Laptop Turns Off When Plugged In But Not Always

[toptom]

Hello. Maybe somebody can help me with this issue with my old Lenovo Y480, it turns off without proper shutdown.

Other inputs:
1. Still happens if I remove the battery.
2. Does not happen when in battery mode
3. I notice that the laptop getting hotter when plugged in, before it shuts.
4. Sometimes it can last 8 hours while plugged in but the issue usually happens for less hours, even minutes.

Thank You!

Try a different charger, check/replace the power jack.
