jenxi Posted June 4, 2012 Share #1 Posted June 4, 2012 Advertisement (gone after registration) Hi, I just got my first Leica, a used M8. However, after I got home, I realised that the date and time refused to be set. I have changed them accordingly and saved them. The EXIF and menu page only show 01/01/1970 and 00:00. When I choose settings and go to the menu pages where I am supposed to set the date and time, the previously set times are there. How can I deal with this issue? Is it a dying or dead internal battery that won't save the information? If so, how can I rectify it? Would I need to send it in for the battery to be replaced and what's the estimated cost of doing so? Link to post Share on other sites More sharing options...

jaapv Posted June 4, 2012 Share #2 Posted June 4, 2012 First reset the camera by running down the battery as far as it will go ( Autoshutoff off). If that does not do the trick, try reloading the firmware. If it still has amnesia problems it is indeed a case for the friendly gnomes in Solms, or your local repair facility.

jenxi Posted June 4, 2012 Author Share #3 Posted June 4, 2012 Thanks jaapv! The used dealer suggested that I update the firmware. It was 2.000 and I updated it to 2.014. The problem didn't go away. I'll try running the battery down to see if it helps. Would it be a costly repair? The shop gave a three-month warranty but I'll have to check with them if covers such a repair.

jaapv Posted June 4, 2012 Share #4 Posted June 4, 2012 It should cover this, otherwise what is a guaranty for? Otherwise just return the camera. It is not as if second-hand M8s are a rarity. However it is quite possibe that the camera has been sitting unused without a battery for more than three months. In that case the internal battery will just have run down, it would take up to 48 hours to recharge. Link to post Share on other sites More sharing options...
jenxi Posted June 4, 2012 Author Share #5 Posted June 4, 2012 I'll keep my fingers crossed and hope it just needs to recharge. Thanks once again Jaapv. Link to post Share on other sites More sharing options...
Guest Ming Rider Posted June 7, 2012 Share #6 Posted June 7, 2012 There seems to be a sudden rise in the number of peculiar firmware anomalies lately ? Link to post Share on other sites More sharing options...
jdlaing Posted June 7, 2012 Share #7 Posted June 7, 2012 Advertisement (gone after registration) There seems to be a sudden rise in the number of peculiar firmware anomalies lately ? I think proportionate to the additional numbers of bodies sold? Link to post Share on other sites More sharing options...

jank Posted June 8, 2012 Share #9 Posted June 8, 2012 Hey guys, the problem has been resolved. It took the camera some time time to recharge the internal battery. In general, the clock (Real Time Clock =RTC) is usually designed in as a separate IC drawing less than 1 uA which for it to work requires a battery for continuous operation, usually a small Li battery (3V).The cost of components in medium quantities ( 1000s) is less than $2. The battery could also be replaced by a large capacitor holding the charge for several days to possibly weeks. In battery case , using diodes (15c) the circuit is designed such that when the main battery is in, and charged, it supplies all the needed power to the the RTC so the backup battery has extended life. In capacitor case the main battery keeps holding the capacitor at full charge. When the main battery is removed, the cap. slowly discharges and after few days or weeks it can no longer supply enough power to the RTC to continue running. I assume Leica took capacitor approach, Since the capacitor does not ever ( hopefully) need replacement, no repairs are needed.In worst case one has to put in the main battery and let it charge the capacitor, then reset the clock rather than sent the camera to Solms to replace 35c battery.

Could you please explain that how to recharge the internal battery? how many days did you take for recharging the internal battery? Waiting for your comments.

jaapv Posted March 2, 2021 Share #12 Posted March 2, 2021 If the internal battery does not recharge within 24 hours, or keeps draining, it must be replaced by Leica. Link to post Share on other sites More sharing options...
