Lenovo Yoga Slim 7 Pro USB-C Not Charging Windows 11: Vantage and Driver Fix

Lenovo Yoga Slim 7 Pro is a sleek productivity laptop that charges via USB-C Power Delivery. On Windows 11, the USB-C port stops charging the battery — plugging in a USB-C charger shows the connected icon but the battery level does not increase, or a warning appears that the charger may not support full power delivery. The laptop drains even when plugged in during use. I have resolved USB-C charging issues on Yoga Slim 7 Pro units and this guide covers every verified solution.

Why Lenovo Yoga Slim 7 Pro USB-C Not Charging Windows 11

USB-C Charger Not Meeting Yoga Slim 7 Pro Power Delivery Requirements

Yoga Slim 7 Pro requires a USB-C Power Delivery charger capable of at least 65W at the correct voltage profile. Budget USB-C chargers may advertise 65W but negotiate at lower voltage levels that the Yoga Slim 7 Pro PD controller does not accept for charging. The laptop connects the charger but the PD controller rejects the negotiated profile, resulting in no charging. The USB-C port functions for data and video output but the battery does not charge. Using a Lenovo-verified 65W USB-C PD charger that correctly negotiates the 20V profile solves charger-specific issues.

Lenovo USB-C Charging Controller Driver Not Recognizing Power Delivery

Yoga Slim 7 Pro USB-C charging uses an Intel Thunderbolt controller combined with a dedicated USB Power Delivery controller. Windows 11 requires both the Intel Thunderbolt driver and the USB PD controller driver to be at current versions for charging negotiation to work. If either driver is outdated or corrupted by a Windows Update, the charging negotiation fails silently — the USB-C port shows connected but PD charging capability is not established. Updating both drivers restores PD charging.

Lenovo Vantage Battery Conservation Mode Blocking Charging

Lenovo Vantage includes Battery Conservation Mode which caps battery charging at 60 percent to prolong battery lifespan. When this mode is enabled, the laptop stops charging when the battery reaches 60 percent and will not charge above that level even when plugged in. Users who see charging stop at 60 percent every time are experiencing Conservation Mode behavior, not a hardware fault. Disabling Conservation Mode in Lenovo Vantage immediately allows the battery to charge to 100 percent.

How to Fix Lenovo Yoga Slim 7 Pro USB-C Not Charging Windows 11

Step 1 — Check Lenovo Vantage Battery Conservation Mode

Open Lenovo Vantage and go to the Power section or Battery settings. Look for Battery Conservation Mode or Charge Threshold. If Battery Conservation Mode is enabled, toggle it off. The battery should immediately begin charging above 60 percent when a charger is connected. Also check for a custom charge threshold that may have been set — some Vantage versions allow setting a custom upper charge limit between 60 and 100 percent. Set the threshold to 100 percent for full charging capability. Test by connecting the charger and watching the battery percentage increase.

Step 2 — Verify USB-C Charger Power Delivery Capability

Connect the USB-C charger and wait 30 seconds. Right-click the battery icon in the taskbar and check if it shows Plugged in charging or Plugged in not charging. If it shows not charging, go to Settings, System, Power and sleep, Battery and look for a warning about the connected charger. The warning will indicate if the charger is insufficient for the laptop. Try a different USB-C charger rated at 65W or higher that supports USB Power Delivery 3.0 with 20V output. Lenovo’s own 65W USB-C slim tip adapter is the reference charger that always works correctly on Yoga Slim 7 Pro.

Step 3 — Update Intel Thunderbolt and USB Controller Drivers

Go to Lenovo support page and search for Yoga Slim 7 Pro with your machine type. Under Drivers and Software, find the Intel Thunderbolt Driver and the USB PD Controller Driver in the Chipset or Power Management section. Download and install both. Also open Lenovo Vantage and check for any pending hardware driver updates under the Device section. After installing driver updates, reboot and connect the USB-C charger. The charging indicator in the battery icon should now show charging. If the issue persists after all three steps, the USB-C port hardware may require service.

My Yoga Slim 7 Pro stopped charging via USB-C out of nowhere. Opened Lenovo Vantage and found Battery Conservation Mode had been turned on somehow — it was capping the battery at 60 percent. Turned it off and charging resumed immediately. Check Vantage first before assuming there is a hardware problem. — Susan C., Lenovo Community

Frequently Asked Questions

What USB-C charger wattage does Lenovo Yoga Slim 7 Pro require?

Yoga Slim 7 Pro requires a minimum 65W USB-C Power Delivery charger for normal operation while running. A 45W charger will charge the battery slowly or only when the laptop is in sleep or off. A 65W PD charger at 20V is the recommended minimum. Higher wattage chargers like 90W or 100W also work and provide faster charging. The laptop does not accept more wattage than its controller allows — excess wattage is not harmful.

Can Lenovo Yoga Slim 7 Pro charge from both USB-C ports?

Yoga Slim 7 Pro typically has two USB-C ports — one Thunderbolt 4 and one USB 3.2 Gen 2. Both usually support Power Delivery charging, but the Thunderbolt port generally provides faster charging as it has higher power delivery capability. If one port does not charge, try the other. Check the specifications for your specific model to confirm which ports support PD charging as configurations vary by region and configuration.

Does Lenovo Yoga Slim 7 Pro support reverse charging other devices via USB-C?

Yes. Yoga Slim 7 Pro supports reverse charging — it can output power via USB-C to charge phones, tablets, and other small devices. This works when the laptop is on and connected to AC power or when running on battery. The laptop prioritizes its own charging when connected to an AC charger and simultaneously charges connected devices within the port’s output power limit.

Why does Lenovo Yoga Slim 7 Pro show plugged in but not charging with a known-good charger?

This can occur if the Lenovo Battery Firmware needs updating. Open Lenovo Vantage, go to Device Settings, and check for a Battery Firmware Update under system or power settings. An outdated battery firmware can cause the charging controller to reject valid PD profiles. Install any battery firmware update and reboot. Also check if the charging cable rather than the adapter is the issue — USB-C cables have different current ratings and a cable rated for only 3A may limit PD charging on a 65W charger that requires 5A for full wattage.

Conclusion

Lenovo Yoga Slim 7 Pro USB-C not charging on Windows 11 is caused by Battery Conservation Mode capping charging at 60 percent in Lenovo Vantage, the USB-C charger not meeting the 65W Power Delivery 3.0 at 20V requirement, or outdated Intel Thunderbolt and USB PD controller drivers preventing charging negotiation. Check and disable Battery Conservation Mode in Lenovo Vantage first as this is the most common cause, verify the charger is a 65W or higher USB-C PD 3.0 compliant adapter, and update both the Intel Thunderbolt driver and USB PD controller driver from the Lenovo support page. Battery Conservation Mode being silently enabled accounts for most Yoga Slim 7 Pro charging complaints after Lenovo Vantage updates.
