In the following guide I explain how to disassemble an HP G72.
This guid also works for Compaq Presario CQ72 models.
In this particular case I’m taking apart an HP G72-B57CL laptop.
I’ll go though the following major disassembly steps:
STEP 1-6: Removing the hard drive and optical drive. Accessing the CMOS battery, wireless card and memory modules.
STEP 7-15: Disconnecting and removing the keyboard.
STEP 16-20: Removing the top cover assembly.
STEP 21-26: Removing the motherboard.
STEP 27-30: Accessing the cooling fan and DC jack cable.
