Can someone repair a bricked 11gen Mainboard, I’m pretty sure the bios updated failed, it was standalone without a battery and now there is no reaction from the board, no LEDs, only 5v from USB charger. I already tried to reset it.
I think the bios and the pd firmware wasn’t written correctly.
Assuming nothing hardware related is broken. You should be able to flash the BIOS again via an external flasher like a raspberry pi and flashrom. Someone can correct me if I’m wrong but that seems like that would be the way to do it.
Are you certain this isn’t the RTC battery failing? No LEDs of any kind isn’t very encouraging.
Just bought a new battery, still the same.
Should the Mainboard not ask for higher voltage when a power supply is connected? Mine is only getting 5v. I think the power delivery firmware is broken.
I never flashed a bios with an external flasher does I only need the flasher and the bios file?
You just need the clip that physically clips onto the BIOS chip on the board, an RPi as a flasher and the wires to connect the two iirc. @James3 this would be something you know more about, yes?
You could also try charging via a USB-A to USB-C directly into the laptop. As for the battery you purchased, was this the RTC battery or the main battery? Because the RTC battery must be the rechargeable variant and not disposable or it creates a fire risk.
I’m in the same boat. I’m sitting on two 11th gen mainboards. One failed after a bios update, and the other I got for parts on ebay that appears to have water damage. Both motherboards blink the same error code on startup though. 4th and 10th diagnostic LEDs are red indicating CPU failed to deassert sleep mode (S4) and CPU failed to reach the active state (S0).
The one without the water damage has a brand new rechargable RTC battery with a brand new 61Wh battery. Tried the mainboard reset to no avail.
Hey, I can just tell you that I had the same problem with an Ultra Series 1 mobo (see the thread in Community Support).
Reflashing the BIOS seemed daunting at first, but now after having done it it’s not that difficult.
You’ll need a programmer usb stick and another computer to do it.
If the 11th gen bios Chip is the same size as the Ultra Series 1s then you need a 6x8 WSOn8 probe (otherwise 5x6) like this one:
And a USB programmer CH341A, like in this kit:
Then Download the bios file from the frame.work site, I used the EFI shell file, it has cap files which can be extracted using this tool:
(I am usually on linux but that tool was easier to use on windows).
After extracting the BIOS you will get a BIOSFILE.FD that can be written to the chip using flashrom.
(Or download it from you package manager if you are on linux)
You connect the probe to the usb stick and then the stick to the working computer.
This has nice pictures showing it (but this uses a SOIC8 clip which did not fit my EC or Bios chips) :
On Linux (or cmd in windows I guess) you then can backup the chip with flashrom (optional but a good idea) and then write the BIOSFILE.FD onto the chip.
To do that you use the cmd/konsole/terminal command of flashrom with the write option and the BIOSFILE.FD.
If you do want to do all of that I can look up the commands I used and write them down here.
p.s.
it takes a long while to write and you have to keep the probe on the chip during it with a steady hand, quite nerve wracking for me
