If you replace the battery, and your computer is unplugged will you lose your settings on your computer? Hopefully, this isn't too much a computer Noob question to ask? TIA
Older computers used to keep the BIOS settings saved in CMOS using this battery so a loss of battery power would cause you to lose any custom BIOS settings (e.g. they should revert back to factory default) AFAIK, all modern PC's store these settings in non-volatile RAM (NVRAM) so that they dont depend on the battery power. In any case, if you have made any customizations to the default BIOS settings you may want to record them (on paper) before you do the battery swap just to be sure. Most people dont mess around with the BIOS settings these days anyway.
