Can't install OS - keyboard/trackpad issues
Hi all,
Although I check this site often, this is the first time I haven't just found the answer to my problem with a search. I've got a bit of a story to tell on this machine.
My partner had a 17" Unibody MacBook Pro (4-core i7 2.66, Mid-2010. Current RAM 16 GB, I've tried both a 1TB Western Digital Blue HDD and a 500 GB Samsung 840 EVO SSD with the same results). A few months back, he spilled liquid in it and it became inoperable. It appeared clear that it needed a new keyboard.
Once I installed the new keyboard, the trackpad had no response. So I also installed a new trackpad. Neither the trackpad nor the keyboard seem to respond, except that holding down "alt" while booting does give me the drive selection menu, and that the power button is responding.
I have tried resetting the SMC and non-volitile RAM, but that does not seem to have any effect. Still no response from either keyboard or mouse.
So, after all of that, I decided that I was fine using this as my home server - with a USB keyboard and mouse.
With a USB keyboard and mouse, the machine boots to the Yosemite installer (on a flash drive.) I am able to run Disk Utility and format or partition the SSD. After re-formatting, I was able to start the Yosemite installer. After about 20 minutes or so, the installer re-boots - back to the Yosemite Installer. With no indication that it did a thing to my SSD.
I also tried the same thing with a spinning HDD that I had in the drawer with the same results.
Any suggestions to get this machine working again? I'd love to have keyboard and trackpad working again as well, but if I could get it working even as a desktop, I would love to have it back up and running. I'm on a student budget, and this was by far our fastest machine. I hate to see it lingering on the repair shelf...

Questa è una buona domanda?

First lets see if we can double check what your model is. Can you give us the last four digits of your systems serial number so we can correctly ID your system.

Just wanted to add the following information:
The computer must be seeing the keyboard on some level, because the following works without a USB connection:
Power button
Holding "Alt" to choose boot drive
Selecting boot drive using arrow keys.
Hitting return to boot.
Once an installer boots, I cannot get any function from the keyboard.
I don't know how to get a serial number for you when I can't boot the machine - there is no "about this Mac" display in the installer.

And the minute I posted that, I realized that "duh, the serial is inside the machine." Last 4: DD6Y

Please note that, while I found the first two answers helpful in ruling out root causes, this issue is still not solved. Any additional suggestions are welcome.
