I just bought a used dell e5510 15.6" from ebay. I have checked the motherboard and daughter board.
They are all e5510 parts but the BIOS is E5410 a09 version.
I try to update/downgrade with e5510 bios, but the laptop is refuse to update/downgrade because it is not e5410 bios update..
I have downgrade to e5410 version a01 and update again to e5410 a03.
So, I can update or downgrade with e5410 BIOS but not with E5510 BIOS.
What should I do in order to change the bios to be an e5510 bios?
Thanks & Regards
