
    Your assumption is correct.

    This laptop does not support the BT module and so you cannot use it ;)
    If you can't find any BT label at the bottom of the unit and then the BT module has not been installed.

  • Satellite A100 PSAA9C does not work without the battery inside

    I'm having a strange problem with a laptop Satellite A100 (PSAA9C-SK900E).

    The machine will not work without the battery in it. If the power supply is connected in the machine and the wall, it will power without the battery installed. If I install the battery, let it load completely (battery LED goes from orange to blue and the plug LED is blue) then start the machine it will work for a period of time (more than an hour depending on what I'm doing) then suddenly turns off.

    If I restart the machine, it will work for a very short period (sometimes only for a few minutes) just before going off.

    If I do this a couple times, the machine will be not even by post before turning off.
    If I let the machine to recharge, it runs for a while and then do the same thing after using it for a while.
    If the battery is pooched, which is fine with me. How to operate with only the power supply of the machine?

    As I type this I'm suspecting that the adapter cannot be taken out the required voltage/amperage. (adapter is not still hot when charging, are my other laptops) Any suggestions would be greatly appreciated.

    Thank you.

    Hello

    If I understand your assignment, the laptop does not power up without the battery
    But it will light if the battery is connected.

    The question is; Is the power led on if the AC adapter is plugged?
    If this isn't the case, then it means that the power adapter is faulty and so the laptop cannot be turned on by using only the AC adapter.

    I think you should test a new adapter. Maybe it helps!

  • Re: Satellite A100-011 does not start, a black screen at the beginning

    I have a Toshiba Satellite A100-011, which is almost 5-6 years. It suddenly started to behave abnormal.

    First of all, I started to get a 1-2 sec black screen when he was running. The screen was on and off occasionally.

    After a few days, I could not started upward from my windows xp sp3 operating system. I tried to start in safe mode with networking to see if I had a few spy, virus or something. I ran avast, hijact, ad-aware and some more, but not found anything.

    Later, I tried to format my laptop with a xp professional, but this time I can't see any reflection that passes more fun running and a black screen. I just got a black screen at the beginning and it does not start.

    I plugged on a television screen, and here I have started. I have re-installed all the drivers and formatted, but all I get is a black screen on my laptop at the beginning.

    What should I do now? Do you think I have a problem with my screen of HW or a driver problem with nvidia geforce go 7600? Maybe I'm missing something?

    Thanks in advance for all replies.

    If you can see the picture on the TV there are a few s laptop display problem. Y at - it some problem connection or display itself.

    You want to fix it yourself? You can disassemble the laptop?
    I mean if you have any experience with this kind of things that you should seek professional help.

  • Satellite A100-232 does not start windows, but is stuck

    Hello

    I am having a serious problem with my old laptop (Toshiba Satellite A100).
    When I turn on the pc, it does not start the Windows but is stuck.
    If I press F2 to open the Bios, it seems not work while the works of F12 (select boot device), but it is impossible to start anything.

    I tried the following:

    1 removed, cleaned and replaced the RAM
    2. HARD drive removed and reconnected.
    3. check the HARD drive if it is damaged, but it is not.
    4A tried to boot from the Windows XP cd and install it but it crashes
    5A tried to boot from the cd with Linux, but it does not work.
    6. has created a Windows 98 flash drive to start, but it does not work.
    7 tried to clear CMOS by removing the battery, but I couldn't because he is stuck on MB.

    I visited a technisian but he couldn't fix it.
    He told me that the BIOS is corrupted or crashed. Maybe I should replace somehow.

    Is this possible?
    How?

    Thank you

  • Satellite A100-590 does not fuel upward, that a single LED works

    Hello Toshiba-Crew,

    first of all I want to say sorry if you don't understand some parts of my text, but my English isn't the best more :(

    As explained in the topic I have a Satellite A100-590. I got it as a gift from my father-in-law after the A100-590 no longer works and he bought another new laptop because the customer terrible service from Toshiba.
    As much as I want to try if someone of you can help me.

    Now to point to the problem of my A100-590.
    It worked very well for my father-in-law for about a year. Then all of a sudden it no longer turns.

    The only thing that happens is the power led (the one in the middle of the five) flashes, when the power cord is connected and the power button is pressed. This light flashes 10 times and that's all that happens.
    It flashes only when the power cord is not plugged in, if only the battery is put in.

    I mention that the battery is totally empty, because the Satellite has not been used for about a year and a half now.
    The A100-590 was sent to Toshiba already, but the only thing Toshiba has done has been to send everything back one put a paper in that the motherboard needs to be changed and it would cost around 650.

