I am running on my T530:
UEFI BIOS Version: G4ETB7WW (2.77)
UEFI BIOS DATE: 2019-09-09
My original battery is broken and I need a white listed BIOS.
1) I created a battery patch for 2.74 and tried to downgrade my bios but the Lenovo update needs a full battery.
2) I downloaded the version of post #182 but I get with winpflash64 the error: ”Corrupted interface descriptors in new BIOS file. Part Table Signature not found in the interface. Error code -161”
3) I tried the same with phlash16.exe on DOS but a bell ring and it stops immediately.
Is there a way to install a “free” BIOS without battery?
