CMOS (BIOS) Battery Replacement

You can use this practice when soldering CMOS batteries. Or you can use this practice to use it without any soldering.



Battery Rebuild

There have been rumors that the logic board of the battery have been damaged, one thing i've found damaged was flexible cable, so i have to solder additional cable to make a fix. After battery have been rebuilt, the rumor that battery logic board is damaged was confirmed. Battery builtin button and leds do not indicate any signs of life and after inserted into computer it was detected as dead battery, with no charging or discharging capabilities. I will later do some research on it, but for now i have no spare time left to do this.
