Well, I have been having charging problems for a long while. Over a year almost infact. I have a black macbook 4,1 (early 2008) (This problem happend with 10.6 and 10.7 I have no clue about 10.5 as it never was a problem back then. Also while im writing this its charging for some reason. Seems to do it alot. I do tend to move rooms alot and move around with the computer and thats how it gets drained. Well First my bat, expanded and made my mouse unusable. unless it was out of the system. Great EH? So I ordered a OWC replacement one. got it in augest \ sept of last year It works great. but the last little while I have been having strange charge problems. The original Charger that came with the system would not give a charge to the system if it was plugged in (No light on it - Some times a dim green) So I went to apple this febuary. One of the guys at the bar said my battire is fine even though its third party. But he gave me a new charging brick (60watt) (same as the old one) Well I have the same problems with this charging brick and its now early may. I've Reset the SMC, PRAM, I use the system till the batt is drained but it refuses to charge even then if its at 5% some times. If it is charging the Light on the new charger may not show or it may show. It seems to be pickey if its on or off. The green light refuses to work at all for me. I seen it on about five times. I tried both ways to have the mag safe in but I have to replug it about 10 times to get something. I have attached with this post a picture of cocunet Batt and my Istat Bat Reading. They seem to be the same. I have looked at buying a MPB charger to see if it may be a low watt problem with the 60 watt as my system could be pulling more then I think. My house plugs are all fine as this happens when I'm out and about also. I live in canada so my Power is 110V and 60Herts (the adaptor is good for that) So theres no problem with a mis match. The only thing is that I can come down to is the DC board or charge Board is geting old. Also Side note my fan always runs very loud. when I'm not running anything. It seems to do it once in a while now. after the .7.4 update.

But Depnding on what is going on with this one, I may invest in a new Macbook pro. I am wanting to buy another pc tower though. So it all depends on how cheap the fix is over here for this annoying charge problem. As I could go another year with the same laptop, as I need a desktop windows system. Hate Boot Camp with a pasion! Plus I cant do what I need to in windows on this old system, like mass dvd burning if my burner is shot. So what can I do to prolong the life of this system to make it charge properly again?
