Hello. No realtek sound in OS.
After bios downgrade to version 1.8.3 laptop has such problems:
1. Shows message "Alert! Service mode jumper is set" during every boot. And ME Flash Descriptor is unlocked in OS.
2. Realtek chip and its devices are not detected in Windows(device manager) and Ubuntu. But speakers work(beep) in built-in diagnostics. Those speakers' pins are connected directly to codec so it seems to be alright.
So far I:
1. Flashed different ME cleaned dumps with SPI programmer. Some of them showed the same message and descriptor was unlocked. Some of them didn't show the message and descriptor was locked. But in both cases no realtek showed in OS.
2. Measured resistors on HDA lines from CPU to PCH and from PCH to codec, they seem to be OK. Also I cleaned motherboard.
Can something be done to provided bios dump in this sound regard?​Comment

It was done by bios.exe updater from dell support page. After that I tried to downgrade or update in the same way but results were the same no sound and the message .
Also I noticed that message and ME descriptor thing appear depending on which dump was initially flashed in chip and persist after downgrade/update of this initial dump via dell update exe to every version of bios.Comment

Hi all,
My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
The charging red LED lights up, but the charging screen doesn't show any indication.
When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
(I've tried removing the battery and resetting the device, but the issue persists.)

Hello everybody!
To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.
The thing is that I had installed TeamViewer and could log into the computer... -
Hi everyone
I noticed on the Xgpro software the BIOS backup files have extra bytes at the end when reading some chips, this is because the Xgpro software also reads the OTP region of those flash chips, and by default will append that region to the saved file
Programmer models: XGecu TL866II Plus / T48 / T56 / T76
Example: GD25LQ128D (1.8V), IC size is listed as 0x1000000 Bytes (16777216 bytes) + 0xC00 bytes, those extra 0xC00 bytes will be appended to the end of the saved file by default, resulting in a file size of 16780288 bytes
There's also an extra OTP Secu.R... -
Hello,
I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.
However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)... -
Hello Everyone,
I have Thinkpad T560 Which has corrupted BIOS. I have acquired Ch341A SPI flasher to program the BIOS externally. I see that to program the BIOS, i need a bin file for the BIOS. I was able to extract the .exe file of BIOS from Lenovo given here in this link:
https://pcsupport.lenovo.com/au/en/p...me=BIOS%2FUEFI
In the extracted files, I see that BIOS containing file has extension .FL1 and I need to extract or convert it...
