Some months ago I flashed svl7 8.01 modded BIOS to my Y580.

It works really great, but some time ago my GTX 660m disappeared.

I tried everything related to drivers and BIOS settings.

Do you have any idea of what can cause it?

How to solve it??

It happens to my friend. it this case it was problem with "user" He had issue because in fact BIOS on laptop was 8.0 but he tried 8.01 and during conversion locked-unlocked bios as it written in the instruction some information was lost. it was fixed by installing original 8.01, then unlocked 8.01

One more thing, most probably to install original file you need to use flash utility provided by the vendor.

Hope it will help

This apply to me??

This applies to my case? Of missing GTX?

Anyone experienced issues with the GTX 660m disapearing after modded BIOS?

Mine disapeared, and I tryed everything related with BIOS and Drivers.

Have any other clue but hardware, now I'm running only with HD4000.

Anything that may help me?

You will not get everything to work, like dual VGA, but everything else is possible...

maybe you have to switch your wifi card or use a USB dongle...

Go to tonyosx forum and read read and read

I have same issue with my y500. Somebody from official lenovo forum found that lenovo made a mistake with isolating the touchpad and issue occurs with ELAN touchpads.

I removed the cooper piece for isolation and putted some isolating tape. No results.

Also I tryed sanding the plastic around, again, no results.

I guess the problem is in the flat cable or connectors. beacause now it works sometimes, and after a couple of minutes it stops. Suggestions?

I putted a folded paper under my touchpad to avoid the connector of disattaching, it solved the problem but the clicking is impossible.

Only tapping available.

I will disassembly everything and try to fix the original fixing.

Aparently all lenovo y500 series have this issues

I have y580 too, and my touchpad wasn't working well.

I installed the most recent synaptics driver, disabled special functions like pinch to zoom, chiral and twist rotate, and set to minimum palm checker.

I also installed , and all worked perfectly,incredibly better than stock!

Gonna Try this solution!! Thanks

anyone with hunger games?

Hey guys,

I have my y580 that I bought refurbished from lenovo in US.

Thing is I live in Brazil, and they do not have support for this model over here, so RMA is not available

2 months from the day I bought it, the touchpad started to present some flickering and random stoppings,

I already did some research online and found out it is a common issue. recently it stopped at all.

I'm not sure what is failing, the touchpad, flat cable or some connector, any thoughts of where to look first?

a million ways to die in west!! Kind of a nice movie!!
