Laptop's memory module replacement or addition

When replacing memory module of a laptop, please ensure that this laptop is turned off and external power source is disconnected. Laptop's memory modules are smaller in size than desktop's counterparts. There could be more than one slot for the laptop memory, it is necessary to look carefully for them. Home use laptops may have just a single memory slot, however laptops that are meant for engendering work may have memory slots located in different places.

Laptop's memory needs to be installed at 45 degree angle, before it can be pushed down to ensure good latch. With all kind of memory, desktop or laptop memory, please ensure good connection before locking memory. If not inserted properly, desktop memory will not be recognized, and it is possible to damage laptop memory, if extra force applied to a memory chip that was not inserted properly.

When extra memory is added, please ensure that new memory is recognized by this system.

Some laptops have RAM modules soldered to motherboard, memory there is not replaceable, in order to get more memory for that laptop, an entire motherboard needs to be replaced. It is not a trivial task, and it is costly.
