MacBook Pro completely dead
The laptop has no hard drive in it.
The battery is gone, it says it is charging it and it seems to do so in about 1hour and 40minutes, but when I unplug the MagSafe it goes in hibernation after few seconds.
I started this laptop several times with no problems.
Before investing in a new hard drive I tried the pc for a whole afternoon with ubuntu12.04 cd.
Everything was fine, I then shut the pc down and maybe that's when something went wrong:
the ubuntu logo only was showing as normal, but the pc wouldn't turn off.
After a couple of minutes I decide to force it and I switch the pc off holding the power button.
That was the last time I've seen the pc alive, no other minor signs of life since then.
MagSafe is showing orange light with battery installed, green without.
I tried SMC resetting.
I tried moving and switching the RAM.
I tried shorting the power-on pads.
Now I'm trying iFixIt as a last resort.
Thank you very much to all for your help
