I think i'll reflash the EC firmware

Thanks for the suggestions. Here's an update based on my measurements:[LIST=1][*][B]+3VALWP Resistance:[/B] I measured the resistance to ground for the [B]+3VALWP[/B] rail (at PJ302 / output side of PL301). There doesn't appear to be a short circuit on this rail itself.[*][B]Enable Signal Trace (3V_EN path):[/B] I visually inspected the path for the [B]3V_EN[/B] signal, including the components in its creation circuit (DB1, RB19, RB20 on sheet 84) and the connection towards PU301 (Pin 12). I did not find any obvious trace breaks. The issue seems to be that the enable signal is not being generated...

After a few days of diagnosis, I found that the +3VALW is missing, while the +5VALW is okay. I noticed that the 3V_EN_R signal from the EC KB9052QD is also missing, and I don’t know why

I'm using DowSil TC-5888 with a very detailed analysis from [URL]https://www.igorslab.de/en/the-worlds-first-interactive-thermal-paste-database-real-measurement-data-material-analysis-and-objective-fact-check/[/URL]​https://I'm using DowSil TC-5888 wit...heck/[/URL]​I'm using DowSil TC-5888 with a very detailed analysis from [URL]https://www.igorslab.de/en/the-worlds-first-interactive-thermal-paste-database-real-measurement-data-m

Thanks, but the laptop doesn't boot after flash that bin file, the power led only blink a few second and then turn off and the keyboard has no light....

Hello everyone,

About a year ago, I accidentally erased the firmware on the SPI ROM of a Thunderbolt retimer in my computer, mistaking it for the main BIOS chip. Since then, the Thunderbolt controller no longer appears in Device Manager, and I'm unable to use Thunderbolt functionality.

For context, my system has two retimers: UT5 and UT3. The one I erased is the UT3, which uses a W25Q80DVSSIG chip. In an attempt to fix this, I used a CH341A programmer to copy the ROM data from the UT5 retimer to the UT3, hoping it would restore functionality. Unfortunately, this didn't...

I still need help with the BIN rom file for this Winbond W25Q80DVSIG (UT3 on the schematic), thank you very much...

Hi thank you in advance, this is working like a charm now ...

Hi. I came here to learn and sharing. Thank in advance all you guy help !...

I found my motherboard number: GH51G LA-L181P Rev:1B 2021-05-24, dump file in #99...

Yes, sir , here my bios dump. I remebered last time i setting undervolt in overclock section to override and laptop restart with black screen.

Additionally, the dump file I send here is of the green circle, the XMC QH128AHIG.

[B]I also mistakenly erased the Winbond W25Q80DVSIG EEPROM chip (drawn in the red circle) because I thought it was the BIOS chip. Can anyone help me with the BIN file for it? Thank you in advance![/B]
