FX553VE-DM318T(FX553v) not POSTING

[claws77]

My SSD is fine, my laptop motherboard is also fine.
I checked with 500 GB WD SSD , my motherboard boots into bios just fine.

I think my motherboard is either not able to provide enough power to my 1000 GB Orico SSD or my motherboard does not support such high capacity.

Anyways good news

May be an unsolved BIOS bug then, if you have another M.2 NVMe SSD you can try, preferably an older one PCIe Gen 3
If you can boot to Windows normally, but not enter BIOS setup with the current SSD, but removing it allows the system to boot, i don't know what could cause this behavior as i saw posts from people who claimed to upgrade with NVMe drives without issues here:
https://www.myfixguide.com/asus-rog-...grade-options/

Also if you can source an M.2 SATA SSD you can try that one too,

[claws77]

I have used my ssd to read and write, and also checked for bad sectors on the same laptop, from booting to windows. All test passed.

I suspect my motherboard can only support 128 gb ssd, because the only place i have issue is bios.

And my bios/motherboard cannot handle such high capacity causing issues.

today i will def. check my laptop, after work though.
see ya!

I think i have figured it out.
its my ssd.
If i remove my ssd, my bios boots up fine.

But my ssd is new.
Orion o700, 1 tb

How to verify if my ssd is faulty, or port or a compatibility issue?

Only way to test if SSD is faulty, is to test it on another PC if it causes the same issue
As PCIe Gen 4 SSD should be backwards compatible with PCIe Gen 3 host, like your laptop, it will be limited to Gen 3 speeds (max 3200MB/s) so there's no point spending more on a Gen 4 SSD, unless you plan to reuse it later on a newer PC
Amazon reviews from the link you posted say that it runs hot, assuming it draws more power than a Gen 3 SSD

I'm assuming the BIOS detects properly the SATA HDD, and you can access its contents from a live USB

Measure resistance across B5301, it should be 0 ohm, it connects 3.3V to the M.2 connector, your board either has that part installed, or it has a solder blob across JP5101
If B5301 is faulty, you can close JP5101 with a solder blob
If instead of B5301 you have a solder blob at JP5101, ignore what i said

Replaced my bios ic sucessfully.
from w25Q64 to 25L64.

My system still freezes when i press esc key to interrupt boot sequence. (To get into bios)

i.e. gets stuck at asus splash screen.

If i try get into bios using advanced startup options.
My pc still freezes but on a blank black display after asus splash screen.

I came across this https://www.youtube.com/watch?v=P0YzSWBm-TQ
but since i only have one display, i donot know how this applies.

Sometimes(after i have not used my pc for some time) my pc will have issues with posting.
I have noticed that my cpu and my chipset will get hot.
So i wait for them to cool off and then try starting again, it works.

When my pc starts and run smoothly this heating is absent.

[m1ch43lzm]

Opening the BIOS in UEFITool - Descriptor region says this:
Flash chips in VSCC table:

C22017 (Macronix MX25L64)
EF4017 (Winbond W25Q64)
EF6017 (Winbond W25Q64)
C84017 (GigaDevice GD25x64)
20BA17 (Micron N25Q064)

Either one is compatible, if the other chip you have is actually MX25L6473F it looks like it's compatible, according to the datasheet for that chip the device ID is C2 20 17, which is in that list

[claws77]

Does it have to be exact same bios chip?
i have mx25c6473f from a desktop motherboard.
Both are 64 mb.🤷♂️

This will be my segue into owning a hot air rework station.

[m1ch43lzm]

Voltage in pin 8 of the BIOS is OK, I can't think of anything else except a failing BIOS chip (W25Q64FV)
You'll need a hot air station to replace it, if you don't have the tools/skills best to take it to a repair shop explaining the issue (can't enter BIOS setup/boot menu)
You have a known working BIOS dump from SMDflea, it has to be flashed onto a new chip and soldered on the motherboard

[claws77]

Coin cell battery [C] =2.9 V
battery [B] = 50%
AC [A] = 19V

The output at pin 8 of bios chip after plugging each powersource and their combinations in order - first coin cell, then battery then ac.

See image.

resistance across r2802 and r2804 is 0.8, 0.6 ohms.
leads resistance 0.6 ohms.

Sorry it took quite a time to respond, job stuff.

