Bios for Lenovo ThinkPad X13 Yoga Gen 4

[sergei66666]

Intel I5 - 1335U
16 GB RAM
Type 21F2
Board LCFC KX3B0 KX3D1 NM-E812 Rev: 1.0

Read from a working device.
I unsoldered two large chips for reading.
I read the third one without removing it from the board.
I read each chip 3 times and the dumps matched (I didn't write the firmware to the chips again for checking).

Hello, folks.
Please, forgive this dumb question but I own a 2007FPb whose logic board is FUBAR (really). Obtaining a replacement is not easy any more (or unreasonably expensive) so I was wondering if replacing the logic board with one from the same line (e.g. 1708FP or 1907FP) would bring it back to life. Are the resolution capabilities for each one "hardcoded" into the main GENESIS chip or auto-sensed and applied? Has anyone tried something similar?

Hi.

I have a ASUS K570U (board model X570UD) which had a bad EC (IT8995E-128 DXS). I ordered 2 new EC chips on AliExpress.

After I changed first chip and powered it on, nothing happened, and I found out that there was a short on +3VA_EC. I desoldered the EC and checked +3VA_EC on board, it had kOhms (cant remember exact number). Then I checked the GND and +3VA_EC on the EC chip itself and they were shorted.

Now, I soldered on the second chip and made measurements on all the pins (I have not powered the board with the new chip yet). And I found these pins...

1) Error trying to enter the BIOS
--> [F2] won't let me enter the BIOS. To enter the BIOS, I had to create a shortcut and then type C:\Windows\System32\shutdown.exe /r /fw /t 1 in the destination. This forced it to restart and enter the BIOS.
Once inside, I went to the BOOT menu, but, surprise, it wasn't there. I got the following message:

BOOT PRIORITY ORDER (img-05)
1- Windows Boot Manager
2- SATA HDD
3- NETWORK
4- Debian

2) Error trying to access the BOOT MENU
--> I restarted the notebook and pressed [F10] but the BOOT...

Hi

I have a Dell Latitude 5350 Ultra 7 Motherboard I am trying to repair that has a blown chip.

The chip is marked as eHOLH similar to the one I have pictured.

Any ideas what it does and what the pin outs are as 3 tracks have gone and need to find out what / where they went / did etc.

Dell PN of the motherboard is 08DCGW.




Below is the area I am trying to repair:



Does anyone have a picture of this motherboard in this area they could take and upload?

Cheers...

Board had some light liquid damage, nothing serious, just one bad looking cap that I removed (from PPBUS_G3H to ground), near speaker amps.
There was no corrosion as such, just few tiny spots, really minor.

The board is stuck at 5V, it draws 0.1A all the time. Only at poweron the amperage surges up to about 0.15-0.18A, then it settles at 0.1A.
I put it in DFU and it didn't do anything, wasn't detected on other machine.

Voltages all seem OK near the CD3217 chips, all LDOs are present, also no liquid damage was nowhere around those.
But measuring other...
