★Nearby data card coupling GND PIN adds the shrapnel
★The coupling which in soft, the hard disk machine/light drives adds the shrapnel in GND PIN
★All around respectively adds in CPU one to two shrapnel
★In AUDIO, MIC or nearby PCMCIA card coupling GND PIN add the shrapnel respectively
★Adds the shrapnel in the keyboard /LCD coupling inGND PIN
★DC IN/The sequence fu/printer /USB/PS2/VGA/IEEE1394 coupling adds the shrapnel inGND PIN

★Adds on the shrapnel in CPU in the back machine board
★Nearby battery coupling GND PIN adds the shrapnel
★Adds on the shrapnel in memory GND PIN

★Model: The shrapnel in the CPU place position, this shrapnel also has the function which shocks proof and helps to radiate
★In addition perhaps has I/O function CONNECTOR nearby the VGA chip all to have the EMI production, all may add on the shrapnel in GND PIN to eliminate EMI.
