Forum rules:Click here to view the forum rules

  1. Topic title should contain: the device's manufacturer, full model and the brief description of problem.
  2. Topic message should contain: the PCB marking code (required in case of hardware repairs), an extended description of problem, things you have checked/replaced/measured, your conclusions and the question. If you are not able to find the PCB marking code, please read THIS TOPIC. If you still cannot locate the PCB markings, please upload a clean, both-side photos of the mainboard - it is required to remove any films, modules or brackets possibly covering these markings.
  3. Before posting a new topic please read all topics in TRAININGS subforum and make a preliminary diagnostic based on the content of those trainings.
  4. Uploading of any complete schematics, BIOS / firmware files or any other kind of documentation, or linking to 3rd party websites with such files, is STRICTLY PROHIBITED. You can only upload the small portion of documentation or, link to BIOS file on UNVERIFIED BIOS FILES subforum, which simplifies the diagnostics/repair. You are not allowed to upload more then one complete page of instruction/schematic per single topic. The file you upload must not contain any watermarks, "confidential" markings, links or email addresses and cannot be password-protected.
  5. It is only permitted to describe one faulty device per single topic - you should always open a new topic for each subsequent device.
  6. Requesting of the full schematics, BoardView files, BIOS files or any other kind of documentation is NOT ALLOWED in this subforum. If you need to ask for any of these, you should open a new topic in DOCUMENTATION/BIOS REQUEST subforum.

Try to reflash the BIOS chip. Don't forget to save the old dump. If it doesn't change anything, replace the KBC (SIO) chip.


If I buy new KBC (IT8110E) it will programming itself?

- Have you tested the machine with the RTC battery connected?
- Does the machine keep the date and time settings in BIOS after disconnecting the power supply?
- Check if the RTC battery is functional (the voltage on it should be around 3V), when it's connected to the board.

If I'm not mistaken this KBC chip does not require programming. It probably loads the program from BIOS chip every time when you plug the power supply to the board.

1. Yes, with and without RTC battery
2. Device is keeping settings of bios
3. Battery was changed to new on the start and has 3V
4. Ok, understood. I thought that KBC could be programmed by PCH :) I will remember.

Which pin of KBC IT8110E is related to FAN? It will be 41 (0V) and 29(1.9V)?
