The RAM that is used for a laptop is not the same as the RAM that you would use in a desktop PC. The RAM that is used for a PC is much too big to be used in a laptop, so a laptop has to use a much smaller RAM card which is called SD-RAM.

Ram never holds anything in it after the laptop is shut down..so don't worry. As per the RAM compatibility...If that laptop's Ram type is DDR2 and your one's is DDR3 then it wont..but if they are same...They will.

The same way you do on a home PC.
If they both have the same Intel then I think that you should get the second laptop, th Intel with a laptop can effect the speed greatly, the more the cores in a laptop the better and faster your laptop will be.
yes ram can be mixed

It is the same as a laptop hard drive
