Some of the most tedious things that can happen to your laptops are related to their batteries. Indeed, batteries are one of the most delicate parts of a computer. Lenovo laptops are no exception; that’s why you may need a proper online Lenovo laptop battery troubleshooting method.
We have compiled a list of cases along with specific solutions for your consideration. Are you eager to know? Let’s get the ball rolling!
Lenovo Laptop Battery Troubleshooting
#Case 1: Battery Charges Extremely Slow
Sometimes, you may find out that even if you turn off your computer and leave it plugged in, your battery does not seem to charge at all. It can be due to what the manufacturer calls “over-discharged.”
It means your battery level is so drained that regular charging can be prolonged as if it doesn’t charge.
In this case, please do as follows:
- Shut down your PC
- Make sure the power unit is correctly connected to the computer
- Connect the AC adapter
- Turn on the Quick Charger function if your laptop has it
At this point, please leave it to charge for at least 24 hours. If your battery is not 100% after that time, it might be broken, and you should consider buying a new one.
#Case 2: False Indicator
The battery level indicator in your PC sometimes can run into trouble too. One of the most common errors is the “false level indicator,” which shows a wrong percentage.
It should come clear that your computer has a false indicator if it has the following signals:
- It still operates at a 0% battery level
- Your laptop suddenly goes out when the battery is not empty
- The battery is 100% but experiences an unexpectedly short runtime (false peak)
In any case, you should discharge your power unit entirely and then recharge it. In the “false peak” case, if your computer still has shorter runtime than usual, you should bring it to service or replace the power unit. In the meantime, try using it without a battery.
#Case 3: Defective AC Adapter
The trouble might not come from the power unit but an external device such as the AC adapter.
To check if this is true, please try plugging in your computer with another compatible AC adapter. If it still charges as usual, then it’s your sign.
Before that, please make sure that you correctly connect the adapter to the charger port. Try wiggling the cord at the connection point to see if it’s fully plugged.
Also, take a look at the power outlet and cross-check if it works without issues. If the indicator light on your power box or the AC adapter does not turn on when plugging in, consider removing it and having a new one for good.
#Case 4: Dirty Or Defective Connection
Working in a dusty environment can let debris and dirt build up around and inside your computer. The charger port is susceptible to this issue, and debris can block electricity transmission, leading to poor charging ability.
Try unplugging your AC adapter, then use a clean, dirt-free Q-tip or toothpick to clean and remove any dirt you find around and inside the charger port. Reconnect the charger and try again.
Another case is when the connection between the power unit and the motherboard is broken. This situation is out of hands with most regular users, so you must bring the device to a repair service to fix it.
#Case 5: Regular Wear And Tear
The engineering boundaries limit the lifespan of a battery. In most cases, its chemical components will wear out after the first 2-3 years of regular use. If you are lucky, that means a few hundred cycles of charging (a cycle is any given 100% used by the laptop).
After experiencing tremendous abuse from users, some power units can last no longer than 5 minutes at the end of their lifecycle. Some cases are even worse when your PC can’t operate without the AC adapter plugging in.
Wear and tear is a normal process of electrical devices, and you should expect it. Remove the old power cells, handle them with care and give your computer a fresh new pack.
Check if the PC has one of the above software installed.
For example, you can access Lenovo Energy Management through the Start window > All Programs. From there, you can check the battery’s health.
In case your device doesn’t have designated software, download Lenovo Diagnostics from here.
#Case 6: Lenovo Laptop Prevents Charging Over 60%
There’s a saying that goes, “It’s not a bug, it’s a feature.” Sometimes the features that boggle our mind the most are supposed to help the machine perform better. If your computer refuses to charge over 60% or any certain % in any case, this feature is to blame.
The Lenovo Energy Management feature stops your power unit from receiving power after a certain threshold. Other names for this function vary with brands. Some for Lenovo are “Vantage Lenovo” or “Lenovo Power Manager,” amongst others.
To fix this:
- Navigate to Start > All Programs > Lenovo
- From there, select Energy Management, proceed to Power Management Options
- Then, turn off the Conservation Mode
If the PC is installed with Vantage Lenovo, go to Device > My Device Settings > Battery. From there, turn off the Conservation Mode or Custom battery charge threshold to Off .
#Case 7: “Laptop Battery Not Genuine”
Lenovo PC has a feature that detects and alerts if you are not using an OEM (Original Equipment Manufacturer) power unit but instead a 3rd company’s pack. Check with the supplier if your new power cells are legitimate to use for Lenovo laptops.
Nevertheless, if your battery is legitimate but does not function correctly, try updating the system BIOS regarding your device model number.
Once updated your BIOS, please follow the user’s guide for your new power cells to use it correctly.
Last but not least, make sure that your newly purchased power unit is compatible with your PC model. Online purchasing can lead to some misunderstandings, so consult your sellers carefully on this.
Regardless of how robust or effective your electronic devices are, there always comes a time when everything can go wrong without your fault. As a user, it can be challenging to conduct a diagnosis.
We hope that our Lenovo laptop battery troubleshooting tips are enough to help with your confusion. To conclude, your device is up to your considerations, so please always bring it to a reputable service if any issues are not under your control.
