It's common knowledge that water damage on many electronic devices can be mitigated using isopropyl alcohol at a high concentration.
Many guides have mentioned disconnecting the battery before using isopropyl alcohol on the device. It can be tricky to remove the battery of certain electronics devices (such as many apple laptops), so I was wondering whether someone could please inform me about the consequences of submerging the body (not the screen) of a laptop that has been powered down in a tub containing 99.9% isopropyl alcohol without unscrewing any components (i.e. leaving the lithium-ion batteries inside the device)? The amount of isopropyl alcohol will be just enough to cover the keyboard.
