                        There is some alternative better software you can use with the CH341A .NeoProgrammer ,AsProgrammer ,Colibri .You`ll find them all on the forum if you search. Always make 2 backups and verify they are both the same using a hex editors file compare function . HxD - https://mh-nexus.de/en/hxd/ .

                        Post your original bios backup.

                            so finally you successfully make a backup dump ?

                            is it original backup ?

                            than send me laptop your serial number

                                maybe dump is not backup properly because of your programmer tool or its software

                                        Maybe the bios chip is the one that is faulty.
