September 24, 2025Sep 24 Hi guys, I just want to share result of 3 day investigation. So I am running my Unraid on thinkpad W530 mounted on wall using 19 inch rack tray. However laptop is mounted vertically so I have elastic gum that i snap in to hold it by the wall. Recently I was having problem with express card usb not appearing, sometimes laptop didn't reboot but was stuck on lenovo logo screen. I had to open lid, kill it with power switch and boot again and so on. In dmesg I was seeing constantly ACPI BIOS Error...So what was the reason? In some unknown way when lid was closed and elastic gum was holding laptop against wall (not very strong, really light pressure) it was enough to press some buttons on touchpad or on the keyboard I suppose. This pressure was causing mysterious acpi error and was preventing from proper reboot and making express card usb 3.0 not visible.SOLUTION:I have glued two pieces of sponge on the top, where lid closes, so it is closed but not completely. Problem is gone completely!!! :D Edited September 24, 2025Sep 24 by Kacper marking it solved
