Usb, wifi and sound problems with the Lenovo Ideapad 520-15IKB – Assistance Required!
Hello! I’ve noticed some unusual behavior with your Lenovo Ideapad 520-15IKB. After using it from Saudi Arabia to India, I experienced minor electrical leakage while charging, which wasn’t a major concern at first. After switching the HDD to an SSD and using it externally in an enclosure, the problem shifted to affecting my USB-A ports—especially when connecting the HDD. The mouse would lag or disconnect frequently, and even with the SSD, the touchpad stayed functional. Testing a phone and a 256GB SSD showed similar issues. Using a different USB port resolved most problems, but other ports still had issues. I also noticed audio noise in speakers connected via the 3.5mm jack, which worsened when the external HDD was plugged in. The USB-C port seemed to be working fine. It might help to check for loose connections, ensure proper grounding, and verify that your power supply is stable. Regarding the thermal paste, since it’s been nearly seven years, replacing it could improve performance, but you should also inspect the internal components for signs of wear. Let me know if you’d like more detailed steps!
