BATTERY dead. how to charge?

Very likely dead.
Did you take out the battery and memory card before drying. Also it should dry for a week.
If you are lucky its just the battery thats dead. So try to borrow a battery from a friend who has the same camera.

The battery is dead need to purchase new battery or the battery is not accepting charge when you plug in your power cord. If you can borrow your friend's battery to check your psp. If still the same, the problem would be the motherboard itself and need for replacement or repair.

it can take up to about 3hours to charge, it it seems as if its not charging you may have to replace the battery, but to be sure do a battery test by borrowing a friend's battery and trying it in your phone see if it works and see if it will charge

I'm working on the premise that SMTH stands for something.

If its had water in it, and the battery wasn't removed immediatley and not replaced until the camera was thoroughly dried out, then its probably dead. Water and the electrical charge from the battery will short out the delicate circuits in the camera.

Its probably too late now, but you could remove the battery and put it in a warm dry place (airing cupboard) for a couple of days, then try it again.

If you have a friend who uses the same battery try one of yours in their camera to see if it works properly. Alternatively, try the opposite and borrow a known good battery from a friend and try it in your camera.

You either have a major problem in your camera, a coincidence of two dead batteries or a broken charger. Make sure all you connections are clean. Just a simple piece of printer paper rubbed over the battery contacts is enough to clean them. Ensure the charger connections are clean and even the connections in the camera. Check the lights on your charger. Is there any indication the battery is flat to start with and any indication of when it's charged? Usually a red light means the battery is charging and that light going out or turning green means it's charged. The battery shouldn't have to be on all night. Usually it should take maybe an hour or 2.

Finally, how long have you had your batteries and are they Li Ion or NIMH. Nicads are no good for digital cameras. They can develop memory problems. So if they are Li-ion or Nimh ensure you are using the correct type charger for those batteries

Remove the battery and make sure the contacts are clean. It might even be sufficient (for a while) to just remove the battery and put it back in. If that works, you should clean the contacts.

The next step is to try another battery. If you can borrow one from a friend with the same model, do so. If that charges, your battery is bad. If it doesn't charge, ask your friend to try charging your battery in the other camera. If it charges, then try borrowing the AC adapter. That will help isolate the problem without spending money. If it goes this far, post a response on your results.

The best thing to transfer pics from camera to computer is not to transfer directly. Take out the memory card and load the pic through card reader. This is even faster and safer for your camera getting the virus. perhaps your camera is now virus infection but I just hope it's not. try it, that's what am doing.

First you need a connection or a card reader and it should appear as anremoveable drive in MY COMPUTER
and open it as if it is a folder and block copy paste

the notebook cannot be charged without the charger and further more if it is not working properly ,try get a new one and it will work.i also recommend that you show it to a technician .

Heat and batteries - maybe Try another battery Remove camera software from computer and put the disk in the box. Plug camera in switch it on and set it to upload mode Windows should find it as a new drive or[XP/2000/ME] will put up camera/scanner wizard.
