Chuwi Air Pad - logo appears but the tablet does not switch on

I purchased CHUWI HiPad Air 10.3inch | Android 11 | LPDDR4 6GB |128G eMMC - this tablet is troublesome from the beginning - it used to work very slow and when I try to open it - I see the logo and the tablet switches off - I purchased this in July last year

Faulty Battery may be… instead of using the supplied adapter, plug in with Type C charger, if you have one for another laptop. That should take you further. Then check if the battery is recognised.

hi, the same problem. screen logo but can’t boot. if you plug (also other charger tested) no battery loading appears, just the chuwi start screen. pls help
