Laptop sudden shut down on battery power only, even though plenty of battery life left. Event viewer schannel 36887.

It is not surprising that none of those ideas produced a result.

The reason the reply that doesn't produce a result is marked as the "Answer" is because the reply that doesn't produce a result was posted by a Microsoft engaged Support engineer "expert" and then the topic went idle for 5-10 days and when that happens another Microsoft engaged Support Engineer "expert" marks the reply that doesn't produce a result as the answer even if it is impossible to be the answer. 

In this case it only took 7 days for the automatic answer marking nepotism to kick in:

That is how they choose run things in the MS Answers community.  It is extremely, extremely unlikely that any reply from a Microsoft engaged "expert" marked as the "Answer" by another Microsoft engaged "expert" is really going to be the answer. 

The sad truth is that the since the forum owners allow this nepotistic answer marking practice of one alleged "expert" looking out for another alleged "expert" to continue unabated, the MS Answers community is polluted with thousands and thousands and thousands of "Answers" that are not really answers at all. 

It is also extremely unlikely that the Microsoft engaged Support Engineer "expert" is following this topic at all so I would not hold your breath waiting for a reply.

The best thing to do is start a new topic/thread/question about your particular issue so it will appear at the "top" of the list of new and unanswered questions.  That will get you the most visibility and best eyeballs on the topic.

Unfortunately, you are right, and extremely bold to face and report the truth as it is.

I just would like to add my counterattack to this type of 'automatic' prize to poor answers, since it happens also to my threads, and i get very disappointed when, simply by forgetting the thread and letting the dust cover it, the answer given by a noticeable user has been marked as THE answer; in this case, the author of the thread, who should remember his open threads, must uncheck such answer through the specific button under the post, such that all the other users get aware of the fact that the problem under consideration is not solved yet.

None of these methods has been able to produce a result. Which is the next path to follow?

Hello,

Thank you for visiting Microsoft Community and providing us with the detailed description about the issue.

As per the description, I understand that you are experiencing issue with frequent shut down of the system.

I certainly understand your concern and will try my best to help you.

In order to understand the issue more clearly, please provide me with the following information to provide you with the targeted assistance.

1. Did you make any significant hardware or software changes recently in the system?
2. Since how long are you experiencing this issue?
3. Are you getting any error message? If yes, what is the exact error message along with the error code?

I really appreciate all your efforts in trying to fix this issue.

This issue might have occurred if any third party application is causing conflict or the drivers are not installed properly or they are corrupt. It could also be due to incorrect power settings.

I would suggest you to try the following methods and check if that helps.

Method 1:

I would suggest you to try the power troubleshooter and check if that helps. Please follow the steps in the link given below and check if that helps.

Open the Power troubleshooter

http://windows.microsoft.com/en-US/windows7/Open-the-Power-troubleshooter

Note: The Power troubleshooter checks things like your computer's timeout settings, which determine how long the computer waits before turning off the monitor display or entering sleep mode. Adjusting these settings can help you conserve power and extend your computer's battery life.

If the issue persists, follow method 2

Method 2:

To diagnose the problem whether any third party program or application is causing the conflict, I would suggest you to try “clean boot” and check if it helps.

Important: Placing your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot.

**How to perform a “clean boot” in Windows,**please follow the steps in the link provided below.

Note: Refer "How to reset the computer to start normally after clean boot troubleshooting" to reset the computer to start as normal after troubleshooting.

Try to reboot the system and check if it helps.

If the issue persists, follow method 3

Method 3:

Please refer to the article given below and check if that helps.

Change, create, or delete a power plan (scheme)

Note: A power plan is a collection of hardware and system settings that manages how your computer uses and conserves power. Power plans can save energy, maximize system performance or balance energy conservation with performance.

I hope this information is helpful.

Please do let us know if you need any further assistance, we will be glad to assist you.

Thank you.
