    Re: lenovo nm-c861 disable ram in bios

    Sorry for bumping someone else's thread, but I've just stumbled on the same issue with this board.
    System is ideapad 3 14-are05, board NM-C861.
    I'm looking for a way to disable onboard memory, either by hardware or BIOS.
    Schematic is not available, so it seems.
    Any help will be appreciated.

    Cheers.

        Both schematic and BV are available. Use the search engine. Page 7 in the schematic: Board_ID [2,3,4,5], DIMM_ONLY configuration 0010 disables onboard RAM, 5 minutes job.

          rearranging the straps does not lead to correct operation

            Sorry guys but i don't get it... if the resistors have to be in 0010 configuration does that mean that RC44, RC41 and RC46 have to be removed, and RC38 soldered?

              I don't think that the configuration number has something to do with the resistors .
              Anyway , I put those resistors but it doesn't work .

                    Hello Could you please give more details. Should I move these resistors to another position on the board? If so, to which positions?

                      Summary of BIOS Whitelist Removal Problem


                      Problem:
                      I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
                      Initial Findings:
                      • My current BIOS version is N1KET58W (1.45).
                      • I have a CH341A programmer and have successfully created two full backups of my BIOS.
                      • I have the ability to use command-line tools on a Linux machine.
                      Troubleshooting Steps & Conclusions:
                      • I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.
                      • I concluded that the

                      Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
                      by Wahaz
                      Hello,

                      I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
                      So I thought it was a Bios problem.
                      I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

                      Lenovo Legion T5-26AMR5 Desktop - Corrupt BIOS
                      by grimacelord
                      Hello there.

                      I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.

                      History:

                      1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.

                      I searched for this error online and discovered...

                      Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS

                      Hello everyone,

                      I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

                      This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

                      I have opened the laptop and identified the main BIOS chip...

                      Lenovo IdeaPad 3 - Hard Disk not recognized in BIOS
                      by mkdj
                      Dear all,

                      I have recently fixed a Lenovo IdeaPad 3 15 ALC6 that was not booting due to a BIOS issue. After flashing the BIOS, the laptop boots up, but hard disk is not recognized in BIOS. Is says "Hard Disk : Not Installed". I have tried with 2 different drives (one that I know is working on another laptop) but I get the same result. I do not know if disks were recognized before I got the laptop and fix it, but I don't see any reason why not. I can boot on USB though.

                      Here the steps I have taken to fix the laptop:
                      - downloaded latest BIOS from Lenovo Website...
