My Asus 1015PX netbook is slow offline and online. It has an Atom N570 dual core processor. However, diagnostic tests detect four processors which is very confusing. Does my netbook have an extra processor or is functioning on only one core? Diagnostic tools could detect only core, not two. Only detected almost complete information on cpu0, gave little information on cpu1 and gave no information on cpu2 and cpu3. Cpu1 is partially functioning on a extremely limited level. Cpu2 and cpu3 are not functional.

HARDWARE DETECTION TOOL IN PARTED MAGIC

Main Processor (4 logical/4 physical)
CPU cores: 1
CPU enabled: 2
CPU threads: 4
L1 cache 0K + 0K (I + D)
L2 cache 512k

(Hardware Detection Tool detected only one core, whereas N570 has two cores. Hardware Detection Tool detected two enabled CPUs whereas there should be 4. L1 cache is zero.)
