Abstract: An electronic device supplies power to system load(s) from a first battery power source and a second battery power source connected in series across a re-configurable device section boundary. A battery monitor monitors voltage across each individual battery cell within the first and second battery power sources. The battery monitor directs a charge circuit as to how and when to charge the first and second battery power sources using an external power source. The battery monitor also directs the charge circuit as to how and when to use the first and second battery power sources to power the system load(s).

Abstract: A server hosted by a server computer is protected against anomalous logons. A working time profile is generated from an access log that has a record of logons to the server. Counts of access events per time period (e.g., per hour) are parsed from the access log, and processed using statistical procedures to find candidate working hours. A working time range includes candidate working hours. An account logging on the server is detected. The logon by the account is deemed to be anomalous when the logon is at a time outside the candidate working hours.

Abstract: An asynchronous state machine (ASM) for managing deep sleep state of a device and related methods are described. One method includes the ASM automatically detecting a request to wake up the device based on either a change in a status of a power user-interface element associated with the device or upon a detection of an attachment of an external power source to the device. The method further includes the ASM automatically initiating a wake-up sequence including turning on a battery pack associated with the device. The method further includes the ASM automatically detecting whether a power management function associated with the device is enabled and automatically transferring control of a remaining portion of the wake-up sequence to the power management function and the ASM passing the status of the power user-interface element to the power management function as needed.
