ASUS M3401QA BIOS request

[kingblade20]

Hi,

My M3401QA does not power on properly: no display (all black) and with white LED charging port blinking slowly (once every ~3 seconds).
Checked several points across the board and supplies are up and running but I need to double check when I get schematic.
Result is still the same even with DC jack inserted and battery connector removed.

Tried flashing the latest BIOS as of this date to no avail which I suspect has something to do with DMI but tools could not run properly on my machine and couldn't find manual copy of DMI through hex editor and not sure about the addresses involved, sorry.
Please see attached zip for the BIOS dump before I flashed the latest manufacturer BIOS (*.bin).

Looking forward for some assistance if someone can provide the new BIOS with DMI and other information required I may not be aware of. thank you.

Cheers!

Hi All,

I tried downloading the ASUS EZ flash version 308 -> extract to binary -> remove addr 0x00000000 to addr 0x000007FF -> and copy address 0x00021000 to 0x00030FFF from M3401Q_Read_05172024.bin (which I assumed to be the DMI) over to the version 308 binary. I then flashed the modified version 308 but the laptop does not boot up still.
attaching the modified version 308.
Can anyone help where I might've gone wrong here? Thank you

Hi hoaca388,

I believe this is the default BIOS from Asus website EZ flash version without the 0x00000000 to addr 0x000007FF, correct? I've tried flashing but result is still the same.

Hi Luke11037 ,

Mine blinks at a very slow rate (few seconds white LED on, few seconds off, then repeat), so it's the latter in your description.
Could you share the boardview too? is it specific to M3401QA?
Quite unlucky I can't run openboardview on my two other machines so far.

Good day, my laptop's bios got corrupted after windows update. I tried reflashing it via Ezflash however, it worsened the problem and now it wont turn on. I search for fix in asus but wont work. i dont have the dump file. My laptop won't display anything and no fan when I press the power button. Can someone please share their BIOS BIN so I can reprogram mine. Thank you so much for the help.

Post a picture of the QR code on the motherboard, or scan it yourself and post the info.

i found this 2 QR codes in the motherboard. Not sure which one do you need.

The serial number in the QR code is MB47NBCX00V7HDMB ,different to the one you posted, so it`s either had a replacement motherboard or the base cover is from another laptop. Try the attached bios .
