I bought the above device online, but even after changing adaptors and power sockets, ai can’t get the device to power up. The power suppluly is getting the power (got checked) and the device makes a brief sound, but nothing after that. Even bluetooth or power indicators do not come on. What could be wrong?
There IS a problem with 20v to 5volt conversion. A circuit called 54335 to changé or solder a miniconverter card instead. Tutorials on youtube
