Re: Internal lens Cover
Try blowing lots of compressed air around the open lens shutter to clean the mechanism. Or use a hair dryer for a few seconds (don't want to heat up the camera). Also with the lens barrel extended and pointed downward, tap the lens barrel with a pencil while you extend and retract the lens by powering the camera on and off. A grain of sand in the mechanism is usually the culprit, and you want to try to dislodge it.
You can open it up, but only as a very last resort. The above procedures usually work if you try them enough. But for those particularly nasty stuck mechanisms, here's an example repair on a Canon Powershot A400 (do this at your own risk, and it will void your warranty):

Not sure about the reference to 'right-handed' lens cover - most of them have a spring clip for the filter threads. To get a lens cap, just look on eBay for one that has the same internal diameter as the filter threads on the lens - this is usually marked on the lens, as in 49mm, 52mm etc.
Sir, Respectfully please first check if there is a modem in the desktop PC since the dimension 3100 is not pre-equipped with a modem. you have to attach an internal modem manually on one or more PCI slots on the mother board. the process is given here....
Turn off the computer. Unplug
the power cord from the electrical outlet. Disconnect the power cord,
attached peripheral devices and any other cables.
Locate the cover release latch
on top of the computer, near the back. Place the computer on its side,
with the removable cover facing upwards. Slide the cover release latch
back and lift the removable cover off of the computer. Set the removable
Locate the PCI and PCI Express
slots near the bottom of the system board. Select a slot that
corresponds with your internal modem card. Open the card retention door
on the back of the computer and remove the filler bracket for the card
slot you will be using.
Place the internal modem card
into the appropriate card slot and press it firmly into place. Close the
card retention door. Replace the removable cover and return the
computer to an upright position.
Connect one end of the telephone
cord into the LINE port on your internal modem card; plug the remaining
end into a telephone jack. If desired, connect a telephone to the
internal modem card via the PHONE port.
Reconnect the power cord and all
previously disconnected cables. Plug the power cord into an available
electrical outlet. Turn on the computer. If any installation software
came packaged with the internal modem card, run the program and follow
the onscreen directions. Your internal modem is now ready for use.
A stuck lens cover is a fairly common problem, but it is normally easy to fix. A single grain of sand jamming the cover mechanism is normally the culprit, and you want to try to dislodge it: 1) Try blowing compressed air around the lens cover to clean the mechanism. Or use a hair dryer for a few seconds (don't want to heat up the camera). Use no heat mode if possible. 2) Gently slide a thin strip of paper between the lens cover shutters and the outer support ring. Work it around 360 degres to clear out any debris that may be in there. 3) With the lens barrel extended and pointed downward, tap the lens barrel with a pencil while you extend and retract the lens by powering the camera on and off. Repeat the above three steps several times. If repeated tries don't work (keeping in mind that it usually does), it then may be necessary to open the lens barrel to access the lens cover mechanism.
You can open the lens barrel up to fiix the covers, but only as a very last resort. The above procedures normally work if you try them enough. But for those particularly nasty stuck mechanisms, here's an example repair on a Canon Powershot A400 (do this at your own risk, and it will void your warranty):
I'm guessing that the lens is stuck. Either the cover refuses to open because something is wedged in or a mechanical malfunction. The camera won't work if the lens does not come out a bit. Take a look at the lens and examine why the cover doesn't open up. If it is a mechanical malfunction (meaning internal problem), might as well have it fixed. Be careful and keep your fingers off the lens. You may touch the cover but hands off the lens. Hope this helps.
NO Super glue this can be fixed pretty easily to get fixed. most local shops will not charge you to much to fix it maybe 15 to 20 at the most i figure. or you can remove the lens cover by putting a very small flat head screw driver on the side of the lens and with the camera off pull away from the camera and it should just pop off. Superglue if you get it on the lens will rune the whole thing. Just tiring to help out . I repair lens shutters all the time they are just mechanical parts nothing really special about them.
