<p>DieKatze88: /* Affected Models */</p> <hr /> <div>{{Stub}}<br /> Some recent ThinkPad models ship with Intel CPUs that implement the [http://en.wikipedia.org/wiki/Virtualization_Technology Intel VT extensions] for hardware-supported virtualization, but the capability is disabled by the BIOS. There is no known solution.

<p>DieKatze88: /* Z61t BIOS does not have VT */ +Add Lack of R60 support</p> <hr /> <div>== IBM/Lenovo support does not know about VT==<br /> Just talked to the german hotline, the guy didn't even know, that Intel CPUs does have VT (but he knew about AMD, which isn't used by IBM/Lenovo). So I got a new record in their support-list and they will call me back. --10:35, 14 December 2006 (CET)<br /> :Got a callback from Lenovo, they said I might have a modified Windows (because the laptop was bougth through the students-support-stuff) and as I said Linux, I got an &quot;unsupported&quot;. It looks for me like selling a Ferrari, but not telling where the gear-shift is... Found an interesting link on the net: http://forum.thinkpads.com/viewtopic.php?t=34454 - seems someone at Lenovo knows that VT is disabled... --[[User:Zhenech|Zhenech]] 13:12, 14 December 2006 (CET)<br /> <br /> Needless to say, it has nothing to do with the OS. It's a bit in a CPU register that's set by the BIOS before the OS even loads. --[[User:Thinker|Thinker]] 14:59, 15 December 2006 (CET)<br /> <br /> ::: Seems Lenovo has fixed the problem for the X60 Tablet, and I heard they plan a VT-capable Z61 BIOS for April, hope this won't be an aprils-fool ;) --[[User:Zhenech|Zhenech]] 10:01, 15 January 2007 (CET)<br /> <br /> == Class action? ==<br /> Clearly Lenovo is using false marketing. They sell Core Duo model with virtualisation but cripples them. So CPUs don't work as they should. I believe this is punishable by law. Anyone knows details what to do?<br /> Please note, that HP had similar problem but fixed it with BIOS update.<br /> <br /> ----<br /> <br /> If it not states &quot;on the box&quot;/manual/bill that it supports VT then Lenovo is not responsible for it.<br /> They can sell you a core 2 duo even without BIOS support for the 2nd Core, if the never mention it has 2 cores.<br /> --[[User:BDKMPSS|BDKMPSS]] May 28 2007<br /> ----<br /> <br /> It state that it has Core Duo processor. Datasheets on Intel site show VT as inherent feature of this CPU (except for lowest T2300e model).<br /> <br /> ----<br /> <br /> Thats right and they delivered what they told you. You can take the Thinkpad apart and use the CPU on another Motherboard with VT (if it is not soldered on the board). You got an VT capable CPU, but they never stated that the BIOS supports it. The Intel Datasheets are on the Side of the manufacturer (Lenovo in this case) they always state some sort of &quot;if individual BIOS supports it, maybe not available on all machines&quot;.<br /> I think this is a shame and I know why I'll never buy anything from Lenovo. I am just not comfortable with them.<br /> --[[User:BDKMPSS|BDKMPSS]] May 29 2007<br /> ----<br /> <br /> == Z61t BIOS does not have VT ==<br /> <br /> Shots made on 2007-03-11 [[User:Dmitri|Dmitri]]<br /> &lt;gallery&gt;<br /> Image:Z61t BIOS ver.jpg|Z61t BIOS 2.09 7FET91WW<br /> Image:Z61t BIOS ver closeup.jpg|Z61t BIOS 2.09 7FET91WW<br /> Image:Z61t BIOS menu.jpg|Z61t BIOS 2.09 7FET91WW Menu<br /> Image:Z61t CPU menu.jpg|Z61t BIOS 2.09 CPU menu - multicore enabling option only<br /> Image:Z61t CPU menu help.jpg|Z61t BIOS 2.09 CPU menu - seems like it's just enables second core of the CPU<br /> &lt;/gallery&gt;<br /> <br /> These shots are Identical (Except serial numbers) to the R60 Bios, the R60 does not support VT either. I'll update the page</div>
