Some frustrated Lenovo users have been posting lately on support forums that they are having troubles with theSD cardreaders on their tablets after making the upgrade to Windows 8.1Lenovo users seem to be among the most affected users by Windows 8.1, as they have reported issues withbattery drain, sometouchpad problemsandslow performance issueswith the Yoga 13 Windows 8 hybrid device. Now, a number of users is reporting that they are having issues with the functionality of theirSD cardreader after upgrading to Windows 8.1.

Here’s how one Lenovo users is describing his problem:

Upgraded to Windows 8.1 and the Realtek SD drivers in the download are for the P400 Windows 8.0 does not appear to be installing…  Can’t find it in Device Manager, not being recognized when inserted.   Nothing wrong with the hardware because it works in a VM under windows 7 with no problem.  Anyone else having this problem?

Another has reported a similar issue back when Windows 8.1 wasn’t even released, and he had actually updated to Windows 8 from Windows 7. Here’s what he said at the time:

Got an issue with my card reader, bit weird, upgraded to Windows 8 from Windows 7, all worked fine before. Any how, I’ve downloaded latest drivers for myRealtekSD cardfor Win8. When I insert aSD card, Win8 recognises it ok and opens the folder on the card. I then “safely remove hardware” , ejecting the card. This is where the problem is. I then re-insert theSD cardback in and “No response” from Win8. I go into Device Manager and everything is ok. I have to restart the laptop for it to clear. Then its fine for one time again.

I un-installed theRealtekdrivers and let the Microsoft generic drivers kick in. Same again, but when i go into Device manager, there’s an exclamation mark on the card reader saying. “Windows cannot use this hardware device because it has been prepared for “safe removal”, but it has not been removed from the computer. (Code 47). My laptop is an Acer 5735z running windows 8 64bit. All was working when running windows 7 64bit

So, as we can see,Realtekseems to be the culprit, and I have researched more on this subject and, indeed, found more Windows 8.1 laptops having RealtekSD carddrivers with problems. We’ll investigate more and get back to those affected when we will find more about this another annoying Windows 8.1 problem.
