Phone turned off?

Question

HTC

Since yesterday evening, I have been using HTC HD2 as an access point to the Internet.
Just yesterday, he began to behave strangely, hung up a couple of times, but after removing the battery, he turned on normally.
Today, after working as a point, it turned off and everything does not react to anything.
Has anyone had a similar experience with a phone?

Answer 1

Answer 2

Check the battery, for example, on the Desire HD, it also passed out and did not want to turn on even with charging. We put an acc from another phone and everything turned on. It turned out the battery had died.

Answer 3

hard reset.
