Today I explain how to disassemble a HP Pavilion dm3 series notebook.
In this particular guide I’m taking apart a HP Pavilion dm3-1035dx Entertainment Notebook but the guide should be the same for all other models in Pavilion dm3 line.
Before you start, make sure the computer is turned off.
Removing the hard drive, memory modules, wireless card and CMOS battery shown in steps 1-7.
Remove the battery.
Remove five screws securing the hard drive and memory covers. Remove both covers.
Remove two screws securing the hard drive and slide it to the left to disconnect from the motherboard.
Now you can remove the hard drive.
As you see, it’s a standard 2.5″ SATA hard drive.
Remove both memory modules.
In order to remove the memory module you’ll have to follow two simple steps:
– carefully spread lathes on both sides of the slot until the memory module pops up at a 30 degree angle.
– pull the memory module from the slot by the edges.
Disconnect both antenna cables from the wireless card.
Remove two screws securing the wireless card.
Remove wireless card same way you removed memory modules.
Disconnect the CMOS battery cable from the motherboard and remove the battery.
Removing the keyboard shown in steps 8-12.
Remove two screws securing the keyboard on the bottom.
Push on the keyboard through the openings in the battery compartment.
Lift it up as it shown on the following picture.
Carefully lift up the keyboard and access connector underneath.
In order to remove the keyboard you’ll have to disconnect the cable first.
On the following picture the connector shown in the locked position.
Lift up the right side of the brown clip so it opens at a 90 degree angle.
On the following picture the connector is shown in the unlocked position.
Now you can pull the cable from the connector.
Remove the keyboard.
The best way to find a replacement keyboard is searching by the HP part number.
In my case I had two different HP part numbers: 580687-001 and 573148-001. I guess both part numbers are compatible.
Removing the top cover and cooling fan shown in steps 13-18.
Remove marked screws form the bottom.
Remove six screws securing the top cover assembly.
Disconnect the top cover cable (left arrow) and touch pad cable (bottom arrow).
On some HP Pavilion dm3 models you’ll have to disconnect one more cable – the Bluetooth module cable.
On the following picture you can see the top cover cable disconnected.
On the following picture you can see how to open the touch pad cable connector.
Start separating the top cover assembly from the bottom.
You can use a thin piece of plastic (I’m using guitar pick) as a case cracker.
The top cover assembly has been removed.
On the following picture the notebook shown with the top cover removed.
Remove two screws securing the cooling fan.
Disconnect the fan cable from the motherboard.
Remove the cooling fan.
The cooling fan part number is printed on the white sticker. In my case the part number is: 580696-001
By the way, in HP Pavilion dm3 the power jack is not soldered to the motherboard. The jack attached to the power harness.
When the power jack fails, you can disconnect the failed jack harness from the motherboard and replace it with a new one.
