I have an old (app. 4 years) Pavilion Notebook. The keyboard has started to bulge upward on the left side. Would this be due to a failing battery or possibly some other reason? Thanks for any advice.

Likely the battery - it is a component in the computer that can indeed "swell".
From what I have read, the situation is not dangerous (won't catch on fire or explode, for example).
The issue must be attended to prevent further (additional) damage to the rest of the computer.

Battery having trouble?
- If the “not charging” issue is (only) apparent when the system is running hot (or near that point), the battery and charge system are likely overheated as well – the charge system will resume operation when the computer cools down. Short Version: An overheated battery / computer / charging-system will not charge the battery – this is normal behavior.
- The battery might be OK and just need calibration (balance / set).
The steps to check / calibrate / replace the battery are included in this document:

Document includes information and link for testing the hardware using HP PC Hardware Diagnostics (UEFI) (preferred method) and / or using the HP Support Assistant to test the battery.
