lenovo z510 not detecting card reader after upgrade to windows 10

I have tried updating and downgrading and have found nothing that will get it to work. The laptop came with Windows 8.1 and the reader worked fine. It was after the Windows 10 upgrade that it stopped working. As far as I can tell from Lenovo it is a Realtek
card reader. There is no way to confirm as it does not show in device manager.

 

Built in SD Card reader for Sony Laptop not working after windows 10 update

I have a Sony VAIO VPCF127FX laptop in which the built in SD card reader doesn't work after upgrading to windows 10. I have found that Lenovo has an updated driver for the same model driver. The SD card driver is Ricoh PCIe SD Bus Host Adapter driver.
Would the update work even though I have a sony not a lenovo?

 

Just checked my Lenovo laptops and they have Ricoh SD card readers installed. Have you tried visiting the support page for your Lenovo make/model to see if they have a usable driver? Have you tried running the Lenovo Companion or their System Update utility to see if they can detect any potential issues? Might be worth checking into, if you've not already done so.

did both first thing , i'm on their latest set of drivers, my card reader is realtek , windows generic driver and lenovo's latest one both act the same , its as if windows is capping write speed .
