Win10 1903 -- Battery 1 not detected -- Windows glitch?

2019-06-04, 11:59 AM

For some time, I had been having a problem with the internal battery in my X240 not being detected.  I assumed, ultimately, that it was a problem with the battery, which had started to exhibit this behavior after six months or so.  ISTR verifying this in Vantage, and that a reboot would (usually) fix it.  However, recent events have led me to wonder.

 

Two weeks or so ago, I installed a new internal battery, and the problem seemed to go away, which was nice. 

 

Then, a few days ago, I installed the latest version of Windows, version 1903.  Not long after that, I started to get sporadic warnings that told me that battery 1 [internal] was not detected.  The Windows battery gauge showed that only one battery was funcional.  What made this especially odd was that when I checked Vantage, it was installed and healthy (should have done that before).

 

Anyway, I decided to try something and went to Device Manager and deleted both batteries (present there), then did a scan for changes.

 

That fixed the problem.  The windows battery gauge correctly reported the internal battery, all was well.

 

I haven't had a recurrence since I performed this action, but I will keep an eye out.  It's interesting that the Lenovo software properly detected and assessed the batteries, but that Windows didn't.  This makes me suspicious of a possible problem in Win10 1903...

 

Any thoughts?

OK, I'm seeing recurrences of this.  Handling things through Device Manager always fixes the problem--though I don't know which of the power items (Adapter, Battery, Battery) I'm deleting actually does the fix.  I am going to look a little more and see if I can built a batch file to handle the reset. 

 

But I just wonder wether this is likely to be an issue with the battery hardware, a failing in some Lenovo software or firmware, or a bug in Windows.  Anyone else have similar experiences or any insight??

I was having a similar issue and your solution fixed my issue too. After upgrading to an SSD for my X240, I stared having battery issues with Win10. Cripping slow charges times (5 hrs per battery +) and also a battery 1 that kept dissapearing. I removed the 2 batteries from the Device Manager, however this time I also removed the Microsoft AC Adapter. Also worthy of note is that there is a change in the windows battery info box from the status bar. Information on what battery is being charged is no longer displayed - just the % of each battery & if the latop is currently being charged.

 

I will do a Battery Guage Reset later. At the moment Windows and Lenovo seem to disagree on how long charging will take to be 100%. Just as a matter of interest, how many hours use are you getting out of the X240? About 4 hrs tops is the most I see with an internal + the slimline 3 cell.

Yeah, I'm at about four hours with that configuration as well.  Not a big deal as I keep chargers at work and at home.

 

The Battery 1 problem seems to recur after a little while.  I'm thinking about seeing if I can build a .BAT file to delete those items and force a rescan, but I suspect command-line tools to do that sort of thing are rare.

Ok just to give an update. Installed Chrome OS, seems to work great for the girlfriend. However after disconnecting the internal battery  (while it waits for a replacement) as it went back to having "charging issues", now the detachable slim battery is reporting that it is not genuine. In a nutshell, even though when I had Windows 10 on there fully installed, both batteries reported as "good" with serials and with part numbers... have turned out to be as genuine as *%&$$$&*!!@@

 

Its taking a while as the unit is bought 2nd hand here in Vietnam & to keep the 12 month "warranty" I have to tell them whats wrong without taking the cover off. So visits are weekly. So far the keyboard experiance is as good as everyone says. Makes my other machines which are all Mac's seem a bit poor by compairson. Have to say the support and community here is amazing.

AM-S, if you're still here, can you answer another question?  I'm wondering if you're using the Lenovo power-management drivers or Windows's built-in drivers for these "devices."  If Lenovo, have you found any way to disable Windows's drivers, or is that automatic?

 

Thanks for your very interesting posts!  Best Regards -- JCW2

Looks like all of the drivers are Microsoft.  The drivers themselves all carry dates like 2006, so the problem may not have been the drivers, but perhaps some interaction between them and 1903.  Who knows?  The problem hasn't recurred.

FYI, this worked for me also, although in the process it reversed the roles of "Battery 1" and "Battery 2!"  Makes it seem as though these Windows designations don't mean much... -- JCW2

Glad it worked for you.  As I said, I haven't had much trouble with the current evolution of Win10, but it was frustrating for a while.
