Resolved System Information scan not possible

I have been trying to test some laptop batteries and have used the 'powercfg -energy' command ONCE. Having looked at the results in the html file I made some changes as recommended and restarted my machine.

On trying to use the same command again, I received the following message:

"C:\Users\MyName\Desktop>powercfg -energy
Enabling tracing for 60 seconds...
Observing system behavior...
Could not open the NT Kernel Logger. The NT Kernel Logger is already in use. Ensure that all other performance monitoring utilities, including Reliability and
Performance Monitor are not currently in use.

C:\Users\MyName\Desktop> "

The only program I had running was the command window.

How do I get the 'powercfg' command to work again?

 

Might be a dumb question, but you did shut down before doing the next one. Not just leave the AC plugged in and switch batteries.

 

Thanks to you TonyT and MrBill for your answers and suggestions.

Interestingly I have just run three consecutive sessions without powering down, restarting or logging off. Here is a copy of the command line window. Between each I made some changes, saved them and had a look at the reports. Some of the advice I accepted and some rejected. I hope they were the right choices. I was trying to reproduce my previous experience, but as you can see I was not able to do so.

As a matter of interest, I did not find any very useful information about my battery. I did find out about power settings though. Here is the battery info:

Battery:Battery Information
Battery ID 3580LGC-LGCEV06047
Manufacturer LGC-LGC
Serial Number 3580
Chemistry LION
Long Term 1
Design Capacity 56160
Last Full Charge 50522

I think if I do get the problem repeating in the future I will have an idea what else to try.

Thanks again.

PS I did not change the battery in this test. Could this be a significant factor?

 

Are you testing your HP Pavilion.

 

Thanks for your tips, TonyT and lj50.

I am using my HP Pavilion. I have not long had it back after the GPU was reballed. I had all sorts of dire warnings from a local repair shop about the process, but my laptop is working fine now, I even got my DVD drive working again, the subject of an old post. Seems it was a hardware fault after all as I have the same SSD back in use with the identical software. Arie if you read this, please note! And another benefit, it was a lot cheaper than getting another Win 7 licence.

I have tried to load the battery check from HP but another good one is to be found in Ubuntu 14.04, or perhaps I should not mention it here! I have an HP Pavilion with Ubuntu so I shall do the checks with that one in future.

Thanks again, guys.
