Razer Blade 15 advanced 2020

There’re no driver for sd card slot that you should manually install, aren’t there. It’s basically io port that windows will detect and install the proper driver for that through like windows installation or update. For core setting it’s drivers crash between dgpu and gpu inside enclosure (egpu), pretty known issue in early setting stage, your laptop confused recognize the proper gpu once it’s unplugged thinking you disable dGPU manually and loss the connection that make you need to install new driver. It can be solved be restarting the system, clean install and doing double driver installation (before and after egpu connection), or doing ddu nvidia uninstaller manually. Once the system fully recognized both dgpu and eGPU you should be okay with plugged in and out. However sometimes windows might be bugging and similar thing happens. To avoid that you should manually disable dgpu before connecting and before unplug disable Egpu, that hassle procedure can be avoid by using razer gpu switcher that can be downloaded from Razer website, it’s actually made for blade 14 2016/17 but I found still working fine on my 2018 blade 15 and stealth 2019 with dgpu. Hope that help.
