How to replace dv7 main board - HP Pavilion dv7-1130us laptop

Hello thf you look closely at the place where the key fits examine it and look to see if there are any broken tabs if not the key should simply press back in it does take some pressure and you should feel a snap when it is locked in place
Now if it does not then the key itself may be faulty which means you can get a another key from a old key board or just replace the keyboard itself they really are not too expensive ok
Hop this helps
Best regards Michael

Instructions

1

Shut the Pavilion dv7 down and close the screen. After unplugging all cables from the computer, turn it over and remove the battery.
2

Unscrew the six Phillips-head screws holding the large T-shaped panel to the bottom of the Pavilion dv7. Remove the panel and set it aside.
3

Remove the keyboard locking screw--marked by a keyboard-shaped icon--from the top part of the compartment exposed when you removed the T-shaped panel. Reserve the screw.
4

Remove the black Phillips-head screw from next to the wireless adapter inside the T-shaped compartment. This screw holds the Pavilion dv7 optical drive in place.
5

Pull the Pavilion dv7 optical drive gently out of its bay, and then remove the two Phillips-head screws from inside the empty drive bay. Reserve the screws.
6

Remove the Phillips-head screw next to the circular intake fan vent in the corner of the Pavilion dv7.
7

Remove the five Phillips-head screws from inside the empty battery compartment. You should now have removed 16 screws in all. Turn the Pavilion dv7 over and open the screen.
8

Insert a spudger or other flat plastic tool into the seam between the speaker grille and computer casing on the right side of the Pavilion dv7. Gently pry up to begin removing the speaker grille from the computer. As you do this, move the spudger to a new location to pry different areas until the grille is completely disconnected. Mind the ribbon cable connecting the center of the speaker grille to the logic board, and do not lift the grille any higher from the computer than the cable allows.
9

Push both sides of the speaker grille cable lock forward until the cable slides easily out of the logic board connector. Set the speaker grille aside.
10

Remove the four Phillips-head retaining screws above the top row of the Pavilion dv7 keyboard. Lift the keyboard up and forward, and place it face-down on the palm rest.
11

Unlock the Pavilion dv7 keyboard cable connector using the same method as for the speaker grille connector. Slide the cable out of the connector, remove the keyboard and set it aside.
12

Place the new Pavilion dv7 keyboard upside-down on the palm rest. Slide the keyboard into the connector, close the lock and rotate the keyboard down into the computer. Replace the four Phillips-head screws.
13

Slide the speaker grille cable into the connector and close the cable lock. Push the speaker grille into its original position above the Pavilion dv7 keyboard. Press gently on all parts of the speaker grille until it is flush with the computer casing.
14

Close the screen and turn the computer over. Replace the five screws inside the battery compartment, the screw next to the intake fan vent, the two screws inside the empty optical drive bay and the screw inside the T-shaped compartment.
15

Replace the t-shaped panel on the bottom of the Pavilion dv7 and its six screws.
16

Slide the optical drive back into its bay and replace the securing screw.

Why don't you buy a new power cord? Rewiring these can cause a short and could fry the main board. Replacements are under $50.00, will need the model number of the laptop so I can provide a link.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

1. Remove 6 screws from the bottom of the case (as shown). These screws hold the accessory cover.

2. Remove one screw securing the CD/DVD drive. Slide the CD/DVD drive to the left to disconnect it from the motherboard. Remove the CD/DVD drive.

3. Remove all marked screws from the bottom of the notebook.
The yellow circled screws secure the keyboard cover, and the green one secures the HP Pavilion DV7 keyboard.

4. Turn the computer display-side up and open it as far as possible. Insert a guitar pick or small flat screwdriver between the keyboard cover and case and slowly move along the side.

5. Lift the keyboard cover. Be careful, it's still connected to the motherboard. Release the zero insertion force (ZIF) connector and disconnect the cable from the LED board. Remove the keyboard cover.

6. Remove the four screws that secure the HP Pavilion DV7 keyboard.

7. Lift the rear edge of the HP Pavilion DV7 keyboard until it rests at an angle. Slide the keyboard back to disengage the tabs on the front edge of the keyboard from the top cover and rest it on the display.

8. Release the ZIF connector to which the keyboard cable is attached and disconnect the keyboard cable. Remove the HP Pavilion DV7 keyboard.

I don't know how many boards there are for this model, but you can find a replacement board by using the hp part number either at a laptop parts retailer or on ebay.

Do a search on ebay using 486542-001, last check it was around $200.00

Hi,the reason why your laptop is telling you to replace Battery is,you have killed your battery without knowing by Charging it always,since you have constant power supply,you should at least after getting a new Battery,discharge it four to five times a week longer life of battery,by these i mean,unplug cord from mains let power drain to 5% or 10% before charging again while working and if fully charged and you are not making use of it disconnect and if you want to make use of it use battery instead do not connect immediately to mains until power drains from battery.Just like your mobile phone,you only charge it when need be(ie. when Battery is Low).

Thanks for using fixya, that sounds a motherboard problem, you need to repair the motherboard or replace it, or you try to take all the powers from the laptop (bat. and charger ) press the power button for 10 sec. then connect only the main without the bat. and seen if works , if not , you need to repair or replace it.
Thanks

I don't think the cable is loose but the cable could go bad. touch pad circuit board could be bad or the mother board. You have to treat it like a science project and these are the steps i would go if you want it back to normal. Replace the hole palm rest area if that doesnt fix it then the mother board. you could get a usb mouse also look in the control panel and look for the mouse and there is a troubleshoot area.
