(Solved) T500 with device manager code 52 for audio and media (4in1 ricoh).

Prior to this problem, aforementioned drivers were installed for *first time* I get warning saying "Windows requires a digitally signed driver."...blah blah.

Got yellow exclamations for audio and ricoh 4in1 with code 52 for them, can not redo the drivers even I reloaded drivers from lenovo driver site for windows 7 pro 64bit. Also same problem for intel, amd drivers.

I never had seen that happen before and this is clean install.

Somehow I forgot that windows 7 clean install must had got corrupted while installing stuff. Had to format and reinstall again solved everything. Now enjoying installing stuff to get ready for my friend. He is sitting on R52 and a inspiron 1501 notebooks both XP.

Cheers, thinkpadcollection.
