How I Checked My Lenovo Laptop’s Battery Health 

Back in August, I checked my brother’s Lenovo laptop warranty and, yeah, bad news: it had already expired. I told you guys. 

But I didn’t tell my brother because I knew he’d probably hit me with, “Let’s just get a new laptop then.” No thanks, my wallet wasn’t ready for that.

Fast forward to now, and he tells me his battery has been draining way too fast. The moment he said that, I remembered, “Man, this thing isn’t even under warranty anymore.”

So, let’s check its battery health and see what’s actually going on. And I’m genuinely doing this for the first time, so I’ll tell you everything I figure out. 

Stick around, and while you’re at it, check your own battery too. You don’t want to get hit with an unexpected expense later, like I have a feeling I’m about to.

The first method I’d suggest, and Lenovo also officially tells you to do, is using Lenovo Vantage. You might already have it installed, but if not, just install it. I didn’t have it either, so I installed it, and it worked perfectly for me.

• Open Lenovo Vantage. I couldn’t remember where mine was, so I just searched for it from the taskbar.

• Go to Device Settings > Power, and you’ll see your battery temperature, health status, capacity, and other details. 

• For the full picture, click View All under the “At a Glance” section.

And that’s it. However, one thing I discovered while doing this was the Battery Gauge Reset. Scroll down to the charging section, and you’ll find it there. 

Lenovo says using this feature periodically can help improve the battery’s lifespan. I had no clue about this either, so I’ve just enabled it myself. Let’s see if it actually helps. 

Bro, I was actually a little relieved when I checked mine. The full charge capacity is 38.86Wh, while the original design capacity is 45.01Wh, so that leaves me with around 86% battery health. 

And that’s not bad at all. Usually, once it drops below 80%, that’s when the battery starts showing its age. Mine is still above that, so thankfully, things aren’t looking as bad as I thought.

Okay, I’ll be real with you the first method was way easier. With this one, halfway through I was like, “Bro, what am I even doing?” But if Lenovo Vantage doesn’t work for you, this method can save the day.

• Search for Command Prompt from the taskbar, right-click it, and select Run as administrator.

• Then type: “powercfg /batteryreport”

• Hit Enter, and it’ll give you the location of an HTML battery report, probably somewhere on your C drive.

• Do some hard work and open that location in File Explorer, find the file, and open it in your browser. 

• You’ll get all the battery details there.

Yeah, it takes a little digging, but when nothing else works, you take what you can get. I actually found this method on ASUS’s website and then saw something similar in Microsoft’s guide, so I gave it a shot. Surprisingly, it worked perfectly fine on my Lenovo too.

Either way, my brother’s battery is still doing okay, so thankfully, we can squeeze a few more days out of this laptop.

Let’s be fair, the Command Prompt report is probably more trustworthy than any third-party tool. But there’s a reason I tried this one.

Whenever I take a laptop in for repairs, I’ve noticed the guy uses a tool called BatteryInfoView to check battery health. So I thought, if repair guys actually use it, why not give it a shot myself?

• BatteryInfoView is provided by Nir Sofer on the official NirSoft website.

• Just open the site, scroll down, and you’ll find the download option for your OS.

• It downloads as a ZIP file, and there’s really nothing complicated here. Open it, find the application file, right-click it, and hit Run. 

• Your battery details should pop up right away.

Luckily, it showed almost the same battery health as the other methods. So yeah, I’m done checking it over and over. The battery is fine, my brother’s laptop can keep going, and my wallet gets to survive another day.
