I've had my laptop for almost three years and I'm not sure if this is normal for the age for my Laptop's battery

Welcome to the HP Community Forum.

It is normal for the battery to degrade over time and after many cycles of charge - use - charge - use.

Batteries are meant to be replaced when they can no longer maintain a charge.

Consumer grade computers typically come with batteries that last as long as a standard warranty (one year) or a bit longer.

Information / Tests

This section does not apply to a bloated, inflated, swollen battery.

If you know the battery is failing / has failed - skip this section.

Consider checking whether the BIOS can be updated on your computer. 

Out-dated BIOS might result in odd issues, including the battery not charging during Hibernation.
