How to change model number ,serial number and uuid on my laptop ?

Hey guys
I need to know where is these data stored?
I is DEFO NOT in bios chip..

 

Why on earth would you want to do something like that?

 

Becaauusee I purchased motherboard from singapore and there is model number just 780 and serial number is 123456789 uuid is 123456789
So there is no model nr no serial ..

 

Yeah that is true ..
I have all tools all programs ... but dunno how to rewrite it
Noo no I never give my things to other persons ..
I do stuff by my self ... and looking for advice online

 

I think NBR is not really expert in this stuff due to forum rules ~~.
I think you should try some bios-mod forums or forum dedicated to the model. I use to read stuff about overwriting bios password on forum.thinkpad.com etc.

 

Hah on IBM ? :-D
I do it all day and every day in work on IBMs ( but desktops)
Thing is we have BIOS updates for machines and bios update utility ways asks :
Would u like to change model nr or serial..
You dont need to overwrite try remove battery or do some short on bios chip w
ile is laptop unplugged (even fr battery)
It always help for us..

 

Well, I remember in the dell m6600 technician guideline(not that I am a technician, but happen to reading it).
It have a line saying the technician need to enter a service tag or serial for motherboard when they do motherboard replacement and such code can not be changed thereafter. So I guess it probably model/brand specific.

 

Yeah exactly we have to do it..
It needs special bios update utility where it asks to change
I need to change on ine co i replaced mb

 

So
OK I have Sony Vaio AW Series ..
BIOS is : AMI Aptio
Tools : AMI BCP , MM Tool Aptio , Change Logo , and DMI Edit
I can use all of them but only that DMI Edit i dont know how to implement into my BIOS what then when I save some text doc
I will talk about DMI Edit I changed all details but what then next how do I putit into motherboard ?? (see below)

These are current info



Need to change from 780 to VGN-AW11XU/Q
That VGN-AW11Z/B that is another vaio aw that is correct ..

 

What exactly is the problem with it not having a valid serial? Are you trying to activate windows or something and its not working? hopefully you're not trying to get warranty support since you replaced the motherboard...

 

​

NO mate .. In reality am not bothered about serial but at least model number..
UUID seems to be original .. and i dont care about serial..
No mate no activating windows ..it has nothing to do with it..
With activating is SLIC 2.0 - 2.1 and that is in bios already ..
Nooo noo haha warranty. :-D I was actually thinking that but n.
This type of vaio been discontinued two years ago . And noone is selling it .
It ia very hard find seller with warranty
I vwouldn't have courage to do it I just repairing laptops..
But here on IBM units it is possible dunno why by original even on HPs only sony must be bloody exeption and making up restrictions! hate them..!

 

So, you used DMIeditor 125, I can't find it, could you share it? I need to edit model name in BIOS image before flashing it to my system.
