Battery Draining and Laptop Heat on Maverick
2 months old mid 2013 MBA 128GB Flash, 4GB RAM, i5. Before maverick update, the laptop lasts for 13 hours as advertised and only drains ~3% of battery overnight.
After the maverick update, the battery drains from 100% to 2% overnight in sleep mode with all programs closed and I can feel the heat near the air vent constantly.
Adding on, with low power CPU usage, my laptop gets incredibly hot, especially at the top right corner of the computer.
This is the info from etrecheck in Safe mode.

Report from Rember
Test Results
All tests passed!
Total built-in memory: 4 GB
This is the total amount of physical memory that the computer has installed. If this figure is not showing the correct amount of memory there may be a problem with one or more installed DIMMS.
Available memory: 202 MB
Available memory is the amount of physical memory that is currently not in use by any other processes. All available memory will be used for testing when the "All" option is selected. To increase the amount of available memory, you can restart your computer before testing. If you are familiar with the command line (CLI), you can run memtest (the core of Rember) in single-user mode. See Rember help, or http://www.memtestosx.org for more information.
Requested amount: All MB
The total amount of memory requested for testing by the Rember application. Not all requested memory can be allocated for testing. See information on "Available memory" for more information.
Memory allocated for testing: 197 MB
This is the total amount of memory that memtest was able to allocate for testing. See "Available memory" section for more information.
-------
Loops selected: 1
Total loops selected by user for testing. All loops should complete when testing is successful. Test failure when the "Continue on Error" preference is selected will cancel tests before this number of loops has been completed. Users can also cancel testing before this number is reached.
Loops completed: 1
Total loops completed by memtest. Note that the Rember is not always able to identify how many loops ran. If there are discrepancies between this and the loops selected, the log should be examined to determine exactly how many loops were performed.
-------
Total execution time: 62 seconds
This is the total amount of time that it took to execute the selected tests. Execution time may vary from system to system, and is provided as a guide for determining how long users can expect tests to run based on the amount of memory installed on the system.
Testing start time: 2013-11-15 14:03:23 +0000
Testing end time: 2013-11-15 14:04:25 +0000
Hope you can get something from this, Lex. Thank you for your help!
