If youve been shopping for a desktop replacement notebook lately, chances are that the processors in the machines youve compared were never intended for a portable PC. Even with the myriad mobile chips available from AMD and Intel, desktop CPUequipped notebooks are common.

The new chip is the Mobile Intel Pentium 4 processor (or Mobile P4 for short)not to be confused with Intels other mobile-chip families, the Intel Mobile Pentium 4 Processor-M and the Intel Pentium M).
