E6540 - BIOS

[Grep]

Hi,

Just got a new laptop (Dell E5430) but have found that booting from USB etc is locked down, I have since discovered the BIOS itself has been locked
is anyone able to recommend a way to unlock it?

Apparently removing the battery does not work on these models either so all i have to go on is the fact the Service number is: 54K8XW1-1F66

Much appreciated for any hlep and advice that can be provided

Kind regards,
G.

Just a suggestion but have you thought of upgrading the BIOS version to the latest available one ?
Try a search on the laptop manufacturers web site, if you decide to do this then I advise to follow ALL instructions given to the letter otherwise you can kill the laptop.
On the other hand if it's a new laptop take it back to where it was purchased from and explain to them the issue you are having with it.
