Reipete 10 Posted March 16, 2014 So here's the situation guys....I bought a GT750M5 Ultrabay from a reliable dealer that I know, and plugged it in. However, apparently the system fails to detect it, the second card cannot be shown at device manager, I tried to update vBios through the lenovo official website and crap...it saids something like EEPROM not found, MINDBLOWN.So, i gave my laptop to this friend of mine to fix it, he updated the bios to 2.07 and nothing is fixed except this time, the system with the SLI cannot be started, after i pushed power button, black screen appears (not even the "lenovo" word) but, without the SLI the system works fine and normal startups can be made. MINDBLOWN again. This situation is really irritating me as I tried every method and nothing is working... Really appreciate any help from you guys!!

Varroa 15 Posted March 18, 2014 Check my thread, basically the ultrabay 750m5 card is incompatible with the Y510p despite what the website says. I have a 40 page long forum post in the Lenovo forums and a huge amount of posts about it over at Notebook review forums. Sorry but there is nothing you can do to make it work.

Fezzik 10 Posted April 15, 2014 Well this sucks. This is the reason i bought the notebook. I may have to call lenovo out on this one. Quote Share this post Link to post Share on other sites
Varroa 15 Posted April 15, 2014 Yep, that is the only option now. The more people that call and complain, the more chance this will get fixed. Quote Share this post Link to post Share on other sites
fejerm 21 Posted April 16, 2014 Have you bought the 170 W AC adapter too or are you trying to use the Ultrabay VGA with the default 120 W AC adapter ? Quote Share this post Link to post Share on other sites
Diasetsu 10 Posted April 16, 2014 Even with an 120w it would at least register if there wasn't a problem with the card itself, you just wouldn't be able to use it long before something fried or powered down. I know while I was waiting for my 170w to come in I was able to verify my ultrabay card worked using my 120 adapter. Quote Share this post Link to post Share on other sites
freedomlh19 10 Posted April 18, 2014 How much did you pay for your GT750M5? I don't know if this will work, but Lenovo offers a GT755m5 for $99 when you buy a Y510P. So if you didn't buy yours too long ago, try calling sales and asking if they'll still give you one for the discounted price. Quote Share this post Link to post Share on other sites
