Gateway M-7315U hinge

I disagree. The procedure is so easy no Service Manual is needed

1) Remove ALL power. Remove the AC adapter, and Battery.

2) Open the laptop.

The plastic frame in front of the LCD screen is the Display Bezel.
(Gateway? Believe they call it the LCD Panel Bezel)

Down in the BOTTOM corners, next to the Hinges, are screws to be removed. One in each bottom corner.

There are Screw Covers over these screws. The Screw Covers need to be removed.
Little round covers I believe to be made of plastic.
(Some models they are made of synthetic rubber)

I use a computer pick to Gently remove them.
Some use the tip of an X-Acto knife. I do not recommend this as there is a possibility of injury.
Perhaps a large darning needle. (Needle you sew with, but is Large in size)

Pick up at one edge of Screw Cover. Screw Covers are held on by a type of rubber cement.
I LIGHTLY stick them to the Display Bezel for safekeeping.

(Yes. They like to stick to the tool, your fingers, and it seems passing jets in the sky.
If you are careful with them, you should be able to reuse them.
If they do not stick anymore, use a toothpick, and apply a TINY dab of rubber cement to them/it )

Once the Screw Covers are removed use a No.1 Philips screwdriver, or equivalent Jewelers screwdriver; to remove the 2 screws.

The Display Bezel has TABS going around the exterior perimeter, of it's inside edges.
These Tabs snap into matching LATCHES on the Display Cover.

You can come from the Outside edge, where the Display Bezel meets the Display Cover, and use a thick guitar pick.

The guitar pick is wedged into the parting line, of where the Display Bezel meets the Display Cover.

Once a 'crack' is formed in-between the two, then the fingertips are used to gently start popping the bezel from the cover.

You slowly go along with your fingertips, and work along the top, then sides. By the time you have both sides almost loose, the Display Bezel usually pops off.

I like the flex method.
Come to the inside edge of the Display Bezel.
Where it meets the LCD screen. I suggest start on the Right side/Middle.

Use a fingertip, and lift up the inside edge of the Display Bezel up a little. Can't lift up at that spot? Move over. You are at a Tab/Latch.

With this spot lifted up a little, use the fingertip of the other hand, and slide under next to it.
Now use your fingertips as wedges, and pop the Display Bezel loose a little at a time.

I start at the Right side/Middle as stated. Left hand fingertips go DOWN the right side, Right hand fingertips go UP the right side.
Then I go across the Top, and down the Left side.

MOST of the time, as stated; the Display Bezel usually pops off when right side, and left side are most of the way popped loose.
NOT always though!

Sometimes you have to pop EACH and EVERY Tab/Latch loose.

Also; watch around the Hinge area/s.
Display Bezel can get hung up around them.
Go slow, and gently work the Display Bezel off, around the Hinge areas.

Display Bezel popped off, sit back; relax. You just did the hard part.
Wasn't so tough, huh?

This is what the Display Bezel looks like removed,

The MAIN view shown is a BACK view.
In the smaller views underneath, the 4th view from the Left, shows the FRONT view.

If you SET your mouse cursor in the middle of the Main view photo, the Zoom In feature is enabled.
You can CLICK on any of the smaller views, to make them appear as a Main view.

You can also see that the Hinge Covers, are an integral part of the Display Bezel. Shows you that when removing the Display Bezel, these Hinge Covers may need to be worked off of the Hinges.

Of course, may not; as I have previously stated.

The LCD screen is an Assembly. It is composed of layers.
These layers are kept in the factory set alignment, by a metal Screen Frame.
The Screen Frame resembles a picture frame.

There are THREE screws on each side of the Screen Frame.
These screws (Philips) go through metal Brackets, and hold the LCD screen/Screen Frame; to the Display Cover.

The Brackets are an integral part of the Hinges,

On EACH side, there is 1 screw towards the Top, 1 screw towards the Bottom/Middle, and 1 screw towards the Bottom.

Remove all 6 screws.

At the Top is the Webcam Cable. Unplug it from the Webcam Module.
(Cable pulls to LEFT side, facing laptop)

The TOP of the LCD screen is now tilted forward.
The Video Cable plugs into the Bottom side.

There should be a piece of clear Mylar tape, holding the Video Cable connector in place. Carefully peel it back, unplug the Video Cable from the LCD screen.

Remove the LCD screen.

Reverse steps to install new LCD screen.

Faulty hinges cannot be adjusted or tightened. If the the mounting screws are loose then these can be tightened.

Replacing a hinge, or both of them, isn't very tough.

Laptop hinges are generally made of low-cost metal alloys, or "pot metal yeah this may cause problem you can fix your broken hinges easily by spending little time ." Pot metal is not particularly durable, and over the course of a laptop's life cycle, repeated opening and closing of the computer's lid can cause wear that prevents the lid from staying in an open position. Hinges can also wear to the point that they break at the point of attachment, either on the lid or the computer's body.

