You have igpu / HD3000 graphics. Look at it this way dgpu is just extra, igpu is primary card. You have to hot plug it as i mentioned in steps 2,3

If he has i7 proc he should have hd3000 graphics, the point of switcable graphics is igpu+amd dgpu.

1.If you can disable in bios dgpu then restart - if not you have to buy diyegpu setup 2.press F8 to get to advanced startup options 3.power up egpu and connect expresscard 4.resume win,you should see your card in device manager 5.install drivers (try to find some unified drivers for mobility/desktop support,it will be better if you have bought nvidia card / or try with normal catalyst driver / make backup of you laptop before so you can easily restore back),after installation of driver you will be prompted to restart (after restart quickly pull out expresscard) 6.power off egpu then power on,repeat steps 2,3,4

Yes ofc, when the manufacturer says that you need xxxW they mean with total system.You will be running only the card. Your card has 250w power cosumption so you can use lower psu.Just check that psu has sufficent amperage on rails.

Do you have PE4L, if you do then check in bios that your expresscard speed is set to 2.0. Then, did you halt Win with F8 then connected expresscard and booted to win? Also check link speed when gaming or other intensive GPU activity.

Try with Win 7, and also maybe you are cutting it too close for power req,as gtx770 uses 200W i think,if you have regular atx psu to try.

You can buy on ebay/amazon original apple cable for 20-25$ and belkin at around 45$.

Sadly no,but at this moment the best cost effective solution is thunderbolt Sonnet Echo express card adapter used with pe4l. It should still give you very decent performance.

Maybe you can try halting win with F8,than plug thunderbolt, power up xbox adapter,and resume win.

Upon boot you press F10 not esc. Than in system subsection you select 2nd row where your expresscard speed,sata,integrated peripherals are. Down on the bottom you have tick box under switchable graphics, and just untick the box and save bios. I can't remember by hard i'am at work now. I will update this post when i now exactly where it is located. After saving bios you halt win (F8) plug pe4l resume win.I suppose you have valid nvidia driver installed before hand.When you get in win you will probably still have win on you laptop screen.You have to go to display properties and select screen number "2" external monitor if you have one. Good luck, it should work,except if something is wrong with PE4l adapter.

I have HP 4530s it's basically the same except screen size. Express card slot is very fiddly of probook series, you have to insert it very swiftly or sometimes it can't be recognized. So if you have dedicated graphics hd radeon you have to disable it in bios than halt windows with pressing F8 and than plug pe4l and resume win. If you have only intel than only halt win with F8, plug pe4l than resume win it should work.

I'am afraid it's not possible to have egpu on usb 3.0. I think this is more for embedded system,problems with drivers,bus architecture difference between pcie and USB3.0.

Yes it's x1 2.0 , but it's weird i'am not getting 19k score. I think it's because of the cpu.

Ok i hotplugged egpu,and here is my 06 score NVIDIA GeForce GTX 660 video card benchmark result - Intel Core i5-2410M Processor,Hewlett-Packard 167C score: 16411 3DMarks . It looks a little low, as far i can tell i should get 19k. That score is on external monitor. Is that ok?

Ok will try, thanks.
