Need advise, my 1Ds has been acting funny of late and I fear it's more than a battery issue. I put a fully charged battery into the camera the other day and at first it read fully charged and then bam....nothing, battery read empty, so I went to B&H and got a third party battery for my 1Ds and charged it fully first and got the same exact response, so before I return it to KEH for repair is there anything I can or should do to try and fix the problem??

Got similar problem with my 1Dmk2. It eats the batteries even when turned off. I have to check it, but have not enough time (I allways charge batteries before shoot, so it doesn't matter that much to me). Hope that it is not some problem with 1Dmk2 processor taking wrong battery power assumptions.
