That's important info. ADATA SP900 Premier Pro 2242 ssd's have a firmware issue. It won't work with Windows 8.1 and AHCI mode in BIOS. You can however use it with Windows 7. I don't remember all the details but a google search for "adata ssd y510p" will help. Bottom line, if you want to use it you'll have to install Windows 7. PS. Nice work with soldering!

Specify which SSD and windows version. Any BIOS setting you might have changed? A bad soldering perhaps?

I didn't know about the IGPU problem. But there's still a chance to get it working. Atleast you should be able to install OS X. QE/CI is a diff matter of course. In Y510p, some progress has been made with using using the system in SLI mode. Of course, the SLI is not supported in OS X and no QE/CI yet, but you may have a look here. I don't have much idea about SLI, since i don't have one. If you need any help, create a thread in there and I and others will take a look. Hope you succeed.

Can't you choose "UMA" from BIOS instead of "Discrete"? FYI You can boot into OS X with or without Ultrabay. The actual problem comes with enabling Graphics Acceleration. Switchable graphics WILL NOT work with OS X. One more thing, using DSDT from another computer is a very bad idea even if its the same model/pc. A small change in ACPI can result in unexplained behaviors. I would advice anyone not to download or use DSDT from internet. PS. Its pretty easy to extract your ACPI tables (DSDT, SSDT etc) from any OS. RW-everything in windows for example.

Oh. That would explain PEG setting reset. I'll not disable IGPU but i was thinking of making the discrete card as primary graphics but i've seen in other forums the danger of this (bricking). I think i would probably stay away from this Enabling IGPU while in SLI would be great but i have no idea on this.

If you're saying that "one cannot enable PEG unless he's using SLI" then you're dead wrong. PEGP stands for discrete graphics card. It doesn't matter if laptop's SLI enabled or not. That i'm afraid of.

No. I'm trying to disable IGPU and/or enable "PEG" from "SG" under "primary graphics" as i said in above post.

Anybody having problem with "video settings"? Everytime i disable "IGPU" and/or enable "PEG" from "SG" the settings reset to default after exiting from BIOS. @svl7 I'm sure this is a bug. Another user reported the same. Any help?

Don't know. Cant flash it. I have another wifi card installed after flashing mod BIOS.

A new BIOS update v3.08 is released. Laptops and netbooks :: IdeaPad Y Series laptops :: IdeaPad Y510p Notebook - Lenovo Support (US) I was wondering when would the mod be available. Thanks!

It's not that difficult to install OS X in y500. In my y510p it's running flawless without any probs.

I think you are talking about DVMT pre-alloc memory. You don't have to change it. Intel HD4000 is supported natively by OS X Yosemite. Search in google for "Fix Intel HD mobile in Yosemite"

Petitions doesnt matter most of the times. They rarely do anything. But still signing anyway.

If by flashing the actual card you mean installing another wifi card supported by BIOS whitelist then yes, it is more easy considering you already have bought a wifi chip supported by your BIOS. But the list of cards supported by BIOS is very small. If you are not under warranty you should remove the BIOS whitelist by flashing modded BIOS. After that you can use any half size mini pcie wifi card.

Have you tried it? I mostly use throttlestop and i am going to try and unlock my BIOS as soon as i complete my 5 post rule (cannot download the attachment). And as my laptop is not under warranty anymore i am afraid of it bricking.

Hey guys, i heard on every forum that Y510p's don't come with M2 NGFF SSD slot. I bought my new Y510p (Model: 59390016) yesterday and guess what, it DOES have a connector slot for SSD. I guess new models are coming with connectors. Check out the attachment for pics. Thanks. Unable to attach images.

Hey guys, i saw on every forum that Y510p does not come with a SSD slot. But i just bought y510p today and i found that it has a SSD connector slot. Maybe new Y510p's are coming with a SSD slot. Check the attachments for pics. Thanks!
