4GB of RAM in your notebook for Longer Battery Life

[James]

Tom's has yet another review of memory density, this time in notebooks.

For the extremely inexpensive price nowadays, extra memory can actually increase your battery life, as it reduces swapping (waking up the hdd.)

Although the increase in battery runtime - 13 minutes when going to 4 GB - doesn’t look like a big deal in the context of seven hours of battery runtime, such an upgrade is still worth it. On the one hand, the cost for a 4 GB kit has dropped below $100, making such an upgrade extremely affordable. On the other hand, the memory upgrade will both increase battery runtime and your system responsiveness, as well as application performance when multiple programs are being executed. Finally, a memory upgrade often can be performed with little effort, as all parts of a notebook can usually be accessed easily.
