I don't think this is about the hardware driver detection of the lid closing. Lid events are a first-class thing in ACPI and I've never seen a laptop that didn't have one, or any real evidence that one didn't do the thing.

Much more likely is that the OS was prevented from going to sleep by some badly behaved process, or got woken up by another thing like allowing USB to wake it from sleep, where even touching the mouse can wake it - with some laptop equivalent like a ghost touchpad touch or whatever.
