Full Version: C760 With Loose Hinge
OESF Portables Forum > Everything Else > Archived Forums > Distros, Development, and Model Specific Forums > Model Specific Forums > Sharp Zaurus > Cxx0 Hardware
When I rotate the screen to portrait mode and fold it back over the keyboard the screen occasionally reverts to landscape then back to portrait. If I press down on the hinge it will stay in portrait mode.

I have more play in the hinge now than when I first got the device. Has anyone else had this problem and what, if anything, did you do to correct it?

I am a bit skeptical about dismantling my Z and I was hoping someone else has successfully tightened the hinge before I go and mess up a good thing.
The hinge on my C860 has a lot of play. I too was hoping to find out how to tighten the hinges.
While attempting to diagnose an intemittant backlight problem, I noticed that when I opened my C860 VERY slowly the screen would initially come on in portrait mode & then switch to landscape after the top was raised by a certain amount.

Look on the face of the hinge. The C860 has "SHARP" in raised letters & a square protrusion to the upper right of the "P". Now look at the space under the hinge where this protrusion would go when the lid is closed.

A little hole. And inside the hole you will find a microswitch (G). Take a paper clip, unbend it, now make an "L" at one end that will let you poke inside the hole.

Screen switches from landscape to portrait when the microswitch is triggered. Which is when the lid is closed down on the keyboard in either orientation. This is why pressing on the hinge causes the screen to return to portrait mode.

I have never taken that part of my C860 apart. If I had the problem, I would try to make a small "hook" to slip under the microswitch activator and attempt to "adjust" it upwards. But there are the obvious hazards to that operation, so do not take this as encouragement for your making the attempt if something bad happens (G).

Good Luck!
my hinge is ok though it does have some play but that must be like that by default as it's like brand new otherwise smile.gif

dunno if my question is related, but my backlight turns completely off if i rotate the screen to portrait AND i have the lowest brightness setting for backlight. never happens if it is at the second lowest or higher.

is that normal? ph34r.gif
