Real good thread buddy, good one (had no idea about NGFF!). With switchable graphics enabled, do you mean that it supports Optimus? Y400 should probably use same LVDS screen cable as Y410p, which means 900p screens might soon be available. Can you confirm that the Y400 chassis is same as Y410p, or at least around the screen?

Ended up finding a Lenovo W5xx series 170w adapter for a mere 30USD and decided to simply resolder the power cable on the brick board. Works fine and dandy, cheers guys!

Hi all, I was wondering what PSUs people are running on their SLI systems? Is the official 170W really enough on full load and overclocked? Also, does anybody know what the connector type is called? I was thinking of getting a ~200W brick and using an adaptor to make it fit the Lenovo. Cheerio

I agree with wed_wabbit; why are you choosing to install Win8 in Legacy? You might as well go for Secure Boot and UEFI. UEFI vs Legacy has nothing to do with SSD support; it's purely to do with the boot process. There are several guides on how to optimise Win performance using SSD, and to keep read/write to minimum. They involve fun things like disabling prefetch, superfetch, and a few others. Google is your friend.

The only thing that springs to mind is spin-up, which is only relevant if you're booting from a HDD. I had this problem bonkers ago (around Pentium 4 "era") and it was related to the HDD needing more juice than supplied on start up, so BIOS didn't detect a bootable drive until second boot when HDD had spin up properly. On unlocked BIOS, there's an IDE menu with your IDE/SATA devices. Furthest down on that page you'll see the device list and number. Try changing your HDD's Staggered Spin Up state, and see if that does any difference. Otherwise, I don't know.

The Lenovo energy management does weird things on seemingly a "deeper" level than the normal Windows/Linux management, I can definitely confirm that. After I uninstalled mine it stuck at 135MHz and 405MHz (P8 and P5 states), and I thought there was some weird thermal throttling going on. I installed the program again and set to High Performance, then uninstalled, and it now works as it should (all states available).

An unlocked BIOS should be able to turn off integrated graphics (the y400/500 has a menu for this, although Intel gfx is disabled by hardware). There should be a "preferred" setting in the Optimus menu, maybe that will enforce your 750m?

Hi again and thanks for your reply. I've replaced the 2.5" 1TB Win8 UEFI with 2.5" SSD with Win7 non-UEFI; that's why I think it has little to do with legacy settings. Again, if there was an installation problem Ubuntu wouldn't boot at all; now it boots only when the 2.5" isn't inserted. - - - Updated - - - Hiya pektus, and thanks for the reply; good to see that someone is changing at least something in their notebook Hmm, so you're running UEFI then? And you've got a 2.5" attached? I wonder if the problem is related to the way the BIOS treats Legacy booting :/ I'm non-UEFI on both Ubuntu and Windows; that's the only difference I can spot between our setups (and win8 of course...) Unfortunately, I've already tried installing without the 2.5" attached which results in the same problem. BIOS (in Legacy) seems incredibly persistent on booting from the 2.5" when there is one. I guess I might just have to reinstall Win7 in UEFI (URGH...) and then try Ubuntu in UEFI too... Thanks for the tip!

can you please confirm that booting to your mSATA works when there is another drive (e.g. storage or separate OS) attached to the 2.5" normal hard disk bay? I can't boot to mSATA with a drive connected to 2.5", that's why I am asking.

Surely someone must have a fan for photos? This is an interesting area for putting fan mods in...

Hi all, I'm having big troubles booting from the mSATA when a hard drive is inserted in the 2.5" hard drive bay. I'm attempting to boot Ubuntu off the mSATA and GRUB (bootloader) won't even load; it just reaches a black screen and enters a high-power state. If I unplug the 2.5" drive and leave it out OR insert it in the CD/DVD with a caddy, it boots mSATA fine. Can anyone please confirm that booting mSATA works with 2.5" inserted? Could this possibly be a manufacturing error? BIOS?
