Display hinges

LCD-screen-connected-to-hinges

Display hinges connect two halves of a laptop – the display panel and base assembly. All regular laptops have two hinges located on the left and right sides of the display panel. Tablet PCs have one hinge-swivel located in the middle of the display.

The LCD screen mounts to the the screen mounting brackets which are permanently attached to the display hinges. There are two or more screws securing the LCD screen to each mounting bracket.

The display hinges are not repairable. If the hinge is broken or too loose to keep the display in an open position, you have to replace it with a new one.

In order to remove and replace hinges, you’ll have to disassemble both, the display panel and laptop base.

HINGE RELATED PROBLEMS

1. The laptop display feels loose. It will stay in the up position, but when you move the display it feels floppy.

First of all, try tightening screws securing both hinges to the laptop base and display cover. If tightening screws doesn’t help, apparently your hinges are worn out and will have to be replaced soon.

2. The display will not stat in the up position. When you open the display and leave it in the up position, it falls back.

Most likely one or both hinges are broken and have to be replaced. Even if only one hinge is broken, I would recomment replacing both hinges because the second one is worn out and could break too in the near future.

    Gateways seem to have a lot of hinge problems. The hinge area seems narrower than others. Mine was NV57.

    My question is: would lubrication have possibly prevented the hinge from breaking? Do you recommend lubing hinges? and with what?

    I did notice the hinge sort of binding, and taking a lot of force to close the lid. unless that was after the hinge had failed.

    I wanna thank you for make this kind of pages. I have a great doubt. I got a laptop of Gateway designers, model m, but I didn´t found too much info about them. I was trying to dismantle it, but I saw the inner lcd cable sticked to a foil or silvered paper and following one of the two connections, one of the cables was joined in a box that I don´t know what is it. I will apreciate if you can solve my doubts or make a blog about them.
    Tnx a lot.

    I just received my VAIO ea, i think problem 1. The laptop display feels loose. It will stay in the up position, but when you move the display it feels floppy. It like when i “poke” the laptop body, the screen will “sway”. Is this normal, or i just received a lemon? I have read some post about tighten the hinges, but it will apply pressure and wore it out. And another thing, i’m able to open my laptop lid with just one hand.

    Andy,

    does anyone know the part name / number for the hinge that is under the battery at the back on the LHS of the tosh satelite pro L20

    Go to eBay and search for satellite L20 hinge.
    Is it what you are looking for?

    Hi again.

    Just wanted to drop by and thank your for your help! I found my screen’s part number, it was exactly where you described. Also found a good seller on eBay from your link, thanks so much for that.

    The repair went swimmingly. I have a Laptop once again rather than a very small desktop. =D

    While I agree it’s not a beginner’s job, it’s not that difficult, it’s just time-consuming. If you’re prepared, with the correct screwdrivers, and are careful in taking note of what goes where, it’s rewarding and worthwhile.

    I’m not a beginner, but this is my first time working on a laptop. I was very apprehensive for a long time, but I shouldn’t have been. Your site here gave me the guides and assurance I needed to give it my first try. I can’t thank you enough, I think I may work on more notebooks in the future now.

    Repair took 4.5 hours, including occasional stops for breaks and for lunch. Awesome! =D

    I’m one happy camper – thank you again!

    Nope, I don’t sell anything on eBay. I’m just linking to eBay stores you can buy laptop stuff.

    Fantastic! Thanks so much, this is exactly what I need. I’ll give it a look tomorrow.

    I do have the service manual. It’s helpful, too bad it wasn’t helpful enough in this regard. I swear, HP makes me crazy. =)

    Nora,

    I have a dv9608nr with a broken left hinge. Finally getting around to buying the parts and replacing, I’d like to be able to close the laptop again and I now have the time. I’m not worried, I do a lot of hardware and some software work on desktops – this will be my first time on a laptop though.

    My problem is that when looking for the specific part I need, HP (damn them) lists different hinges for dual-lamp displays and single-lamp displays. I don’t know which I have, and have had no luck finding out from HP or my model-specific product specs – all they say is “17.0″ WXGA+ High-Definition BrightView Widescreen (1440 x 900)” which tells me as little as possible. Perhaps I’m missing something in my search.

    Is there any way I can tell which I have without cracking the bezel off of the display?

