Anything to pay attention to? Thanks! Hi! Each file bios backup contain personal computer data like: Serial numbers for some hardware, UUID, Service TAG, NVRAM settings, MAC addresses, Windows key, e.t.c. So, you can't use file backup bios from one computer to the other of identical model. Computer will work, but not correctly. 1 Quote Link to comment Share on other sites More sharing options...
Ericw12 Posted July 28, 2019 Author Share Posted July 28, 2019 (edited) Hi Klem, Is there anyway I can rip out the proper ROM from computer A, and piece it together with the rest personal computer data of the other one, to make it proper flash? The two laptops are identical models. The second one has a lower version BIOS and the CPU fan keep spinning, and the first one with higher version BIOS does not. Thanks Edited July 28, 2019 by Ericw12 Typo Quote Link to comment Share on other sites More sharing options...

Thanks You can download from manufacturer website bios version you needed, and flash it into second laptop. Quote Link to comment Share on other sites More sharing options...

It is an engineering laptop and there is no public bios, so no such luck. Quote Link to comment Share on other sites More sharing options...
