Notebook basic knowledge

      Some people will have a lot of problems when they contact notebook the first time,so I try to give you a satisfactory answer as possible and I hope it can help you.
About the CPU
Q1: "express runs counter to the" what, with the Pentium-m processors do is express tense?
Answer: "express tense" is not simply means the processor only, it is a system collectively includes the processor, chipset, wireless card. Strictly speaking, "Xun runs counter" processor in this system can only be a Pentium-M processor, not including the Celeron-m processor. So only use "Pentium-m processor +Intel eight hundred and fifty five-nine hundred and fifteenths chipset + wireless adapter" configuration of the model can be called "express tense." Consumers can be identified by Butterfly logo on the portable computer "express tense" models.
Q2: Pentium-m processor and Celeron m processor-what is the difference?
Answer: Pentium-M and Celeron-M processor of core, and framework Shang are is same of, difference main has two a: Pentium-M support automatically drop frequency power saving of Intel SpeedStep technology, can brings more long of battery using time, and Celeron-M is does not support the technology; Pentium-M than with core of Celeron m processor of second level cache high out 1 time times, such as used Banias core of Pentium-M of second level cache for 1M, and Celeron-M only for 512K.
Q3: the Pentium m processor and Celeron m processor performance differences between large?
A: and Celeron processor and the Pentium processor performance on machines in the huge gap between different performance than the Celeron m processor with Pentium m processor frequency is only about 10%.
Q4: why some Celeron m processor automatically reduced frequency?
Answer: individual models using the reduced frequency related software on the Celeron m processor, and Pentium m processors using the principle of frequency reduction lower the multiplier reaches different Seilhan fall in m is achieved through lower FSB frequency, which can cause system performance degradation. Familiar to the machine's friends know, frequent replacement of the FSB on some devices will have an adverse impact dell inspiron 1525 battery .
Do Q5:AMD processor can automatically reduced frequency?
A: similar to the AMD processor support SpeedStep "PowerNow! "Technology that automatically reduced frequency, but the effect and Speedstep is still a certain gap.
Q6: Celeron m processors can do wireless surfing dell inspiron 1501 battery?
Answer: can Wi-Fi only models are equipped with wireless network card-related, and the processor does not have any relationship. For example, Apple iBook G4 series, although not with the Pentium m processor, but can pass the AirPort Extreme wireless network cards for wireless Internet access.
