Acer Extensa 5420 Disassembly Manual
Today I explain how to remove and replace the broken display hinge in an Acer Extensa 4620z laptop. This guide might work for some other Acer Extensa models too. In this particular case I’m replacing the right hinge. Before you start, turn off the computer and remove the battery. Insert a small flat head screwdriver under the hinge cover and lift it up. The hinge cover is a part of the keyboard cover. Remove the cover.
When the cover is removed you can see that the right display hinge is broken. The bottom part of the broken hinge is still connected to the base assembly and the top part is mounted inside the display. Remove one screw securing the display hinge to the bottom of the laptop.

If you are replacing only one hinge, remove only one screw. There are six screws securing the screen bezel. All six screws are hidden under rubber covers. You can remove screw covers with a sharp object. Glue screw covers somewhere on the bezel so you don’t lose them.
Start separating the bezel from the display cover with your fingers. Continue separating the bezel and finally remove it from the display assembly.
While removing the bezel, I dislocated the display latch. If you did so, put it back in place. Remove three screws securing the broken display hinge. Remove the bottom part of the broken hinge. Remove the top part. Install a new hinge into the display and secure it with screws. The broken display hinge has been replaced.
Assemble the laptop back together. Also, you can use this guide for removing and repolacing laptop screen and inverter board.
I don’t believe it! Just tonight – just like, 2 minutes ago – as I was closing my laptop for the night, that hinge JUST snapped. No, no smacking or abuse, just closing the screen for the night to set it down by my bed, and CRACK! It just snapped. It was the hinge on the left side of the screen, snapped off at the curve. I was afraid it would be the frame that broke and my mind started whirring away at my warranty coverage – nope, I think that expired in November.

So I’m hosed. Sad, too, because I just finished adding a webcam to finish off my maxed-out Extensa 4420. Fired up the computer again and brought myself back to this page (I commented a little over a month ago, above). Now, off to eBay to find a 4420/4620 hinge! I received a donated laptop with stripped screws on one hinge. The laptop had apparently fallen at least once, putting strain on the hinge.

Replacement screws were not available for anything close to a reasonable price, so I went to the local hardware store and found suitable substitutes that were slightly smaller and longer, but came with matching nuts. It doesn’t look pretty, but the laptop works, and I’m not going to complain about cosmetics. Some problems are dirt-simple to fix, and hinges are among them. A thousand thanks! I saw these pics and found my emachines D620 to be nearly identical. I thought my right hinge was beginning to break.
The screen bezel was seperating on that corner and there was lot’s of plastic popping sounds upon open/closure. I didn’t know there were screws under those pads. Turns out the screw just needed to be tightened (it was almost all the way out). The hinge wasn’t the problem at all. But if it wasn’t for your site I would have been calling Gateway or paying someone local to diagnose it. Instead I’ll be sending a donation your way.
Thanks again! the above procedure works for acer extensa 5620-6419. My question is this: will the entire upper assembly (all conected parts above the hinges-IE, lid,bezel, LCD frame), of an acer 4620 mount to to the hinges of a 5620-6419-using the webcam, mic, and 15.4″ lcd from a 5620-6419? To clarify:5620-6419 is to be fitted w/ lid, frame, bezel from a 4620. I noticed the above reference pics of the framework to the 4620 is a HELL OF A LOT better in structural integrity than my short-changed-china-built 5620-6419.

I’d like to replace this fan, but I can’t seem to figure out how to disassemble and access this fan (Furthermore finding a replacement fan). Do you, or anyone who may view this, have any suggestions/guides? I’d like to gift the laptop for Christmas as I’m getting a new one, but I’d like to resolve the cooling issue to help keep the laptop alive long enough. It took about 40 minutes to replace both hinges on my Extensa 4630Z. There are some differences so I will list them here. First, under the battery, there are 7 small screws that hold the keyboard cover in place.
Remove these before starting. When removing the rubber covers, only remove the 4 in the corners. The two by the latch assembly do not have screws under them. When removing the hinges, there are two screws under the keyboard cover on each side and two right above the hinge.
The third hole for a screw was removed when removing the bezel and keyboard cover. (from underneath) There are 4 small screws along each side of the display and one screw up at the very top that also have to be removed. Other than that, the steps above work perfectly. Thanks again. Thanks a ton. It give me some confidence that I can do this at home! I have acer extensa 4620z.
There are some cracks on top left edge of the screen casing. Otherwise the laptop works perfectly ok. Recently, I started seeing horizontals bands (mostly white) appearing on the screen. They move up/down and eventually cover entire screen. If I pinch the top left side of the screen casing it goes back to normal. Even if I adjust the screen position sometime it recovers.
Now I placed the paper clip to clamp the top-left screen casing edge as a temporary solution. Could you please tell me what could be issue? Should I try opening the screen casing? Thanks for the great instructions! I replaced a hinge on my Acer 4630Z, my first ever laptop repair.
For any future 4630Z owners, here are some differences from the 4620Z described in this article: 1. There are many more screws, including four along the side of the screen. Although there are 6 rubber pads on the screen bezel, only the 4 corner ones conceal screws. One of the screws holding the bottom (non-display) side of the hinge is not under the keyboard cover, it’s on the back of the case! (in the corner). The keyboard cover does not come out so easily. Something seems to be holding it in place near the lights and buttons.
Maybe I didn’t apply enough force, but it doesn’t matter for the left hinge – you can replace it without entirely removing the keyboard cover. Thanks greatly! Happy computer = happy me! Many months ago, the hinges on my 4420 were getting a little tight, so I put some oil on the hinge pins. That made it worse (the original white gease is better than oil). Recently, one hinge broke, probably from being too tight as a result of the oil.
Before installing new hinges, I bent the “wrap-around” flat steel parts very slightly, to loosen them a bit. This was done with a small screwdriver, placed into the gap at the end of each wrap-around, and then rotated slightly. I think this will help, but I won’t know for a few years.
