Identifies the model configuration (e.g., WA985UA#ABA).
HP releases multiple versions of the BIOS configuration utility (often called "BIOS Configuration Utility" or hpbqxxx.exe ). Version 138 was widely circulated because it supported a broad range of Intel 6-series, 7-series, and early 8-series chipset motherboards (roughly 2011–2015). Later versions added security checks that prevented DMI editing.
If you are repairing a modern HP laptop, look toward HP's official BCU suite instead. For those maintaining a fleet of HP ProBook 4540s or EliteBook 840 G1 units on a production line, keep a verified copy of hpbq138.exe and the DMIFit wrapper on a legacy USB drive—it is irreplaceable.
