My camer's battery is not functioning, due to unproper used of non-rechargeable battery,the metal on the upper side of the cover on part of the battery container was burn,what is the best solutio

wrong site notify locksmith

1) change the batteries by new ones or recharge well the batteries
2) must be shure to use the o.k batteries type
3) clean the contacts batteries with contacts cleaner
4) poor contact between the cover camer and batteries contacts adjust it, and clean it
5) Wrong polarities with batteries inside.
6) memor card/slot/battery cover open

Here's a link to your radio's manual. Make sure the rechargeable batteries are able to accept a full charge. If they have been recharged more than a couple of hundred times, they may need to be replaced.

Pay attention to which jacks your are powering the radio through. The PWR and CHG jacks perform some similar, but very different functions.

The AC or DC adapter can be connected to the CHG jack when you wish listen to the radio (and recharge at the same time) ONLY when NiCad batteries are installed (or to simply recharge the NiCad batteries with the radio off). Recharging with the radio off will allow the batteries to recharge fastest (10 - 18 hrs).

As per the manual, you should not connect a power source to the CHG jack if using anything other than NiCad batteries in the radio, as they will heat up and could explode, instead connect to the PWR jack whenever using regular, non-rechargeable batteries.

pull the batteries out, slam them ******* a solid surface. put 'em in, let 'em charge. if that doesn't bring 'em back buy new bats.also, use a voltmeter to make sure the charger was getting voltage.
Good luck!

Make sure you are using rechargable batteries. Normal batteries are not strong enough. Try using either rechargable Lithium Ion batteries, or rechargable Nickel Metal Hydride (NiMH) batteries. These are much stronger and should give you a good battery life.

It could be due to the fact that some rechargeable batteries are slightly different shapes and the nobbly bit on the + end doesn't reach far enough in, as it is the case with Maplin AA batteries.
In my case I placed a small drop of solder with a soldering iron on the + nipple and now they reach into any device.

The BTR cover is covered the fuser. If you open the rear door, it is located at the upper part, behind the metallic rod. The problem is the cover is installed unproperly: Its metal piece is not touched against the metal piece of the machine, so the machine does not "smell" the BTR cover.

I decided to send you this from the Canon website to see if this helps: 
Issue: What are the specifications for batteries that I can use in my camera?
Solution: Recommended AA batteries for your camera.

What types of AA batteries can I use? Canon rechargeable (NiMH) batteries For the best results, we recommend using Canon rechargeable (NiMH) batteries. Rechargeable batteries provide the best performance and are the most economical choice.
The Canon Battery & Charger Kit includes a battery charger and four rechargeable AA-size NiMH (nickel metal hydride) batteries. The battery kit can be purchase from the Canon eStore.
AA alkaline batteries AA alkaline batteries such as those from Energizer or Duracell will provide the best performance for non-rechargeable batteries.

• ALL AA-based PowerShot digital cameras (including A Series and S5 IS / SX100 IS-type):"Never use manganese (non-alkaline) batteries."
• Since the performance of alkaline batteries may differ according to brand, the operating time of the batteries you purchase may not be as long as the batteries that came with the camera.

Precautions:

• Camera operating time may shorten at low temperatures when alkaline batteries are used. Also due to their specifications, alkaline batteries may expire faster than NiMH batteries. If you are using the camera in cold areas or for a long time, we recommend using Canon AA-size NiMH Battery Kit (a four piece set).
• While it is possible to use AA-size nickel-cadmium rechargeable batteries, performance is unreliable and their use is not recommended.
• Never mix unused and partially used batteries. Always load two or four (depending on camera model) fresh (or fully recharged) batteries at the same time.
• Be careful to load the batteries with their positive (+) and negative (-) ends in the right direction.
• Never mix batteries of different types or from different manufacturers. All batteries should be identical.
• Before inserting the batteries, wipe the battery terminals well with a dry cloth. Oil from ones skin or other dirt may cause a considerable reduction in the number of recordable images or reduced usage time.
• Battery performance deteriorates at low temperatures (especially with alkaline batteries). If you are using the camera in cold areas and batteries are running down faster than they should, you may be able to restore performance by placing batteries in an inner pocket to warm them up prior to use. But be careful that you don't put the batteries into a pocket together with a metal key chain or other metallic objects, as these objects may cause batteries to short-circuit.
• If you do not plan to use the camera for a long time, remove the batteries from the camera and store them in a safe place. Batteries may leak and damage the camera if left installed during prolonged periods of non-use.

WARNING
Never use damaged batteries or batteries whose outer seal is completely or partially missing or peeled off, as there is risk that such batteries may leak, overheat, or burst. Always check the seals on store-bought batteries before loading them, as some batteries may come with defective seals. Do not use batteries with defective seals.

I had the same problem and realised the camera is sensitive to the type of batteries you use.  I had put in non rechargable batteries.  Some brands seem to work and some don't, but rechargables are best, particularly the original sony batteries .  Try changing the batteries.

AA batteries are available in four basic varieties: Alkaline Nickel-Metal Hydride (NiMH) Nickel-Cadmium (NiCad) Photo Lithium (Li-FeS2) Alkaline and photo lithium are non-rechargeable, while NiMH and NiCad are rechargeable. Each has advantages and disadvantages. Non-Rechargeable vs. Rechargeable: Rechargeable batteries are desirable from an environmental standpoint because they are reusable. Self-discharge refers to the fact that batteries lose energy when unused and even when not in a camera or other device. Rechargeable batteries tend to have relatively high self-discharge rates, approximately 1-2% per day for nickel-based batteries. Non-rechargeable batteries generally have very long shelf lives and extremely slow self-discharge rates. This makes non-rechargeable batteries a better choice for infrequent usage. Non-rechargeable batteries are available fully charged in stores all over the world, which makes them a convenient choice for travelers or customers who have dead rechargeable batteries and no time to recharge. Photo Lithium Batteries (Li-FeS2) (non-rechargeable): Photo lithium batteries will yield the longest battery life of any AA battery, surpassing NiMH by 50-100% and surpassing alkaline by 100-500%, depending on the load. While they are more expensive than alkaline batteries, their additional energy capacity makes the cost the same or less per shot than alkaline batteries. Nickel-Metal Hydride Batteries (NiMH) (rechargeable): NiMH batteries are the lowest cost overall solution for users that take a lot of pictures (more than the equivalent of a roll of film per month) or use a lot of high-power features. The largest disadvantage to NiMH batteries is their fast self-discharge rate of 1-2% per day whether the batteries are in a camera or not. NOTE: NiMH batteries need to be completely charged and discharged a few times when new to achieve their full capacity. Rechargeable batteries will eventually fail. If you have been getting acceptable battery life and then see a decrease in life, either quickly or slowly over time, a worn-out battery may be the cause. Storing or charging the batteries in high temperature conditions will accelerate this potential failure. Alkaline Batteries (non-rechargeable): Although the cheapest and easiest to find, alkaline batteries yield the worst performance of all the chemistries in a digital camera. They lose capacity at high power drains and at low temperatures. Skiers and other winter outdoor enthusiasts may find them unsatisfactory. Alkaline batteries are frequently available in two types: High drain (ultra, titanium, maximum etc.) Regular The high drain versions are a premium product designed to operate better under heavy loads than the standard product. However, there is a trend of major brands to increase the performance of their standard battery to b
