    I think they were the old ones people returned. I bought one of the $639 units and it was manufactured back in Oct 2012 so it's almost 5 months old.

    It seems OK physically except one corner of the keyboard is loose.

    One more here who did a clean install. I backed up all the original partitions as compressed images using dd in a linux live CD. Then I wiped the disk and ran the standard Windows 8 installer. I don't have the yoga in front of me, but I believe by default Windows 8 creates a main partition, a recovery partition and maybe a suspend/resume partition.

    If I remember correctly, the only partitions you "lose" by wiping are a Lenovo-specific restore image and a small one with the driver files in it. I didn't need the restore image since Windows 8 lets you create a clean one of your own, and I didn't need the other because I copied out all those driver files for storage elsewhere. But since I made backups I should be covered either way.

    If you're doing a fresh install I recommend the Windows 8 guide over at Ars Technica. It has some good info on creating your own "Refresh and Reset" image. I was able to do it as a file within the main Windows partition rather than a separate recovery partition. I think that gives me more flexibility and easier backup.

    Thanks for remembering, one of those questions was from me. Since I asked, I returned the Yoga13 for which I had paid full price due to many annoying bugs and just bought a refurb Yoga13 from the outlet for much less money. So far, the refub is doing ok except one corner of the keyboard is loose. The quirks I disliked at full price are much less annoying for $636.

    I like your idea of going with USB-->VGA adapter since that will last you years and be usable with many different machines if needed. I almost followed your lead and bought the same one...then I saw the official Lenovo HDMI-->VGA adapter was only $14.99 on Amazon so I thought I'd give that one a try.

    Edit: I tried the Lenovo HDMI-->VGA adapter this week with a projector. It worked great of giving presentations (no audio, just screen mirroring).

    Link will go to an error page of Out of Stock:
    http://outlet.lenovo.com/SEUILibrar...E4F2C44807BDD88B14FA6B5576&item-eol=1&redir=y

    They seem to get them back in stock almost daily.

    Try in the morning, or sometimes people seem to indicate stock gets in at NOON EASTERN.


    My friend scored one last Friday shortly after 1pm ET I think.

    I posted this over on the Lenovo-forum but would like to ask here as well, does this happen to you?

    I've noticed a big difference in multimedia applications performance depending on whether the Yoga 13 is in laptop-mode or tablet-mode! I don't remember marketing mentioning anything about perforance being affected by in what mode the computer is used...

    Can anyone else please confirm this happens (measured with fraps)?

    Examples:
    • Civilization V 3D-graphics laptop-mode: FPS ~25-30
    • Civilization V 3D-graphics tablet-mode: FPS ~8-15 (unplayable)
    • Civilization V 2D-graphics laptop-mode: FPS ~60
    • Civilization V 2D-graphics tablet-mode: FPS ~30
    • 1080p Youtube-video in Chrome in laptop-mode: FPS ~30
    • 1080p Youtube-video in Chrome in tablet-mode: FPS ~2-10 (stuttering a lot)

    Tabet Mode is slow:
    -Lenovo under-clocks the processor to 800Mhz in Tablet Mode to keep the heat low. If you don't want this, do one of the following:
    -Uninstall Intel Thermal Framework in Remove Programs. Removing this will prevent it from doing that. I haven't done this, so I don't know if it's recommended. I did do the following:
    -Alternatively, Hold POWER Down for 10 seconds to COMPLETELY turn off the computer. Start it up and hit F2 to Enter BIOS, switch to 2nd page, disable DPTF, save and exit. I haven't done any benchmarking to verify this works.

    Thanks, disabling it in bios did the trick. Now I wonder why it comes enabled, there must be some reason to it.

    Cheap(er) Yogas were in the Outlet again last night, picked one up for the wife for $629, too good to pass up.

    I can confirm that the MSDN ISO works fine to reinstall WIndows by picking up your bought-and-paid-for W8 BIOS key. I diid attempt the "N" Euro version (without WMP) and that didn't work, but the normal Win 8 did however. I played it very conservative though, because I want a surefire way to restore to factory conditions. So, first I made a whole disk backup with Macrium using theiir UEFI-compliant WinPE 4 boot drive. No fiddling with Legacy boots. Then, in Windows I created a recovery drive with the option "copy contents of recovery drive" to the recovery drive. I now have a backup of the recovery partition. And, while probably unnecessary, I also created a system image, which I was happy to see creates images of both the WinRE and EFI partitions as well.

    Then, installed W8 by using the install's format drive function for the C system drive *alone*. That way, I maintain the exact partition structure for an easy, worry-free OEM re-install if need be. The new W8 partition simply re-uses the existing WinRE, EFI boot, and MSR reserve partitions. This is one really nice SSD W8 install guide here -----> Sean's Windows 8 Install & Optimization Guide for SSDs & HDDs.

    With all drivers available online and the ability to get Lenovo Companion (Lenovo Transition app available within) and Settings apps in the Store, you can get all original functionality back without all the freeware bloat. The only thing I have not installed is the enormous Intel MEI driver/application. It seems this is entirely unnecessary (for remote access), and there are no driver-less devices left on my system. I have also disabled all the "tray" user configurable front-end software in the startup tab of the Task Manager with no undesired consequences.

    I've applied the Lenovo "fan fix" which overwrites the BIOS's EC section to raise temp thresholds for fan speed. I've also used this to get rid of the annoying WMI Provider Host CPU usage bug, where it continues to use around 1.5 - 4% in the background and contributes to wasted heat while idle.

    cmd /c start /min "" "C:\Users\root\Documents\Lenovo Yoga\WMI Fix\wmi_fix.bat"

    "wmi_bix.bat" contents:
    Code:
    timeout 5
    net stop Winmgmt /y
    net start Winmgmt
    net start iphlpsvc
    net start wscsvc
    exit
    
    Now run "task scheduler" (run as administrator) and create a task named WMI Fix. Make sure that:
    1) you change user ('When running the task, use the following user account') to SYSTEM (click on 'Change User or Group' and just type it in as SYSTEM),
    2) select 'Run whether user is logged in or not'
    3) check 'Run with highest privileges.'
    4) In the Triggers tab, create new trigger as 'at startup'
    5) Click 'Delay task for: '1 minute' (this may not be necessary)
    6) In the Actions tab, click new action, Start a Program, and browse to your bat.
    7) In the Conditions tab unclick 'start the task only if the computer is on AC power'

    That's it! Check to make sure it worked by rebooting your machine. The 'WMI Provider Host' should now consume 0% CPU.

    Happy to report, after a backorder, I received the adapter and it works perfectly with my Power adapter from my trusty T400 65W / 20V adapter. Same polarity and output amperage (3.25A).
