Once power is drained I can plug battery in and when I plug in magsafe the machine will boot, see and charge the battery. Once I shut machine down and press power button to turn the computer back on, the amber on magsafe turns green for a second then amber again. No power. Have to remove battery...
Sorry Duke I guess I wasnt using Real charger before on that last post. looked real at first glance. Too much crap on my desk, had to organize. Now, with Real charger the Machine will turn on when plugging in magsafe. But only turns on when plugging in magsafe without battery plugged in. Will...
Starts at 7.01 MOhm and slowly drops down. Held probes there until 4.75 MOhm then got tired of holding them. Went to check 3v3_s5, plugged in magsafe and battery and the fucking fan is spinning. I swear I didn't do it. So now when Battery and charger plugged I get fan spin. If I turn it off it...
I have a 2012 A1278 that Very intermittently will have flickering lines across the screen and sometimes may freeze. Customer says that it happens very quickly and randomly. I myself however didn't experience it until I tilted it backwards from under trackpad. I thought it could be an LCD cable...
G3H Starts at 1.9V and drains slowly to 0
PP3v42 - 3.41
G3H Resistance in Diode mode - 0.440
Board looks like it has been worked on before. Flux around U9600 and U7201.
Thanks in advance.
update: went digging for copper in pin 1 to fill with solder to reattach J6955 . Got scared cause I think I went too deep and stopped, LOL. Gonna have to run a couple wires after that one. I think I was going to have to anyway. However! ... pp3v42 is back, and I have no idea how. Any thoughts so...
thanks duke. Top resistor 1.9. Bottom was 4.1. I replaced bottom resistor. Now both resistors at 1.9kohm. G3hot is 19 volts. pp3v43 still missing. Does j6955 have to be on board to get pp3v42? PP3v42 was present before I removed it. Thanks.
Hello. got this in for not charging battery. It sees it and shows its connected but light on charger never turns amber and system report states that it is not charging. If I unplug machine will still run. upon checking the board i noticed the around the BIL connector there was liquid damage. Pin...
2010 A1286 came in today for overheating/shutting down issues. Everything worked fine (Booted into OS full video and backlight, chime.) except for the overheating when it was dropped off in queue. A couple hours later when I turned it on it would only boot video but no backlight. At this time...
Thanks for the response. Though I am definitely interested in doing BGA rework in the future if there is money in it and it becomes more demanding for me I will take your advice and practice with my hot air station. (crawl before you walk type thing)Thanks again Duke. Have a good one.
PS. $1000...
OK... I'll Pray around... Just a few questions first...
1. This is most likely not something I can do with a hot air station. Is there a decent BGA rework station available that you can recommend to carry this out?
2. The chips I'm finding online are from China and cost 11 bucks. Are these...
