I got a T100HA tablet without a charger. I want to identify the power adapter for this unit and found that it requires a 9V input.
When the tablet is running, the 9V input will not charge it. Only when the tablet is turned off, the 9V input will charge it.

I could use a 5V charger to charge this unit at any time. However, if I use 5V during usage, the input power is insufficient for the power consumption.
After 1-2 hours, I must turn off the tablet to charge it.

I love this tablet as it meets my needs. Does anyone know how to fix this issue and allow me to...
