-### FlexiCharger
+### Charging Thresholds
 
-On several models of our laptops, FlexiCharger can be used to change the charging behavior of the battery.  A general consensus is that charging a battery to 100% every time will shorten its overall lifespan.
+Configuring charging thresholds will allow your System76 laptop to disable the
+charger and run off the AC connection when the battery reaches a specified
+capacity. This is particularly useful when your laptop is plugged into AC power
+adapter for extended periods of time as it prevents unnecessary micro-charging
+which reduces battery longevity.
 
-To adjust the top charge, reboot the computer and enter into BIOS by holding down <kbd>F2</kbd>, and navigate to Advanced, then Advanced Chipset Control, and set Flexicharger to Enabled. Two new sub-menus will appear, and can be set to the user's desired percentages. The longevity of lithium batteries is dependent on the number of charge cycles they go through. The larger the percentage of spread between Top and Bottom charge percentages, the longer the physical battery will last. For optimal longevity, charge cycles of 40%~80% are a good idea:

+
+#### Open Firmware
+
+On laptops with System76 Open Firmware, charging thresholds are exposed through
+ACPI. The `system76_acpi` kernel module then makes these available through
+standard sysfs entries.
+
+- `/sys/class/power_supply/BAT0/charge_control_start_threshold`
+- `/sys/class/power_supply/BAT0/charge_control_end_threshold`
+
+The default values of 0 for the start threshold and 100 for the end threshold
+disable the feature.
+
+#### FlexiCharger
 
-- FlexiCharger will allow your System76 laptop to run solely off the AC power connection, and leave the battery alone while the computer is operating normally
-- This prevents unnecessary micro-charging which reduces battery longevity
--  It is particularly useful when your laptop is plugged into AC power adapter for extended periods of time
-- FlexiCharger can be disabled at any time in the BIOS, which reverts the charging profile to factory defaults. Before heading out into the wild blue yonder, disable FlexiCharger to charge your laptop battery to 100%.
+FlexiCharger is the implementation of charging thresholds in proprietary
+firmware, made available as a BIOS setting.
 
-#### Open Firmware 
+To adjust the top charge, reboot the computer and enter into BIOS by holding
+down <kbd>F2</kbd>, and navigate to Advanced, then Advanced Chipset Control,
+and set Flexicharger to Enabled. Two new sub-menus will appear, and can be set
+to the user's desired percentages. Once configured, save and exit the BIOS.
 
-Laptops that ship with our Open Firmware do not have FlexiCharger.
+FlexiCharger can be disabled at any time in the BIOS, which reverts the
+charging profile to factory defaults.

 When you power on, you'll be prompted to create a user account, which is an administrative account (in the sudo group). The password you set for this account will be the main password for when you install applications or updates, or add new users to the computer. In Pop!_OS, you can choose to encrypt your hard drive while setting up the user account. If Ubuntu was picked during configuration reinstalling the OS will be needed to set up encryption and instructions for that can be found [here](/articles/install-ubuntu).
 
-You will be prompted for the encryption passphrase first if you select that option during the account creation process. After the encryption passphrase is set, you will proceed to set up a user account and be prompted to set the administrator password. If you encrypt your hard drive, you will be prompted for the encryption passphrase every time you power on. It's important to write this password down and keep it somewhere safe. If the password is lost or forgotten, you will lose access to the contents of the drive.

+NOTE: The administrator password and the encryption passphrase are separate. Users can set them to have the same characters, but to the OS they are different items. It is good security practice to make the encryption passphrase and the administrative password different. However, this means that when prompted for the admin password, the encryption passphrase will not work, and vice-versa.
+
+This administrator account has sudo rights, but it is not the root account. Some distributions (like Debian) have you set up a separate root account. Ubuntu and Pop!_OS do not.
