    Probably the chip was not read correctly, and the dump posted by theGenova is corrupted.

    Yes indeed, just checked the file too:

            After programming just close the AsProgrammer, open the program again, read the content of the chip, save the file as let's say TEST.bin, then compare the TEST.bin with the 640G2_ME CLEAN.bin with the Total Commander.

                Excellent, so you do the programming of the chip fine.
                Try to power up the laptop.

                    OK, since your initial dump was apparently corrupted there is no need to try again with it, try the dump in that post, it should be OK.

                                        Can you post a picture of the serial number on the base cover sticker, or write it here.

                                            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...
