1) The definition of the screen is superb for size: 10.1 "1366x768 !!! Perfectly readable. 2) The battery pack is 6600 mAh (usually between 4400 and 5200 or 5600) 3) The sleep mode is "slow" but allows almost immediate and secure recovery (hard disk hibernation + classic standby RAM that allows a recovery in less than 10 seconds. If the battery is removed while the Hibernation windows 7 be used). Enough reagent for a Netbook.
