Usually folk load the recovery because of a failure such as the mic.
And let's be clear here. XP and even today's Windows have NEVER detected a microphone. That has never happened. I've seen helper apps show that the mic was plugged in but this is just the mic switch detection and nothing more. No mic detected.
So we have 2 issues. ONE, why did they reload the OS and TWO, mic detection never was a feature.
My levono ThinkCentre M55, will not recognise microphones, after I did a rescue and recovery to wipe back to factory state. My OS is XP Service Pack 3.
I have Previously installed all compatible Audio Drivers, from Levono.
