Processor
Processor with the Intel dual-core laptop can help improve performance significantly. Many tests have been done on the laptop compare the single-core processor and dual-core, and dual-core processors provide a significant contribution in terms of speed and multi-tasking with a laptop rather than single-core processor. There are quite a lot of reference to the election with the laptop dual-core processor such as the Core Duo, Core 2 Duo and Core 2 Extreme, which clearly improve the performance of a real laptop.
Some laptops also use AMD's Athlon Turion 64 X2 dual-core processor, which also improve the performance of the laptop is very good. Well Turion 64 X2 and Core 2 Duo equally men-support 64-bit that can execute many applications without barriers.
System memory
If you purchase the laptop with the price a little expensive that the average will be provided with 1GB memory. However, at this time also have a lot of laptop available with memory capacity up to 2GB.

Select a dedicated graphic with memory capasity 256MB to 512MB or more. On the laptop type high-end desktop-replacement laptops are usually provided with enough graphic memory sophisticated.
While the integrated graphics memory it suitable for laptop, laptop used for business only, but to use Windows Vista on a laptop business a graphic memory of the more powerful again. Currently, there are some laptops that offer the ease Scalable Link Interface (SLI), which means that the laptop with this technology can run multiple graphics chips at once. As with Alienware's Area 51M m15x that bring two nVidia GeForce 8800M GTX cards engines on the cabin.

Battery life on the laptop at any time is always developed to obtain good results and long lasting. On a number of tests have been done, laptop using a Core Duo or Core 2 Duo average can survive up to 3.5 hours. But in practice the use of not only the processors but also will be used for the wireless receiver or burning can be a lot of energy from the battery. What you see is the number of cell in the battery is carried by the laptop, the more the more durable. Example 6-cell battery will be much more durable than 3-cell battery. However, the consequences will also increase the weight of the laptop. However, there are some laptop vendors which also includes the extended battery. In general, the size of a small laptop with a battery that has more durability from a laptop-desktop type replacement with a size large.
Keyboard and pointing device
Although sooner or later you can adjust to various types and size of a laptop keyboard, does not have one when you try it out first before buying.
