    Asus n70sv

    Hello guys!
    Today I "killed" my friend's Asus n70sv notebook ... we tried a SLIC 2.1 Bios for Win7.
    After pressing the power button the screens remains black and you can hear the DVD drive spinning up. Then the notebook shuts down.

    We tried burning the bios file on CD and USB flash drive (8GB), but you can only hear the cd spinning up and then power goes off. Also an USB flash drive formatted with the HP Tool didn't work.

    I have a Gateway JM30. I bricked it. When it boots up all the lights come on a few seconds and then it goes off. I have bought a usb floppy but I can't get it to access the floppy. I have tried ctrl + home, win + b, win + r, still nothing. Can anyone help me?

    Thank you! We're going to try this solution tomorrow.
    I can't believe I killed the bios completely because the DVD drive spins up/try's to read data and then power goes off.

    Probably the BIOS filename is wrong. How did you figured out the BIOS filename for the recovery mode?

    I tried fn+Esc and it still comes on for a few seconds and turns off. I know there has to be a way since it is not completely dead.

    Lenovo T61 bad BIOS flash recovery.

    Unfortunately the recovery procedure is not "software" based one but for sure there is elegant way to fix Lenovo T61. The "Lenovo solution" to replace the system board is the most stupid idea (at least for me). After unsuccessful BIOS update of my T61 it was "bricked". I couldn't succeed to start the Phoenix CRISIS DISK, with almost all the possible key combinations. Then I decided that it is time to fix it using "my" method.

    Deppending of security setting for the BIOS you have 2 options:

    1. If the BIOS password hasn't been set before the "bad" flash you need just to re-program / or replace the BIOS chip (Macronix MX25L3205D - 32MB). The bad news is that you have to completely dismantle the laptop in order to get the main bord out and to have access to the EEPROM (the chip is situated above the sodimm memory slots). The easy way is to order pre-programed BIOS chip (on e-bay) and just to replace the "bad flashed" one. Of course it is necessary to de-solder / solder again the EEPROM chip. You can also build up your own programmer using the PC parallel port (ask google how) where you can do the job without de-soldering. The other option is to buy some simple programmer, capable to support the EEPROM chip (NANO programmer as example).

    Remark: The replacement of the EEPROM and the re-programming are working on 100% (tested personally from me :D).

    2. If the BIOS password has been set before the "bad" flash then the re-programming or replacement of the BIOS chip (Macronix MX25L3205D - 32MB) will not be enough. If the notebook has a bios password set inside, replacement of the bios chip will result in an "error" message of bios password check and will prevents the notebook from booting. The password is stored within special password chip PCA24S08 which is located on the bottom side of the main board. The solution in this case is to replace both the "BIOS chip" and the "BIOS password chip". You can also re-program the BIOS chip and to replace the BIOS password chip with new one without password set (unlocked).

    I forgot to mention that after BIOS chip replacement you will find your MAC address with only F's. You have to look for tool called eeupdate.exe in order to re-program the EEPROM with your MAC address. For T61 the working version was 5.03.

    If somebody needs pictures of the exact chips locations I can provide some. Please PM me.
