Hello, My Pentax W90 recently started acting up. Everytime I turn it on it takes two pictures and then locks up not being able to take any more pictures. A green square comes up in the middle and when I press any of the buttons nothing happens. I turn the camera off and on again and it does the same thing. I tried taking the battery out and the card and tried it again but it still does the same. I'm half tempted to throw it off a tall building. Please help. Oscar

What you need to do is take out the card, and on the side of it there should be a little gray thing which can slide up and down. It needs to be slid all the way up. I hope this helps!!

SOURCE: Unlock card

If the card is locked, you could the steps below:

- Turn off camera
- Remove memory card
- Take a look on the switch of the memory card itself
* If it's at the TOP = card is UNLOCKED
* If it's at the BOTTOM = card is LOCKED

- So, you just have to make sure that the switch is at the top
for the memory card to be UNLOCKED

After doing that, you just have to put back the memory card to your camera and turn on the camera. Try to check if this works.

Try taking the card out of the camera and clicking the side of the card - there may be a little gap on one side of the card or a small button that you can slide up and down and then reinsert your card.
