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- Chipset or USB controller driver not installed or outdated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:
- Restart and press F1 or Enter > F1 to enter BIOS.
- Navigate to Config > USB.
- Enable USB UEFI BIOS Support and Always On USB if available.
- 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:
- Open Device Manager and expand Universal Serial Bus controllers.
- Right-click each USB controller entry and select Update driver.
- Also visit the Lenovo support page and download the Intel Chipset driver for the ThinkBook 16 Gen 7.
- Install and restart.
Fix 3: Disable USB Selective Suspend
Windows can suspend power to USB ports that appear idle:
- Open Control Panel > Power Options.
- Click Change plan settings > Change advanced power settings.
- Expand USB settings > USB selective suspend setting.
- Set both On battery and Plugged in to Disabled.
- 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.
