| On my HP 728, I have a spreading crack starting from the left hinge and traveling about 1/2" up the left side of the screen, and about 1/4" from the screen itself.
So far, the screen and hinge are unaffected. What would folks suggest using to prevent the crack from spreading further?
Ideally, a piece of plastic could be glued over the crack, but that would prevent the case from closing fully, I think.

| Ah, you've cracked the case, Holmes.
I always find superglue inside the existing crack does the job. |

| I've always disassembled the parts completely, then used an epoxy made for plastics on the inside of the component. More than once it required me to put a clamp or wad of rubber bands around the piece to hold the crack shut until the epoxy dried. Sometimes, I will heat up the crack using a solder gun to melt the plastic on the inside to help fuse the pieces together.
A lot of work I know, but I've always felt that if it is worth doing, it is worth doing right. |

| Many thanks for your quick posts. I don't think I'm capable of taking off the screen, and heating up the crack when it's so close to the screen might cause more problems. Were I to simply use a glue, toothpick, and an attempt to fill the crack by hand, which is the best recommendation, epoxy or super glue?
Thanks again,
Jake

| Do be careful of the type of glue you choose. i had mine glued with the wrong type and the plastic around the glued area became brittle, and caused hell.
I ended having to purchase a loose part off ebay and now it's saveD my day. but 7USD poorer. LOL.
And I think the crack started appearing due to the hinge mechanism getting tighter with age, so Now i have to hold that part with finger and thumb when opening and closing the screen. Though a bit of a hassle, but just to make sure the stress exerted on that part (by the hardened hinge) is not so much.
P/S: The part which I bought came with the hinge mechanism attached, but the hinge was stiff and wouldn't even budge using two pairs of pliers, so I have to reuse the old hinge.

| I'm thinking about using JB Weld Plasticweld Quick Set Epoxy. That seemed to have tested well, and it has some expansion qualities that might fill that crack.
I think royalnyl is right--age stiffens the hinge and makes the case work harder.

| A little petroleum jelly applied periodically when the hinge starts to stiffen might reduce that effect, though. |

| Yet another vital use for an age-old lubricant!
