    Inspiron 7547, on Dell's site I saw there was a new bios A08, I had A05. Made the bootable dos usb and started the bios update, it wrote a bunch of stuff ok but then had an error msg 'P/W: Not enough memory'. Nothing changed after ~1hr so I had to power off.

    Now it won't boot. The power LED comes on, I hear the fan, but screen is blank, no Dell logo. I have tried taking out battery, pressing power button for 1min, didn't help. I also tried the method here - https://www.linkedin.com/pulse/solved-recover-dell-inspiron-laptop-corrupted-bios-how-roland-ihasz. Still nothing.

    This is a fairly new laptop but is out of warranty. I feel stupid for trying the bios update. Is there anything I can do? This was my main computer.

    • Shutdown your faulty laptop if is is still running with the black screen.
    • Remove the battery
    • Remove the CMOS battery
    • Disconnect the power supply.
    • Insert the USB drive with the extracted BIOS files in the USB port.
    *Note: There are few cases reported about not active USB ports. Simply try to use other USB port if you notice or suspect that the system cannot read the USB drive from the port you plugged it. Use USB drive with activity LED if you have one, the blinking LED will confirm that the system reads data from your USB drive.


    • Press and keep hold the END key on the keyboard for your faulty laptop.
    • Plug the DC power connectors (power plug) into the laptop.
    • After a few seconds your faulty laptop will start itself and will re-flash its corrupted BIOS and automatically reboot.
    • You can release the END key after the flashing process started. A USB drive with an activity LED can confirm that the BIOS flashing process started. The complete re-flashing process will take no longer than 60 maximum 90 seconds.

    Those are the exact same steps from the link I gave! Like I said that doesn't do anything.