    I assume you already found the HP service manual for Pavilion dv9500/dv9600/dv9700 notebooks.
    On the page 20 you’ll find a list of all display assemblies used in this model. Some of them has dual lamp and others have single lamp. Each listed display assembly has a part number.

    Now you have to find which one is installed in your laptop. In most HP laptops the display assembly part number is located on a sticker glued to the video cable. You can access this sticker if you remove the speaker cover (keyboard bezel).

    After you find the display part number, you can figure out if your LCD has dual or single lamp.

    Go back to the service manual to the page 26. On this page you’ll fined part numbers for the hinges. Here’s a quote from the manual:

    Display Hinge Kits (include left and right display hinges)
    For use only with computer models with dual lamp display assemblies 432964-001
    For use only with computer models with single lamp display assemblies 432963-001

    Alternately, is HP just being a pain and there’s really no big difference? Could they be interchangeable?

    Thanks for any advice you can offer.

    les,

    How dificult is replacing the left hinge on an HP dv9000? HP’s replacement program ended 1 month prior to my hinge breaking, and they will do nothing to help.

    It depends on your skills. :)
    1. Remove the keyboard/speaker cover.
    2. Take apart the display panel and remove the LCD screen so you can access the hinges.
    Now you should be able to remove the broken hinge and replace it with a new one.

    How expensive is the hinge?

    You can find brand new hinges (both) for Pavilion dv9000 series for less than $20 on eBay.

    chris,

    the righthand hinge assembly on my toshiba satellite pro M10 has broken at what appears to me to be the riveted joint between the lower section of the hinge (that connects to the notebook frame) and the leaf directly under the moving hinge itself. is there any point in attempting to remove the hinge and drill out the sheared-off rivet (i’ve already drilled out the top half of the rivet), and then pop a new rivet in? or am chasing my tail here, with a repair that’s doomed to fail?

    You cannot repair this hinge, it has to be replaced. It’s not easy. You’ll have to remove the display panel and top cover to get access to the hinges.
    I would suggest replacing both hinges, because the second one can be weak and might break soon.

    thanks for the all the information you’ve made available here.

    i have read the proviso at the start of this section, saying that broken hinges have to be replaced, and can’t be repaired. i’d just like to check if that goes for my situation too: the righthand hinge assembly on my toshiba satellite pro M10 has broken at what appears to me to be the riveted joint between the lower section of the hinge (that connects to the notebook frame) and the leaf directly under the moving hinge itself. is there any point in attempting to remove the hinge and drill out the sheared-off rivet (i’ve already drilled out the top half of the rivet), and then pop a new rivet in? or am chasing my tail here, with a repair that’s doomed to fail?

    I have a Dell Inspiron 6000 with a bad hinge assembly (right side). The hinges themselves are in decent shape but I need the small, metal mounting block that the hinge mounts to inside the rim of the lid/screen frame. The one I have on the right side has stripped threads. It appears to be pot-metal or aluminum and measures
    roughly 1/2″ by 1/2″ and has three hole in the top, and 1 hole tapped in the side. Mine is stamped with a number 7 (4 on the left hinge.)Are you able to order/sell this mounting block? If needed, I can send photos. Thank You

    An FYI about laptop screen hinges:

    I recently learned a lot about taking apart and putting together Gateway (eMachines) MX7100-series laptops… the hard way. I’d bought an MX7118 mostly-new, refurbished with a short warranty. I noticed early on that the backlight would flicker or cut out entirely when the screen was at certain angles, but as my warranty provided replacement rather than repair, I decided to live with it. The problem got a little worse over time, but slowly. I’d also noticed that the plastic casing over the screen hinge screws had splintered off slightly on both sides, so that with the screen in the closed position I could see the silver-tone hinges and little brass screws, but that seemed entirely a cosmetic issue. (I’ve since learned that some degree of cracking in this area is very common on this model line and does NOT mean anything is necessarily wrong… but it IS a good idea to take advantage of the visibility afforded by the cracks to keep an eye on the condition of your hinges!)

    About a year after what passed for the warranty expired — when I’d ironically just finished clearing a particularly nasty Vundo infection off the laptop — I shut it down and, feeling a sense of completion, closed the lid. (I don’t generally close my laptops except when transporting them.) There was an ominous SNAP sound. I quickly lifted the lid to see if I’d somehow overlooked something on the keyboard or wristwrest and cracked my screen, but it was fine.

