Lenovo laptop battery will not charge
If the problem persists, the only option left is to replace the battery. This simple procedure can breathe new life into your laptop. To select the right battery, you’ll need either the old battery or the laptop model. For the former, you can find a compatible model on Amazon, while for the latter, the Zeto website is a reliable resource.
Ensure that the power supply (PSU) is securely plugged in and inspect for any signs of a damaged cable or exposed wires. Potential causes:
Battery Overheating: If the battery’s temperature surpasses the system’s threshold while the laptop is in use, the charge controller will automatically shut down the battery for safety. To verify this issue, allow the battery to cool down and attempt to recharge it.
Improper Battery Initialization (for removable batteries only):
- Turn off the laptop, unplug the charging cable, disconnect the battery, press the power button on the laptop for 20 seconds, reconnect the battery, plug in the laptop’s power supply, and power on the laptop.
- ACPI Driver and LENOVO Chipset: This pertains to power management on your LENOVO laptop:
- Navigate to Device Manager (via WIN+R, type “devmgmt.msc” for Windows 7, or right-click on “Start” in Windows 10/8).
- Under “Batteries,” look for “Battery with ACPI compatible Microsoft management.” Right-click and select “Remove.”
- Confirm the removal in the ensuing window.
- Restart your laptop.
If the battery charging issue arises after reinstalling the OS, it might be related to non-original power and chipset management drivers from the manufacturer. In this scenario, visit the official LENOVO website, download, and install drivers tailored to your model.
Outdated BIOS (UEFI): Before updating, consider resetting it to factory defaults using the Load Defaults option in BIOS settings. If this doesn’t resolve the problem, locate the latest BIOS version in the Support section of the official website.
Laptop Charge Controller Malfunction: In this situation, a replacement is necessary.
LENOVO Battery Chip Failure: Repairing the battery with a chip replacement is an option, though it may not always be feasible, particularly with older laptops, as the chip would need to be flashed to match your model. Alternatively, you may opt to replace the battery itself.
Ensure the power supply (PSU) is firmly connected to the socket, and check for any signs of a damaged cable or exposed wires.
Battery Overheating – Causes
This issue typically arises when the cooling system hasn’t been properly maintained. Dust accumulates, causing the battery, and subsequently the entire device, to overheat. It can also occur if the laptop is used in confined or dusty environments. In warmer seasons, this is often a leading cause of charging troubles.
How do you identify overheating? The device will initially charge normally, but after a while, you’ll see a “not charging” message. This is a clear indicator of overheating. The primary solution is to have the device cleaned of dust, which is best done by a professional in laptop maintenance.
Additionally, specialized laptop stands can aid in preventing overheating. They assist in overall device cooling, thereby prolonging its lifespan.
LENOVO notebook does not indicate battery charge
This issue might arise due to the presence of additional (third-party) programs on the laptop that haven’t undergone thorough debugging by their developers. For instance, on the lower right side of the screen, there’s a standard Windows widget for monitoring battery levels.
However, it’s possible that you’ve inadvertently installed a similar utility with extra features. You might not even realize that it could be causing a problem.
To revert to the original state, navigate to “Start”/”All Programs”/”Control Panel”/”Programs and Features.”
Locate the problematic program in the list and click “Remove.” Opt to completely remove it from your PC, don’t just “change” it. The official program should immediately resume its function, visible in the familiar spot at the bottom left corner of the tray. Your battery should now function properly, and the error should be resolved!
LENOVO battery does not charge to 100%
This situation can occur if the laptop itself imposes a limit on the battery charge, capping it at less than 100%. Manufacturers believe this restriction positively impacts battery longevity. (You can deactivate this mode by going to: Start / All Programs / Power Management / Battery Services).
Alternatively, you may need to reset the BIOS:
- Press Del+Esc or Del+2 during laptop boot-up.
- Look for “Load BIOS Default” in the options.
- Highlight “Y” and press Enter to confirm the reset.
The message “Plugged in, not charging” may also appear when the battery charge drops below 100% after prolonged use of the laptop on AC power, essentially functioning like a desktop computer. The rationale is simple – the battery is charged to full, the laptop disconnects from charging but maintains its current level display. Over time, the charge might dip to 99.98%, and so on. To confirm that everything is functioning as it should, unplug the power adapter and plug it in again.
Battery charge does not reach 100%
Many laptop manufacturers design and incorporate specialized software into their devices for monitoring and managing battery usage and status. Often, these “optimizers” are the culprits behind incomplete charging.
These utilities typically operate in two modes, with the first aimed at conserving energy and preventing the battery from reaching full charge. Switching to the second mode should restore a 100% charge. If all else fails, consider disabling or completely removing the utility.
If none of the above procedures resolve the issue, it may be attributed to natural wear and tear of chemical components, controller malfunctions, or oxidation of contacts. In such cases, professional intervention may be required.
The battery LENOVO is empty and doesn’t charge anymore
Defective battery: The battery or battery controller is dead (the charge indicator lights up but the percentage of charge does not increase). Replace the battery or faulty battery cell.
- The power supply is defective or the cable is disconnected. (The notebook does not indicate that the power supply is connected and does not charge the battery.) Replace the power supply.
- If the notebook is dusty or overheated, battery charging might be slowed down. Remove any dirt and replace the thermal paste.
