    Attention to the translator Google! (I from Russia) regards, expensive dose!

    I want to sincerely thank you for this work! You greatly helped me! In me certainly everything strangely remained, because in me Vostro 3300 xD. My BIOS was renovated to A12 in 2014 the year, then to me suddenly it was wanted to open some functions, and without you, my by road DoZe, I did not manage. Now, when you include instead of vostro 3300, written vostro 3700, I do not know, why xD I am specially registered in order to thank you! Again thanks!)))))

    Hi
    I've had trouble with my Vostro 3700. I flashed the bios (under windows- wish I had read this first) and bricked my laptop. Anyway, tried the recovery as suggested with USB but nothing happens - no lights on laptop or power button but fan starts up- screen is blank.
    I went through the process of buying a ch341a programmer and re-flashing the bios on to the chip which seemed to go ok but the laptop still powers up with no lights or no display. Any ideas what I might try next?

    Thanks for any help.

    Black screen recovery (walkthrough)

    Ok so I accidentally checked mxm support off in bios with non-hybrid graphics on.
    That resulted in a black screen with all else OK.

    So this is how you recover bios blind:

    Make the winery file and put it on usb described earlier in this thread.

    Then, remove battery.

    Put winery usb in usb port.

    Hold end while connecting charger cable. Hold end like 10 secs.

    So now the screen would have displayed continue with flash? But you need to mark it by pressing down arrow once, and then press enter.

    Now it flashes recovery so wait for it one minute.

    After it is done you wont notice, but if all is well when you press escape it will reboot with screen on!

    Short version :
    1. Battery out
    2. Winery usb in
    3. Hold end
    4. Charger cable in
    5. Release end after 10 secs
    6. Press down arrow on keyboard
    7. Press enter
    8. Wait 1 minute
    9. Press escape on keyboard

    Machine reboots and screen working. If this doesn't help my best guess is hardware failure.

    Hi.

    To use an eeprom Flasher , you need a Raw Dump or a RAW image of the bios file. This is why you obtain only a power up, but no light or boot.

    Did you try the Jimy jansson or procedure in post #15 ?
