How do you remove the back casing?

There are 2 screw areas about 4-5" above the bottom of the casing that are different from the rest that seem to be holding it in place even though the screws are removed.

There are plastic tabs that hold the back in place in order to get the screws to align. Use a flat head screw driver or kithchen knife to pry the tabs apart and slip the cover off.

How do i open dv7-1451nr?



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

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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

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

I need a body case for my vaio vgn-nw120j/s

The panel you refer to is the Palm Rest Cover (Sony)

Covers the top of the body of the laptop, has the Touchpad in it, and the Keyboard is in the top/middle.

I would suggest going to Ebay, and looking at Laptops for Parts, or a laptop like yours that may have internal problems, or a bad LCD screen.

As for guidance in removal and replacement, I have no links to give you for this exact model.

I can however link you to guides that are similar, and should work;


The LED light/Power Button/Speaker Cover is different in shape.
(Strip of plastic below the LCD screen, and above the Keyboard.
There are different names for the various models)


In case you wish to replace the LCD screen, lol!
Used to compare against the VGN-FW series, and to let you know, I know the VGN-FW series is a little different.

However after you have disassembled many laptops, you see that there is a simple specific pattern, for all laptops.

A) Don your ESD wrist strap, and connect it to a good ground source.
(Electro Static Discharge)
Average cost is around $3 to $6.

(I connect it's alligator clip to an unpainted surface, of the metal frame of an open, empty desktop computer case)

B) Lay a towel on a table. Make SURE it is static free. (Unless you have a workbench like I do, and static cover)

C) Laptop off, closed, and upside down on the towel, remove ALL power to the laptop.
Remove the AC adapter (Charger) and Battery.

D) Look on the bottom to see if there are arrows pointing to screw holes. Remove the ones indicated to remove the Keyboard, strip of plastic above the Keyboard, (If there are any), and Palm Rest Cover.

[ Use a multi-compartment container for the various screws you will remove.
If no multi-compartment container is available, substitute with a clean egg carton.
Label each egg holder for the area the screw/s come out of.

SOME screws look VERY similar to other screws.
DO NOT mix them up.

Make a record as you disassemble. Make notes, drawings, and use a digital camera, if available, or a video camera. (Use good lighting)
It's nice to have a record to refer back to, in case you are interrupted ]

E) Turn the laptop over to it's normal position, open the LCD screen all the way back.
Pop the strip of plastic above the Keyboard loose, then remove it.
Use CARE as there may be speaker wires, and LED light wires going to this strip. If you use a tool, (plastic Spud Tool?), do NOT damage the wires. These will have to be disconnected.

F) Remove the Keyboard. There should be 2 or 3 screws at the top of the Keyboard, holding it in place, OR there were screws you removed from underneath. (Bottom of laptop)

The Keyboard tilts up at a 45 degree angle, (Lift the back, or LCD screen side), then slides forward a little. (Towards LCD screen)
The Keyboard Cable is still attached, so do not try to remove it all the way yet.

The Keyboard is Not brought up to a 90 degree angle, when removing.
There are plastic tabs formed at the front of the Keyboard, which slide into the Palm Rest Cover. These can be broken off.

The Keyboard Cable does Not remove from the Keyboard. It removes from the motherboard.
The Keyboard Cable is a FFC. Flat Flex Cable.

It does not have a connector on the end of it. It's just a few wires encased in plastic, in a ribbon shaped flat cable. The ends of the wires have a small metal contact strip.

The connector on the motherboard is a ZIF connector.
Zero Insertion Force.
It is a rectangular shaped piece of plastic, that is composed of Two parts.

A smaller part that resembles a thin rail, at the top, and a thick block at the bottom.

The thinner part slides UP, (Towards the LCD screen),
it flips up. There are two different styles.

For the style that the thinner part slides up, it DOES NOT slide out!
It only slides up just a little, to unlock the Keyboard Cable. (1/8th inch approximately)

Then the Keyboard Cable slides out.
(Be SURE to note which way the Keyboard Cable goes in! Even if it is twisted, it MUST go back in the same position)

If you slide the ZIF connector completely apart, you will have broken it, and the repair is to replace the entire motherboard.

[ Also note which way all cables are routed through the laptop. They MUST go back in the same route, or you will not get the laptop back together ]

G) You will have to disconnect the Video Cable on the motherboard side, and the Wireless Module cables on the Bottom side of the laptop.

The Wireless Module wires are then carefully fed through the Palm Rest Cover, and laid aside. (They go up into the Display Assembly)

H) Perform one last check for any cables, then pop the Palm Rest Cover loose. (It has tabs formed on the outside edges, inside the cover. These snap into matching tabs on the Bottom Cover )

Remove the four screws from the bottom casing of the track ball. Carefully push the ball from the topside causing the case to come apart. Remove the ball and take an alcohol wipe and gently clean the area where the ball sits and the optical eye that the ball rest looks like a little window that is on the side of the area in which the ball rest in. Put ball back in the recess and put case back together. Replace screws and you should be good to go!

Can't remove cover to check power supply.

Remove the bottom base according to user manual, clips into the bottom, pinch them together with your finger under the base. Then remove hinge cover in back of panel by popping off the plastic cover with a flathead screwdriver. Then remove the 4 screws holding the metal plate. Under the plate are two screws. remove them and then carefully pop the case open. The 2 screws are the only hard fixed part holding the case together, plastic snaps hold the rest. Also remove the 4 screws in the back of the unit. Remember where everything goes, write itdown, there are several plugin modules you will need to remove when disasembling.

I can not remove the bottom stand off the Proscan TV Model 26LB30QD to mount on wall. Any suggestions?

I have this model (ProScan 26LB30QD) and recently removed the base. There are 4 phillips head screws on the rear panel of the TV just above the base. Remove them, pull the TV from the base, and replace the screws in case you need to use the base in the future. I suspect the problem others are having is that they only removed 2 of the screws.

I have a Presario 1700T notebook. It freezes after 5 minutes of usage. I think it's heat related. How do I disassemble the laptop to replace the heatsink/fan?

yes, to do that turn over your Laptop and let it relax on a well balance area then remove your battery slide out your hard drive and then use your appropriate Screwdriver and open the screws at the back then look to your long screw that comes out its meant for the Keyboard then turn over after loosing the screws then raise your keyboard a little about 45 degree then push it out at the back u will find a cord at the back so transparent be gentle when removing those part and target those place in case of puting them back then your palmrest pull-tab that is attached to the palm rest flex cable connector to remove it from the interface connector on the system board
Notice: Carefully separate the palm rest from the buttom case to avoid damage to the palm rest.then after making it open u see the microprocessor thermal cooling assembly then loosen the four captive screws that secure the processor then u have the thermal heat sink is with the processor remove it and make sure u add the cooling paste to ensure well cooling and replace as required u for open.

How to remove the keyboard to access the RAM memory slot

If you examine the area of the case above the keyboard (the small area between the keyboard and the screen hinges), you should see that it is a separate piece from the rest of the case. This small section of case should just pry off (be careful not to break it or the locking tabs). Once you have pried this off, you should see 2 or 3 screws holding the keyboard down. Remove these screws and the keyboard should come out. If you are just accessing the RAM, you shouldn't have to unplug the keyboard ribbon cable.
