1434444 2017-04-21 11:00:00 Hi guys,

I have an issue with my Macbook Pro mid 2009 . The DC Jack was broken and ordered a new one on trade me, this arrived and I have replaced it using this guide:
. ifixit . com/Guide/embed/1358" target="_blank">www . ifixit . com
Everything went well however, at present, I plugged the magsafe adapter in, and the light went from green to orange . After 20 min (light still orange) I tried to boot it but nothing, no HD sound, no chime, nothing .

Am I too impatient and should I wait until the battery status is green before attempting to turn it on?

It continues to charge, I pressed the bluetooth button which also works

With the power off and charger connected. Orange led should be on the charger.
Press and hold Shift+Ctrl+Alt/Option and while holding those down press the power button. You should see the charger led go green then back to orange.
Release the keys and try power on.

1434446 2017-04-21 21:28:00 Hi CYaBro, it didn't work....do you perhaps think I damaged the logic board when replacing the DC Jack? It seems to be charging.....but not turning on... I have rechecked all the cables last night but everything is as per the instructions of replacing the DC Jack. mark1978 (13845)
1434447 2017-04-21 22:06:00 Its been on charge for several hours now and the orange light remains on..., when pressing the bluetooth light, that lights up fine as well..... the LED on the charger doesn't seem to switch over to green and the battery must be full by now........mmmmmmm....... I don't know anymore......I have tried everything.... mark1978 (13845)
1434448 2017-04-22 02:12:00 Presuming that you replaced a connector which is available to the outside world, always check for broken tracks caused by heavy-handed usage.

Use a multi-meter (ohms) and check continuity from the solder joint you have made to a solder point further along on the track it is soldered to.

It's is almost always broken tracks and not the actual plug/socket which is the problem in the first place, especially if the connection is intermittent and can be connected by wiggling the plug/socket.

Remember to disconnect charged battery before measuring with ohm-meter.

1434449 2017-04-22 12:55:00 What's the Bluetooth light you're talking about? CYaBro (73)
1434450 2017-04-22 22:25:00 the light (and button) by the head phone jack... or is that the battery light?? zqwerty, that goes over my head, I have no idea how to do that :( mark1978 (13845)
1434451 2017-04-22 22:37:00 Its the battery light not Bluetooth light lol....so when I press the button to see the battery status, all led light come up from left to right....the last one flashes a few times then it fades... mark1978 (13845)
1434452 2017-04-22 22:54:00 Am not sure if it's possible to take the battery out and let the macbook start through the magsafe directly? mark1978 (13845)
1434453 2017-04-22 23:11:00 Just tried it....did't work although the magsafe remained green, not amber the MBP did not turn on. I must have damaged something on the logic board when repairing the DC Jack. mark1978 (13845)
