In this guide I explain how to disassemble an HP Pavilion 15-cs series laptop. There are many different configurations in the HP Pavilion 15-cs computer line and this disassembly guide should work for most of them. In this particular case I’m taking apart an HP 15-cs0064cl model.
Here are just a few of the many other models supported:
- 15-cs0025cl, 15-cs0051cl, 15-cs0051wm, 15-cs0052cl, 15-cs0053cl, 15-cs0057od, 15-cs0063cl, 15-cs0064st, 15-cs0065cl, 15-cs0067nr, 15-cs0072wm, 15-cs0073cl, 15-cs0075wm, 15-cs0082cl
- 15-cs1053od, 15-cs1063cl, 15-cs1065cl, 15-cs1067nr
- 15-cs2021cl, 15-cs2051od, 15-cs2062st, 15-cs2064st, 15-cs2073cl, 15-cs2079nr, 15-cs2082tx
- 15-cs3063cl, 15-cs3065cl, 15-cs3071nr, 15-cs3073cl, 15-cs3075cl, 15-cs3076nr, 15-cs3078nr
During the disassembly process I found the following advantages of this model:
– The motherboard has two memory slots available for RAM upgrade.
– The laptop supports a regular 2.5″ SATA hard drive and a PCIe M.2 SSD.
– Both cooling fans are easily removable.
– The DC power jack is not soldered to the motherboard.
For this disassembly you need just a few basic tools: Phillips screwdriver #1 or #0, case opener tool and tweezers. At the end of this guide you will find a link to the official HP 15-cs series laptop service manual.
Base cover and battery removal
There are three screws hidden under the rear bottom feet. These feet are self-adhesive and can be easily removed.
Remove six screws securing the base cover.
Start separating the base cover from the top case assembly. I found it’s easier to remove the base cover if you start somewhere around the display hinges area.
Continue lifting up the base cover with your hands and remove it completely. You’ll have to apply some reasonable force to release multiple hidden latches securing the cover.
Remove four screws attaching the battery to the case.
Lift up and remove the battery. There is no battery cable, it’s plugged in directly into the motherboard.

Memory and hard drive removal
Remove both memory modules if you want to replace or upgrade them.
Remove two screws securing the 2.5″ HDD bracket and disconnect the hard drive cable from the motherboard.
The PCIe M.2 slot located just above the 2.5″ hard drive.
Here’s how to release the hard drive cable.
Lift up the locking tab to unlock the connector. Pull the cable out.
Lift up and remove the 2.5″ hard drive with the cable attached to it.
Cooling fans and Wi-Fi card removal
Remove five screws securing two cooling fans. Disconnect both fan cables from the motherboard. Both fans are identical and have the same service part number: L25585-001.
Lift up and remove the first cooling fan.
Lift up and remove the second cooling fan.
Disconnect two antenna cables from the wireless card.
Carefully pull the antenna head up to un-snap it from the connector on the wireless card.
Remove one screw securing the wireless card and remove it from the motherboard.
DC jack and display panel removal
The DC power jack mounted under the right display hinge. Let’s remove it first.
Remove two screws securing the right display hinge. Un-route wireless card antenna cables from the guided path on the side of the speaker.
Lift up the right display hinge. Now we can access the DC power jack.
Unplug the DC jack cable from the motherboard. Un-route the cable from the guided path on the top case and the side of the speaker.
Lift up the DC jack from the case and remove it.
Remove two screws from the left display hinge. Disconnect the display cable from the motherboard.
The display cable can be removed after the connector is unlocked.
Lift up the left display hinge.
Lift up the top case assembly and remove it from under the hinges.
The display panel has been removed.
USB board and motherboard removal
Remove three screws securing the USB board and disconnect the I/O cable from the motherboard.
Remove the USB board.
Remove eight screws attaching the motherboard to the top case.
Disconnect the following color-coded cables:
– Media card reader cable (orange).
– Keyboard and keyboard backlight cables (green).
– Touchpad cable (blue).
– Speaker cable (pink).
Four screws color-coded in red are different from four screws color-coded in yellow.
Lift up and remove the motherboard from the top case.
Here’s the other side of the motherboard.
HP Pavilion 15-cs series laptop has a “non-removable” keyboard which is permanently attached to the top case. There is a way to separate the keyboard from the top case but it’s not easy. If the keyboard failed, it’s easier to replace the entire top case.
The touchpad, on the other hand, is easily removable.
