Possible dead or shorted battery in tablet?

[Da Mail Man]

I Have an issue with a trio stealth - 10 mst10-21, 16gb memory tablet...Android OS.


Years back, I received this and decided to try my hand at replacing the cracked screen (digitizer) which
came out perfectly and applied a screen saver also.......

I had forgotten all about it and dug it out with factory power supply...I turned it on, booted right up...

Accessed my wifi with no problems...I saw that the batter was VERY low so, plugged in the power supply
and watched the screen "fad to black"...That's all she wrote...

Turning it on with the power supply plugged in - nothing happens...Same with "charging it" for 2 days, same results...
>

Took voltage measurement from power supply, checks good...
Is this battery past the point of no return>?...Suggestions?

From what I can see, that device was released around early 2010s, so for a 16 year old device that hasn't had a battery replacement (that we know of), then it's most likely the battery, though I would have thought the device would turn on if it had a charger connected.

Nope, no known battery replacement...Some batteries drain as we all know but, sometimes I believe they short out...

If the charger were connected, that charge would go "across" the battery and, if battery was shorted, no charging or running off of the power supply probably would not occur....Had this happen to me a very long time ago but, don't remember what it was on.......

Thanks for the reply.....
