I have several Thinkpad model T61 laptops running Windows 7 x64 and I came across an unusual problem. When installing windows and using lenovo system update, I'm left with three "base system devices" in device manager. These are for the Ricoh 4 in 1 card reader. The solution is to get the 64bit vista drivers
, extract them but instead of running the setup.exe, go to device manager and use the "update driver
" then browse to the folder, however when I do this, I get an "unsigned driver error"
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
I've deleted and reinstalled the drivers over a dozen times, every way imaginable, but nothing works.
This is a new windows installation, and just to make sure the drivers work, I installed the same windows version on two more thinkpads, same model and the drivers worked.
The only thing I did have trouble with is I inadvertently unplugged my cmos battery when doing some upgrades and operated the computer for about a day when it was set on the wrong date. That's long been corrected, long before I installed these drivers, but it's the only thing I can think of that is out of the ordinary.
I'm tempted to just reformat, but I just did that (again), after a linux installation caused windows not to boot, and I spent several hours installing software, so I'd rather not start all over yet again.
