MacBook Pro does not boot

I am having the same problem with my macbook,my fix was to take the ram out of the right slot,i tried both cards in the left,both work,with either in the right,it just sits at the white light.same with both in.if you have both cards in,try holding the laptop up,and putting pressure around the screw in the middle of the laptop,then power on while holding it. it should power on,but as soon as the pressure is removed,it will kernel panic,i took the keyboard off to look at the ram slot to see if there was anything wrong visible,but snapped the keyboard cable in the process.i looked the pinout up on the internet,and wired an old imac keyboard to the internal keyboard connector,hit the powerbutton,and it turned on,so right now,i have a plastic clamp on the right ram slot,and have my macbook set up as a desktop.the pressure in the middle should bring it to life to recover data,but is not a permanant solution.

no solution to the main problem,but hold the mouse button in and power on to remove the cd/dvd

Having a problem with my macbook pro. I just got the IPod Touch and was charging it from my MBP when the screen just died. I immediatly turned it off but now when I press the power button, a white screen appears with an apple icon in the middle and a small cirle on the bottom that is like a timer. I thought that the computer might be downloading something, but I left it on for an hour and the computer didn't get out of that mode. I have tried several things such as the installation cd, first aid repair, but both said repairs weren't needed and that the drives were fine. Any suggestions on why the computer is doing this? It's been several days and I shut if off, leave it off for an entire day and when I turn it on, the same screen with the apple appears and nothing else.

Please Help!!!!!!

hi
today when I woke up and try to wake up my MBP it shut down and then it restart itself but the only think that appears is the apple logo and something spining around and it restarts again then I turn it off and since I also installed windows vista I tried to turn on the MBP starting up with windows and everything is fine over the windows side only my Leopard OS is not working, I was wondering if you have any suggestion to this common problem???????HELP

How did you fix your problem with the "? inside the folder". My son's computer is doing the same thing...Any help would be greatly appreciated......tia

I've got a similar problem. New MBP 2.2, OSX.5, had 4GB RAM & 7.2K rpm Seagate 200Gb installed by Apple resellers.
1st I noticed permission repair took over an hour (max 1 minute under OSX.4). After I tried to access my XP drive via Parallel + BootCamp, the laptop won't start under OSX.5; the gong sounds, the wheel starts spinning and after two minutes it restarts. It's a continuous loop. The book starts fine under XP, and my OSX.5 copy on a FW-disk, made thru Xupport.
Then I did a complete re-install, everything was fine, again until I tried to access XP via Bootcamp. Now I am back to square one.
Anyone, any ideas please??
After 15 years of Mac I am seriously considering switching to XP.....

same problem w/ MBP;
light on,
fan on,
harddrive on (I guess),
nothing else.

has Apply said anything about it yet????

This is the second time I get the problem everyone in this thread seems to get. Solution from Mac is to reinstall the whole Operating System. Wow thanx a lot for that easy response, and customer service also ignores the problem and talks about hardware issue, or turn in our computer and change the harddrive.

The thing is I lost 1 months of valuable work (£2 million project) for an Advertising Agency (do I get compensated..now way it is my fault according to Mac) and No it got nothing to do with the computer it is software issue since, Windows Vista is working more stable than OSX Leopard.

I have been so frustated from the arrogance and ignorance from Apple, their customer service is really unhelpful... I will convince my whole department to change to a more reliable system, ironically to Windows.

Why don't they try to explain the problem somewhere..

Hey guys, I have the same problem, but I have a little more information about mine.

I put mine into verbose mode (CMD + V), and I found the problem. The computer gets stuck in a loop attempting to initialize the mDNSResponder Daemon. I don't know what to do from there though. It all started with a simple software update and then a crash.

Any ideas?

My problem is similar to the first poster with the exception that my light near the latch release is blinking. This all started after updating the Leopard OS, Parallels, Windows XP, iTunes and iPod, Quicktime and whatever else Apple has that needed updating. Everything seemed to be working fine after that 6 hour exercise but 3 days later I go to turn it on and nothing. Went through all the steps in the booklet, resetting the RAM, checking the power, reinstalling the RAM. Still nothing. I get a sound from the optical drive, no chime, and then the blinking light near the latch release. Tried inserting the original OS CD and restarting but still nothing with the exception that now I can't remove that CD. I'm in Kuwait so my repair options are limited.

Well, my original problem had been solved by apple REPLACING my hard drive. It failed, probably due to a heat problem. apple care replaced the drive, but charged me for preserving data.

Since I've gotten it back... (1 week) it was fine. However, paying $180 to the apple care dealer (creative computers) to preserve the data on a factory supplied hd truly *****.

Hi Brnzwngs, were you able to fix the problem? I'm curios.

I got the same problem after a routine update. When I clicked Restart, all I got is the grey screen and the spinning gears. Not sure which way to go.

Hi I'm having some problems trying to boot my Macbook Pro, the message saying your start up disc is nearly full kept on appearing so I changed my start up disc some how. Now ever time I boot the grey screen appears and just a flashing dark grey folder icon with a question mark in it. Can anyone advise me on how to sort this out? Thanks
