I have an Ideapad 330S-15IKB PC whose motherboard I changed today. It comes from the famous Aliexpress site … The problem is that the MTM, Product ID etc is not present in the bios and my keyboard does not work on the digital pad side.
I could read that it came from this missing information and I would like to fix the problem.
Is it achievable? I found a website explaining how to extract a bios.exe file and get an editable .fd file but I don’t know how to extract the current bios from my computer. Is it necessary or is there a tool capable of rewriting in the bios directly under Windows (or bootable USB key)?
Hi friend, have you the previous bios backup from the older MoBo , have you the System Data to know which were into the older one ? Have you an SPI CH341a programmer … Use this tool run it as Admin and upload the result file :
I can’t do a backup from the older MoBo because it doesn’t work anymore. That’s why i change it for a new one. I have an SPI programmer , maybe i can try to read the bios from the older MoBo with it ? To be honest, i don’t remember how to use it.
@Tiripstruk It’s very easy , you have to download the software for the Win10, ASProgrammer 1.41 , install it (install driver Parallel version), and then connect the clip to eeprom and try to find your eeprom , there is a buttom “?” it will show the Eeprom ID found, double click on the first one and try to read the chip. Here is the tool :
On the old MoBo, impossible to read the ID of the chipset. I put all in the right side , i’m sure of it but all the time, it’s unknow. Maybe it must have batterie or adapter plugged in?
Impossible to read the bios with the hardware… I try on other board with success but not on this one. Maybe it’s better to try with software solution if it’s possible? Thank you
i just have the sticker under the laptop. I have MO , Mfg date, MTM,Model name, Factory ID, S/N and it have a sticker on the MoBowith a number like : 311204510611S2… Is it ok ?
Is there a step by step guide to modifying dumped Bios with a CH341A please? I took too much time at BDMaster (thank you very much for everything) and I don’t want to abuse … Thank you PS: BDMaster, send me a PM just to pay my dues. Thank you
@Tiripstruk hi friend, there is no problem to help you , everytime you want i will be available fro you … Here is a Guide started by Sml6397 and i am writing too, you will begin to learn about UEFI and a Phoenix Bios , but it’s full of experiences …
@Tito Now i can feel at home Nice to me you are here my friend, from long time i didn’t make nothing i’m back again , but on MDL a lot of things are changed … Good to know you are here too so i will write you here !
So after change again the MoBo, issue still the same… The numeric part of keyboard doesn’t work. I try to do a fresh install of Windows and nothing more.
When the PC starts, it is impossible to turn on the Num Lock key but as soon as Windows loads, then the indicator lights up without ever working. It is not possible to turn it off and the number keys as well as the “+”, “-”, “Enter”, “*”, “/” and “Del”. I tried a lot of things with BDMaster (thanks again) but it doesn’t work.
I ordered a new keyboard but the problem was the same. I admit being totally lost …
Strange thing: if I write the original bios on the new card, it will take more than 30 seconds to start. If I inject the bios supplied with the motherboard, then the pc starts up instantly. I don’t understand what reconditioners are doing in China, it’s really weird …
Hello; I have the same problem with a motherboard that I bought on Aliexpress for the same laptop model: 330s-15ikb, in the bios the MTM and Product Name are INVALID. I also cannot access the information of the original board because that board no longer turns on and I don’t have an SPI CH341a programmer. I have tried to use the Lvar tool but I have not been successful, when I have written, using cmd window with administrator permissions, for example, the command: LvarWin64v229.exe /w /pn /c "Lenovo Ideapad 330S-15IKB" responds "Other error."
What am I doing wrong? Is there any way I can fix the problem?