Hinges are usually attached to the computer's frame via machine screws. In order to get the most life out of your computer's hinges, it is not a bad idea to perform a yearly inspection. Remove the hinge covers and check that the machine screws that secure the hinges are tightened fully. If screws are missing, contact the computer's manufacturer to order replacement screws; hinges missing screws are subjected to additional stress and can wear out faster if steps are not taken to replace the screw.
Lubrication of the hinge is possible, but not recommended; if the wrong type of lubricant is used, it could damage the computer's case or seep into the electrical components and further damage the computer. Consult a professional technician if you feel that your hinges require lubrication.

o Hinges can also be damaged when the computer is picked up by its lid, dropped from various heights or opened beyond the angle at which it should stop. In these situations, damage to the hinges may be of secondary concern, as component damage and data loss might have occurred. Depending on the amount of damage and warranty status, the computer may require complete replacement.

Laptop hinges are not indestructible, but their coverings and trim may show wear long before the hinges are actually in any danger of failure. Most laptops on the market include plastic hinge covers. The hinge covers can develop stress fractures from repeated wear; most of the time, this is not indicative of a hinge problem.
Some laptop hinges are housed within the bezel or trim of the computer's monitor or body. This, too, is generally made of plastic, and might develop stress cracks after a few years of use. Hinge covers and bezels are usually modular, and replacements are generally easy to find at low to moderate costs.

Repair

o Hinge problems can be mitigated with adjustments to the hinge's tension or additional hardware installation by the user. Brackets can be installed on the outer case to allow for hinge-like performance, or the screen can be mounted in a fixed position. If the screen is left permanently open, care should be taken to prevent damage to the screen and to prevent dust accumulation in the keyboard.
The lid and screen assembly can also be replaced, if the correct parts can be found. Replacement of the lid and screen can be cost-prohibitive, with parts and labor sometimes exceeding the cost of the computer.

My VX8350 broke on the right side too. Actually it cracked and the pieces, 2 if I remember correctly, kind of were just hanging there (in other words I did not loose any pieces of plastic). I did a very careful repair and it has held now for about 1.5 years with no problems and I've even dropped the phone about 4 times or more since the repair.

I used the CA glue, (cyanoacrylate glue or some know it as instant glue). But be careful so you do not glue your hands to the phone. Use VERY LITTLE glue cause it WILL wick into places you do not want it to go. Lastly, you have to index the metal piece in the hinge (use a hefty pair of tweezers) before gluing so the spring with work correctly and hold the phone either open or closed. If you error on the indexing, try to error on the side which will keep your phone tightly closed when closed and just barely short of fully open when open. That way you won't be catching the closed phone on things with it hanging partially open. It doesn' t cause any problems being just a tiny bit short of fully open.

So, open the phone, carefully tilt the two halves to expose the metal hinge, index the hinge, carefully rotate the two halves back to their proper position and carefully test the opening and closing action. If it's good, or good enough, then put the chunk(s) that broke loose back into position and while holding everything in place put a TINY bit of CA on one of the cracks. This should setup very quickly (hence the name instant glue) and if you can still remove your finger from the phone, do so, and put a tiny bit of CA on any other areas or other cracks where the glue did not wick to. Remember to use very little glue for this or you'll be sorry and your phone won't work. If you did this properly, your phone will now open and close like it did before...or very close to it. Good luck.

Are you talking about the door handle hinge? The door handle and hing do not need to be removed to remove the door panel. Remove the door handle bezel and the hole will be big enogh to come straight off with the door panel. See the picture below. This is the only diagram supplied in the service manual. It shows the bezel for the driver's door but it states that the rear door is similar. If you allready have the bezel off, or you are not talking about the door handle hinge, I don't know what you are talking about when you say "hinge thing"

If you have to ask "HOW" to disassemble your laptop, in order to remove and replace the hinge, then STOP, and take the computer to a qualified technician, who can safely make the repair.

hinges take alot of stress as they have to be quite tight to hold the screen in a certain position, alot of laptops can have over tightened hinges and cause splitting in the housing. Hinges can quite often come loose.
Make sure all screws are present around the hinge area and if you can tighten up your hinges.
If the hinges are badly damage you can buy replacments for a few $ off of ebay

I would try just using a little bit more force (not too much!) the bezel will have clips around it to keep it in place along with the screws under the rubber protectors. Also make sure that the bezel doesn't hook in to the hinge cover in any way, as this will prevent it from coming off properly. If it does then pop the hinge covers off before continuing.

take a small flat tip screwdriver under the plastic hinges near the screen and flip them up, the plastic hinge guards house the top bezel.

Order a front bezel and a hinge kit from any where on the internet for your model

There are screws on the front face cover of your display remove and replace remove the keyboard and there are 3 screws on each hinge to remove.
