On/Off Switch issue

Is there a lock feature on the on/off switch because the camera turns on randomly when I put it into the bag. I have to remove the battery each time I am finished taking pictures so the camera won't fire while stored. What a pain!

Card locked samsung s800

Hello Eilee,

Remove the memory card from your camera and check for a tiny switch on it. Make sure it is not set to "Lock". If it is, then switch it back to unlock.

However, if your memory card does not have the "Lock Feature" it could mean that your card is already malfunctioning. Try reformatting it first before buying a new one.

Note: You will loose ALL data from your SD card once you format it.

You can rate my answer if you appreciate it.

My camera says memory card locked. How do I unlock this feature

Remove the memory card from the camera, look along the one edge for a tiny switch, slide it towards the contacts to unlock the card. The switch that is in the furthest position from the contacts is in the locked position to prevent deletion of photographs, now! if the card is already in the unlocked position slide it back and forth to reset, if this fails replace the card.

How do I unlock the memory card?

SD cards have a tiny LOCK switch on the edge. If your camera is telling you that the card is locked you may need to turn off the camera, remove the card, slide the switch to the unlock position, then put it back in the camera.

My camera says my memory card is locked but the button on the side is not locked how do i retrieve my pictures i have a canon powershot a480

Issue: [Memory card locked] message appears on the screen.
Solution: Change the memory card lock switch to the normal setting

The SD card has a lock switch to prevent existing data from being erased. To record images or movies this switch must be in the normal (non lock) position. Different brands of SD memory cards may identify this switch differently. Regardless the procedure should be the same. Please remove the card from the camera and ensure that the switch is not in the locked position. sdcardlocked.jpg

You should be able to retrieve photos, but not writing or erasing if the switch is switched to write protect.

If it's not functioning correctly, the camera may need service at

Camera says card is locked but it's not!!!

You already know about the 'lock' switch on SD cards; did you know it doesnt actually lock the SD card by itself? It merely pushes a switch lever in the reader (in this case, your camera), that in turn tells the electronics to NOT write on the SD card.

So, if your SD cards are indeed working (check on a card reader), it would look like the lever in the camera that senses the position of the lock switch is jammed / bent. If you could pry into the card slot in the camera, and try to shake this lever with a long narrow object (a straightened paper clip, perhaps), that might yield good results.

Alternately, look up 'CHDK' on Google; it is an alternate OS that gives your Canon *lots* of other features. In your case, more importantly, it *requires* the SD card to be locked in use. Dont worry, with CHDK booted in, the camera will store pictures even when it sesnses the card is write-protected. So, it not only solves your problem, it gives you loads of extra features like RAW capability, time laps, remote operation and more, all for free.

Had my finepix f450 apart and now that its back together the on/off power switch wont work but it'll power on on cradle it. so it must be something i did putting it back together.any ideas

OK - so I've taken mine apart to see what may be causing this. The problem is most likely that you put the camera back together with the power switch set to off. In this position the metal slider that activates the power switch touches the fragile plastic tongue of the actual power switch and will sheer it off when the case is pressed together. However, the slider won't touch it when the camera power switch is moved to its 'on' position during re-assembly.There is no easy fix other than to either replace the module containing the switch or if you're a tinkerer de-solder and disassemble the switch and refashion the tongue that depresses the micro-switch by using maybe a piece of nylon from a small tie string (Ty-wrap) or alike. It's a fairly small switch, however. Finally, perhaps you could obtain a replacement switch from the manufacturer or an electronics supplier. By default, this switch will be on so removing it from the cradle should turn the camera on and inserting into the cradle should turn it off. So, if you can find a free or cheap cradle connector you could use it as a makeshift power switch or you can always bring the cradle along to turn it on - the camera's power timeout will then turn it off automatically ;) Hope this helps.

Card is locked

There is a small lock switch on the side of the memory card, slide it to the other position and try again.

1. Turn the camera off
2. take the memory card out
3. slide the lock slider to the other position
4. place the card back in to the camera
5. turn on the camera.

if the problem remains repeat steps 1 to 5.

if the problem still remains its now obvious the issue is not with the memory card, you may try another card on the camera if you wish.

The most likely cause for this issue is in the memory card reader of the camera. there is a small lever/switch on the side of the card reader that detects if the card is locked or unlocked. You would have to take the camera apart and pull the stuck lock "detector"/switch up so that it doesn't touch the the metal.

My DSE memory card says 'write protected'

Hi there, do this:
To fix this, remove the SD card from your camera. Look on the side and you will find a little switch. One end of the switch says locked the other end says unlocked. Move the switch from locked to unlocked. Replace it in your camera and turn it back on.
