Power-on hours (POH) is the length of time, usually in hours, [1] that electrical power is applied to a device.. A part of the S.M.A.R.T. attributes (originally known as IntelliSafe, before its introduction to the public domain on 12 May 1995, by the computer hardware and software company Compaq), [2]
An ampere-hour or amp-hour (symbol: A⋅h or A h; often simplified as Ah) is a unit of electric charge, having dimensions of electric current multiplied by time, equal to the charge transferred by a steady current of one ampere flowing for one hour, or 3,600 coulombs. [1] [2]

While RAS originated as a hardware-oriented [citation needed] term, systems thinking has extended the concept of reliability-availability-serviceability to systems in general, including software: [4] Reliability can be defined as the probability that a system will produce correct outputs up to some given time t. [5]
High availability software can help engineers create complex system architectures that are designed to minimize the scope of failures and to handle specific failure modes. A “normal” failure is defined as one which can be handled by the software architecture's, while a “catastrophic” failure is defined as one which is not handled.
One solution that can help identify why your computer is running slow is a comprehensive system tune-up, like System Mechanic. The software package helps provide real-time performance boosting by ...

A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [ 1 ] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.
