I have a HP Touchsmart tm2, and when I attempt to install Windows 8 x64 it eventuall errors out with "ACPI Support - Your PC does not support ACPI. Contact your PC manufacturer or retailer to see if an upgrade is available".
Are there any more clues what could trigger this in a log file somewhere? All the ACPI drivers appear to be healthy in device manager, and drivers and bios are up to date with what HP offers on their site.
Check your bios and see if there is an update for it.
I've installed the latest updates.
I have the same problem on my TM2. If I run setup by booting from the USB then it hangs for 10 minutes and then prompts me to install drivers.
Has to be a Pass/Fail issue APCI 2.0 Support has been around since XP sp3 I remember another install issue Back in Vista era involving ACPI 2.0 all my TM2 shows is a "Microsoft ACPI Compliant System" and Microsoft ACPI-Compliant Embedded Controller" (Intel ICH9M LPC Interface Controller) checking for driver updates online returns nothing... SAD but it is just a preview
Well My Research shows that this is beyond sad- ALL ACPI System related devices seem to be using a Microsoft generic Driver that's been around since XP SP2, not only is it lazy both on HP and Microsoft it's almost criminal, for a multitouch tablet with all its capabilities to have drivers from 2006 is really disapointing if you other TM2 owners want to pursue this further, I installed sp46869 from HP' TM2 Driver (x64) Page and ran Intel's utility and updated the Chipset package to No avail.
"Microsoft Windows Management Interface for ACPI"
Driver Date: 6/21/2006
Driver Version 6.1.7601.17514
I tried the Update Driver process on all ACPI Indentified System Devices the only remotely related new Driver found was one for "Intel(R) ICH9M-E LPC Interface Controller - 2917" which Changed it from the 2006 Microsoft Driver to the 2009 Intel Driver.
I expect a great deal more capable Convertables and Slates humming along on Win7 will not beable to install the Preview let's hope Beta and RTM fare better
And yet another update My TX2z (the prior model to the TM2) is installing just find from windows *sigh*
I'm in the same boat. It would have been great to test out the Metro UI with a touch screen.
@AnonCoward:I was getting the same error on my HP TM2T-1000 tablet when trying to load if from Windows 7....basically doing an upgrade. Once I decided that I was ok doing away with Win7, I used an external DVD drive to load Windows 8. This skips all the "preinstall checks" that Windows 8 does. It installed in about 20 minutes. I thought it hung in a couple spots, but it was just taking it's time. Works pretty decent from what I see. Touch seems to work a bit better. I need to do some more testing and try to get the ATI driver to load, using the Intel video for now.
I did as you Russ, and loaded from disk removing Win7. interesting enough there are 5 Windows Updates of which one is the AMD 4500 Driver. DO NOT INSTALL I now have no video except some Horizontal Bars, I'll have to reinstall. - My TX2z on the other hand has poor N-Trig issues (DuoSense), while I can Scroll with a finger There are no other Actions that I can do, like Alt Menu, or Select.

Why do you hate periods?
damn I love windows 8.
On my TM2-1070ca I got the same ACPI error running installer from windows.
Running installer from boot device worked for me.
Works well, running through samples and things from BUILD now.
@deadonthefloor: Can you be a bit more specific what do you mean boot device and how did you do it, i have a tm2-1010ea and i keep get the the same ACPI error.
I even tried installing the 32bit but it tells me I have to use the 64bit version.
I've installing it by mounting the .iso file on a virtual disk drive.
You're going to have to wait a while for drivers to get up to scratch on Windows 8 - although all of the Microsoft specific ones are done and several of the big name ones are on the way (NVidia, Intel etc), the lower and less critical ones like ACPI will arrive with Win8 RTM, not the beta.
ACPI is probably the most critical, the OS can't identify the hardware if ACPI isn't working properly. It doesn't need special drivers, but lots of chipsets have broken ACPI implementations and there's tons of quirks that the OS needs to work around.
Run install form Disk or USB at boot. My suggestion is to: 1) Given the Size of your hard Drive use the Disk Manager in WIN7 and Shrink your C Partion by 40G to 60G (I usually go 80G just so I can load and test APPS). 2) Leave the blank Partition alone reboot to the WIN 8 Boot media and go through the Setup and use the newly created Blank Partiton to install. This will do a couple things; Bypass any ACPI Checks and Setup a Dual boot system for you. When your done with your Testing of WIN8, remove the Partion and Extend the space back to WIN7.
Great advice from GeoffM! I also had the ACPI problem on a HP TouchSmart tm2ca, but I was able to get it loaded up using his recommendations.
Using the Windows 7 Disk Management applet (part of Computer Management), I was able to shrink my C: partition by 60 Gigs. I then tried booting from the USB stick... but Win 8 would not install because I already had 3 primary partions (sigh). Fortunately, I've never needed the HP Diagnostics, so I blew away that partition, and then after rebooting I was able to install Win 8 by doing a custom install into the empty space I created.
After doing this I ended up with wonderful dual boot.
Issue with Dell Inspiron Duo where the driver isn't found for the device ACPI\SMO8600.
