[QUOTE="sailingthrough, post: 1609991, member: 330982"] I'm trying to fix my friend's A1150 which has just stopped booting up. Turn it on and we get to the question mark folder icon, and if I boot it up in target disk mode the drive does not appear to mount. However, I can hold Alt to access Startup Manager and view either a USB stick with an OSX Mavericks installer, or my own MacBook Pro in target disk mode... selecting any of these results in going back to the question mark folder icon. In short, it won't boot from any drive/partition that I have tried. I do not have access to an OSX install disk. I have tried removing the RAM to check if it's the logic board, and removing the RAM and attempting to boot results in the front LED flashing (the one on the lid open button) but no beeping. Could it be a fried logic board? Any ideas? EDIT: Apologies if this is in the wrong forum, but as the laptop powers on and at least gets to the grey screen I figured it could be a software issue...
