    Hi there
    Nice forum, I have problem with my Dell Inspiron 1520 I was upgrading bios to A9 when the laptop just turn itself of, now when I press power all I get is the power, HDD lights come on disk drive works and the fan but nothing on the screen, laptop was working fine before this happened i.e screen and ram is not the problem, I guess the bios eeprom is blank since the flashing was started.
    I was reading through threads that relate to the problem I’m having and there were good ideas and instruction but the download link provided in this thread (Dell Phoenix Manual Mod Thread page 162) does not work, I was hoping for some help to get this modified bios for ispiron 1520 to get my laptop up and running again.


    Thank you for your help:biggrin:

    what bios version was it before u update/fail.? best is to use same version it had prior to failure.

    extract HDRfile from exe with command prompt .. drag and drop the bios exe to the cmd window then type

    1525_A0x.exe(space here!!!) -writehdrfile

    notice the x is the version number.. also remove the _ on the hdr for filename
    1525A09.hdr

    take memory sticks out from under laptop and make sure the contacts are clean.. use 1 (optional)

    place it in usb storage and plug in to right side not rear with battery and power out.. hold end and power button .. now plug in ac power and let go of keys after led is blinking pink.

    should turn itself off after 2 to 4 minutes.

    i found this overseas.

    1. If you are using Inspiron 1520, Inspiron 1525, Inspiron 6400, Latitude D410, Latitude D610, Latitude D620, Vostro 1400 or probably newer Phoenix bios.

    Please recovery your bios according to the followings:

    This is a method originally described by REDALERTHAN on the Mydigitallife forum an developed by by Dan. http://www.walms.co.uk/dell-bios-recovery-procedure/ .

    I am writing it here to make it more permanent and hopefully easier to find, I have already had to replace my motherboard in my laptop 2x thanks to failed bios updates, partially due to my impatience and experimentation. Most if not all DELL bioses on systems are based on the phoenix bios. The phoenix bios contains an emergency bootloader in case the actual bios becomes corrupt or the bios update fails.

    I have successfully used this method to recover 2x Vostro 1400 mainboards.

    1.) Firstly download from the DELLs website the latest version of your BIOS, for me this was 1400_A09.exe, then copy it to C: \

    2.) Open a Windows (MSDOS) command prompt, and type (replacing the name of my bios file with yours) 1400_a09.exe -writehdrfile Now you will find the file "1400_a09.hdr" @ C: \ on your PC.

    3.) You now need to copy this to a formatted USB stick (FAT / FAT16 / FAT32 to be confirmed), only this file. (Some models only accepted USB floppy drives) I found that a FAT formatted 128mb USB disk worked, my 2GB stick didnt seem to work. It also only seemed to work in the LEFT side USB ports but I couldn't be sure for other models.

    4) Remove the battery and the AC power cut the cord with.

    5) the Plug in the USB memory stick into one of the the USB the ports.

    6.) Whilst holding down the END the key the plug in the the AC adapter,

    7.) The battery light should come on, on the Vostro it came on purple (i suppose green and RED at the same time)

    8.) Then release the END key, the power light should come on and the laptop power up, wait a moment ensuring the power stays on, hopefully the USB stick will start to be read. The LEDs will start flashing different colours and the fans should be on loudly.

    Eventually the laptop should automatically restart itself. If all has gone well then the DELL logo should be displayed. The entire flashing process probably takes less than 30 seconds, it is very fast.

    Confirmed the models:

    Inspiron 1520 - Confirmed (06/05/2010) (File muse be renamed COR???. BIN or COR???. HDR ie COR123.BIN or COR123.HDR, (someone please confirm the exact name they used) (Thanks to Magro on the MDL forum for confirming this.)

    Inspiron 1525 - Confirmed (28/04/2010)

    Inspiron 6400 - Confirmed (28/04/2010) (Hold END until the power LED comes on then let go, flashing worked with memory stick in any port.)

    Latitude D410 - Confirmed (File must be named VENI???? BIN or VENI???? HDR, ie VENI1234.BIN or VENI1234.HDR)

    Latitude D610 - Confirmed (File must be named AZED????. BIN or AZED.HDR, ie AZED1234.BIN or AZED1234.HDR)

    The Latitude the D620 - Confirmed

    Vostro 1400 - Confirmed (27/04/2010)

    Actually, you can find the correct file name in the binary. Rom file by searching the characters "HDR" in Notepad.

    Hi, thank you for your help but I had no success, I have followed the instructions and tried all sort of things including removing the hard drive and disk drive so it can boot from the usb and I have tried 3 different usbs in all the usb ports with no luck only 1 usb light flashed once when I held the power and end buttons the other 2 usbs light did not flash at all, also I have made and ISO with the files you have provided and boot disk files and burnt them to cd/ dvd I though I’ll try that since my laptop was set to start from cd, I even tried to use external floppy but still no luck.
    But good news in the end after all that I got it working again thanks to you the hdr file was the correct file but the key combination was not, after a lot of reading as you have mentioned in your first reply plug in the usb and hold the END key only without holding the power key plug in the charger as soon as the battery light flash red let go of the END key and it should kick in to flashing the bios with no video and fan on full after a short period the laptop turned itself off and back on with bios updated to A09, it would not accept my other usb but accept my scandisk usb.
    Thank you for your help my laptop is up and running

    Hello Guys,

    I tried to flash as instructed on a inspiron 1520 however after the restart i get the same result as before the power light remains on and the screen remains black and no fan.
    Depending on the bios version some of them cause the pc to restart and other to turn off after flashing. Can you please advise. Appreciate your help on this.

    try a usb sd card adapter.
    check ram sticks... 1 at a time.
    plug in external monitor

    if external monitor works then lcd is broken.
    if none work.. it could be the nvidia reflow issue. ( youtube reflow nvidia)
