Hi, If I'm not mistaken, mobile CPU's can reduce their speed with Intel Speed step feature... So if this is the case, the CPU slows itself in order to preserve power.

The CPU is supposed to be a Pentium 4 2.66Ghz, but Linux identifies it as a Pentium 4 2.66 GHz that operates at 1.6GHz: The following is my /proc/cpuinfo: processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Genuine Intel(R) CPU 2.66GHz stepping : 9 cpu MHz : 1594.431 <------------ cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid bogomips : 3112.96 I also checked with x86info, and got much the same results. I tried to search the web for relevant information, and I'm afraid I came up blank. Is this normal? Some kind of frequency scaling thing in order to save power? The results I got above were made while the laptop was connected to the electricity. This is also consistent across different kernel versions. I tries 2.4.23 and 2.6.0 and 2.6.1 and got exactly the same results each time.
