That is a option, but I'm here for a bios request where I also have my system information/DMI in the bios, so service tag, Asset tag, ownership tag, and windowskey. You also know that this belongs to a region in a bios file, but with these I can't point out a region, so that is why I asked you. Easy commend in HeX for winkey, as you know, is 010000000000000001000000000000001D000000 using search on Hex values. Also I can find service tag, but when comparing with other file there are far from eachother in file. Some bios files have a region, more compact, where this information can be found. I hoped you have a solution. When using Flash image tool for this bios I find de winkey in BIOS region, and the service tag in the CSE region, but I'm not sure if it helps that I use your standerd file from this thread, and replace both BIOS, and CSE region. I could test, but rather take bios chip not to many times from motherboard.

Once repaired, a lot of information is found to be changed and the original cannot be retained

Repairs must accept this

For people who read this information. You always can change winkey in bios file provided by ThienBui in HxD with command I mentioned in other answer. Also there are other ways to put, or change DMI in bios files. Some laptops give you this oppertunity when starting laptop for the first time, and in other case laptop have special tools, like HP, with HP DMI tattoo. Just look for option on the internet.
It's understandable ThienBui doesn't do this for all customers, but it's not a case of accept this in the way that you can't do enything about it ;)
I just whas wondering if there was in this case a quicker way, because ther are bios files where you just have to copy 1 region.
 
it starts but after restarting several times it turns off, after pressing the power button it starts for a while and turns off.
 
When changing the graphics card in this laptop, do I need to reprogram the appropriate bios to make this laptop work? I changed the card, the symptom is a bit different but still no image

Graphics card changed from N19E-Q5-A1 to N19E-Q3-A1

Not related to BIOS, including other BIOS programming, there is no BIOS as you want, I think the problem is only in the graphics card

the laptop worked for me on this bios, it started, it gave an image, but it doesn't want to work with all the ram memories connected. when I connect them separately it works, it even works when there are two connected, but when I connect more it stops giving an image. I think it's a bios issue, because I checked the ram and they are OK, the ram banks are also OK, because the laptop also works separately
