Notebook Processor

Many people believe that in Notebook computers the CPU is soldered on the motherboard and thus replacement or upgrade is impossible, but the real thing is that they can be replaced relatively easy. Not all notebooks come with proper documentation on how to disassemble the notebook and configure it for a new processor. But mostly all latest notebooks behave similar to a desktop computer and replacing the processor on the motherboard is also quite similar. When the processor is replaced the notebook automatically configure the parameters to match the new processor. This may not be possible be every notebook computer but depends upon the make and model of the notebook..


The other thing which should be kept under consideration is the cooling requirements of the new CPU. Suppose that a 1Ghz CPU is replaced on the place of a 566 Mhz CPU. Because of more clock speed the new CPU produce more heat but the cooling mechanism is unable to withstand that much heat and thus the CPU get burnt due to over heating. Also this new CPU extract more power from the battery and hence drains the battery faster. Here the idea is to go for low voltage version of Mobile CPUs.



A 750MHz Low-Voltage Mobile Pentium III CPU, offers a good combination of performance and low power drain.

If you have a Mobile Celeron notebook , I think you do want to upgrade it to Mobile Pentium III not only to enhance the speed but because of the step speed feature of this Notebook.. It lowers the clock speed and core voltage when running out of battery and poses a halt instruction when the CPU is not in use. Thus having a control over the power drain.
