G751JY Shutdown Issue (Circuit Problem) Where should i look?

[jdfrench3]

When I post questions to this forum, for user support, answers are expected, please answer my questions.

1. Do you have the capability to "load test the battery"? Here in US we have places where the battery can be tested using a load tester, to check for bad cells. Over the years about 30% of new batteries I have purchased over the Internet are bad upon receipt and I have to get another.

2. How is your charging brick? Does the voltage match that listed on the back of the brick? Again the charging brick can be tested at the local shop (voltage and current).

3. If the charging brick is attached you DO NOT have these problems?

4. What does this following sentence mean? "The original had the same issue. (~70-80%)"
