T540p Intel HD Graphics Brighness and Sleep not working

Question

So, I just got my shiny new T540p with a 3K display and Win Pro 8 installed. I promptly upgraded to Win 8.1 Pro and now I have a problem with the Intel HD Graphics. Basically, the system will not turn the display on after a sleep and I can't adjust brightness. I tried downloading the drivers from the support page, but they reference a Intel(R) HD Graphics 5000 card, whereas my system says it has a Intel(R) HD Graphics 4600 installed. When I try to run the driver install anyway, I get a message saying that my system does not meet the minimum requirement for installation (??????). I tried manually installing the Intel(R) HD Graphics Family driver instead. This fixed sleep and brightness control, but then all things 3D was completely messed up (like buttons in Skype and Chrome). So I have nailed it down to a defective driver. Does anyone know where to get a driver that will fix this or some other method to get this sorted out?

 I got a brand-new Thinkpad T540p (64-bit Win7, 1920 x 1080 display) three days ago and it’s great except that each time it goes to Sleep or Hibernates there’s a roughly one-in-three chance that it will lock up and need a forced shut down. The brightness control works ok and this is Windows 7, not Windows 8. The drivers are all up-to-date according to Lenovo (I’ve done their recommended updates) but do you think this could be the same problem as described in this thread? Sometimes it freezes in the act of going to Sleep and other times it freezes on waking up. I’ve noticed three types of freeze: Type 1: the screen shows the default blue screensaver with a big ‘Think’ on it but won’t respond to any controls. (Pretty ironic this – it’s forcing me to think hard!). Type 2: the screen is all black but with backlighting seeping through. The brightness controls operate and if I click F8 I get the ‘Change Power Settings of Wireless Radios’ screen and all the buttons work, except when I click ‘Close’ they stop working and it freezes. They start working again if I press F8 again and the cycle repeats. Type 3: completely blank screen with no backlighting. F8 doesn’t do anything. In all three cases the keyboard lighting responds, the hard drive is spinning, the network connection is active, but the only way to a working desktop is a forced shutdown. I'm new to Lenovo so any help much appreciated. ------------------------Edit 15-12-2013 13:59 I tried updating the video drivers as described by Someotherguy earlier in this thread, but I'm still having the same issue with Sleep mode. The Nvidia driver is now 9.18.13.2768 (was 9.18.13.1269) but the Intel driver didn't change (it's 9.18.10.3272). So maybe mine is a different problem. Any clues anyone?
