Laptop LCD hinges

LCD hinges are to hold the display open while you do your work. It is NOT so you can lift the laptop. If you lift the unit by the LCD, the weight of the lower unit can flop open and damage the hinges and/or crack the LCD. This could also damage the LCD cable which will cost much money. So don't do it. If you're having trouble with a dark Display, look really close at the LCD. If you can see an image, the backlight or the LCD inverter has gone bad. You may be able to connect to an external monitor to complete what you're doing. If there is no image, the LCD may be bad or the video card could be bad. Some, in fact most, modern laptops only have one board. The motherboard. This means that the mother board must be replaced. Sorry. I didn't design it. The good news is that replacing the mother board is usually cheaper than buying a new laptop.

Instructions

1

Prepare the laptop for disassembly. Shut down the laptop completely, then wait a few minutes before removing the battery and unplugging the AC adapter. Turn the laptop over and lay it down on a flat surface so that the battery area is facing away from you and the hard drive is located at the bottom left corner.
2

Remove the hard drive cover. Remove the two screws located on the left side of the hard drive cover, then lift the cover to remove it completely from the unit.
3

Remove the memory cover. Unscrew the eight screws holding the memory board in place; this cover is located above the Gateway product sticker.
4

Disconnect the Wi-Fi adaptor. Remove the Wi-Fi cover by unscrewing the single screw holding the Wi-Fi adapter in place; this is located directly above the hard drive. Remove the two cables connecting the wireless card to the adapter and snap the card out of the holder.
5

Remove the memory modules. Gateway computers typically have two memory modules located in the center of the motherboard; lift these out gently with your fingers and set them aside.
6

Release the heat sink. Unscrew the four screws around the heat sink assembly; this unit is located to the left of the ventilation fan and is surrounded by a copper base. Carefully lift the heat sink and the cooling fan off the unit and unplug the cable attaching it.
7

Remove the CD/DVD drive. Unscrew the small screw located to the left of the CD/DVD drive, then push the drive out to remove it from the laptop completely.
8

Remove all screws around the base of the laptop. You will now be left with a total of 18 screws located around the edge of the base of the laptop, and in between the stickers and hardware components in the center. Remove all of these carefully and set aside in a safe place.
9

Prepare the cover for removal. Turn the laptop up on its edge so that the back of the laptop is facing you; you will see two screws on the hinges of the computer. Unscrew these and set them aside.
10

Remove the hinge cover. Open the laptop so that the screen is laying flat; use the flathead screwdriver to pry open the hinge cover and pull it off gently with your fingers.
11

Remove the keyboard. Lift up the keyboard and reach behind it to release the cable. You will need to tug gently on the cable to unhook it from the motherboard.
12

Unhook the LCD screen from the notebook. Unplug the Wi-Fi antenna cables located on the right side of the motherboard directly under the screen, then unplug the video cable located directly under the hinge cover. Remove the pair of screws located to the left and right of the LCD screen and gently lift the LCD screen off the notebook's base unit.
13

Remove the system board. Turn the base unit over and unscrew the five screws securing the motherboard to the base. Two of these are located near the hinge cover, and two are located beneath and to the right of the hard drive unit. The fifth is located a few inches below the top right edge of the laptop.
14

Disconnect the motherboard. Lift the system board, then unhook the cable connecting it to the base unit.

