P51 using the battery when shut down?

#1 Post by Greg Gebhardt » Sat Jan 06, 2018 3:56 pm

I did not use my P51 for 2 months and when pulled from the desk and plugged in, it’s battery was dead. Puzzled I charged it up to 100% and put in back in the desk last week. This week, one week later, I pull out the laptop and it is down to 80%! Where did the 20% go while it was shut down. The laptop has not been doing this from when I purchased, it seems like it started later like a few months ago. I have pulled it out and started it with 98% power remaining after two to three weeks in the past so something has changed.

What setting could have changed in an update that would cause this. I was thinking maybe the USB is still powered up when my laptop is off, do not know what else it could be and am hoping for experts, here, helping me out.

Happy New Year people, thanks if you can help.

Try disabling network devices (wired or wireless) one at a time and see if the problem continues.

Also run powercfg -devicequery wake_armed from command prompt and see which devices are allowed to wake the system.

OK, figured out what was going on and posting here Incase anyone else has this problem.

My laptop was losing like 20% power each week when shut off. It turned out to the the “USB always on” feature. Some how in the updates from Lenovo this got toggled to,the on position. Was not there when I bought it as it never lost more than a few percent in a couple weeks. I knew something had changed and was going though all my settings and there is was, the USB always on was on which ment even when my laptop was shut down the one USB port was powered up.

Hope it help someone else. I never turned this on so it was an update that caused this.

My P51 has been awesome!!!
