答案揭曉了 之前休眠換不醒
要軟開機才能用 果然是8.1的問題
難怪維修無用....
簡單的說就是CPU和電源出現了軟體邏輯的衝突...?
預計在下次韌體更新時修復
I’m sorry we’ve been dark – I work closely with the Lumia engineering
team that’s working directly on this. Trying to shed a little light on this…
Beginning in early September we started to receive an increased number of
customer feedback regarding Microsoft Lumia 1020 and 925 device freezes.
During the last two months we have been reaching out for more and more data
and devices to systematically reproduce and narrow down the root cause. It
turned out to be a power regulator logic failure where in combination with
multiple reasons the device fails to power up the CPU and peripherals after
idling into a deep sleep state.
I am pleased to pass on that we have a fix candidate under validation
which we expect to push out the soon with the next SW update!
Appreciate your patience.