need to replace screen hinges


Tools Needed Fine Phillips screwdrivers, two sizes; a fine flathead screwdriver; a big heavy-duty set of locking pliers to get a grip on the barrel of the fine screwdrivers in two instances; screen wipes; a clean working surface in which you won't lose any screws.
Lesson Learned The method I should have used:
  • Shut down the computer.
  • Unplug AC power cable.
  • Use the sliding tab to remove the battery.
  • Close the LCD screen as best as you can. Flip the laptop upside down. Look along the left and right edges, close to the LCD hinges, for a screw on each side; mine were marked F10. Remove these two screws, which look fairly insubstantial.
  • Flip the laptop back over, as if you were going to be using it. Open the screen fully (180 degrees) so it's pointing up at your ceiling.
  • Spin the laptop around such that the right side is just off the edge of the table. There's a big plastic piece, actually two colors, occupying the last 2 1/2 inches (60 cm) of the laptop toward the hinges; mine has a small microphone hole near one end and a line of buttons for power, Web browser, etc.
  • Use your thumb from underneath to pry off the edge; the whole piece will begin to lift up. Work it out, being careful to note the two big semi-circular pieces that have to lip up around the laptop hinges. Set this piece carefully aside, and be nice to it -- it has a number of buttons.
  • You should be seeing a small green circuit board where all your buttons were. A single Phillips screw is in the middle; remove a surprisingly long screw and set it aside. GENTLY remove the green circuit board, by lifting up slowly from the right; a small silver plastic tab will keep the board from lifting up directly on the left.
  • Underneath, you should now see a relatively heavy wire with a connector coming from the left LCD hinge. Use the flathead screw driver to gently pry up one edge of the connector slightly, then the other edge. Pry a couple more times until it seems loose, then lift up by the cable.
  • Your LCD is now held by just one small wire bundle and whatever's left of your hinges. Go after the wire first.
  • Just above your keyboard, you should see two Phillips screws that actually hold the keyboard in. Remove this -- and don't be afraid, because they're very stubborn. I had to use the small Phillips screwdrivers and a locking wrench clamped on them to get enough of a grip to loosen these. Keep pushing down so you don't strip the screws. This was the hardest part of disassembly for me. Set the screws aside.
  • The keyboard slides up -- not in the sense of toward your face, but toward the laptop hinges. Slide it a short distance and you can then flip it upside down.
  • Follow that last wire coming from your LCD, which routes under the keyboard. On the 4652lmi (lets hope your model is somewhat similar), it's the wireless antenna. Two connectors hold it to the card; they pry up, but not particularly easily. Note which side goes to which; the white wire (aux) was on the right for mine.
  • When the connectors are loose, unroute the wire, freeing it up to the hinges.
  • This is probably a good time to slide the keyboard back into place and turn the screws a couple of times.
  • You should now have the LCD free, except for the remaining hinges themselves.
  • At the extreme edges of the corners, you'll see a triangular shaped piece of metal. That's the base of the hinge; a single screw on each now holds it in. Remove the screws. Lift the LCD straight up from the main body of the laptop. (Stuck? You -did- remove those screws from underneath in the first step, right? I didn't.)
  • Put the body of the laptop aside. You can now focus entirely on the LCD package itself.
  • At the top of the screen are two rubber caps, indented somewhat from the corners. Use your flat screw driver to scrape these away. No, you can't really reuse 'em, but at least the screws underneath are black. Leave the screws in place for a few moments.
  • Toward the bottom corners of the screen are a couple more covers made of mylar, like a balloon. Scrape them from the bottom edge with the screw driver. These you surely can't reuse.
  • Undo the four Phillips screws that you've now exposed.
  • Starting at one corner, -gently- slide the flathead screw driver into the bezel, the giant black plastic ring, around the LCD screen. Start to loosen the bezel, using fingers, screw drivers and prayer to work it loose without cracking it. If you get stuck on one direction, go in the other for a time. Once it's free, the bezel simply lifts straight up. Set it aside, and make sure you don't put anything on top of it.
  • Only do one hinge at a time. The hinges run along the edge of the LCD panel itself and wrap around at the top.
  • One heavier screw holds on the hinge at the bottom, on the innermost of two holes in the tab. Remove this screw.
  • Four smaller screws run along the edges of the hinge. Remove -- being careful not to slide 'em under the LCD, or drop 'em into your carpet. You may need to use two screwdrivers or a screwdriver and a thumb to lift them away from the LCD case.
  • The hinge should lift directly up. Set it aside, so you can show all your friends what a wonderful laptop technician you are later.
  • The new hinge should drop directly in. It won't. It's got to stay very close to the LCD panel, inside of a number of alignment tabs sticking up from the edge of the case. At the top of the case, a hole in the hinge part has to slide onto a small plastic part that sticks up. On the bottom, it has to slide into position on top of the two screw holes.
  • Try to put in one of the four side screws. They won't go. Use the small flathead screwdriver to gently, gently lift the LCD screen very slightly until you can put in the side screws.
  • Replace the screw on the bottom tab, with the screw on the inside hole.
  • Repeat for the other side of the LCD panel.
"Assembly is the reverse of disassembly." Yeah.
General Cautions
  • Make sure your antenna and LCD wires go through the designated holes near the hinge openings; don't pinch them when you put the bezel on.
  • The bezel will snap into place, seemingly by making lots of snapping noises. It probably won't be snapped into place in the right places. If one of your four LCD panel cover screws doesn't go in, you probably need to remove the screw completely and put pressure on the bezel again to re-snap it.
  • Remember the lower hinges have to drop down into the base of the laptop. Secure them with one screw on the top ... and, as your very last step, put in the less substantial screws from the bottom of the laptop.
  • The wireless card connectors are tough to put on. If you get them in position, you can use the back of a fine screwdriver to snap them into place.
  • Remember to open your screen 180 degrees before putting on the large plastic piece with the buttons and lights. Don't force the hinge cover parts through your wires; that would be, in technical terms, bad.
  • As the final step, close the laptop, flip it upside down, place the two remaining hinge screws from underneath.

How to remove the display on IBM T21 laptop


The laptop screen is secured to the laptop with screws at the hinges.
There are usually two screws per hinge. The LCD screen has one ribbon cable and possibly a power connector for the back lighting attached to the motherboard near the hinges. Disconnect these before you lift the LCD off the base, they are under the plastic panel above the function keys next to the hinges.

Compaq Presario Laptop (M2000 series) hinge


Hello Wendy names Nick and just done hinge work on the Presario V5000z and readin up on your problem my suggestion would be lookin on ebay or various sites for the hinge then go about replacing it.

Steps involved in replacing the hinge start with removing power and battery

Next come the more difficult step, removing all the screws fron the bottom of the unit (this is done to gain access to the wireless cables which run from the wifi card to the lcd display)

once the base is removed then you carefully use a flat head screw driver an near the top row of keys (while pressing a few of them down) you will see a few notches which you can pry off the top cover giving you access to the lcd screen connector and bracket anchoring screws.

hopefully you disconnected your wireless antenna leads by now, and also disconnected the lcd cable from the board.

now you have the lcd display free from the base, now to change the hinge.

under the lil rubber circle pads are screws holding the brazel to the front of the lcd, this should be removed to get access to the lcd itself and thus the hinge brackets.

remove replace carefully i might add. then do everything in reverse to get the system reassembled and there ya have it
hinge has been replaced

P.S. careful steps should always be taken to prevent shock damage to any computer system when working on internals, also mind bending and pincing cables since they can most times be easilly damaged
