Lenovo ThinkBook 16 Gen 7 Intel Core Ultra 5 125H USB-A Not Charging Devices Fix

The Lenovo ThinkBook 16 Gen 7 includes USB-A ports for connecting peripherals and charging devices. However, some users find that phones, tablets, and accessories plugged into the USB-A port receive no power or charge very slowly, even when the laptop is on and plugged in.

This guide explains the common causes and fixes for USB-A not charging devices on the Lenovo ThinkBook 16 Gen 7 with the Intel Core Ultra 5 125H processor.

Common Causes

• USB Power Delivery disabled in BIOS or Lenovo Vantage
• Chipset or USB controller driver not installed or outdated
• Windows USB selective suspend cutting power to idle USB ports
• Power plan set to Power Saver, reducing USB port output
• Defective USB port or cable

Step-by-Step Fixes

Fix 1: Enable USB Power Delivery in BIOS

Lenovo BIOS includes settings that control USB charging behavior:

1. Restart and press F1 or Enter > F1 to enter BIOS.
2. Navigate to Config > USB.
3. Enable USB UEFI BIOS Support and Always On USB if available.
4. Save with F10 and restart.

Fix 2: Update the Intel Chipset and USB Controller Driver

The USB-A ports depend on the Intel chipset USB controller for power management:

1. Open Device Manager and expand Universal Serial Bus controllers.
2. Right-click each USB controller entry and select Update driver.
3. Also visit the Lenovo support page and download the Intel Chipset driver for the ThinkBook 16 Gen 7.
4. Install and restart.

Fix 3: Disable USB Selective Suspend

Windows can suspend power to USB ports that appear idle:

1. Open Control Panel > Power Options.
2. Click Change plan settings > Change advanced power settings.
3. Expand USB settings > USB selective suspend setting.
4. Set both On battery and Plugged in to Disabled.
5. Click OK and test USB charging.

“Enabling Always On USB in BIOS was the fix. My phone was not getting any power from the USB-A port when the laptop screen was off.”

Fix 4: Change the Power Plan

Power Saver mode can reduce USB port output current. Switch to Balanced or High Performance in Control Panel Power Options and test whether charging resumes.

Fix 5: Test with a Different Cable and Port

Try a different USB cable and a different USB-A port on the laptop if available. Some cables have very thin power wires that limit current, and a single port may be faulty while others work normally. If only one port is affected, hardware service may be needed.
