I've got an Alienware 14 (2013) here that has a GT 750M 1GB with switchable graphics to change between Intel/nVidia. It does not show up in BIOS anymore. BIOS lists "Intel Haswell" under "Integrated Graphics", and under "Dedicated Graphics 1" it shows "[Not Detected]". There is very clearly a GPU on the motherboard as you can see it with just the bottom off. Normally I would just reseat the video card, but this one is built into the system board. The laptop functions perfectly with the exception of the missing GPU. Any thoughts on how to get it to detect again? Edit: It already has the latest BIOS (A09) and I've tried reflashing it as that's what Dell recommends. It didn't help. Edit 2: Flashed the BIOS again and booted it. Windows started installing Bluetooth (which I didn't realize wasn't working) and it got a new graphics device in device manager (still not showing in BIOS). Hit the graphics switch key, rebooted, and installed the nVidia driver and rebooted again. So now the driver is installed, but I can't get it to actually use it yet. Checking BIOS again still reports it as missing. I guess it's time for a third flash.
