Proper voltage must be supplied for reliable operation. Most laptops now use Voltage ID (VID) programmable voltage regulators to allow the processor to program the correct voltage during power-on. If your laptop does not use a VID programmable voltage regulator, it should come with jumpers or switches to set the correct voltage. Consult your laptop manual for instructions on setting the proper voltage. Since the operating voltage of Intel Pentium M Processors may be changed as the processor goes through stepping changes, VID-programmable voltage regulators are the preferred solution.
For complete voltage information, refer to the Intel Pentium M Processors Datasheet.
