There is a spring like machinal switch under it that sometimes becomes clogged with dirt or lint. If this isn’t the issue you can try flashing the BIOS as sometimes this is the issue. However if the battery is that old and degraded it may not be able to pull enough power to start the boot cycle. This tends to happen below 25% power especially if one of the cells(likely 18650’s) has become a drainer. Does the battery hold power over a couple of days without it in use and removed? A laptop or PC draws the most current at one time right as you push the power button. This may also explain why when you plug it in it works.

Can you turn on without a battery installed?
