Hey, i tried various Bios Dumps from this Thread to solve my Problem but i cant save my Service Tag.
Every time I boot up, the laptop goes into factory mode. I tried ALT + F but that didn't work for me.
In the left corner there is an red line with the following characters 8AC6D992

Can someone fix my BIOS dump?

Thank you.

1st boot, press F2, Enter in to bios setup write service tag manually
save, restart.
2nd boot press Alt+F to exit manufacturing mode

Hey @qayyum786,

thank you, for your answer.

i followed your two steps with the dump, but the bios doesnt save my service tag in the first step.
i entered the service tag into the field and pressed enter, a new window opened with a note, and I saved it.
after that i clicked ''Apply Changes" and the servive Tag field was empty again. this also happend before, too.

i compared the written bios dump with the dump on my laptop and its exactly the same. I dont think its corrupted.

can i insert the service tag into the bios dump?

Thanks for Your Reply. I couldn't check your bios. Because I had solved my problem before your reply. I had programmed my previous 8MB bin with a new (EXE extracted) 16MB bin file. Then problem solved. Service tag not saving problem and manufacturing program mode also not showing. I saved your files also.
Thanks.
