X1 Tablet & Prod Module Battery Failover not Working

2016-05-27, 14:38 PM

I have an X1 Tablet and the Productivity Module.  Windows 10 recognizes Battery 1 as the internal battery and Battery 2 as the Productivity Module's battery.  When running the system from battery, the Productivy Module is drained first, but the problem is that once it has drained the X1 Tablet completely powers off and won't turn back on unless you disconnect the Productivity Module. 

 

In other words, it is not automatically failing over to the X1's internal battery once the Productity Module's battery has drained.  I've installed the following:

 

X1 BIOS 1.18

Lenovo Power Management Driver 1.67.11.8

 

Is there a setting I can change to fix this issue?  Or is there a newer piece of software / firmware that will address the issue?

 

 

 

 

Solved! See the solution

You should definitely contact Lenovo Support about this. But a question - if you remove the productivity model when the machine is running, does it crash/power off as well>

Hi Guru,

If Windows indicates that Battery 2 (prod module) is in use, and you remove it when the machine is running, then it does crash.  We'll contact Lenovo Support and see if they have any ideas, because it seems to me that it should automatically switch over to the internal Tablet battery.

 

I'll post any news to this thread as I find out more info.

 

Thanks,

Ryan

Absolutely it should switch, that confirms an issue. This could be a simple BIOS glitch.

 

BTW, "TT137" is my handle, not "Guru" which is just my user status. :smileywink:

I have a similar issue, however, mine only happens when the battery in the productivity module gets drained. As soon as that happens the tablet powers off hard/abrubtly and I lose all data that I had been working on. However, removing the module while it still has power does not cause the issue.

 

I opened a case with Lenovo and am waiting to hear back from them. Have you gotten any update since you faced this issue?

 

Thanks in advance!

kozunak,

I was previously mistaken about removing the module.  Removing it only causes an issue when it is drained past 6%.

 

As a follow-up, we received a second X1 Tablet & Productivity Module and it exhibits the same issue as the first unit.   

 
I can make this happen around 80% of the time, but sometimes it does fall over to the X1 Tablet's battery properly.  Here are the steps I take to reproduce it:
 
1.  Charge the X1 Tablet and Productivity Module batteries to full capacity.
 
2.  Use the device until the Productivity Module battery is near 8% capacity, then start paying attention.
 
3.  When the Prod Module capacity hits 5-6% capacity, then the system(s) either completely power off or goes into a BIOS rebooting loop.   *If it doesn't crash the first time, then charge the prod module for 5 minutes until it gets about 8% charge, then disconnect AC power and test again.  Sometimes it takes 3 or 4 times of trying before I can get it to crash consistently.
 
4.  The Windows Event log does not contain any crash details except for an entry after the next successful boot which says "Kernel-Power The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

 

I too have opened a case with Lenovo and I'm told that they are looking into it now.  I'll post a follow-up once I hear further on my case.

Thank you for the reply! My issue is similar to yours as it does not happen 100% of the time. However, I can definitely replicate it every 2nd or 3rd time.

 

I also noticed that when the battery failover happens without a crash the screen flickers several times so there is definitely something not right there.

 

The fact that it also happens with your replacement unit is concerning but I hope that it is fixable with a BIOS update/patch.

 

I will also keep you posted if I hear back from Lenovo...my case is 304ZFG6. What is yours?

Quick Update from me:

I want to start by saying that I love the X1 Tablet but I simply hate Lenovo's support!!! I opened my case (304ZFG6) for a few days but nobody from Lenovo contacted me. So I finally decided to try reaching out to them today. Well I spent over 1 hour on chat while being trasnfered to different departments. Then I was advised that I need to call support directly. So I called them and the support person knew nothing about this product. After an hour on the phone with her she proceeded to tell me that I needed to speak to sales since the productivity module is an accesory and not a part that came with the tablet (Seriously???) I told her that this is crazy so she proceeded to transfer me to their "premium" support. Now, since the case was created with a different department, the premium support staff could not look it up so I had to explain everything from scratch only to be told that the premium support is not free and that I will need to pay in order to be helped out. Simply unreal...I am going to try to return this thing asap.

Did you ever get this resolved? I ended up returning my product but am interested to know what your outcome is.

 

Thanks!

Hi,

I'm continuing to work with Lenovo support, but I'll refrain from commenting while the case is still active.

Thanks
