markjames Posted February 23, 2008 Share #1 Posted February 23, 2008 Advertisement (gone after registration) I am trying to troubleshoot a problem with the latest firmware update by totally discharging the internal battery and re-installing. Problem is the internal battery won't completely discharge and reset the camera. I have read on the forum where it may take 3-4 days. I'm of course removing the main battery and leaving the camera on "s" with the preference for auto-shut off left off. I've tried 4 days and just recently 5 days. When I power it up again and check the menu, all of my old setting and the date are in there leading me to believe there has not been a total internal battery drain. Has anyone had this experience? Does it take more than 5 days? Maybe I've overlooked something... Mark Link to post Share on other sites More sharing options...

Shootist Posted February 23, 2008 Share #2 Posted February 23, 2008 I have had the same experience. In my case I left the camera on with no battery for 5 days and all setting where the same when I installed a battery. I guess it take longer then that but how long I don't know. Leica states 24-48 hours but that seems to be bull. Link to post Share on other sites More sharing options...
thompsonkirk Posted February 24, 2008 Share #3 Posted February 24, 2008 Same experience as Shootist: 5 days wasn't enough. Link to post Share on other sites More sharing options...
pleeson Posted February 24, 2008 Share #4 Posted February 24, 2008 The owners' manual says there's an internal battery that holds settings for 3 months even if the main battery is removed. Turned off, I'm sure. Link to post Share on other sites More sharing options...
ErikFive Posted February 24, 2008 Share #5 Posted February 24, 2008 Maybe put some pressure on the shutter as well? Like a regular M. Just a thought, but I have no idea if it will work or not. Link to post Share on other sites More sharing options...
marknorton Posted February 24, 2008 Share #6 Posted February 24, 2008 There's a tiny button cell on the DSP board which I expect is used to run the Real Time Clock but user settings are most likely retained in flash memory or EEPROM which are specifically designed not to forget their contents if the battery is allowed to drain. Generally, this information will be written to memory with a checksum and if the checksum is bad on reading the data, the micro will re-initialise it. New firmware levels may add to or change the format of the data but if I was writing the code, I'd migrate the settings from the old format to the new. I've never needed to do any of this battery drain stuff with any of my 3 M8s so it's tough for me to more specific. Link to post Share on other sites More sharing options...
markjames Posted February 25, 2008 Author Share #7 Posted February 25, 2008 Advertisement (gone after registration) Mark, thanks for chiming in - I was hoping you might add something to this thread. I think I'm going to have to call Leica this morning and see if they can't work with me on the phone. On one of my M8's I didn't quite wait the 3-seconds on the firmware update and since then I've had a wacky, non functioning scroll wheel and intermittently, the WATE menu appears sometimes with non coded lenses and won't go away until I remove and reinstall the battery. I was hoping to discharge the internal batter first before reloading the latest firmware but it doesn't seem like that's going to happen any time soon. I've tried reloading firmware after waiting 4-5 days with the main battery out, following all instructions exactly, but I still have the new scroll wheel issue and WATE menu randomness. I need to find out from Leica what the result is when NOT waiting the 3-seconds before clicking 'yes' on the firmware upgrade. I'd hate to ship my second body all the way to Solms for something that can be reset in five minutes. Mark Link to post Share on other sites More sharing options...
marknorton Posted February 25, 2008 Share #8 Posted February 25, 2008 Mark, I had the same problem with the WATE menu appearing and I found all I needed to do was use the RESET function in the main menu. So I would try the following: - Reset the camera from the menu - Reload the firmware - Reset the camera again I'm not sure what the 3 second thing is to do with, if it genuinely required, for example, to wait for the SD Card to go ready, it's sloppy programming.

markjames Posted February 25, 2008 Author Share #9 Posted February 25, 2008 Mark, Tried your 3-part suggestion (with high hopes) and still have the same issues. Scroll wheel just jumps between two adjacent bars, and the WATE menu keeps coming up when I mount my 21mm Zeiss which is uncoded. I don't have these problems with my other, 6 mos. older, m8. Any other thoughts? Camera still operates but I can't get past the WATE menu when I mount the lens and the UV/IR with lens detection is on. In fact, the menu comes up even after I turn the camera off and restart it. ?? Mark Link to post Share on other sites More sharing options...
SJP Posted February 25, 2008 Share #10 Posted February 25, 2008 and the WATE menu keeps coming up when I mount my 21mm Zeiss which is uncoded. If it is only that lens then did you try sticking a white paper label on the lens bayonet mount (opposite the IR sensor). Maybe it is detecting a screw as 'coding'?

Sounds like there is some hardware failure to do with lens detection, but without detailed schematics and the camera diagnostics, it's tough to know what is going on. I think your camera needs a holiday in Solms. Sorry! Link to post Share on other sites More sharing options...

Try wiping that down even a little lens cleaner there will not hurt the mount. Check you lens mount also for dirt . May not help but worth a try.

markjames Posted February 26, 2008 Author Share #13 Posted February 26, 2008 Guy, I did look at the sensor window and it appears clean. I wound up calling Dave at Leica Repair in New Jersey this afternoon and he was stumped as well and said I should pack 'er up and send her in. Although I take some pride in being able to troubleshoot most problems I gave up on this one after five weeks. I thought I had escaped any meetings with the Leica service group but my number two body is now on a plane somewhere en route. Good news is, so I'm told, they will probably fix it in NJ and not have to send it off to Solms. I was told that Leica NJ is pretty much up to speed with their repair facilities and at worst I'm looking at a month's wait time until I get it back.Fingers Crossed.

The Zeiss 21 has a screw in an akward place. Try filling that screw with white paint. Link to post Share on other sites More sharing options...

Mark Well always hate to send stuff in but sounds like a holiday maybe in order. BTW leica NJ has made some improvements from my conversation at PMA with Leica. Hopefully you will see that.
