Really???

If its true, then that's a bargain......i think..... lol

Seems like a hardware problem. I would suggest that you sent to SC to check since its a new computer with warranty.

Urm, anyone got Lenovo's Customer Support E-mail? I need to ask them some questions :3

What, Qualcomm?


I have a similar issue with wireless card, more like OS problem since I didn't had it with Windows 8.

It does look to me the driver is the one having problem... if it's hardware, it's high likely you won't get the 2nd graphic to turn on at all... what's your driver version?

I tried 306.30 and also the latest driver from nvidia website. Both has the similar problem. When it is started from shut down state, 2 x graphic card detected. but when it is restarting, only 1 graphic card left, 2nd and 3rd restart also same. Also, I tried boot it from shut down state using only battery, 2 x graphic card detected.

And I am using Windows 7 Pro, installed on Kingston MSATA. Another harddrive for data storage.

Is it confirmed hardware problem?

Update:
I just found this: https://forums.geforce.com/default/topic/52...d-dual-monitor/ and seems like a lot people is having this same problem, and from the forum, they are also using Windows 7 64 bit, same as mine. So, anyone here running Windows 7 on Y500 GT650M SLI having same problem? (restart -> 1x GT650M, shutdown&start -> 2x GT650M)

All I can think of is to do clean installation of driver (I think there's an option for that while installing, or better to remove all remnants of old driver before installing new one).

ew-ropDid clean installation (check that option on custom installation), same result. Anyone here using Y500 SLI running Windows 7? I am thinking that maybe the problem is with the incompatibility of Y500 to Windows 7 because its default os is Windows 8.

call SC to see what they say la.

how to fix?

Yeah but he's asking for Y480/Y580

I wouldn't advise you to get that fan ultrabay. If you open the back of your computer before you will notice that there is no point for a fan in the bay cause its almost closed and not connected to any heat pipes of the computer.

Don't get fan ultrabay.
People who got that already stated that actually nothing really different.
The temperature may only go down 1 or 2 degree.
