MacBook Users Reporting Trouble with External Keyboards/Mice

According to a recent post on MacFixIt.com, some users have reported troubles using external keyboards and mice with their MacBooks after waking the laptops up from safe sleep. The issue is sometimes accompanied by reports of underpowered USB ports.
Some users have reported successful fixes in disabling the option “Allow Bluetooth Devices to Wake this computer” in Mac OS X’s Bluetooth pane of the System Preferences menu.
Others have found a more technical fix to disable Safe Sleep in general by entering the following command in the Terminal program:
sudo pmset -a hibernatemode 0
Stay tuned for more on the story as it develops and if you have and ideas, fixes or workarounds, be sure to post them as comments.

To reduce the weight of batteries, lithium is the way to go, which is also substantiated by the prominence of rechargeable Li-ion batteries in e.g. mobile phones, cameras and MP3 and MP4 players.
