    • the battery is a 3 volt cr2032 made by panasonic, replace with a similar battery to yours. it faces + down on my model, but it might not on yours, so you need to check before removing

    • to get the battery out, put your thumb under the battery, and push up while pulling the battery away from the motherboard (couldn't get a good picture of this)

    • If your battery goes ballistic and flies into the lower portion of you computer, you have to get it out or you risk permanently frying you desktop, use a magnet to remove the escaping battery

    • to reassemble you computer, follow these steps in reverse order

Conclusion

To reassemble your device, follow these instructions in reverse order.
