Hello to you all~ The problems I have sound unrelated, but actually are. Quite recently I started having problems with my battery in my MacBook. It's a white one, and was purchased in the UK in february 2007. I believe it is 13", as it's not as big as my dad's, his is 15", and is bigger than the 11" air's that I've been handling seem to have smaller screens. I'm running OSX 10.6.8, have 2GHz Intel Core 2 Duo processor, and have 2GB 667 MHz DDR2 SDRAM memory. (These numbers are provided by "about this mac" tab) Last week I was using my macbook, and everything was running as normal. I closed the lid of my mac. When I went back, I opened my mac, only to find that the magsafe wouldn't light up, also it wasn't charging the battery.(I don't believe it was, it might have been, but at the time I didn't check the lights underneath. The actual mac acted as though I hadn't plugged the magsafe in.) Everything was turned on, my house power lines are fine etc. My magsafe works absolutely fine on my dad's macbook. After I re-started the mac, the computer started acting normally again. But a few days later the problem returned. Restarting worked once, then a few hours later the same thing happened, and restarting did nothing. I unplugged the magsafe at the wall and plugged it back in, and it worked again. The next day it wouldn't work at all, so I started using my dads magsafe, and that worked, until my mac randomly decided it didn't want to accept it. (I've been trying different power outlets in my house, both upstairs and downstairs, nothing makes any difference) I started looking for help online. One person who seemed to have a similar issue said that they had rapidly removed and inserted the magsafe a few times, and that caused the magsafe to act like it was behaving. It went green for a few seconds, before changing to orange. But the icon on the top bar said that the mac was still running from battery. After a minuet of saying this, it changed (without me touching it) to say it was charging the battery, but running from the power adapter, which is what it usually says. I unplugged the magsafe, but the software said it was still running from Power Adapter, for about a minuet, until it changed to battery. I popped the magsafe in again, the software still said battery, but the lights on the actual battery were charging. Reading on from the first poster, someone else said they had the same problem, and that the people at the apple store had said the problem was a corrupted sleep image. (the actual thread is here: http://forums.macrumors.com/showthread.php?t=1291860 ) I went to delete the sleep image, and this is where the Terminal lockdown comes in. I forgot to change accounts to admin, and when prompted for my password, I entered my day-to-day user account password. Terminal told me that this was not the correct password, and that it would send a report out. Then a pop-up appeared "Do you want the application "Master" to accept incoming network connection?" This scared me, so I went to google exactly what master was, but whilst searching, the pop-up window closed itself. I then logged onto the admin account to try again, but when I tried to enter my admin password, it wouldn't register it - as if I wasn't pressing the keys (I could cancel the command with "ctrl+c", then enter other letters, it was just the password bay it would't accept for). I restarted the mac but it did the same thing. On all user accounts, it won't accept the password. I guess what I'm saying is: I've gaffed up majorly with Terminal. I don't use it too much, and I'm trying to avoid a wipe+OSX install. If anyone has any help or advice it would be greatly appreciated, but I understand if there's not; that was the only article that I could find, although maybe that's because I'm not very good googling. It just doesn't seem like a common issue. And I'm sorry if I've rambled or if this post is too long, I've tried to include everything, although I'm probably missing a lot of stuff, and if you ask for information then I'll happily provide it, as long as I know how to get it (I'm not overly great with computers, it's the reason I was sold on mac's in the first place.) -oh, I almost forgot: I've done a check and repair on disk utilities. It's something like "<something> permissions" and "repair permissions" That didn't solve it, but I did that before I did the rapid unplug/plug thing, so maybe it was that that solved it, or maybe it was the unplugging. I don't know. Thank you for taking the time to read this, I genuinely do appreciate it.
