I was given an old laptop. Nothing electronically wrong with it. Just the display falling down over half way. I discovered that the thread piece from under the right cover which was pulled off was the problem.



Upon inspection, the screw nut (the end that plugs into the hole of the display) moved out the other end causing the thread to be disconnected. So I took the piece out and used two pliers to bang it back in place. It worked but slowly moved it's way back to the other end hole. Eventually it happened to the left piece.


The solution:



I banged both pieces from underneath to push the screw nut upwards.
Then I soldered the hole underneath to prevent that happening again and covered them in tape just incase the solder comes off.

Wonderful, it worked until the last minute of putting everything back together. I heard a clicking sound and the display fell back again. Yes it was the right piece again. The thread on the nut and the thread in the display hole broke.




Another solution:



I tried plastic tie wraps. Worked for a little bit but came out. Paper threads that eventually got grinded up. I tried a lot of things that didn't work. Someone mentioned super glue as a joke. I tried that and it worked until after a certain amount of turns and then it became loose again. Using nail varnish to remove the super glue I tried another type of super glue for bonding metal but that was just useless and didn't hold.



I am not an expert in glues and I am out of ideas on this one. The only solution I can think of is to temporarily use the display at a certain angle (at the time when the glue is placed in the hole) and slowly make turns or think twice about turning the display.


Any thoughts or glue and thread knowledgeable around here?

My dad's laptop looks about like that, except the screen was also falling off. The screen finally fell all the way off, so now he just hooks the laptop up to the television and uses the television as the monitor.

You might try epoxy glue...

I will try and locate that epoxy glue.

Well this series of Compaq Presario was on the value range. This one doesn't look like it suffered much abuse so I conclude it is just poor quality made out of the cheapest parts available.

Thread problems and falling displays is a sign of cheapness.

I misread: Fell all the way off?

Do you mean:

(1) The display came out of its casing
(2) Broke of its base
(3) Same problem as above on loosely falling over

The top half of the laptop, containing the screen, became unattached to the bottom half of the laptop, containing the keyboard, processor, etc. It started out being a very similar problem to yours, but eventually the whole dang thing just came off. It's still attached by the wires that feed the visual input to the screen, but as it is unattached, it won't stand, so my dad just feeds the visual input to the television.

I would have felt ashamed if my display fell loose and broke. If it happened to a new one and by contract I can't get a replacement I would go in panic mode. The display fell down a couple of times but fortunately it didn't break apart.

Next time I decide to use an installation on any machine I should always check. This one looked clean but I got suspicious when a constant connection was being made to an irc network. For the past week I fell foul to these trojans:

Scvhosts.exe
Mapi32.exe
Dhcpclient.exe

These rogues were directly replaced to services.
Took me ages to remove them from registry.

I didn't notice them because the first two appeared camouflaged and I thought the last one was a service before I installed the service packs.

Now everytime I adjust a display with the same fittings I get worried about the pressure on the joints wearing away.

Dad's not ashamed of the laptop, because it wasn't working at all, and the previous owner knew Dad likes to mess with broken computers, so he gave it to him for free. Dad made it work again, except for the screen falling off because there wasn't really anything he could do about that. It's actually a pretty fast little laptop, now; and it's kinda cool to have it on the television. No shame here.

Sorry for assuming. I thought it was brought from new. I am interested in broken hardware too. I was also given a laptop with a damaged display.




Upper right corner looks interlaced and I think some of the pixels fell behind. Just near the centre on the white side there is grit that looks like bits of dry mud. Not easily seen in the picture.




The exposed bit on the left was taped to a cover. The amount of scratches ontop is a sign of heavy abuse and with the crack on the display casing next to the exposed thread just shows that is has been dropped.




Sometimes this bottom part below the line flashes on small vibrations.




Pressure point. Not easily seen from the camera. When I opened this display a screw right from that side side fell out.

Here is what I think. First of all it has been abused and dropped. Secondly someone left an object on the keyboard and slammed the display shut causing it to bend the pixels on the top right from behind which forced the screw on the same line out. (Loose screw thread shown by the slight whiteness in the picture circled red above).

Inside the display frame on the unit there is white tape surrounding the top frame with a warning sign not to touch the tape. It has screws I think but I need to study more to know what I am doing before opening that up because I don't know if it opens the insides to the liquid. At the moment I am wondering if this sort of damage is repairable by unscrewing the display unit to get inside where the liquid is and push the unseen pixels inwards assuming they are still working.

When the display becomes non viewable because of the 2.5 GHz processor speed I'll have remote use for that with extra memory and a one gigabit card bus.
