will not boot, despite charging all night
Hipstreet Vanguard 2 Tablet, using Android Lollipop refuses to boot up.
Have tried the opened paperclip method, to get a factory boot, but nothin, does not even light up.
This unit has been to Ontario, Canada, _twice_ to the repair centre. Two or three days operation, after each 10 to 20 day absence, does not make for a useful device, imho.
Edited, by adding remarks:
Used 2 different, known-good power supplies, with no response.
Tested the Vanguard 2's power supply on my Samsung Galaxy Tab 3, and the Galaxy happily charged on it!
Tested the Vanguard 2 on my acer Aspire Win 10 Laptop, which did not 'see' it.
The Aspire Win 10 Laptop 'sees' my Samsung Galaxy Tab 3 just fine.
I plan on opening up the Vanguard 2's case, this weekend, to see if the Power Switch is faulty. (I am a retired Seismic Surveyor, who opened up a Wang 600 to swap out a faulty built-in printer, as my first venture into non-survey-instrument surgery!). I have a couple different bench-top multi-clamp devices, plus a 6" diameter magnifying-glass c/w built-in lamp.
Это хороший вопрос?
