A: No. If the CMOS battery dies, the "previous values" are lost because the volatile memory that stores them requires constant low power.
You set all your chassis fans to 0% RPM to test silence, but your CPU temperature starts climbing to 90°C while you're still in the BIOS hardware monitor. LPV will reset the fan curves to the last working configuration without rebooting. bios load previous values
By mastering the "Load Previous Values" command, you transform the BIOS from a terrifying maze of acronyms into a safe playground for performance optimization. Go ahead—tweak that voltage. You know how to undo it now. LPV will reset the fan curves to the
| Feature | Value | |---------|-------| | | All settings in current BIOS session | | Source | CMOS / flash contents at session start | | Permanent | No — you must still save to make effective | | Common in UEFI | Rare | | Usefulness | Low for modern users, useful in legacy or training | You know how to undo it now
This is where most confusion arises. The BIOS typically offers three "reset-style" options. Here is the critical difference:
