I have Libretto W100 with Windows Home Premium 32-bit. One day, I checked system information, and there is written, that my Libretto has 2 GB of installed memory, but only 1,8 is usable. Is this a problem or it's normal? Is there a possibility to make full 2 GB usable? I tried changing some functions in my HWSetup(full performance, CPU always high etc.) and changing from eco to balanced mode, but there is still 1,8 GB.
