ASUS P55T2P4 - Drained Dallas DS12B887 Battery

The CMOS battery reached the end of its life on my ASUS P55T2P4. The unfortunate side-effect is that I can no longer save any BIOS settings. On boot, the motherboard automatically restores the BIOS defaults. Date, Time, USB functionality, and more are either wrongly configured or disabled. Time to replace the the DALLAS DS12B887, a resident of this motherboard for more than 25 years, with a working unit. You can support me on Patreon:
