The laptop USB ports function in BIOS but not in Windows? ? ?
Hi, the laptop stopped working with its keyboard and trackpad one day. I tried using my PC keyboard, which worked fine. In BIOS, USB ports functioned properly, and even the regular keyboard did. But when installing Windows via USB flash drive, the keyboard and trackpad stopped working. I had to remove the HDD, install it on the main PC, and then reinstall Windows. The same issue occurred. It was either Windows 7 or 10, but nothing changed. Now, when peripherals are connected, they light up but shut down after entering Windows on the laptop. Even in the same session, they don’t turn on properly—they just stop working completely. I’ve disassembled the laptop many times, everything seems to fit correctly and there are no missing parts. The BIOS doesn’t have a USB Legacy option, and there are no USB settings available. It’s an old Dell Inspiron, about ten years old, with a basic BIOS. The laptop is always plugged into the charger, which suggests a typical battery problem.
It's a Dell Inspiron M5110. I tried Windows 7 and Windows 10 and Windows 10 always works with plug-and-play with my peripherals as i always used them and they worked perfect.
