I am working on a Samsung Laptop NP900X4C-A01CA. The status right now is NO DISPLAY but the motherboard is drawing .75 milli amps (Amps fluctuates up & down a bit) & the CPU & the GPU even gets hot. VCORE voltages are all good & all all voltages seem to be good. Can anyone repair/fix this Original BIOS fo this laptop. Thanks in advance.

Extract the DMI from the EVSA store using UEFITool (extract as is, just this EVSA store,not all of them) or with a hex editor 70AC00 - 70ADFF
Samsung bios extractor attached.

Re: Samsung NP900X4C-A01CA BIOS
Thanks Peste & SMDFlea.. really appreciate!!! Going to do it for the first time.. Let's see how far I can go with this. So you mean I have to Extract the DMI from the EVSA Store & drag it to the Samsung Extractor with the Original BIOS Bin Files???Comment

Re: Samsung NP900X4C-A01CA BIOS
Thanks SMDFlea., 1st time doing this, so confusing. As I understand, 1st the original Samsung BIOS have to be extracted with the attached tool. & then extracted file need to be written onto a new BIOS chip. My apologies, did not get it, once I do it then it will be easier & even for everyone in this world. Thanks & thank you.Comment

Re: Samsung NP900X4C-A01CA BIOS
The extracted file needs editing as it has a capsule header ,Select off-sets 0 - 1CF (length 1D0) ,delete.Then there`s more editing to do to make it the right size... its a 3MB update (bios region).Originally posted by mferna14 View Post

Re: Samsung NP900X4C-A01CA BIOS
Thanks you so much SMDFlea., when I download this BIN file which you have send me, is it already edited as I see the properties of it, & it 8MB. So I believe you have send me the edit version file??? Right? or should I delete the off-sets 0 - 1CF (length 1D0) & then this will be the correct file to be programmed on the BIOS Chip? ThanksComment

Re: Samsung NP900X4C-A01CA BIOS
OMG Hardware1 it's working like a charm. Thank you so much. I was wondering if you could let me know what have you merged into the original Bios, or if you could point me out some tutorials.
Thank you againComment

Good to know, You're welcome.Originally posted by Kambi13 View Post
After getting the file as you did in Post #16. This file isn't a Full BIOS Image (It's just a BIOS Region), so I replaced it with the old one (You can use UEFITool or HxD) then I cleaned the ME Region.----------------------------------------------------------------------------------------------------------------------------------------------------------------------
