Here are some you can try; [URL] [URL] It's possible that the Lenovo driver will work [URL] I don't have my 17 R1 ready to test one at the moment but hopefully one of these will work
Hello all, I recently acquired an Alienware 17 R1 i7-4700mq with an Nvidia GeForce GTX 765m gpu.. the laptop is in near new condition, and was even running windows 8 pro still, which is what it was shipped with. Bought from a seller who did storage unit auctions and was sold as-is with windows password locked, but have since found no defects at all after reinstalling windows.. I went to w10, and everything is perfect except for the error code 48 on the Realtek card reader driver.. I’ve looked over probably 50 or so posts online throughout the different pc makers with the same error, and all of their “solutions” did not resolve mine. Just says that error 48 pertains to a driver not allowed by w10 due to possibly of corruption. I’ve even tried the w8, and even w7 drivers as well (in compatibility mode) with no luck. It’s not too important that it actually does work, but I would like to find a solution for that one time I try and plug a memory card into it. thanks in advance
