Hello everyone! My name is Kevin and I've had my Lenovo Y410P for a little less than 2 years.
So recently I downloaded Battery Bar as I was realizing that my battery duration was slowly receding.
Battery Bar, a program that shows battery level and wear, stated that my 6 cell battery had experienced 54.3% wear. I browsed the internet for specific tips on how to increase my battery duration and came upon battery recalibration. I tried it a couple times manually, but I didn't get any results.
So, I then turned to the battery gauge full-charge/discharge function in my Energy Management. After running that through the night, I realized the next morning that the battery was depleted and I couldn't turn on my laptop or even charge my battery unless I followed the steps:
- Remove the battery from the laptop.
- Plug in the AC adapter and use the laptop without a battery.
- The battery can be reattached. The battery is able to start charging.
- If I remove the AC adapter for a second and reattach it, it will not be recognized and it will not charge the battery.
As of now, Battery Bar shows that I have 0% wear of 52,830 mWh which is significantly less than the full capacity of a 6 cell battery; however, it's still better than what I had before. Anyways, does anyone else have this problem? And if you have, how did you resolve this issue? Thank you!

Hi whyskevin1 ,
Welcome to the Community Forums.
Battery calibration would just attempt to reallign capacitive elements of the battery to at least get out remaining usable charge but as the battery is known as a consumable part , it would soon deteriorate eventually and a lasting fix would be batery replacement itself.
You can try running a battery report from the command lines for further details.
Update us how things go .

Hello! Thank you for the welcome.
I ran the battery report, and in these attached photos, you can see how my battery levels were portraying some odd capacities. My battery works fine now, but my main issue is that my laptop is unable to detect my AC adapter unless I plug it in first without the battery and then with an inserted battery. Is this a common issue? Can anyone point me to a solution?? Thanks!
I conducted the Lenovo Energy Management: Battery Gauge Reset the night of the 23rd.

Hi whyskevin1 ,
Manual battery calibration like allowing the battery to drain off without being connected to the laptop then charging it after to full. As thing would also have the battery cool off and settle down a bit.
Then following the power checkout and testing both ac adapter for battery operational charging as prescribed in the manual (page 21-22) .
As AC connection not being detected when battery is in maybe causing issue itself on how power is being channeled (like battery being the trigger) . Not unless that we have another good battery to test it with can we be conclusive and as of the moment it would be worth a try to refresh the BIOS since design capacity are still within acceptable limit.
You can have it check with any local service center or call in technical support for service recommendation.
