I have a 2008 Macbook Pro 15" (2.5 GHz Core 2 Duo, 4GB ram), with Lion installed. I also have a Boot Camp partition with Windows 7 installed. A few days ago I downloaded the trial version of VMWare Fusion 4.1 and set up my existing Boot Camp installation as a VM. Installed it with no problems, and installed VMWare Tools. It ran decently for a little bit, but then things started going wrong... 1) My fans constantly run at the max speed of 6000, even though iStatPro shows my CPU at 90F-110F. 2) iStat started showing the temperatures for "Heatsink A" and "Heatsink B" - these are two that never showed up before. Heatsink B gets up to 259F, which I suspect might have something to do with the fan speed. My computer is not actually hot though (definitely not boiling hot; and I don't think 259F is really possible), and when I use SMCFanController to force the fans to 4000, I don't have any overheating problems. 3) The serious problem: when I try to wake the computer from sleep, it shuts down. Pressing the power button starts it for a second, and then it shuts down again. I have to hold the power button for 5-10 seconds and wait for the light to flicker before it actually turns on again. 4) This also happens when I shut the computer down. If I want to turn it back on, I have to force it back on by holding the power button. Restarting it works fine, though. 5) These problems exist when booted into both Lion AND Windows 7. -I tried a PRAM reset, SMC reset, and disk permission repair. As usual, those did nothing. -I tried uninstalling VMWare. I had to use AppZapper because there was no VMWare uninstaller on my computer, or in the .DMG image. I really don't know why...I looked everywhere for the uninstaller and tried redownloading the image file, but in the end, I had to forcibly delete all of the files (and I'm not sure that I got everything). No change after the uninstall. There is a chance that VMWare didn't cause this, but I'm fairly certain it did. My computer has been fine for months and the only recent change was VMWare - the problems occurred immediately after installation. I can't find any other users having this problem on the VMWare forums, and for some reason, VMWare isn't letting me log onto their forums, so I can't ask there. Do any of you have any ideas? I'd really appreciate it! Please let me know if you need me to post any more info.
