z410 Battery Guage Reset Issues

Hi Everyone, 

 

So after a few months of use with my z410 I decided to take the Energy Manager's (program) advice and preform the suggested Battery Guage Reset. 

 

After the reset I have had a terrible experience. The z410 will at times not boot up on battery alone, and when I plug the charger in it will tell me the battery is dead, but shorlty after it everything is running it will tell me i have 100% battery. Now - if I were then to "pull the plug" the computer will act normally and get great battery perfromance...HOWEVER - if I plug ghe charger back in, the battery drops back down to 0%.

 

I don't know what to do - please help...I can't win right now with this computer. I love it, but can't trust it. 

 

Please advise - please, and thank you!

Hi shoosh1,

 

Welcome to Lenovo Community Forums!

 

Turn OFF the computer.

Remove the AC charger

Press the OKR Button

Once the scren powers up , Stay on that screen and let the computer overnight on that screen until it turn itself off because of power loss in battery.

 

Now plug the AC back and charge it till 100%

 

Let me know if this worked for you

Thanks

Solid Cruver

Re: z410 Battery Guage Reset Issues

I have struggled with the same problem. My battery went faulty just 2 weeks after the warranty period. I approached the service center who said the battery needs to be replaced. I replaced the battery only to find that 5 months, I faced the same issue once again.

 

After reading and doing lots of research, and trying a hell lot of things, I finally tried reinstalling the battery firmware which I got from the link :
https://download.lenovo.com/lenovo/content/sm/z500_z510_battery_firmware_update.zip

 

Go through the README file in the zip before running the application.
Please note that this works ONLY on the original battery. The replacement battery I bought was not original Lenovo battery(as it was not available in my region). Hence, the firmware upgrade will fail to proceed with the process.

 

So I put back my original (supposedly faulty battery!) and tried the firmware upgrade and it worked!
Now I'm back to using my laptop with atleast 2.5 to 3 hours of battery backup on the old original battery (which the service center guys told me was damaged!) for the past 3 months with no problems.

 

 

Dear Lenovo Team, its a disaster that you people are not able to provide proper diagnosis and solution to this KNOWN problem , widely faced by a lot of customers. I spent a considerable amount of time, effort and money for absolutely nothing, just to realize that it had nothing to do with any hardware!

And we're back...