    I think they don't even look at the satellite, I know that from my other computer laptop manufacturer too.
    It seems as if changing the motherboard is the best way to repair a laptop. FS said it too, but it was only one my card WIFI which was broken.

    Maybe someone of you had an idea of what might be wrong with the Satellite?
    I think this isn't a big thing, but does not fit my technical knowledge of the laptop.

    Kind regards
    Basti

    First you need to isolate the problem to the motherboard.

    Try to swap the memory modules around and try to start with a single Module, try the other location.

    If you can access the Wifi card, remove and see if it boots.

    If it still fails, then its likely to be a faulty motherboard or video card if the laptop has a.

  • Satellite A100: Battery does not charge

    I have a problem with the battery of high capacity on the Satellite A100-720. Accidentally I forgot the action of critical battery set to 'No action', so the battery got virtually completely discharged and now the laptop refuses to charge the battery. The orange light comes on, but the NHC program reports no load current and just on 0%.
    It is also strange that if I stop the laptop and unplug the power cable and then reinsert, it takes a second or two for the connector blue AC light upward and another a few seconds for the battery charging light illuminates... that's not happened before.

    Is there a way to fix this?

    Hello

    While the laptop is turned on and connected to the adapter try to remove the battery and put it back up shortly after. Look at what happens and we report.

    By the way: what is the number of the part of this battery high capacity you use with your Satellite A100?

  • Satellite Pro M40X does not ILLUMINATE

    Hi. -.

    I have a M40X Pro Satellite that I bought 4 years ago. It works well until a few weeks ago.

    I tried to turn it on but nothing happen, nothing, no lights, no sound at all, completely dead.

    It is connected to the power supply and the power light is on, (the battery light does not work since there is a lot of time). I tried to remove the battery, unplug the power cable and after several hours or even days, try to turn it on and I got the same behavior.

    Only power if it is (the power light when you connect the AC power) but when I press the button "turn on" the laptop, nothing happens.

    My laptop isn't under warranty, so if someone could help find a solution that would be great!

    Thank you

    Hello

    I have read your problem related to the failure of hardware. It seems that the motherboard is dead, no doubt, the southbridge. In any case, you should contact the service center:

    http://EU.computers.Toshiba-Europe.com/innovation/generic/ASP_SUPPORT/

    Note that the motherboard is one of the most expensive parts of the tower and don't know if it's worthy to replace, it is better to buy a used or a new laptop.

  • Satellite Pro A60 does not illuminate

    When I try to boot my Toshiba Satellite Pro A60, seems to be powered. A few seconds later, there is a click and it cuts.

    I tried to turn on the computer with just the power supply with the battery removed, just with no power supply and battery and power, but none of these options are making a difference.

    I also tried to clean the fan in the aspirant from the outside by a suction pipe, but even once, it did not help.
    Can help you with the Please this problem?
    Thank you.

    Hello

    Turn the laptop over and unscrew the cover on the ram. Then remove the ram and try to turn it on again. If it lights, put the piston inside the laptop and try again. It does not turn on? Then your ram is dead. If yes then you can replace, or have your asp replace it. If this does not resolve the problem, there is a small plastic cover that runs along the keyboard just above the keyboard. Take this off and then unscrew the fixing screws to the bottom of the keyboard. Under the keyboard, you may have a second RAM slot. If Yes, try to remove the RAM stick and turn. It work? If this isn't the case, you probably have a problem with the motherboard. If it lights fine, then you have found the issue and can replace or continue using it without the extra RAM. Hope this helps and have a nice day.

  • Satellite Pro L300 does not illuminate

    Hi all, I'm new to this forum.

    I have a Toshiba Satellite Pro L300 and I've had it for about 2 years.
    But yesterday I closed the laptop as usual. But later I went back to it and tried to turn it on. But it does not work. Instead, when I press the power button the LED next to the battery symbol flashes orange/orange 6 times and then turns off.

    Can someone tell me what it is? I tried to let it load, but that has not worked. The amber light is the only light that flashes. It does not recognize that I plugged in the charger and I don't think that the battery was flat. So I'm angry and helpless right now.

    Can someone help me please?

    See you soon.

    Hello

    There are several indicators;
    DC, while running, the main battery, LED HDD/ODD.
    So I guess the power LED flashes in orange. Right?
    This means that something was wrong on the motherboard.
    Maybe power supply electronic malfunctions

    In this case, there is no much to do only mobo replacement could help to...
