I have a Pentax Optio M85 which no longer charges anymore. I only have a USB connection and if I try connecting it to a laptop or PC a message appear on screen (not camera) that the USB is drawing too much power.
The blue light on the camera alights to suggest the USB connection is working yet it doesn't re-charge. At the moment my camera is dead and I can't use it!
Has anybody come across this issue before?
Thanks.
I don't have this camera, so in all honesty this is a flat out guess...
Although anything with a USB connection is 5 volts, each USB port on your PC is limited to a maximum power transmission of 500ma (one-half amp). Based on the message you see, this camera requires a greater amount of power. This is not all that unusual these days. Many phones and certainly nearly every tablet currently being sold requires more than 500ma. I would suggest borrowing a higher capacity charger from someone with the same style USB connector. Look at the label to see if the power supply output is 1A (one amp) or greater.
My additional concern is if the camera's battery has a short. When you plug in the borrowed charger, keep a finger on it to monitor its temperature. It will heat up, but if it gets even remotely uncomfortable (~50C/120F), remove power immediately.
