Charging Being Weird?

Question

Hello! I've had my computer since December 25th, 2025, but it's been acting up with charging. When I plug it in, it'll charge for a bit, then stop randomly and start again a second later? I don't know why this is happening, I have a LX15PRO Laptop, Windows 11 Pro, which seems decently recent, so I'm pretty confused onto why this is happening. It's rarely, if ever fell, doesn't have dust, and nothing is stuck in the charger port to prevent a charge. I'm not sure if this is a problem with the charger or my computer, as it isn't any of my outlets. Please help!

Answer 1

Hi Nooby Jack,

If this is a software issue, please update your BIOS to the latest version and double-check if there's a manufactural charging utility application that can interact with the charging progress.

Otherwise, this could be hardware issue. Please charge your laptop with another socket, another charger.

If your laptop is currently under warranty, please send it to service center for further troubleshooting.

I hope that above information is helpful to you.

Open Device Manager (accessible by right clicking your Start Button)

Expand the Batteries section

For each device in that section:

Right click and choose Disable

Wait a second or two, then right click and choose Enable

Close Device Manager

Restart (not shut down) your laptop then check if it is charging correctly.

If not, start your laptop and on the Lenovo screen repeatedly press F10 or F12, then in the Lenovo UEFI, select Apps and run the Lenovo Diagnostics from there to test if it indicates any problem with the battery or power board.

Answer 3

Intermittent charging (plugged in, then briefly not charging, then charging again) is commonly caused by the charger, cable, or port not consistently meeting the power requirements of the device, even if the laptop and Windows version are recent.

Based on the available information, the following are the most relevant checks and actions:

1. Verify charger and cable

• Use the original charger and cable that came with the laptop.
• If using a third‑party or USB‑C charger, it may not meet the laptop’s power requirements or may not support the correct USB Power Delivery profile. A charger that provides lower voltage or amperage than required can cause unstable or slow charging.
• If possible, test with another compatible, known‑good charger that meets the laptop’s specified wattage and voltage.

2. Confirm correct charging port

• Ensure the charger is connected to the laptop’s designated charging port (some laptops have multiple USB‑C ports but only some support charging).

3. Reduce power draw while testing

• Charge the PC while it is asleep or turned off to see if the issue persists. If charging is stable when the device is off, but unstable when in use, the charger may not be powerful enough for the load.

4. Check for cable/connector issues

• Inspect the charging cable and connector for any visible damage, kinks, or looseness.
• Make sure the connector is fully seated in the port and does not move easily.

5. If using USB‑C

• USB‑C can support up to 5V, 3A, 15W by default; higher power and faster charging require USB Power Delivery support on the PC, charger, and cable. If any of these do not support the required power level, charging can be slow or unstable.

6. Contact the device manufacturer

• If the original charger is used, the port is clean and undamaged, and the behavior continues, contact the laptop manufacturer to confirm the correct charger specification and to check for possible hardware issues with the battery or charging circuit.

If this is a Surface device specifically, follow the Surface‑specific power‑supply troubleshooting and charging‑requirements guidance in the references.
