Why Is My Laptop Battery Not Taking Charge After 79%?
Most laptop manufacturers know how important battery is for users so they allow you to be in total control when it comes to its settings. HP, for example, is home to HP Battery Health Manager which lets users select “Let HP Manage My Battery,” “Maximize My Battery Health” or “Maximize My Battery Duration” based on usage and the age of their device.
1. Let HP Manage My Battery Charging:
This setting simply changes how the system charges the battery based upon usage conditions and temperature over time. It is a sensible choice for users who regularly remove their notebook from AC power and expose the battery to discharge. This is the ideal setting for notebooks that were bought less than few years ago.
2. Maximize My Battery Health:
This setting restricts the maximum state-of-charge on the notebook battery to 80%, which is very useful for optimizing battery health and preventing battery swelling due to high state-of-charge. It is a reasonable choice on notebooks that are few years old.
3. Maximize My Battery Duration:
Use this setting if you need your battery to last as long as possible between charges. Your battery will charge to 100 percent to stay running longer between charges. It is the appropriate setting for those who are tired of the battery stuck at 79 percent problem.
