Camera will not power on
Even after installing a fully-charged battery camera will not power on .
Remove the battery and gently wipe the electrical point of contact between the battery and the camera. This should be done with a microfiber cloth or any material that resembles the texture of very soft satin. Don't use any cleaning solutions while wiping. If any residue on the electrical point of contact is not removed, repeat this process with cleaning solution intended for electronic products.
Before anything else, check the expiration date of the battery. Even rechargeable batteries have an expiration. When rechargeable batteries expire they should be disposed of properly. Your city should be able to assist you in properly disposing of batteries. There are also some hardware stores that offer battery disposal services for the general public.
If the camera cannot be turned on or the display does not light up, plug the camera into the AC adapter and let it charge. You might have a dead battery and may have to replace it.
Make sure the battery is neither too hot or too cold. If the battery is extremely hot or cold it will affect the camera's ability to power on. If the inside of the camera is too hot, leave the camera off and let cool down and try again at a later time.
Camera does not register on computer
"When you connect your camera to your computer via Micro-USB, it won't show up on the computer."
Bad Micro-USB port
A different way to address this issue is through forced-air. Since this is an electronic product, avoid letting any form of moisture come into contact with the camera; Moreover, the best way to blow air into this Micro-USB port would be through canned air. Make sure not to hold the can upside down or shake while in use in order to prevent the liquid used to make the compressed air from entering the Micro-USB port You can even use a compressor. You can blow air in the opening through your mouth, but you should use caution when doing so to avoid placing moisture in the Micro-USB port.
Bad Micro-USB cable
Use some of the same techniques described in the "clean battery" section above to clean your Micro-USB cable. Some of the points of contact on the Micro-USB cable can be wiped in a similar fashion. The larger end of the cable (USB end) has smooth points of contact located within the rectangular slot used to connect your cable to a computer, make sure this surface is free from any residue. The smaller (Micro end) should be cleaned with forced air, this should allow the cable to communicate with a computer once connected.
When the above steps do not solve your trouble, trying using a different Micro-USB, now readily available at most department stores, convenient stores, and gas stations.
Flash does not open
No matter what you do, you can't get your flash to open.
First, check to make sure your camera is not set on "No flash" mode. It is common to forget that the camera is set to not use flash.
If your camera is set to use flash, but the flash still won't pop up or has a delayed pop-up, you may have dirty hinges. This issue is a frequent situation for avid photographers, but it is not out of the ordinary. Remember to use non-metal materials to clean the hinges. Many household items like cotton swabs or toothpicks will suffice.
Make sure the camera is off. After the camera is off, remove any residue that might be blocking the hinge/swivel area of the flash. Press the button to take a picture and see if the flash pops up like normal.
Next, try to take the toothpick or whatever tool you will be using and remove any hardened residue that might be preventing the flash from opening.
