This magnet when the screen is closed lays on the touch pad behind which is a magnetic sensor that puts the computer to sleep.

I did not know this when i took the screen apart and just took it off and taped it on my new screen in the middle where it supposedly was on the old one. But its actually a very specific spot.

So props to apple for a very ingenious solution to a cool problem.

Suck that it doesnt sleep with the closed lid forcing me to press sleep in the system. No biggie really just kinda sucks to find out now.

Im not gonna split the panel again, its only designed to be put together not taken apart and if I split it again im afraid it wont come together at all and the chances me damaging the new LCD screen are very high.
would an install/upgrade manual help?

um only if u have a messenger bag that allows the vents on the rear to point up and be uncovered. i used to do the same thing w/ my old compaq, but i made sure the vent was clear and that the system wasn't doing anything intensive (usually just playing music, piped to my car stereo). so yeh, regardless of brand make sure to keep it ventilated otherwise yer asking for cooked components.

I have been around computers and laptops in particular so long that I have already gone through the many misconceptions people have about them. You would be surprised but you can leave a laptop in your bag working without air and nothing will happen. laptops especially are built to such high tolerances compared to PC's that laying inside a bag with no air will never cause any damage to it.

I have left my Dell 700M in my book bag on for hours and hours at a time in a locker to download stuff without any problems. I am certain that this apple can handle the same. I will test it out. I am sure it has a heat failsafe circuit built in to prevent damage.

the 700m is also quite a bit more roomy in re: to how it's internal components are put together. Apple's are very tightly packed and regardless of what a computer can do, it's generally good practice to take care of your system. given the time u've had to do away with all the misconceptions most seeming "simpletons" adhere to, u must also be aware of the various altitude, moisture, and temperature impacts on hardware operation. i'm guessing the specifications are developed by tossing stones into a corner and decrypted based on how they fall. i have looked up heat specs for the hard drive i installed and found that the fans kick on to basically protect that threshold (as well as that of the older slower drive, same specs heat-wise), but even so it gets close or up to maximum specs under heavy load. in the past i have inadvertantly left my compaq running w/o ventilation in a bag and it did fine. it doesn't mean however i would consider it as being beneficial or even benign for the system to endure in deliberate fashion, even if heat management circuits r built in. i wouldn't care to personally see if i could go over the manufacturer's heat specs for kicks, but if that floats your boat it's your hardware.
