Lenovo Yoga C640-13IML Won’t Turn On

If your Lenovo Yoga C640-13IML doesn’t power on—no lights, fan noise, or display—this page will help you troubleshoot the issue and determine what steps you can take to get your device working again.

If your laptop doesn’t respond at all when you press the power button, the battery might be empty. Plug in the charger and wait at least 15–30 minutes before trying again. If there’s still no response, try a different charger or outlet to rule out charging problems.

If the charging light doesn’t turn on, there could be an issue with the charger or charging port. Inspect the charger cable and adapter for damage. If possible, test with a known-working charger. Also check the charging port for debris, loose connections, or signs of wear.

Sometimes, the system can become unresponsive due to a power state glitch. Disconnect the charger and all accessories. Then press and hold the power button for 10–15 seconds to force a reset. Plug the charger back in and try turning the device on again.

If the internal battery connector is loose or not properly seated, the laptop may not power on even when plugged in. Opening the device and reseating the battery connector may resolve the issue.

If your battery has been damaged or it is at the end of life, follow this battery replacement guide.

If there are no signs of life—no charging light, no fan noise, no screen backlight—the motherboard or power button may have failed. Diagnosing this requires further disassembly or professional repair.

A corrupted BIOS or firmware can prevent the laptop from turning on. If your model has a small pinhole reset (Novo button), use a paperclip to press it and access recovery options. If available, select BIOS Setup and restore factory defaults.
