Strange Behaviour

I was taking some still life photos last night and the camera kept switching itself off. I had set the auto-power off to 3min however this was happening in less than a minute.
I have reset the value to 5 min and tonight I noticed that shutter speed indicator blanks out after 6 sec and the camera powers off in about 20 sec. The camera is set to AV, aperture at F8, ISO Auto (100-3200) and I am testing this under indoor lighting. The only thing out of the ordinary is that I tried the (non Pentax)IR remote, which did not seem to work properly and then I used the wired remote, the problem manifests itself tonight without any remote attached. I fully charged the battery before use tonight. The camera is only 2 months old and has taken about 1600 photos. When I half press the shutter, the camera returns to normal but then the problen returns.
Is this a fault or caused by the interaction of another setting.
Thanks

You don't say which camera you have . So first question is did you take it out of remote mode? I know that with the DL I have to set it for remote and then back when done. I haven't tried the remote with my K-30 so I'm not sure about it.

I have the K30 with the 18-55 WR lens.
I recharged the battery (it was nearly fully charged anyway) and have done a few more tests after switching auto power off to OFF.
TV mode - The aperture display goes blank after about 8 seconds
AV mode - The shutter display goes blank after about 8 seconds.
TAV mode - everything flashes and the IOS says AUTO then shutter and aperture flash then camera shuts down after 30sec.
The anti shake starts off green then changes to white and shows ON.
Also I cannot see any info in the viewfinder unless I half depress the shutter.
I had set the still life shot in the kitchen but I was not aware of any humidity.
The only other thing was to set the camera on a tripod. I was not aware of overtightening the screw.
I don't know if this has always been a problem as I normally use the camera outside and half depress the shutter to take the pic. It was only whilst setting up the still life that I was aware of the problem as I was changing the composition and checking the exposure and composition on the camera.

I changed the meter operating time and this seems to correspond to the time it takes for the changable value to disappear.so perhaps this is design feature that I was not aware of, however I would have thought that display would have continued for the length of the Auto Power off setting.

Perhaps this is not a problem as I suppose that if the metering was limited to 10 sec, I would have to half depress the shutter in order that the meter would re-measure the scene, prior to taking the picture.
However it seems that the Auto Power off does not have any effect as if I set it to 1 min, half depressing the shutter brings it back to life in the same way as if it was set to 30 min (although the screen blanks out after about a minute in both cases)

Could somebody please try this on their camera and tell me if I have a faulty camera or whether the length of the Auto Power off setting is meaningless.

I hope that this is not a hardware fault as I have heard of 5 week delays.

Thanks in advance

I do not think there are something wrong with your K30, because mine does exactly same as yours. In TAv Mode, the camera does not shut down, it only goes into sleep mode and with a half press on the shutter button will wake it up. If it shut down, it would not come back with that half press. Just enjoy shooting my friend.

I noticed all this strange sleep/shutdown K-30 behaviour ages ago and gave up trying to work out the logic of it. It's a bit like there's a menu option missing or something. Just ignore it.

I timed my K-30. I get between 20 and 30 sec. in each setting before it goes to sleep. and off in 3 min. battery 3/4 charged. My DL is a little faster to go to sleep. I just never timed it before. I don't mid sleep as much as off

Thanks for your help.
I was begining to see some form of perverted logic whilst doing my experiments for my second post.
I suppose that the camera has different levels of sleep to save battery life, which are not apparent to the user.
Its rather cold and wet in the UK at present and I hit upon the idea of still life as a way to play with my new toy, indoors. There is a lot of to-ing and fro-ing with this type of photography, moving between the camera, the subject and the lighting and the camera switching off was really annoying. I suppose that I could set it to movie mode and take a movie (which would be discarded) to keep everything switched on prior to taking the final photo.
I am using the 18-55 WR kit lens at F14 with ISO 100 and I was realy impressed with the results. The picture, straignt out of the camera was sharp and I viewed it at 400% in Photoshop and it still looked presentable.
I have a few questions about the Pentax software, but I will create another post.
Thanks again.

There are 2 different timeouts, one for shutdown the camera, and one for meter operating,
the second one can be 3, 10 or 30 seconds, default one is 10s, this setting is explained on
page 95 of the pdf english manual
