[DNA 75 will not go to 'sleep' - Any ideas?]

well i found what is the use of those two cables.Its for the usb port light.I tried to solder each wire separately,the red one did nothing,the white one gave me only a green light when connected to pc although the battery was not full charged.I then resoldered the two cables back on the originall place and the red and green lights came backas before but again no deep sleep,so i desolder them back.So i guess it is a fault in the desighn on the daughter board,lights on,no deep sleep.Lights off then you have deep sleep.That is the case

Yes the usb port is working properly but with no light

Hi all,

since a few weeks I own a DNA 75 Vapedroid C1D2 showing above mentioned problems. To my surprise this device discharged a half charged 18650 over night down to (measured) 1.8V! Mailed this severe battery killing problem to Ayman Azmy - he responded friendly, but the force was not with him ;-) - he had only an sbody warranty email address for me...

As all problems are not DNA like, I decided to open this nice device
1) remove the battery
2) you see four screws: unscrew and put the battery holder carefully aside, as far as the wires allow  
3) now you can see the DNA 75 board, mounted by 3 screws
4) unscrew and carefully take the electronic board out of the device, as far as the wires allow
5) there is a second board mounted below the DNA 75, mine has printed "D-31" on it. This board carries the microswitches and some electronic components.
6) DNA 75 and D-31 are connected with blank wires - and at one corner point with a red and a white wire
7) grab your soldering iron and remove these 2 colored wires completely
8) put electronic boards and screws back in place

I won a perfectly nice working C1D2 Vapedroid with a DNA 75 inside. All problems mentioned in this thread are gone. 

Warning: doing so you loose warranty and may damage the device. Please follow my procedure only, if you are technically educated - and keep in mind that you may destroy your device by a single mistake.

hi,i had the same problem with my C1D2 not going to deep sleep  so i opened and remove the white and red wire,indeed it now goes in to deep sleep and i have no battery drain,only con is that now when i connect it to pc or charger i have no red or green light through usb port. Maybe those wires are for the charging light from the dna board to the daughter board and for some reason they do a short,anyway i prefer the deep sleep than the light.Next time i open the mod i will try to solder back one wire at the time to see the board behaviour
