Hey everyone,

Only had my 50d a few months and It just won't turn on, I obviously charged the battery checked the door was closed properly removed all lenses, CF cards and tried everything.

Its just not responding at all.

Any one had this problem at all?

I am very worried.

Cheers
 
Probably a silly question, but have checked that the battery is actually taking a charge, in case the problem lies with that or the charger?
 
Unless you have a spare battery to try, there isn't much point going any further.

I can try one tomorrow at work we have several. Just seems a bit odd if the battery is indicating charge in the charger but not working in the camera?

I have a nikon battery that does the same, appears to take a charge normally, but due an accidental bashing it got, it doesn't actually work in the camera, so yes, its perfectly feasible. However, I think you might be looking at a repair if the spares at work have similar results. :(
 
Thanks for the input guys anyway, I will go to work tomorrow check where the problem lyes I really hope its in the battery don't want to be without my camera, got three years warranty so can get the to replace my battery I hope!
 
just a thought are all the contacts clean

Yep there pretty much perfect, I don't get it was working fine when I downloaded some images onto my mac the other day, then charged the battery before I put it away. Put it in and when Ive come to play with it today after getting a new redsnapper tripod it just did not work, BUT I did have to charge it again which is odd?
 
Sounds from your last post there that it is the battery.

Like you said try at work tomorrow and you will prob find thats the prob

sounds like a battery prob, i can charge mine and not ust it for weeks but holds its charge

as you said try it tomorrow at work with the other batteries:thumbs:

Its just strange how If i plug it into my charger now it flashes for a few seconds then goes red. I can pray its the battery !!!

Sorry to say batteries arent normally covered by warranty, although you might be lucky, has it had a hard life?

Basically I have had the camera since October and I look after all my kit, I could get away with showing it someone as a brand new camera, So I dont really get it.

By hard life I mean lots of action/re-charging etc, do you always let it get absolutely flat before re-charging?

Have you made sure you've taken out the internal button shaped battery that keeps the settings/system time? It should be inside the normal battery compartment but be harder to remove.
It's worth a try!

I never let it get flat really before charging I like to be ready and not run on a low battery. I can't say how many times I have charged it but less than 100 easy.

That could be the problem, batteries should be allowed to go flat else they get a memory and wont take full charge.

very good point hence why alot of people have two or more batteries.

I always try to let my batteries go flat, stems from battery drills(I am carpenter)
 
Does the top panel LCD work, not sure about Canons but on Nikons when you pu the battery in, the top panel LCD will show the number of remaining frames left. Good luck

My laptop ones do :)

But you should be able to recondition them easily by charging and discharging a few times.

Problem with laptops is that people rarely use the battery power, they plug the AC adapter in and leave it in, then when they want to use the battery it only lasts 1/2 hour.

I've had my current laptop for 3 years almost, and the battery still lasts 3.5 hours. I basically use the battery power until it warns me that it's getting low then plug it in, so it's always being used, discharged and charged.

I got my wife a second battery for her Canon Ixus and it did the same as this, returned battery for exchange and the new one went through the full charging cycle and works fine.
Lets hope yours is the same problem :thumbs:

Lithium batteries should not be drained and allowed to go flat....

This can degrade the performance significantly...

You should keep them topped up...

Heat is the thing that kills these batteries..

This is correct.


Lithium batteries don’t suffer memory effect, but they display similar symptoms with age and heat is the major contributor to premature aging. (Age is measured in charge/discharge cycles)
It is also true that you shouldn’t fully discharge a lithium batteries but this isn’t something that a consumer needs to worry about in general as this is generally covered by the manufactures. The camera will show that the battery is flat before it drains to a state where it will harm the battery, hence why there is enough charge to display the flat battery screen. (This is why windows is programmed to turn off at around 7-10% battery and this figure shouldn’t be move to a lower figure.)

Quite a few battery drills that i've seen still aren’t lithium powered though so should be fully drained.

Tried several batteries this morning and no luck, Rang up place where i bought the camera they send to send it canon, so I rang up H . Lehmanns and they have told me its probably a faulty ICC? switch or something and they will repair and and clean my sensor and viewfinder while it is there.

They are closed until the 4th now so there is no point sending it until then, looks like I am without a camera for new year and christmas great.

Unlucky mate. Especially with all the "look at my new camera i got for xmas" threads.
 
All batteries suffer from memory effects.
NiMH and NiCd show them a lot more than Lithium (either ion or polymer).
Li-ion cells, which is what you have in these cases, are not very prone to the half-charge syndrome which can effect the other types, but it is still there. You loose maybe a couple of percent at most.
What needs to be taken care of with Lithiums is not to discharge them past their cell-potential, as this can lead to the cell contents starting to dissociate, and generates a lot of heat (some can even self-combust).

With lithium batteries, the main problem is cells getting out of sync with each other. The batteries/cells need to be ballanced to bring the voltages in-line, which is where most laptops will suffer
 
Have you tried removing the lens?
As the system is currently not usable, do this with one hatch at a time, try to manually push the hatch contact in, it might just be loose, and enough to bring the camera back to life.

If it is the cell, although they are not usually covered by a warranty, as they are considered consumables, I would argue that 3 months is not a suitable lifetime for the cell.
