Hi all, They will all work with each other although, electrically, there are some things you should note:
1. If a unit is expecting a 45 watt power supply and you give it an 85 watt power supply, you may decrease the life of both the battery and the charging unit. consider that you're pushing almost twice the wattage into the charging unit as it is rated for. In some cases this will burn the unit out faster, and in some cases, it will simply burn it out immediately. Also, consider that heat is one of the most damaging factors in battery life, if an increased amount of power is being pushed onto the battery, it will heat up more, thus, the battery will get hotter during charging probably reducing its life. 2. The other direction, charging with a 45 watt when expecting an 85 watt power supply, does not hurt anything really. It will simply make the charging process take longer. 3. You may get away with things for a while, but I recommend that you use the proper rated power supply, especially if you have any warranty left on the machine.
