Satellite C855-1st wont even boot BIOS

Hi guys I really could do with some help.

I have a toshiba satellite c855-1st. I came to him today and it wouldn't start at all.
When I hit the power button I get a white light solid on the front but nothing happened.

I googled my problem and I tried all the "remove the battery, hold power 60 seconds, try new etc etc' advice, no plan for me.

So I decided to demolish everything and managed to get the system tries to boot (hdd light lights, fans spin, display lights etc.) but I just get a black screen for 30secs then it stops. Ive tried to remove the cmos battery, remove, Exchange and alternate the 2 ram sticks but still no joy.

When I put back it together but it goes back to just the white led (no fans etc.). I discovered that when I unplug the keyboard, then it will try to start but fail after 30secs. It does not seem to be still "ad".

I find the keyboard very strange thing and the only thing preventing me from believing that my motherboard is dead...

can someone please shed some light on this for me. Thank you

.. .but I just get a black screen for 30secs then it stops. Ive tried to remove the cmos battery, remove, Exchange and alternate 2 ram sticks but still no joy
.. .thing keeps me from believing that my motherboard is dead...

I'm afraid you might have reason... it's just my personal opinion, but if the laptop does not start using new, good work RAM modules, then the motherboard could be the troublemaker...

  • Satellite C855 - 21Q does not start - BIOS flash failed

    Hello.

    I'm french, sorry if my English is bad.

    I updated the Bios of a Toshiba C855 - 21Q. But during the flash, mobile restarts.

    Now, the computer will not boot (black screen + power on wifi led flashes).

    I'll try the recovery mode.

    I extracted the exe file. Rename the FD PLCSF8. EDM
    Copy to the root of the USB stick (256 MB FAT16).

    Can I plug it into the laptop with AC, HDD, unplug. Just the USB STICK.
    Plug the AC, hold + B key and start the computer.

    But nothing happens. The USB is not read (no Flash)...
    I also tried with the other key like Fn + F / Fn + B / Fn + Esc... still nothing.

    What are the keys to start the recovery.
    The process is correct?

    Thank you.

    Hello

    Unfortunately, you need special BIOS version to be able to Flash the BIOS to USB flash memory.

    The fact is that you could download only the version of the BIOS Win-based driver Toshiba UE page and requires this version of BIOS preinstalled system.

    In your case, it seems that something was wrong during the process of updating the BIOS and the EPROM module was not properly flashed. To resolve this problem, the EPROM module must be flashed once more use special disc of crisis of the BIOS.

    To my knowledge, this can be done by Toshiba approved maintainer.

    However, I have also read in this forum that only users managed reflash the BIOS with Bios Phoenix crisis recovery tool. Not very well where you can find these software but recommend to google.

  • Satellite C855 - 2 FG is not booting UEFI

    Hello world!

    I would ask that the laptop Toshiba Satellite C855-2 FG cannot start mode UEFI? Or he will be put in a new update of the BIOS?

    Before ask you, there no a favourable UEFI or secure boot option in the BIOS.

    Thanks for the replies!

    If the BIOS does not include UEFI or the secure boot option, then the changes are unnecessary.
    You should be able to start or install windows systems (Win 7, Win 8.1, etc.) without making any changes in the BIOS.

  • Satellite C855-1j4j does not turn on - the Bios Update interrupted

    Hello

    I did the update on my laptop Satellite C855-14 days, and all of a sudden the power went out,
    now the pc running either party but not nothing DON'T get PAST...

    What should do?

    + The message was edited: message has already been translated.

    From my point of few the EPROM module must be re-flashed once more with special BIOS crisis recovery disk.

    Usually, this procedure could be done only by authorized service provider available in your country.

    But I found an interesting announcement about how to flash the BIOS on U400 series.
    See the last post [here: http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=62852]

    But I don't very well if this info would be useful and if it would work in your laptop to Mr. However, in case this would not work, contact the ASP from Toshiba for help

    Hello

    Toshiba UE driver page provides only focused on the Win BIOS version.
    This means that the BIOS update can be run Windows System.

    But I found on Toshiba WE packages driver BIOS page containing both versions.
    http://support.Toshiba.com/drivers

    But the fact is that you will not find a European model of mobile on the Toshiba U.S. driver page.
    So in this case, you will need to find a Satellite C855 we model equivalent to the European model.

  • Satellite C855 - white screen after BIOS update

    Hello

    I am a beginner user,
    I have Satellite C855
    Yesterday, I downloaded a 'update BIOS"that was sent to my computer.
    Since that my screen is blank, there is a hum in the background.

    I have a recovery back up on my external hard drive, but of course, the screen is blank so I don't know how the product.

    I think I must have downloaded a model or the update was not compatible.

    Hello

    White screen do you mean that nothing appears on the screen?
    You see the start screen of Toshiba, or if you are able to access the BIOS?

    Where this is not possible, try this:
    Disconnect the power adapter, remove the battery.
    Press and hold the power button for about 30 seconds.
    Then connect the two parts (batteries and AC adapter) for the laptop and try to turn on the unit.

    In case this would not solve the problem of the laptop, I'm scared of m the BIOS update was not completed successfully and I think that only authorized Toshiba service provider would be able to help you.

  • Satellite C855 - 12K - BIOS password incorrect supervisor

    Hello

    I own a Toshiba Satellite C855 - 12K and there is a problem with the BIOS supervisor password. Once I put the password, I was unable to access BIOS because it says that the password is incorrect.
    I am positively sure that the password im putting in is that I put in the BIOS before because I have used the same password to lock my HDD to 100%.

    Somewhere online I read that this BIOS version has a bug that makes it unable to remember the password.
    Is there any solution to this or I have to send my laptop for Toshiba?
    Operating system is windows 7 Professional-

    Unfortunately there is no magic solution. I can't comment on speculation on bug BIOS but if there is a problem with the service provider Toshiba BIOS must be informed about this.

    I recommend you contact the nearest Toshiba authorized service provider and ask for help. They can remove your password.

    This password protection is very serious characteristic safety and public forum is not the best place to write about the ways how it can be removed.

  • Satellite C855-12Z - strange noise, even if the cooler is off

    Hello again,

    I have a toshiba satellite c855 12z and I heard a strange noise even if toshiba pc health monitor shows that the heater is off, it's like an air blowing inside the laptop, you need 2 coolers? or can it be the hard drive? When I bought the laptop was very quiet, now I always hear this noise...

    Help please

    It's always hard to talk about things that are not verified...
    There are two things that could create a noise: cooling fans or HARD drive.
    Cooling fans are not DISABLED the cooling module can run at a lower speed, but it is not completely off.

    HARD drive runs too, but it should not create noise if the HARD drive is OK
