5. CPU Upgrade

So much for the outside of the notebook. Let's get inside and change the CPU. After my first article about mobile CPUs several readers contacted me about changing the processor. The L8400B notebook uses an uPGA2 processor that can be replaced quite easily.

The L8400B uses a 3300mAh Li-Ion battery pack

This part of the notebook adds ~400g (about 13.5 ounces) to the total weight of the system. Big batteries add to the system weight, but provide a longer time without the need of a connection to AC power.
