  2. Nonvolatile BIOS memory - Wikipedia

    en.wikipedia.org/wiki/Nonvolatile_BIOS_memory

    Higher temperatures and longer power-off time will shorten battery cell life. When replacing the battery cell, the system time and CMOS BIOS settings may revert to default values. Unwanted BIOS reset may be avoided by replacing the battery cell with the PSU power switch turned on and plugged into an electric wall socket.

    For both the 1525 and 1526, a low CMOS battery can prevent the computer from operating properly. [18] [19] Replacement when done the "right" way requires removal of the main board, as the CMOS is located on its underside. However, there is a method that involves shimming the case open and using an angled pick to remove and replace the battery ...

    CMOS inverter (a NOT logic gate). Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss ", / s iː m ɑː s /, /-ɒ s /) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions.

    The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...

  8. Active State Power Management - Wikipedia

    en.wikipedia.org/wiki/Active_State_Power_Management

    This is usually managed by the operating system's power management software or through the BIOS, thus different settings can be configured for laptop battery mode versus running from the battery charger. Low power mode is often achieved by reducing or even stopping the serial bus clock as well as possibly powering down the PHY device itself.

  9. Embedded controller - Wikipedia

    en.wikipedia.org/wiki/Embedded_controller

    Many BIOS updates also include upgrades for the embedded controller firmware. An embedded controller is sometimes known as a "Keyboard Controller BIOS", which comes from the fact that the embedded controller evolved from the keyboard controller and often still is used as a keyboard controller.
