Dead during replacement/formatting of hard drive

My MacBook pro seems to need a new logic board. I didn't want to send it to Apple with confidential stuff on the hard drive. A friend loaned me his MacBook pro that is his backup for traveling so I could put my hard drive into his MBP and reformat/install os again. I had it apart and had my hard drive in. During the reformat process, the laptop shut off and is now dead. No amber light on charger at all. I am not sure what happened. I also noticed that my MBP, which would not start but would charge will also no longer charge; no amber light.

Is there some fsilsafe that kicked in when I had the keyboard off??? I have reinstalled his HD and put all screws back in but still no charge on AC. When I was doing all of this, i had it running off AC with no battery installed. The power cord was attached the whole time and no one came near it during the reformat of my drive in his MBP.

Does anyone know what happened and why is affecting the charging/powering of both laptops???

Just some info: his battery is brand new. I tried 2 85W chargers. I tried SMC and PRAM reset. No power at all so no install DVD option.

You've got to many things going on here. First let me say that I seriously doubt that any Apple technician would take the time to even look at the contents of your hard drive. If you had come here first you might not be in this fix. The assumption of a bad logic board is almost always incorrect. An external adapter or hard drive enclosure would have given you access to the drive. With the original charger showing no light and two subsequent chargers not working I would suspect the wall plug. Check your breaker.

Since your friends unit was working, that's the one to go after first. Do you get any light on the magsafes when you plug it into the Book? Do this without the battery in and see if it will boot.

Not the wall plug. Used different ones and tried other devices plugged in. The laptops are even plugged into different outlets on different circuits andnd neither are charging. 7 hours later both batteries are now drained. I also spent 5 hours online researching the initial issues with my laptop.
