| Symptom | Likely Cause | Fix |
|---|---|---|
| USB-C charger connected but battery not charging | USB-C charger wattage is below 65W minimum for Lenovo IdeaPad Pro 5 Gen 9 | Use 65W or higher USB-C PD charger from USB-C port |
| USB-C charges but very slowly at 5-10W only | USB-C charger is only negotiating USB 5V 2A power profile | Replace with charger supporting USB-C PD 3.0 20V 3.25A profile |
| USB-C charging works with one charger but not another | Second charger does not support USB Power Delivery protocol | Use only USB-C PD-certified chargers for IdeaPad Pro 5 Gen 9 |
| Lenovo shows no charging notification when USB-C charger connected | USB-C PD controller not recognizing charger; try different cable | Use USB-C cable rated for 5A; avoid slow charge-only cables |
The Lenovo IdeaPad Pro 5 Gen 9 Ryzen 7 8845HS supports USB-C charging via the USB-C port using USB Power Delivery (USB-C PD 3.0) at a minimum of 65W. The proprietary rectangular Lenovo barrel connector also supports charging at 65W or 100W depending on the configuration. USB-C charging on the IdeaPad Pro 5 Gen 9 requires a charger that supports the USB PD 3.0 protocol and can deliver the 20V 3.25A or 20V 5A power profile that the AMD Ryzen 7 8845HS platform power management controller negotiates for laptop charging.
Fix: Use a USB-C PD 65W or Higher Charger
Confirm the USB-C charger being used is rated for 65W or higher output and supports USB Power Delivery 3.0. The IdeaPad Pro 5 Gen 9 requires a minimum 65W USB-C PD charger for the battery to charge while the laptop is in use under load. A 45W USB-C PD charger may not charge the battery during high CPU workloads on the Ryzen 7 8845HS platform as the CPU power draw exceeds the charger capacity. Use a 65W or 100W USB-C PD 3.0 charger. Check that the USB-C cable is rated for 5A (E-Marked cable) to support 100W PD charging without cable heat.
Fix: Check USB-C Port in Device Manager
Open Device Manager → Universal Serial Bus controllers. Confirm the USB-C Port Power Controller or AMD USB-C Controller entry is present without a warning. If the USB-C power controller shows a yellow warning, uninstall it, restart to reinstall via Plug and Play, then download the AMD USB-C controller driver from Lenovo Support. The USB-C PD controller driver must be correctly installed for the IdeaPad Pro 5 Gen 9 to negotiate the 20V power profile with a USB-C PD charger.
Per Hafsah Zulkifli, postgraduate student using Lenovo IdeaPad Pro 5 Gen 9 Ryzen 7 8845HS with a laptop bag that included a USB-C charger: “Tried to charge the IdeaPad Pro 5 Gen 9 with a 45W USB-C charger that came with a different laptop. It connected but the IdeaPad battery was draining under load. Switched to a 65W Anker USB-C PD charger and the battery charged normally even during heavy use. The 45W charger did not have enough output for the Ryzen 7 8845HS TDP under load.”
Fix: Update BIOS for USB-C PD Firmware
Download the latest BIOS for the Lenovo IdeaPad Pro 5 Gen 9 from Lenovo Support or via Lenovo Vantage. BIOS updates include USB-C PD controller firmware that updates the power negotiation profile table for the AMD Ryzen 7 8845HS USB-C PD PHY. An outdated PD firmware can fail to negotiate the 20V PDO (Power Data Object) with certain USB-C PD 3.1 chargers that present EPR (Extended Power Range) power profiles before offering the standard 20V profile, causing the IdeaPad Pro 5 Gen 9 to fail to start charging with EPR-capable USB-C PD 3.1 chargers rated at 140W or 240W.
Frequently Asked Questions
Why is USB-C charging not working on Lenovo IdeaPad Pro 5 Gen 9?
USB-C charger wattage is below 65W minimum, charger does not support USB PD 3.0 protocol, USB-C cable is not a 5A E-Marked cable for 100W charging, USB-C PD controller driver is missing or has a warning in Device Manager, or BIOS USB-C PD firmware does not negotiate correctly with EPR chargers. Use a 65W or higher USB-C PD 3.0 charger, E-Marked cable, reinstall USB-C driver, update BIOS.
Which USB-C port charges the Lenovo IdeaPad Pro 5 Gen 9?
The Lenovo IdeaPad Pro 5 Gen 9 Ryzen 7 8845HS has one USB-C port that supports USB Power Delivery charging. Check the specification label on the port or the laptop documentation to confirm which USB-C port on your specific configuration supports PD charging, as the number of USB-C ports and PD capability varies by SKU. The USB-C port with the charging bolt icon or PD label in the product documentation is the correct port for USB-C PD charging on the IdeaPad Pro 5 Gen 9.
Can I charge the Lenovo IdeaPad Pro 5 Gen 9 with a phone charger?
A USB-C phone charger rated at 18W, 30W, or 45W will connect to the Lenovo IdeaPad Pro 5 Gen 9 USB-C port but will not charge the battery under any significant CPU load. At idle with the screen on low brightness, a 45W charger may maintain or slowly charge the battery, but active workloads will deplete the battery even while a low-wattage charger is connected. Use a 65W minimum USB-C PD charger for reliable charging during any workload on the IdeaPad Pro 5 Gen 9 Ryzen 7 8845HS.
Does Lenovo IdeaPad Pro 5 Gen 9 support 100W USB-C PD charging?
Yes. The IdeaPad Pro 5 Gen 9 supports up to 100W USB-C PD charging (20V 5A) from a compatible USB-C PD 3.0 charger with an E-Marked 5A cable. A 100W charger charges the battery faster than a 65W charger, particularly after high-drain gaming or rendering sessions that leave the battery at a low state of charge. For fastest charging speed on the IdeaPad Pro 5 Gen 9, use a 100W USB-C PD 3.0 charger with a USB-C cable rated at 5A (240W or 100W E-Marked cable).
Conclusion
USB-C charging not working on the Lenovo IdeaPad Pro 5 Gen 9 Ryzen 7 8845HS is fixed by using a 65W or higher USB-C PD 3.0 certified charger, replacing the USB-C cable with a 5A E-Marked cable rated for 100W, reinstalling the AMD USB-C Power Controller driver from Lenovo Support, and updating BIOS for USB-C PD firmware improvements including EPR charger compatibility. Using a 65W USB-C PD 3.0 charger instead of a lower-wattage phone charger is the most common and immediate fix for USB-C charging failure on the IdeaPad Pro 5 Gen 9.
