I did this the other day too;
Asus P/I-P55T2P4 has an ST Mirco M48T86PC1 RTC module, with an internal battery soldered to the board. When the battery degrades the board cannot save settings.
Desoldered, but still stuck - checked all the pins wobbled and then used a spudger to lift it out. Was a tight fit.
The Dallas DS12887+ is a pin compatible replacement that you can still buy from reputable sources. Added a socket and it slotted right.
For the first boot I forgot to clear the CMOS with the jumper, and the board was not happy. Reset it and all is well!
Having that socket means it'll be much easier to replace when it next dies!
