Laptop genuine battery requirements: can they be overcome?

[nivlark]

Hi there,

I recently bought a third-party battery for my Dell Studio 1749 laptop. Despite the seller assuring it was genuine, surprise surprise, it isn't and the machine refuses to charge the battery just because it isn't a genuine Dell product.
Some people with other Dell laptops have had success getting round this problem by downgrading their BIOSes to older versions that didn't have the limitiation. This hasn't worked with any of the revisions available for me, but it's clearly something in the BIOS doing the check...

...so my question is, is removing the code that does the check something that can be done through manually modding the BIOS?

This is the BIOS in question.

Cheers
