                        Buy a programmer, find bios and ec chips of device, use that programmer for read data from bios and ec chips , post both that files here.

                              Use the Rc unlock tool with the 16mb chip at the back of the board , works fine with 840 g7, i believe it will work fine with this too.

                              for easy access you can use the ic test clip probe,no need to take out the chip

                                      Ofcourse . In the first boot, you have to go into bios setting for dissable all the security options.

                                            Hi Everyone,

                                            I'm facing a problem with a locked bios with a password and i can't find how to remove it...

                                            The small computer is only booting on a M2 ssd Windows partition and i get a "signed partition error" if i try to boot on the same SSD with another Os (linux for example).

                                            the Computer is a Unowhy small pc

                                            After failling trying to boot on other "none Windows" partition, i wanted to try to remove the bios password.

                                            My first attempt was to get the bios dump from windows...

                                            TONGFANG "GM7TG7P" Bios Password Problem?
                                            by traxformania
                                            Hello,

                                            I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

                                            But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

                                            I'm trying to reset my bios without success.

                                            I tried :

                                            -I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...

                                            Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

                                            My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

                                            Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....

                                            I removed the BIOS password thanks to the help of one of the friends of this forum.

                                            The batch from which the password was removed works correctly but... after some time, the BIOS password is set again, I reprogrammed the batch with the removed password, it's ok, there is no password, I set my password, ok, I can enter the BIOS with my password but...

                                            I need a BIOS dump for the Samsung S49CG934SU monitor
                                            by Habble7
                                            The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

                                            Suspected Cause:
                                            I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

                                            Troubleshooting Attempts:
                                            ...
