Lenovo Yoga C640-13IML Not Charging

If your Lenovo Yoga C640-13IML doesn’t charge when plugged in—no charging light, battery percentage stuck at 0%, or unexpected power drain—this page will help you figure out what’s wrong and how to fix it.

A damaged power adapter or USB-C cable is a common cause of charging problems. Inspect the entire length of the cable for fraying or exposed wires. Try using a known-working charger that meets the laptop’s power requirements. If the charging light turns on or the battery icon changes, your original charger may be faulty.

If the charger is working but nothing happens when it’s plugged in, the port itself may be loose, dirty, or damaged. Inspect the charging port with a flashlight—look for dust, bent pins, or signs of wear. Gently clean the port using a can of compressed air. If the port feels wobbly or doesn’t securely hold the cable, it may need repair or replacement.

Sometimes, charging problems can be caused by a corrupted battery or power drivers. Open Device Manager and look for “Batteries.” Right-click and uninstall both the “Microsoft AC Adapter” and “Microsoft ACPI-Compliant Control Method Battery” options, then restart your laptop. Windows will reinstall the drivers automatically. Also, check for BIOS updates on Lenovo’s support website.

If your laptop only works when plugged in but instantly shuts off when unplugged, the internal battery may be dead. A worn-out battery may also charge slowly, get stuck at a certain percentage, or fail to hold a charge. If your laptop is more than a couple of years old, a battery replacement may be necessary.
See the Battery Replacement Guide.

Power-saving settings or battery protection modes (like Lenovo’s “Conservation Mode”) can prevent the battery from charging fully. Open Lenovo Vantage or the BIOS setup and look for battery settings. Disable any mode that limits charging if you want the battery to charge to 100%.
