dragon2224[USER="445520"]dragon2224[/USER] I hope I have not hijacked your thread with my own problems. I agree that the GigaDevice chip on this board cannot be programmed using a clip.... -
I agree. Probably code for the PD controller(s). In the case of this Samsung, it just flashes the blue LED continuously whether it is connected to USB-C power or just running on the battery alone. Since it appears to charge the battery using USB-C power, I am assuming that there are no problems with the PD controller....Leave a comment:

This Venus motherboard has two BIOS chips: a 16MB GigaDevice near the CPU, and a 1MB Winbond near the edge of the laptop. I am not sure where to get the 1MB BIOS, which I believe is for the Embedded Controller (EC).

I have tried three different BIOS images on this Venus motherboard, and it still will not POST. I powers on with no display, spins the fan, and flashes the blue LED.
I replaced the ME region with two nearly identical clean replacement.
I tried using a factory clean image -- [950XDB] Venus-15 TGL BIOS (P12RFW).
Although I haven't fixed the laptop, I don't think I have failed, since I learned how to use the ME Analyzer and the Intel Flash Image Tool.
Thanks to all who helped.Leave a comment:

Thank you for these files The P12RFW file contains a 16MB P12RFWB.bin file, which looks promising. It just needs to have the model, serial number, and Windows product key copied into it.
The P13RFW may be corrupted. Windows File Explorer could not open it, so I had to use 7-zip. It contains a P13RFW.bin file that is only 10MB in size, and appears to be incomplete.
Thanks again....Leave a comment:

Question about these Galaxy Book Pro laptops:
The VENUS-13 motherboard has two BIOS chips.
GigaDevice 25R127DSIG is 16MB.
Winbond 25Q80DVNIG is only 1MB.
Does the smaller Winbond chip contain BIOS code for the EC chip or for something else?
If the laptop will not POST, is there anything I can do to fix this smaller BIOS chip?
Thanks

I ran the ME Analyzer and the Intel Flash Image Tool against my supposedly corrupt BIOS image above, and created the attached outimage.bin file.
However, when I wrote the image back to the GigaDevice 25R126DSIG chip, the Galaxy Book Pro behaved exactly the same as it did before I went through all this.
As I said, I purchased an identical working motherboard, which will arrive in several days. If it does work, I can clone its BIOS to see if it will run on this faulty motherboard....Leave a comment:

I tried an earlier version of FIT, and it appears to have worked:

I copied my BIOS dump file NP950XDB-BAD-GD25R127D.BIN and ME Sub Partition.bin into the FIT WIN32 directory, and ran FIT:

In which directory should I place this ME bin file? The same directory as the BIOS dump bin file that I open with FIT?
Thanks for answering newbie questions....Leave a comment:

This is my first attempt to use FIT to clean a BIOS.
I built and ran ME Analyzer v1.307.0 r359.
I downloaded 15.0.35.1951_CON_LP_B_PRD_EXTR_4D29C2A9.bin, and renamed it as "ME Region.bin".
I downloaded FIT 15.0.30.1716, but it says it can't open my BIOS image file.
I think I need to download FIT 15.0.35. But I just can't find a link to it on the winraid site or the mega site.
ME Analyzer output:

Samsung Galaxy Book Pro NP950XDB-KC3US
This BIOS dump came from a Samsung Galaxy Pro NP950XDB-KC3US that will NOT POST. It powers on, has keyboard backlight, fan spin, and a flashing blue LED near the USB-C port.
I don't know if anyone here can clean this BIOS dump for me. I have purchased an identical used motherboard, which will arrive next week. I should be able to get a good BIOS dump from that working board.

I doubt this will help, but I have uploaded a BIOS dump from a Galaxy Book Pro that does NOT POST. I hope I can get it cleaned one day, but I need to find a dump of a working BIOS for this model. The Venus-15 BIOS dumps may work. I will try them.

Well, cleaning the BIOS was worth a try. It had all the classic symptoms. Now I have a T48 programmer and a thirst for knowledge. There are no failures -- only learning opportunities!

Thank you very much for your help. I will use your BIN to program my BIOS chip some time this week when I have time. I will let you know if I get a good POST using it.

I recently bought a Dell Inspiron 5570 laptop, service tag H0GFXR2, from an eBay seller. The eBay item description stated, "This laptop does not power on - no lights, no beeps."
The motherboard is a LA-F114P, Rev 1.0 A00, 2017-09-04.
I have removed the motherboard from the chassis, and tested it using a charger only, with no batteries. The motherboard does power on, but it does not POST. There is no screen output, and I have confirmed that the screen and backlight work fine using the "press D, then Power" procedure to display solid colors on the screen....Leave a comment:
