lenovo intel graphics driver windows 10 w540

I know for these things, the Intel HD graphics must be using the modded drivers by AMD to work, but even with that it is still no good. Tried disabling the switchable graphics and use integrated only, the laptop would boot up just fine decently fast, but even though the Intel HD graphics driver is properly installed, the laptop acts like as if it is not, and it is laggy and goes up to XGA only.

I don't exactly need the discrete graphics to work, but at least I want the laptop to take a reasonable amount of time to start up so the owner would actually like using the laptop. I tried to use a slightly newer driver by Sony, but can't extract them without a Sony Vaio laptop and I anticipate those to not work either. I tried the Windows 7 and 8 drivers provided by Lenovo, neither worked at all. I updated the BIOS to the latest version from 2013 (and also learnt the hard way you should NEVER flash the BIOS in Windows 10 because I got a bluescreen right when the software starts flashing! Fortunately it's also right before it erases anything so I didn't end up with a bricked machine! ), but it didn't help. Apparently it is not, but it takes over a minute sitting there on a blank screen every time the laptop starts up before responding again and it gets very annoying and eliminates any speed benefits of the SSD. With the drivers microsoft automatically downloaded from Windows update, it would work when it installs it but then when I reboot it goes to a blank screen and I thought it's frozen there. Mine is the version that comes with AMD switchable graphics (Radeon HD 6630M) with the built in Intel HD 3000 graphics, and I am having a royal pain trying to get that to work in Windows 10.

However the hurtle comes when I try to put Windows 10 on it. So as usual I upgraded the poor 2GB of RAM to 8GB and then added an SSD on that thing. I am trying to save a ThinkPad E420 that the owner deemed it as junk and old and wanted to throw it away.
