    Asus N55SL total dead after BIOS flash

    Hi everyone,

    I have an Asus N55SL that crashed during a BIOS flash in Windows, and now it is dead to the world.

    I have repaired a few laptops that have experienced this using BIOS recovery methods that can be accessed by a certain key combination when plugging the power socket in.

    However these have required the laptop to still actually turn on, show any sign of life with a fan spinning etc.. but this laptop does nothing anymore. No fans, no lights, no sounds, not even a charging light to indicate the battery is chairing when the AC is plugged in.

    The key combination for BIOS recovery on this machine is apparently CTRL + HOME, but absolutely no signs of life from this machine.

    Can anyone please recommend something? Nothing else had happened to the machine other than a failed BIOS flash.

    Kind Regards,
    Graham

    only solution is to take out the spi flash chip and use a programer to program it, or buy a preprogramed chip.

        u will need a programing tool for it and a software. and also the bios file
        good luck.
        I have attached bios (spi) chip location and the bios file

          Wow thank you very much! Do you know what model the chip is? Someone at my work has a programming tool and programs lots of eeprom chips, would the same software be okay?

          For the bios file does it just require the .204 file or does something need to be extracted?

          Kind Regards,

            That chip is Winbond 25032BVSIG, my friend at work said he would need to know the exact method to flash a BIOS to it

              your chip is W25Q32BVSIG and the .206 is the bios software u need but ask your friend what type of programing tool he has and if that tool supports spi programing .
              i am using a willem programer for this type of chips from https://www.sivava.com

              the chip must be taken off from board and attached to the programing tool on 25cxx , start the software ,select the chip type you have, open the bios file in programing software, erase the chip and then write new software.

                SPI flashes can also be written with a simple parallel port adapter, if you have a computer around that still has that port.

                  Thanks for all your help, my friend said he hasn't got anything that can program SPI chips, I guess there is not much I can do then.

                    get your notebook to a repair shop and give him the bios file to write it to chip

                      I was hoping for an cheaper solution. I found someone selling an N55SL BIOS chip in America, maybe this will work..

                        If you ask them nicely, they will do it for cheap. I got one done for free.

                          do you got the chip out? or you need to desolder it to?
                          Just cook it! It's already broken.

                            It is still soldered in but I can easily get it off and replace it.

                              Before I order a new chip can someone please just confirm this is definitely the problem? As I said in the first post, I find it strange that it is absolutely dead, it will not even show a charging light when the AC is plugged in, no lights no sounds no fan.. could not be more dead!

                                There is main BIOS and EC BIOS. Some laptops have them in separate chips, on others it's in the same chip.

                                The EC controls all the buttons and LEDs and whatnot, so if the EC BIOS is corrupted, the laptop will be completely dead, yes.

                                    Hi again,

                                    Just an update - I sent the BIOS chip to a very kind person who flashed it for me using the file you uploaded (N55SLF1204.zip), I go the chip back and amazingly the laptop now did turn on, unfortunately the laptop did not do much else. The fan instantly spun on full speed and nothing was displayed on the screen, after a while the laptop turned off. After several attempts turning it on it slipped back in to absolutely dead mode, no lights, not even charging etc.

                                    I checked the ASUS website and the BIOS file they have available is "N55SLAS204.zip" for the N55SL, which is not the same you gave me. Is the one you uploaded for a different machine/motherboard?

                                    The chip has been removed again and sent again to be flashed with N55SLAS204, I will receive it back sometime next week. I just wanted to know now if flashing with the file you suggested caused the further problems, or if it should work but there is something else wrong..

                                    Regards
                                    Graham

                                      unfortunately the bios file is not exactly for your motherboard and I don't have other bios file available , but i will still search a full dump for you.

                                      the file from asus website is only ~2.6mb and is only an update to your bios. it will not work.
                                      You need the full 4mb file.
                                      Please post some details of your laptop : full model from back , cpu type , video (onboard,dedicated and type (nvidia,ati)) , chipset model , the exact name from mainboard.

                                        Thank you, the sticker on the back says

                                        MODEL: N55S
                                        MB Ver: N55SL ID:1C
                                        N55SL-S2019V

                                        Both CPU and GPU are changeable, the GPU is on a separate card, but my current processor is Core i7-2670QM and GPU is nVidia GeForce GT 635M w/ 2GB dedicated RAM.

                                        I do not have the motherboard, I left it at work, but I could not see a MFN number on it. all it said was N55SF Rev 2.0.

                                        I checked N55SF, it is the same laptop but different CPU/GPU. N55SF and N55SL share identical motherboard, which is just called N55SF Rev 2.0.

                                        Hope this helps!
