If we’re talking about a laptop, then leaving it alone for a couple of years would do little damage: your battery will be dead, but you can quickly charge it. Unfortunately, it doesn’t work the same for a musical instrument such as a piano.

In August 2019, I found an old piano that seemed to be forgotten about. A bit of context here, my primary role at work is as a Principal Software Engineer (Keyword Software). I like to explore other topics in-depth with my hobbies. This piano restoration project is one of them.
