Hi, Something wakes my MacBook Pro i searched this forıum and others could not find anything close to this problem, when i close lid it goes to sleep but in the morning when i open lid i see battery is drained when i checked the logs i saw these; Sleep (Failure code:0x1F006500): Using AC (Charge:100%) and LID is closed Clamshell Sleep: Using BATT (Charge:78%) Wake [CDNVA] due to EC LID0/HID Activity: Using BATT (Charge:73%) LID is open Clamshell Sleep: Using BATT (Charge:57%) and Jan 15 22:51:23 *-mbp kernel <Debug>: Wake reason: ?

OHC: stands for Open Host Controller, is usually USB or Firewire. If you see OHC1 or OHC2 it is almost certainly an external USB keyboard or mouse that has woken up the machine. EHC: standing for Enhanced Host Controller, is another USB interface, but can also be wireless devices and bluetooth since they are also on the USB bus of a Mac. USB: a USB device woke the machine up LID0: this is literally the lid of your MacBook or MacBook Pro, when you open the lid the machine wakes up from sleep. PWRB: PWRB stands for Power Button, which is the physical power button on your Mac RTC: Real Time Clock Alarm, is generally from wake-on-demand services like when you schedule sleep and wake on a Mac via the Energy Saver control panel. It can also be from launched setting, user applications, backups, and other scheduled events. During sleep i didnt open LID and no USB is plugged and this happens after Mavericks is installed, i didnt have this problem before (Snow Leopar - Lion). Please help me to solve this problem.
