My camera is making a grinding noise before saying lens error restart camera, just wondering is therte a button i press to restart the camera. My camera is a canon ixus 80IS

Try these procedures.

It means turn it off and on again, but this probably won't help. You get this message with a lens error, problem with focussing/zooming or whatever. Usually means there is grit in the mechanism or it has been damaged by a knock.

Try one of these two fixes, if they dont work for you follow the link below for further troubleshooting.

Fix #1: Remove the batteries from the camera, wait a few minutes. Put a fresh set of batteries back in (preferably rechargeable NiMH 2500mah or better) and turn the camera on. If that didn't work, try pressing and holding the Function or OK button while turning the camera on.
Fix #2: If the camera's batteries ran down completely while the its lens was still open, the camera may show a lens error or not start properly when new batteries are installed. Remove the memory card and keep it removed, then install the new batteries. When you turn the camera on with the card removed it may come back to life, as this triggers a reset in some cameras. Error E30 (for older Canon's) means that you don't have a memory card installed, so turn it off, slip in the SD card and turn it on one last time

Hope you purchased an extended warranty. I've had two Cannon's with the dreaded lens error. Probably what happened was that while it was in your purse, somehow the power button got pressed. The camera powered up, tried to extend the lens, then stripped the gears or broke whatever mechanism extends the lens. The sad part is that if it's not under warranty, it probably not worth dumping $100.00 + into fixing it. Too bad, it's a nice 8mp camera with some pretty good reviews. I feel your pain.

Not without opening her up, What sort of noise? clicking or grinding.

If grinding its likely you have contaminated the lens with something, maybe dust or grit.

If its clicking then its most likely the lens has taken a hit and damaged a gear

Either way any change in noise from a lens isn't a good sign, sorry
If taking pictures is important on this trip I would certainly recommend getting this one attended to or finding a backup
best of luck

First off, see if Canon can help you. If not, the following blog outlines some repair options for a lens error. They won't work for all cases, but they're worth a try: http://camerarepair.blogspot.com/2007/12/fixing-lens-error-on-digital-camera.html

What do you do if it's a lens error?

nikon coolpix 4 lens error help!

It sound like a problem with the zooming mechanism (lens would not retract or extended) Press the power button on and hold it down while extending and twisting the telescopic zoom lens. It might fix your problem. In any case it could not make it worse Good luck!

You could try the Casio Tech Support team, but if as you suspet it is a matter of dirt- there is nothing to be done except replace the camera- the cost os shippin and examining the camera etc. will come close to its replacement.
