| The chipset of that laptop is not capable to address thze whole 4GB RAM. | That's not untypical for systems of that age (Intel T2300).
To back this up:
https://en.wikipedia.org/wiki/Dell_Inspiron#Inspiron_9400.2FE1705 says about the same thing.
It also says that the GM945 (or PM945) chipset is used. Intel says that 4G is max for those chipset: http://ark.intel.com/products/27857/Intel-82945GM-Graphics-and-Memory-Controller http://ark.intel.com/products/27858/Intel-82945PM-Memory-Controller
