You should only use 1 version of driver.
To avoid any problem, I strongly suggest you wipe clean all GT650M driver. Then install the driver from Lenovo.
Refer to my earlier post, until Nvidia announce their driver support SLI for GT650M (look for the link or Lenovo will definite annouce as well ), you should not update your driver with that from Nvidia.

Don't worry. It's no big deal

Read this: Official from Nvidia
http://www.nvidia.com/object/IO_13955.html

But, better is this. The above is not "clean enough" some times. This method use a software. The example is in Vista, but you get the message.

The best is this. This involve manually changing the regedit. DO NOT attempt unless you are absolutely sure what you are doing. The example is in Win7, but you get the message.

Try the 1st method first. If you don't encounter further issue after you re-install the driver from Lenovo, good

Sure Btw, that screenshot is after you install driver from Nvidia? or after you re-install driver from Lenovo? Did you restart, after installing any of the drivers? Sometime weird things happen after we restart laptop
Good luck

Ok, finger cross. If the beta driver from Nvidia work, good news

Yeah, most of the time the problem is not with Win8, but program we install that crash it

1. Not problem, just issues
a. Micro suttering. Some gamers don't care, for other it's deal breaker.
b. Not all games support SLI.

2. devour main thread in garage sales

2 things:

1. As always, make sure you prepare a recovery media before you play with partition.

2. Don't need to use any 3rd party partition software in Win8. Do you know Win8 has its own partition management tool?
Just type "Partition" and enter. You will see an Admin tool "Create and Format HDD partition". It's not flashy, but all the functionalities are there. You can resize all you want. Yet another proof that Win8 is better than Win7

Me bad I did not even realise that after using Win7 for so many years
I came across this feature as I was playing with the Storage Space features in Win8

Yes, I am aware that the OKR won't work if partition is changed.
OKR is basically a (tone down / rip off) of Thinkvantage suite long available in the Thinkpad series. When Lenovo bought Thinkpad from IBM, the wonderful blue botton in Thinkpad get migrated to the OKR in Ideapad (but with a lot of good features remove).
Ok, let me test if the Win8 restore and reset feature get mess up if I change partition in my Y580. If it work, then maybe it will be a better option than the broken OKR.

It's alright. I never care about the OKR anyway (after using T series a long time and see what a proper tool should be At least there is a fair trade off there)

Will work on this after kids going to bed tonight

And you may want to look at this thread if you are keen to get back the OKR.

Hope you get back your Y500 soon

Sure Lenovo can do a factory reset. Unfortunately you will lose all the personal data / mods you done so far
But you may not need the ODD. Win8 (or Win7), if you manage to get a copy later, could be installed from iso in a external HDD.
Or you might want to think about doing a recovery media to external HDD next time
Ok, I think I will follow this tonight:
http://www.extremetech.com/computing/13461...es-and-programs
It show the steps require to create a custom image for Win8 Refresh tools.
My 1st plan is as follow:
1. change the partition in Win8 of Y580. (btw, just to be clear, mine is a Win8Pro RM50 upgrade from Win7HB)
2. create a custom image for Win8 refresh.
3. Install a few apps.
4. run Win8 refresh and see how it go.
This is to see if Win8 refresh could be a viable alternative to OKR if we decide to resize partition. I don't aim to recover OKR

Yup, the key come with your Y500 can only legitly activate a Win8 (non-pro).

Indicative price?
Ultrabay GPU standard or optional?
Is Lenovo Malaysia replacing Y480 with Y400?

This post has been edited by nexus2238: Dec 7 2012, 01:10 PM

RM100 more than Y480. If specs stay the same, still worth it looking at the improved design

Aiyo, GX60 is A10 + HD 7970M. Totally different class How much, RM6-7k?

Don't worry lah. AMD GPU still very competitive vis-a-vis Nvidia (just wish they could just put more effort into driver support, the price premium that Nvidia charge on the high end is really ridiculous). Only the CPU business totally whacked by Intel.

Good deal. Not all games faced CPU bottleneck. And your GPU blow Y500 away.

Care to share the full spec at this thread so that TJ could update?

Check here to see what game support SLI:

^I remember looking through the full tear down guide of Y580, the layout of the wifi attenna is not typical (some sort of new layout scheme).
Till this day, I still strongly suspect this new layout may have lead to wifi signal interference (hence the weak wifi is not solely due to adapter) in Y580 (and may have pass the curse to Y500 )

But I don't bother to test my theory since my Y580 is also plug into LAN at home

^very subtle, sifu
