In the following guide I explain how you can remove and replace keyboard, memory and hard drive in a Compaq Presario 2580US laptop. The keyboard replacement procedure is relatively simple and you can easily do it yourself at home. Proceed on your own risk!
Compaq Presario 2580US is similar to many other HP/Compaq models. The disassembly procedure should be the same (or almost the same) for the following laptop series:
1. Compaq Presario 1100, 2100, 2500
2. Compaq Evo Notebook N1010v, N1050v
3. HP Compaq nx9000, nx9005, nx9008, nx9010
4. HP Pavilion ze4100, ze4200, ze4300, ze4400, ze4500, ze4600, ze4700, ze5200, ze5300, ze5400, ze5500, ze5600
First of all, turn off the laptop, unplug the power adapter and remove the battery.
STEP 1. Remove two screws securing the keyboard/hinge cover.
STEP 2. Start removing the hinge cover with a flathead screwdriver as it shown on the picture below.
STEP 3. Continue removing the cover with your fingers. Be careful, there is a power button board attached to the cover which is connected to the system board.
STEP 4. Place the hinge cover as it shown on the picture below. As you see, there are a couple of wires running from the cover to the system board.
Remove four screws securing the keyboard.
STEP 5. Carefully lift up the keyboard.
STEP 6. Place the keyboard so you can access the flat ribbon cable connecting it to the system board. Before you can unplug the keyboard, you’ll have to unlock the connector.
STEP 7. Unlock the connector by lifting up the white tab using your fingernails. The white tab has to stay attached to the connector. Lift it up about 1-2 millimeters.
Now you can release the keyboard cable.
STEP 8. Remove and replace the keyboard with a new one.
You can find a new replacement keyboard by the Compaq spare part number located on the back side of the keyboard. In my case the keyboard part number is 317443-001. For your laptop the part number could be different.
Here are some other components you can replace in your Presario 2580US yourself.
1. Both memory slots/modules could be accessed from the bottom of the laptop.
2. The wireless card could be accessed from the bottom.
3. The hard drive could be accessed from the bottom.
In order to remove the hard drive you’ll have to remove three screws. One of the screws is hidden under the rubber seal (yellow square). Remove the rubber seal with a sharp object and remove the screw.
Pull the hard drive assembly from the laptop.
Now remove two screws on each side of the caddy and replace the hard drive with a new IDE drive.
NOTE: your hard drive has a small jumper connecting two pins. I believe this jumper sets the hard drive to “Cable Select” mode. It’s likely that you have to transfer the jumper to a new hard drive in order to get it recognized by the laptop.
