E18 - 'Whack' Repair
--------------------------------------------------------------------------------
It could work for you! Scroll down this page for related postings. If you have no way out, your Canon warranty is expired and you don't want to take your camera apart, try this:
Smack-whack the camera several times with your open palm on the USB port side until the zoom lens engages, goes back in and starts working again.
I pressing the extended the lens gently may work for the short trem as well.

Re: E18 FIX !!!!!
My E18 problem is fixed. I didn't do the high-tech fix as described above, my fix was very low-tech. I gave it a good whack. I know, not for the faint of heart. I have a 3-year-old PowerShot S20, which is out of warranty, and I figured $200 to fix a problem that might happen again would be better spent on a new camera. I saw the whacking idea on this page
http://www.camerareview.com/templates/digital_reviews.cfm?digital_id=87 and since that person had my exact same problem with the same camera, I figured why not?
My camera's lens was stuck in the extended position after the battery died and the camera turned off. After a fresh battery I turned it on, the lens made 2 small adjustments, then I heard the faintest whirring noise. During the whirring noise I smacked the camera with my open palm on the USB port side. It took 2 whacks, but then it sounded like the lens engaged. I turned it off and the lens slid right back in. So far, so good, but I hope I didn't whack anything else out of alignment.

Re: E18 FIX !!!!!
Yesterday I experienced this E18 error. So I googled and found this site.. And sort of gave up the whole thing..
But then I did like the Russian astronaut did in the movie 'Armageddon'. So I gave the camera (a S20, not S100) a solid whack on the side where the usb connector is located.. and.. bzz.. the lens went back in.. and the camera works all fine now..
(The e18 came after a power off due to bad battery status (so low that the cam didn't have time to shutdown normally and the lens was still visible)

Re: E18 FIX !!!!!
Thanks for posting the 'whack' technique! After a few whacks, my S110 no longer dies with the E18 error.

Re: E18 FIX !!!!!
Amazing! I used the whack technique just now on my 3 1/2 year old Powershot S100...I was about to give up on it.
Lo and behold, after 5 or six good whacks (on the USB side of the camera), there was noise coming from my camera, and the lens opened.
Now it's working fine again! I don't know for how long, but I'll whack it whenever it stops working.
