Hey guys! I have asus X409UB rev 2.0 with no display, fan not spinning but the cpu is getting hot. Can someone have good bios on this kind of model. I also attached back up bios I extracted from bios chip.Comment

With ASUS, not everything is quite so simple. I will show you my way. It may be longer or harder but it is the right way to do it in my humble opinion.
For example, you can have 3 similar ASUS motherboards, all being the same model, all of which will have different BIOS versions.
I will give you an example and my version of preparing BIOS from ASUS website and in the process I am always cleaning Intel ME while doing it so you have fully cleaned BIOS, no DMI data, no password, nothing.
This is the picture of 3 similar ASUS motherboards, all of them being X555LD... -
Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hi there,
I know there is somebody who can tell me what is happening with my laptop. For start, it is an asus vivobook s510ua with an asustek x510ua motherboard with an intel i5 7200u cpu and 16gb ram.. i have a screenshot from speccy before strange things started.. as you can see the laptop type and bios version x510ua.302.I don’t manually update the bios because i don’t like to having a bricked bios, i know what troubles that gives..
I did a fresh win 11 install, and after the automatic updates, windows rebooted and automatically started asus ez flash..... -
Hi,
I have a serious problem to program the Z590 chipset SRAM with a Management Engine after replacing the chipset.
The new chipset is factory new and is not containing any Management Engine. Any attempts to program it into the chipset under Windows ends with a failure (eg. Error 20: Management Engine Device not present, or something similar).
Due to the lack of the ME several ports on the board, including all M.2 ports aren't working, booting OS works only on USB. So it's now other way, as to program the chipset with a ME.
Usually on ASUS boards it worked... -
Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows
