Hewlett-Packard - HP laptop repair a dedicated power connector with a chip with charging function HP 7.4MM HP notebook can boot power plug head

Product Description:

          Support new models:  DV3 4416 CQ40 CQ45 Series models!

        Because the former is the voltage detection boot, now is the pulse detection boot, so before the old models HP charging head can not be applied to new models, new models must use an enhanced version of HP 2011 HP 7.4mm head rechargeable power source for charging boot!

        2011 enhanced version of HP rechargeable power supply built-in chip 7.4MM first hole, the machine supports the latest series, with charging function (other simple power head without charging function, access to new machines with ordinary power head, unable to boot, charge, using this power head to boot, charge).

HP computer model of the chip through the adapter identification access. If the chip is damaged, HP BIOS will prompt the AC Power Adapter type can not be determind this will prevent optimal system performance and other information, press F3 to enter the system, but the CPU frequency use, the battery can not be charged.

The greatest advantage:
Using this power head with multi-function adjustable power supply can be observed at any time to change the power supply adjustable current order

Current method used to determine the mechanical failure!
