I posted this on Toughbooktalk and thought it might be useful here as well. I have one of Jeff's very nice CF-30MK2 (CF-30FCS85AM) to play with/sell. It has a Vista Business COA so I did a restore to factory. After Jeff related some of his adventures upgrading to W7, I thought I would give it a shot. The idea is to end up with everything working properly, as painless and quick as possible. I used a new Intel 240GB ssd for this experiment. What you will need to have on hand to make the job smoother is a Vista Business restore disc, Vista Service Pack 1, a W7 install disc (I used an AIO disc I made) and the Vista video driver. You can also download and install the SP1 and video driver once on the desktops. Here is Vista SP1: Download Windows Vista Service Pack 1 Five Language Standalone (KB936330) from Official Microsoft Download Center The Vista video driver, video_1930_22_d070577.exe (15.0 mb) is available from the Panasonic Japan download site. Select all drivers, CF-30, CF-30F/G(mk2), Vista and search keyword 'video'. Make sure the touchscreen setting in the BIOS is set to AUTO or TABLET before you start the install. 1. Install Vista Business from restore disc. When done, calibrate screen, for convenience. 2. Install Vista SP1 3. Uninstall the Intel Extended Thermal Model. Reboot. You reinstall it later in W7. 4. Insert the W7 disc and start the install from the desktop. To be sure there will be no other conflicts with your unit, you can run the compatibility checker. 4a. Select 'go online for updates'. 4b. Select the 'Upgrade' NOT the 'Custom' method. 5. After you have a W7 desktop do the initial MS critical updates. 6. If you find your cursor is jumpy after the updates, disable the GPS in the BIOS when you reboot. 7. Calibrate the touchscreen, using the stand alone Tablet Calibration program in Control Panel, from an admin account. It is the old XP style with 16 contact points. Do not use the calibration utility found in the Tablet PC Settings, in Control Panel for the initial calibration. Use it after you are done all the updates and installs. 8. Install the Vista video driver from Device Manager. Right click the display adapter entry and select update driver. Tell it you want to pick your hardware from a list, and once you have the Intel 965 chipset v188.8.131.524 highlighted click have disc and point it at the folder you extracted the driver to. I put mine in the C:\util\drivers\video folder. Reboot after driver install. I never got a BSOD like some have reported. YMMV. 9. Finish the MS updates, including SP1. 10. Enable the GPS in the BIOS, setting it to 'Auto'. Install the GPS registry patch when back in Windows. 11. In Device Manager I had one entry with yellow exclamation mark, PCI data acquisition something. Right click on it and select 'Update driver'. Point it at the C:\util folder. It will find and load the Intel Extended Thermal Model driver. Clean DM now. 12. At this point the OS install is done. Now load any programs you want/need. That's it. And yes you need a W7 COA to activate the OS but you do not need to do the phone activation. When you click the 'Activate now' link in the System properties window, you are asked to input the key, then the program goes online to check the key. After about 3 minutes, it should come back as genuine and be activated. All in all, I find it a lot quicker and easier than a clean install of OS and manual install of drivers and programs.

I missed this post but OP figured it out. In future Kep setting bios to defaults would have fixed this. Of course if you haven't done the GPS fix you might have to disable GPS then F10. 1. F2 to bios. 2. F9 yes to accept 3. Find Serial port portion of bios hit Enter 4. Disable GPS w/ F6. 5. F10 to save. GPS part for unit with GPS.END EDIT Thanks to Jeff for the info, help and guidance. Have phun!
