  2. Dell Inspiron 1525 - Wikipedia

    en.wikipedia.org/wiki/Dell_Inspiron_1525

    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 ...

  3. Nonvolatile BIOS memory - Wikipedia

    en.wikipedia.org/wiki/Nonvolatile_BIOS_memory

    It is referred to as non-volatile memory or NVRAM because, after the system loses power, it does retain state by virtue of the CMOS battery. When the battery fails, BIOS settings are reset to their defaults. The battery can also be used to power a real time clock (RTC) and the RTC, NVRAM and battery may be integrated into a single component.

  4. Backup battery - Wikipedia

    This is often called the CMOS battery or BIOS battery. The original IBM AT through to the PS/2 range, used a relatively large primary lithium battery, compared to later models, to retain the clock and configuration memory. [2] These early machines required the backup battery to be replaced periodically due to the relatively large power consumption.

  7. Smart Battery System - Wikipedia

    en.wikipedia.org/wiki/Smart_Battery_System

    Smart Battery System (SBS) is a specification for managing a smart battery, usually for a portable computer. It allows operating systems to perform power management operations via a smart battery charger based on remaining estimated run times by determining accurate state of charge readings. Through this communication, the system also controls ...
