How to disable some of the built in memory?

How was that rude

Thats the core of the problem - you don't even see the problem. Once again - good luck to you.

Hi all, first post and hope there is a solution.
Okay, late 2010 macbook air, glitched OSX installation that freezes at initial apple boot-up screen. Has efi password (set by seller) and so I dont seem to have any options to correct problems, ie:cdrom boot, etc., or key-combos. Ive been using this notebook for a little over six months without issue and being my first macintosh i simply pushed the power button and everything worked - what i heard and why i wanted a mac! Ive read alot of different posts and tried to educate myself as best i could on this issue and now Im thinking I either got totally duped into buying a notebook with a very expensive problem or worse, possibly stolen notebook. After reading a few other posts like this one, i thought i should check the serial number and make a few phone calls. its partially worn off (rubbed off?) and so was then weighing jail terms against money lost - no brainer there - but read about the 'two jumper pads' in this post above and, back to my initial reasoning, would be able to read the serial number from the operating system, recover my personal and work files, determine the notebooks status and - if needed - pursue the seller and my money back before turning it over to the local boys in blue. The notebook has an ssd hard drive (stick?) and a very different interface from ide 'pins' or sata 'slots' that im a bit familiar with. My first thought was simply remove the hard drive and let 'others' figure out its status. Any help or suggestions would be very much appreciated

EFI reset on Logicboard Macbook pro early2008

So, after a few days searching i just found your argueing ´bout the password reset for the air.
As my problem is different i excuse myself for entering with the argument that i wheter find at last a solution or throw my logicboard away.

I ****ed up my Macbook pro early 2008 A1150 (intel)
with a tool called ONYX, i used this tool several times in this last 4 years, but as
my macbook started to hang around in shutdown and dislikes to stay in sleep (no, not cause of usb devices, thanks)
i asked the ONYX to clear all : caches, indexes, temp files, etc.
it asked me back to reboot between some actions, but as some profound selfconsiousness of mine i told it to work through, i would start later .
It did what i sayed, but....
oh surpise, after the reboot my logicboard was instantly ****ed up ..
..indeed it was a surprise, i thought, "in worst case i set up a fresh install of osx" so WTF.
Now, to shorten the story: THE TECH DETAILS:

1. No Hardware Problems at all, before using software ONYX
2. After the reboot, NO BOOTING - Power for HD+DVD+FANS+SLEEPLIGHT
3. no Screen, no Backlight, no Boot-peep, no further HD-Action, nor possibilities to Network boot or DVD boot
4. RESETS: SMC, NVRAM, (and PRAM) (there wheren´t any reactions to it) everything about 5 times
5. openend the MCB and disonnected and reconnected every cable (I tested if it reacts on disconnecting the temp sensors =YES - so its still kind of working)

and now 6. APPLE Service wants 700€ for a new logicboard and work, and seems to have no idea what else could be done except changing the stuff to a new one, very boring of these guys..

here it comes to the end:
I get a used one for less than 500 bucks, so what do i want
..-> its hurting me that the problem seems so near to me, cause it should be just a software ****ed EFI in my midclasstechie view.
It should be not a big deal. Should it

POINT -> Is there a way to reset or flash the EFI hardware based, like shorten pins (I didn´t locate it yet at all) ?

I think thats it. Ah yes, indeed I did all updates, so there always was the newest version in the EFI, but please don´t ask me which one, the last one 2 weeks ago that was allowed to come with 10.6.7.
Thanks for any supportive idea
Otherwise the ebay gets the parts........and me an very fat disillusion
greets

Whoa there - just trying to help. Shorting out random pins on your logicboard may seem like a logical and rational way to proceed to you, but you are likely alone there. Next time I'll ignore your questions rather than be called condescending and ignorant for trying to help. Good luck to you.

I think many of the posts here come off as condescending.

You know nothing about the OP but assume he's an idiot. Perhaps he is an engineer and using an old MBA for some a typical purpose.

Wow aren't you rude to people who were trying to help you.

I see very little help here.

Thats the core of the problem - you don't even see the problem. Once again - good luck to you.

Condecending.

waste of time, there are no geniuses that would go out of their way and not follow guidelines. He'll be liable and probably be rebuked by the store manager. Besides, it's out of warranty and they won't even touch it unless it was a dead simple fix.

The macbook air is already out of commission, so there are no negatives to learning and trying new things on the logic board.

No, it's not stolen. Lay off of the skepticism.

Lets get back on topic shall we and stop suggesting that i bring it to the store.

x2.

Including you, they are not helping. Who cares if someone wants to tinker & learn a little in the process. For all anyone knows, it could be a school project.

Hey guys, don´t you wanna stop this. It´s boring.

So if he doesn´t get his password recovery, fine. bye to you "idonot..whatever"
The thread is anyway from last year, so what?

Cause it seems that here is someone reading, i ask, whats about my question.
is there a chance to repair a software broken efi chip with shortening some pins or something special other trick?
