Hello,
 
Lately the battery on my computer has been acting up. I'll be working on my laptop unplugged and all of a sudden it will shut down. This will happen when the battery reads half full. I can start it up again by plugging it in. I leave it plugged in for a couple minutes and then unplug it just to check what percentage it reads. Indeed, it continues to read about 50% full (or a variety of values far above 0%).
 
I'm wondering if there's a problem with the battery driver. How would I do repairs or diagnostics on the battery driver?
 
I've got Windows 10.

Your battery is probably going bad. You can do a battery report showing the charge capacity vs it's design capacity.

If the command fails it may be because of powershell. If you see powershell as admin vs command prompt you can change to command from powershell.

Thanks JonhC,

 

Here's a link to the report:

What can you make of it?

 

If you look at the "Battery usage" section, you can see a sharp drop at 7:05 on Jan 29. That's exactly when it happened. I opened my laptop at around 7:05 and after about 6 or 7 minutes (6 min and 45 sec according to the table) it spontaneously dropped by 73%. That's exactly what I experienced.

 

What does this mean?

From the report your battery is good. I think your shutdown problems are due to something else.

 

Look at your 2018-01-29 date. The battery was drained by 73% in just under 6 minutes. I can't explain that. You may want to check your event logs during that time to see what you were doing.

 

Edit: I PM'd a moderator will hardware experience and it was suggested you may have a short in one of the battery cells which would give you that  large discharge rate. If you cannot borrow an identical battery, run the computer without a battery and see if the computer shuts itself down which would indicate a PSU or heating problem.

Thanks John,

 

That makes sense.

 

I've never had this shut down issue with the laptop plugged in, which is the majority of the time (though I haven't tried with the battery removed). I think your idea of getting an identical battery and seeing if the problem persists is a good idea as well. That will tell me for sure whether it's the battery or the computer.

 

Thanks.
