Hi everyone. Please help me, i hope my mac is not broken. It's not booting up. Here's what hapenned.

My mac was in sleep mode, i put it in it's bag and put the bag to the trunk of my car. It was also snowing and weather was 25 degrees fahrenheit. (-3 celcius) it was like that in my car for 2 hours and i came home, brought the bag upstairs, took it out of it's bag, it was amazingly cold. It didn't wake up.

I plugged it in, turned it off with the button, turned it on and showed a huge green screen for a second than i hear the boot up sound, apple logo appears, loads the os and when it's time to select a user screen goes blank. I can turn on the volume etc all that is doable but can't see my screen.

It's been almost an hour now and it's not cold anymore. Same thing happens. Can't boot it up. Also screen flikers when it's on the apple logo in the bootup. I've searched all over the net, tried running apple hardware test from the disc but screen shows nothing on that too. I've tried resetting vram, pram that didn't work.

Called apple and they didn't help cause i havent got apple care.

Please help me, any help is appriciated. My mac is 2010 15" macbook pro btw.

Thanks in advance to all answers, i am writing this from my phone.
 
I can't remember if the 2010 model has the removable battery or not. If it does remove the battery and keep the MacBook Pro plugged in for 2 hours to "warm up" then turn it on without the battery in and see if that works.

If the battery isn't removable just let it charge for 3-4 hours to warm up before attempting to turn it on. Also try resetting the PRAM when you boot.

Best of luck and keep us updated!

Battery is not removable and it's quite warm right now. Above warm actually. Normal running temprsture of it. It's been also plugged in for almost an hour now.

It's so weird, i can turn up/down the volume. Can hear the sounds of it when you change it. Can change brightness. But it's black screen. Just a little black light and i can change that light's brightness. I dont think my screen is dead cause apple logo is visible when botting. It's so weird.

Any ideas to this weirdo case.
 
Would be interesting to know the minimum temperature a MBP can operate and be stored at.

Mine has been left in my car and it was around -8 outside and it worked perfectly fine straight after wards.

I didn't realise it was going to be that cold, but I guess I was just lucky.

This is getting even more interesting. I booted it in safe mode again and connected it to my tv with hdmi cable. While connecting it screen turns blue for a second. Screen opens normally just for a second and it goes black again. However for tv everything is normal. Unfortunately it's not set to mirror image it. It's like a second display so i see a blank wallpaper. Can't
Open system preferences or anything cause i can't see the main screen.

Please help me on this interesting case i really need help
 
Is the computer itself still cold to the touch? When I would drive home leaving my computer in the car for a couple of hours it would be freezing! The computer would always start but it would be really slow and sluggish.

If it's still really cold, I would wait until the body warms up a little bit more before trying to do too much.

no on the contrary it's hot right now. But it's normal hot not overheating.

What's more interesting is i just managed to open system preferences from the Apple menu by just plugging the dvi cable in/out for gazillion times and seeing it for just one second on each of them. Then i set the display to mirror it rather than setting as an extension of the first screen. It's a success and a patience story but i managed to do it. So i can see my computer from my tv screen just normal now and everything is perfect. Macbook Pro screen is still black though.

What's the problem it's killing me. I thought it was motherboard or gnu but after connecting with the tv and seeing everything normal it can't be. It can't be the lcd neither cause it shows it for one second in between plugging the dvi cable and also it shows the apple logo on the boot up.

What is this?

I want to run the apple hardware test but i can't without the screen. Gosh, hopeless.

I wouldn't keep blindly trouble shooting at this point. Something isn't right here and I would either call Apple and explain the situation, but they are most likely going to have you bring you computer in to get it looked at.

what's the number of apple, i called apple care and they told me to buy an apple care or hang up.

Any other free apple support lines?

Also to sum up,

-It's not the motherboard or gpu cause everything is fine on external monitor
-It isn't the lcd or cables going to the lcd cause it shows the apple logo and shows the screen for just a second when plugging the cable to connect it to the tv.

Anyone have any idea what else can i do?
 
Bringing a cold object into a warmer location can lead to moisture being condensed on the unit (or in the unit). Old timers may remember that VCRs used to have a DEW warning light on the panel for just such a situation.

The cold itself probably wouldn't have been an issue, but the moisture would be potentially. Is/was your home fairly humid? Would have been if someone recently took a shower or was boiling pasta on the stove. When that cold laptop came into that environment it would attract moisture like an ice cold drink in the summertime!

That being said, I have no solution for you, but just maybe a source of the problem?

Thanks for all your answers but we still havent got a solution. There isn't moist in my house. Also i called apple from the number you gave, they asked for my serial number and told me i have to buy a support plan for 49 bucks to use support for once.

Can't this be a software issue? If there weren't any signals from my computer to the screen than it wouldnt show it for even that one second while plugging. Can't be anything wrong with gpu or mother board or lcd neither cause eveything is normal on external tv.

Anyone have any ideas?

You keep saying that there is nothing wrong with the LCD. There clearly is if it isn't showing anythign on the screen without it being plugged into an external monitor. This is something hardware and not software related. Your best bet is to bring it into an Apple store if you can.
 
i just dropped it off to an Apple technical service. It's unfortunately out of warranty since June 2011. And it will take them at least until monday or tuesday to diagnose what's wrong.

So my life has come to an halt, assignments will not be made quite easily, no research, no fun etc... MY life went back 10 years...
