My next door neighbour has an ipaq 1950 and recently she added a 256MB Sandisk SD card to keep her photos on. She is finding that while the card is in the slot, she is losing power, even when not actually using the ppc. For example, yesterday she said the power was 93% in the morning and by late afternoon, it was down to 54%!!!! If she takes the card out, there's no problem.
Any ideas as to why this bizarre behaviour could be happening?
