Would anyone be knowledgeable?

I have an old 8 GB SanDisk Clip Sport that I am trying to resurrect if it can be done easily.

Yesterday I left it connected to my Linux Computer USB for two hours.  The screen read "Low Battery"

This morning, I plugged it into a house charger and left it charging for nearly three hours. The same "Low Battery' Screen appeared.  If I hit the power button the MUSIC screen appears.  I had music on there from tinkering years back.  The unit seems to operate fine (I plugging in earplugs and listened to music) while charging, but as soon as I disconnect the charge wire no matter what the screen view, it all goes dark.

On line searches have not been helpful.

Any thoughts?

...fyi leaving it even longer on the charger just in case