    The next day, however, when I powered the laptop up (freshly cleaned of that virus infestation which had taken about 2 weeks to clear completely) the screen wouldn’t light up at any angle. I did some research and saw that, while it required a moderate amount of skill, it might be possible for me to replace the backlight and/or inverter myself. I looked at some assembly guides and set about opening the screen assembly to see if I could figure out where the problem was and how hard it would be to fix.

    To my surprise, I found that the right-hand hinge had been soldered in place so that it would no longer turn — and that as a result, the metal bars attaching the inside of the screen assembly to the hinge at that side had sheared off due to the stress of having to BEND every time the screen angle had been adjusted! Apparently the original owner had had an issue with that hinge being loose, and when it was refurbished that problem was “fixed” by preventing the hinge from moving at all. The eventual shearing-off was inevitable, and probably would have happened sooner if I’d closed the screen more often.

    It appears that the frame snapping off suddenly damaged either the backlight, the inverter or both. I brought in a professional to look at the laptop and give me an estimate on how much it would cost to repair, since I felt getting the jammed hinge out was beyond my ability. (For people in central CT needing on-site repair, I highly recommend Computermedic.com and have no affiliation with Computer Medic other than as a customer, nor have I been compensated in any way for my recommendation.) The owner came out to look at my poor laptop, and concluded that, especially since it was likely the light and/or inverter would need to be replaced and require soldering (which they don’t do on-site) in addition to replacing the “Macgyvered” hinge, I would be better off just getting a compatible-model laptop second-hand and switching out the hard drives. Because he wasn’t able to do anything with the laptop that day, I wasn’t even charged for that consultation, though we expected the replacement laptop might need some repairs more minor than the one I had did. (Plus I’d have the old laptop for parts if any were needed.) I was fortunate to indeed find another Gateway MX7100 series laptop on eBay for well under the minimum potential cost of repairing the one with the bad hinge, and which required only a very simple repair which one of Computer Medic’s techs then handled in well under an hour, with no additional charge for after-hours (6pm) or same-day service.

    The moral of the story? When buying a refurbished computer, check for “repairs” like the one that disabled my laptop, preferably when the computer is still under warranty and ideally before loading too much of your own data and settings on it. Particularly if you have a Gateway M-series laptop and splintering of the screen’s plastic casing has made your hinges visible, check to make sure they turn properly. I’d never heard of a hinge being jammed in this way, deliberately or otherwise (nor had the folks at Computer Medic or, from what I could find via Google, anyone else) but if one bright bulb would do it, odds are someone else will think of it too… or the same person might be in a shop somewhere rigging some other laptop to fail after warranty as you read this.

    Sasha,

    Replacing hinges is not for beginners. If you decide to do it anyway, take good notes where all these screws go. The are many different screws in a laptop.

    I agree. On some laptops it’s easier because you don’t have to take apart the base. On other models (Satellite A45 for examle) you have to tear apart the whole laptop.

    Ryan,

    So when I insert the screw through the hinge and into the display it won’t tighten at all. The screws just pop out whenever I try to open/close the display. So my question is, what is the name of the piece on the display that I’m screwing into, and is that a replaceable piece?

    It depends on your laptop model. It’s possible that your screws goes into the display cover (top cover). Everything in a laptop is replaceable. The question is how much will it cost you.
    If you can provide the laptop name and model I might have a better answer for you.

    I’m having problems with my display as well, but I it’s not the hinges themselves. You know how you wrap the display itself around the hinge and then insert a screw to hold it all together? Well the part of the display that “receives” the screw is stripped. So when I insert the screw through the hinge and into the display it won’t tighten at all. The screws just pop out whenever I try to open/close the display. So my question is, what is the name of the piece on the display that I’m screwing into, and is that a replaceable piece?

    It’s not easy. In order to replace hinges on this laptop you’ll have to take the whole thing apart.

    My old Satellite A40 worked fine for me but now the screen doesn’t stay in the up position. When I move the screen up it fall down and I think it happens because the hinges are broken. The repair shop asked too much money for repair, I can buy a new laptop for that. I found new hinges on google but don’t know if I can change them myself at home. Can I? Someone changed hinges on Satellite A40 laptop?
