I know a couple others with this model i can ask as well, does the region the laptop is meant for matter or is that something you can easily fix with a quick edit? In addition to doing the bios dump, can you grab RWEverything from here and use it to read SMBIOS structure, then save it and link that here. i also had to fix this after lenovo replaced the mobo because i too got stuck with the ideapad version of vantage. also, i think vantage uses the SKU string to identify models.
#LENOVO VANTAGE BIOS UPDATE 10 64 SERIAL NUMBER#
do you know anyone else with the same exact model you could ask to do a bios dump, it would probably be easier to change only the serial number from a working bios than it would to figure out and populate your bios with all the correct info. You might want to grab the intel firmware flash tool and do a bios dump and link it here. im guessing gsync probably doesnt work either? your model should have it since the model number ends in “g”.
im wondering if the last owner just flashed the binary file from an update exe since you seem to be missing every variable, not just serial number. Wait for Lost_N_Bios to respond, outside of using LVAR for this purpose i wouldnt feel comfortable telling you to try any other methods i’ve never tested myself. the serial number your trying to set belongs in /ln Have you tried resetting bios to its defaults > reboot > disable secure boot > try lvar again?Īlso, the number your trying to set as the serial number in your pictures is not meant for /sn which is a different number entirely and its longer. this tool should work on that laptop, it works on the non-gsync model of the same laptop so it must be something else getting in the you upgraded or downgraded bios at all since owning the laptop? (if not you could try going up or down to a different version, and try again) I know in my bios dump i can see these variables but tbh i dont know how manually editing them that way would work or if it would cause checksum issues, you would probably know that. is there possibly another bios option that might be interfering with the tool? platform trust/tpm? fastboot cfg lock? bios lock? i’ve never seen it return a bunch of zeros like that before either. THank you a ive seen it working on Y740, a couple ideapad’s both intel and ryzen, a y520 and my legion 5i. Hopefully I could get further instructions from you Both the original name and “lvar” performed the same result). I attached the photos of my BIOS and commands (I did rename the modded exe to lvar.exe for easier command. I don’t know if this is normal or strange therefore I also list it here. Trying running the /r /sn and the CMD showed lots of line with 0000000000000, not showing like “Not Found” as in the pastebin of. Check the ME FW: it showed “12.0, Build 1307, Hot Fix 20” with HWInfo64, but no similar line in the main page of BIOS What I did before testing with the modded Lvar: However, after the reboot, the /sn and /pn were still not updated, just said “Invalid” as before. I ran the CMD with new modded Lvar and it did show “Success”. This condition was before I received the machine, therefore I really don’t know the exact reason(s). For your help and sorry for being slow in responding due to some workload in the office time.
