Random Crashes, no boot, now no sign after trying all suggestions
I need help, I have no sign on my MBP. I live in the countryside in Portugal and no where near an Apple store, so I've been trying to read and learn as much as possible. I did take it to a computer repair shop in the nearby town, but they didn't want to risk a diagnosis because they were dealing with a Mac. They said it could be the battery or the logic board.
Let me be as specific as possible about the problem I'm facing .
I bought it from a friend around May this year (2016) . He only used it in his office and it was all working fine (a dent near the megsafe worried me, but in the shop they told me there is no damage). I don't think he used many "heavy" programs with it. He had installed recently the "new" OS "El Capitain".
The MBP came to me working and no signs of crashings. I bought it to work specifically with iVideo and AutoCad, so I installed the programs... The HD has 250GB I think, but only 4GB of RAM ... Not sure if it has anything to do with that, but as I was using iVideo, the computer randomly chashed... the battery was holding at least 3h, and at that time it was about 30%... there was no overheating, so I had no idea... from that time on, it crashed randomly a few more times and then it was mostly while booting... it wouldn't boot completely without crashing and I had to insist to get it going... I started to always be plugged in and that seemed to be better than with only the battery, even if it was fully charged... I even got a used battery just to check if the battery was the problem, but it was the same... Then I started to think if it had anything to do with the fact that I don't use 240v to charge, but a solar system with a cigarette lighter (like in a car) with a 18.5v 85w car charger ... I tried to find one of those from Apple, and they don't do it, so that made me think if they don't do it, because it's not recommendable :-( ...
So, that's the story. When I eventually make it start, it works fine ( I keep it plugged in), I shut it down normally, then next day, there's no sign... I open the back, unplug the battery, plugged back in, and there is sign... but I have to insist several crashes until I get it going :-(
I have reset several times SMC and PRAM. I would like to try to test the RAM, but I can't find a free program, and when I press power + D, or power+option+D , there is no hardware test...
Once, like now, after unplugging the battery, there was still no sign, and I tried another thing I read...Unplugging the battery, unplugging megsafe, hold power for 10sec, while holding power I insert the megsafe and count 10sec, then I released and count 10sec. when I turned it on normally, there was sign again.
Now I tried the same, but it didn't work... DID I KILL MY MBP ? :-(
Questa è una buona domanda?
