Satellite C850D 11(f) does not illuminate

Hey there all,

I recently received a defective C850D Satellite of a friend hoping that I could work my magic, basically, the laptop fuel not on.

I tried 3 Chargers, I ve stripped to the bare bones unit and run a multimeter on the Board, there is power to everything apart from the exit of the fan, I am a little confused, it's just a bad connection or something more serious. I know it's not water damage and there is no visual damage to the Board or to the housing...

Any help would be appreciated.

Thank you very much

As I see that you have removed all laptop and make Visual and technical check.

On this virtual path, it is not easy to say with certainty what can be the problem.
Are there other symptoms?

I mean what happens when you connect to AC power for laptop?
Is DC led on? What is with battery LED?
There are some LED flashing?

What happens when you press the button walk / stop? Is there a reaction?

It is not easy to help, but if the phone is completely dead I assume electronic power supply may be faulty?

  • Satellite Pro P300-156 does not illuminate

    I've had this laptop for 2 years, it was working fine this morning and I pressed the power button to turn on the sleep mode. I went back to the laptop a few hours later to turn it back on and the power light lit for about 2-3 seconds, then came out and nothing happened. Whenever I press the power button, the same thing happens, the light appears for 2-3 seconds then turns off and the laptop does not start. This produces both with the power adapter connected and disconnected. When the power connector is plugged the adapter power light and battery light comes on.

    Does anyone have any idea can be what the problem is or if it can be fixed?

    Thank you

    Disconnect the power and remove the battery. Leave it for a while and try to start the laptop with AC power only.
    Please let us know what exactly happens when you try to turn on your laptop.

  • Satellite C850D-107 - screen does not work

    Hi, my first post here and need help please.

    I have the laptop above and last week I had 3 dead crushed inside my screen bugs, so I searched google and found some info on how to clean them.
    I took the screen and then carefully carried the front end, giving me access to the rear led? I cleaned the bugs and as I thought carefully back together, when I started the laptop backlight as does not I had thought broke I bought another exactly the same thing and put in, but its doing the same thing.

    The screen works but no light, so, any help would be great. I know there is no converter in these so what could the problem perhaps, cable the screen? I can't help LOL.

    Thank you, Wayne.

    > The screen works but no light
    I guess the backlight module does not work. Now quite sure if you get a defective screen or perhaps display isn't compatible/certified for this unit but the fact is that the LED backlight are simply connected with a LED backlight cable and there is no other modules which would impact on the functionality.

    So I think that you should simply try another display unit

    Hello

    On this virtual path, it is not possible to provide an accurate diagnosis. All you can do is to unplug the power plug, remove the battery and leave it for a while. Then press the power button and hold it for 15 or 20 seconds.
    After doing this connect the power running and try to start again.

    What happens when you do this?

    My satellite M30X 127 does not illuminate. When I push the power button, it is DIRECTED in turn. But nothing comes on the screen. There is no sound and the fan does not start. I took it to a repair center and they told me the motherboard is fried and it will cost me 400 pounds to fix.

    Sometimes people sell books with the failure to display or other parts of damage, but the motherboard is ok.

  • Satellite A300D does not illuminate

    Toshiba Satellite A300D does not illuminate

    The battery light is red when it is plugged in with the light of the white plug

    When I press the power button it lights up two other fires, and one that looks like a sheet a4 fact paper.it a vibration when turning it on also.

    Any help would be greatly appreciated

    Disconnect the power adapter and remove the battery.
    Leave the laptop unplugged and then hold down power button / stop along 30 sec.
    Then reconnect the two parts and check how the unit works.

    In which case nothing would be visible on the screen, try replacing the RAM modules. Perhaps one of the modules is the troublemaker
    Otherwise if the RAM modules are OK, the problem could be linked to the motherboard.

  • Satellite M100 does not illuminate unless the AC adapter is pluged

    I am also having the same problem with my Satellite M100. The computer does not illuminate unless the AC adapter is pluged and plugged into the power outlet.

    Any ideas on how to solve this problem? The battery should be fine.

    B.

    Hello

    Well, to me it sounds like a battery problem
    Why you say that the battery must be good?
    Have you checked it or because the technician?

    In most cases if the battery is faulty then the laptop would have no power until it would be connected to the power adapter.

    So I think (but that's just my personal opinion) the battery must be enabled (by technician, ASP) and if necessary should be replaced.

    See you soon

    You can always update your firmware with iTunes. But it seems you might have a larger, likely hardware problem with your phone.

    Try to restore the firmware with iTunes. If this does not help, make an appointment with a genius at the Apple Store.
