Inspiron 5557 no splash screen and BIOS setup access after update BIOS 1.2.6
The same issue from BIOS 1.2.5 is happening with BIOS 1.2.6. After the update, the boot screen remain totally black (no Dell logo) and you cant enter in the BIOS interface (no video at all).
The workaround is to downgrade to BIOS version 1.2.3
The windows boots as usual, and maybe this is the reason that users havent noticed this issue.
The bios upgrade/downgrade is automated. No mouse clicks are needed. Just wait computer to boot and wait some minutes. After this (blind) downgrade (because there is no video), you will see the dell logo once again and everything works as usual.
