CF 19 battery drain

CF 19 mk4..
ublox gps
dual touch conversion
intel 6300 wifi
SSD
fingerprint reader
4gb ram
custom backlit keyboard.
Win7..32bit


Battery has slow discharge if I leave it in the CF19. Not a full drain overnight. Probably take 3 or 4 days to drain completely..maybe longer..tried 2 different batteries. Same results..Batteries ok if left out of CF19
