Hey guys! Can someone please share the pinout for the bios chip?
It depletes the battery even when plugged in. Like it wont change from battery to power feed when the power cable is plugged in.

The BIOS chip type will be under that Award label. That is not why your battery gets depleted, and the board must be powered on, not just plugged for it to not use the battery.
The CMOS chip is what drains the battery. Can you post a picture of your motherboard ?
Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

The battery drain isn't necessarily related to it, but it at least looks like the diode D2 right below the battery in your pic has been teared off. If I'm to guess its an 1N4148 or similar signal diode. There's also what looks like a deep scratch close to it.

AT boards use "hard power"; the power to the board is physically cut via the front power switch when the power switch is flipped off. There is no standby power.

The diod was removed so the battery will not be charged.
