My macbook pro doesn't boot

[86rocco]

I can't boot my macbook pro.

When I try to turn it on, it beeps constantly. and that's it.

I have 2 days left of warranty and am going in for an appointment, but wanted possibly some advice before talking with the employees at the store.


I am thinking it could be RAM, HDD, or something like that.

Anyway, no other symptoms, it was not dropped and nothing spilled on it.

Specs:
2.4GHz MacBook Pro (MC374LL/A)
2.4GHz Intel Core 2 Duo
4GB
250GB Serial ATA; 5400 rpm

If anything else would be helpful I can provide information.

Thanks!!

Simple beeps mean bad RAM or RAM slot.

If it's beeping SOS in morse code, it means a hardware failure.

Could be a fried HD, RAM, possibly the logicboard.

Although I am not up on morse code, I do not think it is doing that. I will listen more closely when I get home but I think it was just constant beeping. I will search morse code to see if I can hear an example of it. I am sure I've heard it in movies before just not something I know about.

Thanks for the replies.

Yeah I learned that about a year ago when I badly seated new RAM I'd bought.

It would beep in a very specific pattern, figured it could be Morse, and it was. I laughed at that, pretty funny move by Apple.


Ah, here's an article, just found it, pertains to the iMac, but the iMac is a laptop in a screen basically: http://support.apple.com/kb/HT2538?viewlocale=en_US

Excellent, thank you.

Now I can't wait to get off work to get home to listen to this to see if it tells me anything.

I haven't taken anything apart yet so, if I suspect RAM I may try to re-seat it at least before going in to the apple store. That won't void my warranty will it?

Another good idea. It would be my luck to drive up there and not have the same symptoms.

also here are the beeping codes:

The beep codes were revised in October 1999, and have been the same since. In addition, on some models, the power LED would flash in cadence.

Beeps Meaning
1 No RAM installed
2 Incompatible RAM types
3 No good banks
4 No good boot images in the boot ROM (and/or bad sys config block)
5 Processor is not usable
