The HP Pavilion DV6000 is one in a popular line of consumer-oriented laptops produced by HP. Relatively inexpensive, the Pavilion DV6000 is a good all-around value for most users. Taking apart an HP Pavilion DV6000 is not an easy chore and if you plan to use the laptop again, it is important you know what you are doing or you have a large appetite for risk. If the above doesn’t describe you, consider taking the HP in for professional repair or upgrade. Otherwise, follow the steps below to disassemble the HP Pavilion DV6000.
1、Prepare a clear workstation. Turn off the laptop and remove all power components including the cord and the battery. (Turn the laptop over and you will find the tab to push and pop out the dv6000 battery.) Also remove any peripheral attachments like card readers and USB devices.
2、Turn the HP Pavilion dv6000 upside down and unscrew all the screws you find. Try to keep them separate by size so you can put them back in the same spot when and if you decide to reassemble the laptop.
3、Remove the hard drive and memory modules by pulling up on the rectangular compartments. The memory is located in the central compartment (remove by spreading latches and pulling up), and in most HP models the hard drive is located to one side.
4、Remove the optical CD/DVD drive by pulling on the drive face to the left and out of the laptop. Remove the WiFi card by disconnecting the gold connectors on the antenna and pulling the card from its slot.
5、Turn the hp dv6000 back over and remove the keyboard and power panel/media touch pad. Carefully pry the power panel up with a piece of hard plastic near the power button on the left side. Be careful when pulling not to yank the power connection as you might accidentally rip out a wire. Pull back the keyboard to reveal the connections. Disconnect the connections by carefully pulling on the tabs with your thumb and forefinger. If they are tight, wiggle them back and forth while pulling on them to loosen them.
6、Remove the screws that were underneath the power pack/media touch pad. Carefully pry up the top casing and set it aside.
7、Detach all visible connections to the motherboard by pulling gently on them, wiggling them if they are stuck. Gently pull up from the right side of the motherboard and remove. The HP laptop is now fully disassembled.
