Won’t turn on

[Thomasb]

I hope you can help I have a linx 10 tablet and I charged it the other day and the battery run low so I have gone to charge it again today and the blue light is showing but the tablet won’t turn in so I left it to charge for an hour thinking the battery may be fully dead and needs a good charge and I’ve come back and it’s still not turning on so I unplugged the power source and the blue light is stuck on but the tablet won’t turn on? Any suggestions on how to fix it
