It's a temperature sensor error, usually the fans run at maximum rpm when this happens. The error indicates the LCD temp sensor is either reporting out of range data, is disconnected, or has failed. It is probably a damaged or disconnected sensor cable. A disconnected or missing sensor would simply force the fan(s) to run fast to protect the system.

Hi Tricia, under normal circumstances, when doing an installation on a hard-drive already containing a previous windows installed partition, all files and folders will be placed in a *windows.old* folder on your (C:) drive. in your dilemma i see one of 2 options, option 1) get a copy of *HIRENS BOOT CD* and boot from this, copying all your data to an external source, this can be done via USB or CD which ever you prefer, Option 2) although the easiest way to get out of this problem is to do a completely new installation on your system, however this way you might lose data if it is not from a windows 7 OS to another. if you need more advise, please do ask :-)

If its the wrong one, then don't delete it. If its the right one, then delete it.. Who knows, since you clearly have not provided enough information to make any sense whatsoever.

Apple will not reset your drive (unlike every other hardware manufacturer on the planet), so once you have changed your region code 5 times, that's it... sorry.

Simply you can't alone, probably you have problems with your southbridge on motherboard. Usualy this can be solved with rebaling. Is a common problem because - probably - you not clean your mac regulary.

heatsink not contacting CPU or GPU... fatal

Assuming you had a working machine prior to cleaning it, I would suggest you visit this site to follow instructions for the 27". The procedures are very similar (and nothing currently available specific to 21.5 yet) Understand that the process requires very tedious gentle handling of several cable connections that CAN EASILY BE DAMAGED if you are not extremely careful. I have performed several disassembly procedures on these models and they MUST be done with the proper tools and precise attention to detail. If not you can easily damage the delicate connections. Every screw, fastener, piece of tape, has a specific purpose and any item left out will likely result in a failure. Retrace your steps using the instructional guide (linked to above) and you may yet save the day. good luck and take a deep breath before starting!

Problem: Your Mac got locked via iCloud and on boot displays "Enter your system lock PIN code to unlock this Mac." It also sets an unknown password on the firmware so you can't boot from a disc. And you don't know the PIN code for a variety of reasons (not my business). Solution: Mount the locked drive on another machine, find the PIN, re-install the locked drive into the original Mac, enter the PIN, resume your business. Tutorial: *I'm going to post the steps I did in my case and suggest steps you might take if your case varies. Things Needed: 1. Alternate machine with space to mount an additional drive. (works on Mac or PC*) *If you're using a PC, you'll need to download and install Mac Drive to be able to read the contents from a Windows environment. 2. You might need a SATA to USB adapter if you have a laptop without room for an additional drive. 3. Screw driver to disassemble the Mac. Step 1: Remove the locked hard drive from your Mac. You can find detailed guides for your specific machine at http://www.ifixit.com/Device/Mac Step 2: Install the drive into your alternate machine. But make sure you do *not* boot from it. Boot from your regular drive. If you do not have an alternate machine, feel free to ask a tech buddy of yours to lend you their machine. Step 3: Once booted into the alternate system, locate your locked drive. In my case it was drive D: on Windows. Now browse to \Users\username\Library\Application Support\iCloud Step 4: In the folder "iCloud" find a file named with a bunch of numbers: ##########.lock In my case it was: 1138515150.lock Step 5: I'd suggest that you take a picture of this file name for accurate reference. But you can also just write it down. Step 6: Once you got the number, power down the machine and remove the locked drive. Step 7: Install the locked drive back into the original locked Mac. Follow your iFixit guide from Step 1 in reverse to put the drive back. *It is important that you put it back in the machine where it was originally locked* so that the motherboard firmware will be unlocked in the next step. Step 8: Boot up the locked Mac and referencing the number you recorded, you can start trying 4 numbers at a time for the PIN. Try the first 4, then the second 4, and so on.. For example: 1138, 1385, 3851, 8515, 5151, 1515, 5150. In my case the PIN was the second to last 4 digits: 1515 If you typed in more than 10 combinations, then it says that you are locked out for a minute. Just restart the machine and continue entering the combinations from where you left off. Once you enter the right PIN, the Mac will instantly reboot proceeding to where you were at when the lockout occurred. It will also remove the firmware password.
