Alright I received my refurbished 2.4GHz MacBook Pro with 256 Vram in the mail a few days ago. Since then I've had 3 reoccurring problems that are extremely annoying.. 1. The MBP will not hold a WiFi connection. The AirPort is always in scanning mode. It'll stay online for a few moments, then it'll disconnect and it just keeps repeating this cycle. I know it's not my router because I've tried it with other ones and it's the same issue each time. I know these don't have as good of range as the MacBook's, but I don't think thats the issue here. This is the most serious of all the problems, so any help would be appreciated!+ 2. The MBP will not always load up after being in sleep mode. I've read this is a common issue, but have yet to find a solution. This happens when I wake the computer up from sleep mode. The screen just stays black, but you can hear the SuperDrive boot up. It does load after a minute or two, but it is still extremely annoying. I've read it might have to do with the keyboard firmware update?+ 3. At random times the computer will drastically slow down and become very "jumpy". This is an odd issue I haven't seen anywhere else. Its happened twice now and pretty much the computer slows down and the cursor becomes very jumpy and not smooth. I have checked iStat and it says I have plenty of resources left, so there's no reason it should be slowing down. I did install 4 gigs of RAM in it, but the computer reads it fine and I installed it correctly. I doubt that's the issue, but figured I'd throw it out there.+ Sorry for the long thread, but these are really messing things up. This is my first Mac and I'm hoping these can all be easily solved. Should make a Genius Bar appointment? Thanks again!
