SD300 power problems

[keelaw]

I have bought an SD300 about a month ago and whilst its a great camera, i have been having power problems.

Before it would intermittently power down, which i assumed to be down to the power saving function, but now it is powering down as soon as I turn it on and it won't stay on.

The battery is fully charged and the only way I can get it to stay on is if I keep my finger on the on/off button.

Anyone else been having similar problems and any news on fixing it?

The other side to my problem is that I bought the camera in Bangkok and they only gave me a warranty for Australia and NZ. I think they should have given me an international warranty. I am now in Hong Kong and I wonder if customer services in HK will be able to look at my camera under warranty.

Again anyone had any experiences of using warranties in foreign countries?

I'm also having problems with my Powershot A70. I put in fresh batteries and can only leave the camera on for about 10 seconds before I get a battery warning light, whether I take pictures or not. It will stay on nearly indefinately while in picture review mode, but as soon as I switch to picture-taking mode, it thinks the batteries are dead, which they most certainly are not.