[m1ch43lzm]

Now I'm beginning to think it's a hardware issue, with the 3.3v supply to the BIOS chip, the 5v supply, or a faulty flash chip, and the BIOS corruption/not going into BIOS setup is a side effect of that
As you said on the bios request thread it boots now into Windows but can't enter setup/change boot order anymore

You'll need a multimeter with sharp probes
Measure resistance across both R2802 and R2804, should be 0 ohms (same as touching the probes together), the schematics and board view linked above in post #27 will help to locate those parts

Also measure the voltage on pin 8 on the BIOS chip, should be 3.3v

i messed up, i reflashed the bios given by SMDFlea after reinstalling (fresh) windows, now its stuck at Asus logo, cannot go into windows or bios, 🤣🤣
i looked it up - google response boot order issues, but i cannot do anything

[claws77]

I donot think the linux usb broke my bios.
windows installer USB(or any other usb) worked once(won't work again) only because it was the olny boot option available for my bios to boot into, now it won't as i have installed windows.

Since i cannot access bios, the the bios will keep using the default i.e. my windows on ssd.

Yes secure boot is/was disabled for sure.

Yeah, you guys are a laptop saver.

[m1ch43lzm]

So the windows installer USB works now? And your Linux boot USB broke the BIOS again? Weird things happen... May be a BIOS bug that never got fixed by ASUS

Can be also related to this other bug, on a different ASUS laptop: https://www.badcaps.net/forum/troubl...iable-bios-fix

At least your laptop works 😁, and you have a way to recover it with the BIOS from SMDflea, next time try disabling Secure Boot in BIOS before booting anything from USB

[claws77]

Thank you!! Sephir0th m1ch43lzm It worked With conditions.

So as mentioned i needed to shift data between drives and install fresh windows on ssd.

After flashing the bios, the bios worked ok, i was able to boot into my live usb by selecting from boot menu.
After booting,
i just format my old windows partition.
Shift data around. Etc. (Now without the live usb i donot have any bootable drive, in my pc)

Since then, i was unable to acess the boot menu again.😥
I was still able to boot into windows installer usb because it was the only boot option.

Now i cannot get into bios or boot menu, again. 😥

i got lucky.

I would like to explore and solve this issue.

[m1ch43lzm]

I found my old CH341A and a compatible flash chip (same size, different model/brand) from a dead board to test
On AsProgrammer, after you press Read ID, follow the steps in this order:
1. Erase the chip (button with X)
2. Write the new BIOS posted by SMDFlea (link is working now)
3. Press the Verify button (the one with the = symbol)

[m1ch43lzm]

Try the BIOS posted by SMDFlea https://www.badcaps.net/forum/troubl...e5#post3658543

Database error on the bios request forum for now

After flashing the bios "https://www.badcaps.net/filedata/fetch?id=3658240" i tried to do my first boot. ik, it takes time so i waited 30 mins
it got stuck at asus logo.
so i went back and shorted my cmos battery pins.
removed everything except keyboard, keyboard backlight, lcd, ac adapter.

the bios lit up. in 15 secs
so i went back AGAIN and inserted each cable one by one.
i narrowed it down to my trackpad.

so without only my trackpad connected
i booted into windows only to get boot device failure. -- i suspect this is because of the secureboot variables (idk for sure)
since i do want a clean install, boot device failure means nothing

i tried to boot up my live puppy llinux usb -- again stuck at asus logo, cannot enter bios as well.

so i thought maybe its the 5v rail. cuz trackpad uses 5v and usb too. the trackpad is still unattached.
tried some combinations-- removing one or cables

atlast i flashed my backed up bios
connected my trackpad too -- everything boots up to windows like there was nothing wrong ever
my usb also gets detected in windows, trackpad works fine too
but i still cannot enter into bios with or without trackpad also with and without usb

i am stumped - either i can have perfect bios with no windows and no trackpad
or i can have windows with trackpad but cannot enter bios

both get stuck as soon as i stick a usb

[Sephir0th]

The note about the Trackpad. What is that? Might be important.

A bad Touchpad can indeed cause the behaviour you're challenging right now

[claws77]

https://www.badcaps.net/filedata/fetch?id=3658240

this bios works with lcd and battery, keyboard, keyboard light and hdd and nvme and speaker and daughter board
can access bios too

this bios does not work when trackpad is connected.
serial no, model no both are wrong.
same issues booting from usb still persists.


could not boot into windows even with trackpad disconnected.
boot device not found.

reflashed my old bios - boots into windows but cannot access bios


Sephir0th may be right, will check this now
