Sorry I don't have an oscilloscope.

Yes proper charger yes I know about the fan not spinning until cpu warms up you didn?t answer my questions in my last post?? Well? I need you super skills of deduction :)

Should there be pulses on SCL/SDA or should it be a constant voltage and if constant what voltage should I expect to see? 3.43? Also were the diode measurements I gave you a good sign or bad sign? If we put the battery aside for now why do you think I don't get fan spin with no battery and just...

SCL and SDA seem to be jumping around within the range 3.43 to 3.33 V. So I get 3.43 one second then 3.33 / 3.39 /3.34 /3.41 etc These readings are without battery. SCL 0.499 V Diode Mode SDA 0.497 V Dode Mode I'm sorry but I don't have another board. Thnx M

ISL6259 Pin 9 = .035 V Pin 15 = .067 V Resistance between pins 17/18 = 3.8 Ohms Resistance between pins 27/28 = 20.5 Ohms PPBUS_G3H = 12.56 V (Without battery) PPBUS_G3H = 13.01 V (With Battery) Don't have a good battery to try. Thnx

It?s a genuine charger. It shows the charging icon but doesn?t appear to charge - but keeps the battery at 68%. Kept it plugged in and the battery level didn?t increase nor decrease

OK so here is the current situation. Screen is working it was just a bad cable. Here is what is happening so far.... If the battery is plugged in and I plugin the charger, MacBook Powers up. If the battery is not plugged in and I plug in the charger it will NOT powerup.(even when pressing the...

Is it possible to get hold of MRI for a MacBook Pro Retina Early 2015?

Ok will try and see what happens many thanks M

Another question if I may? If the logic board is working fine and I plug in an external display but disconnect the LVDS cable should I get a picture on the external monitor? Thnx M

mmmm I see. I'll have a quick look on youtube regarding changing the LVDS cable. I hope it's not a nightmare to do! On a separate question - Why would the machine only power on when both magsafe and battery are attached?

How can I check to see if I always have backlight? It's black screen - no video no backlight as shining a torch shows nothing. Have checked the LCD connector and the plastic that separates pin1 (PPVCOUT_S0_LCDBKLT) from the back of that cable seems damaged. I'm attaching a picture of the end of...

OK so the MagSafe 2 charger arrived earlier today but I'm still getting the same problem. If I plug the battery in and the MagSafe the MacBook loads fine. Well I say fine - sometimes you hear the chime and get display and other times you only hear the chime and get NO display (I don't mean no...

Lol Yes that?s what I meant to say

I've ordered an OEM magsafe 2 adapter. Should be here soon. I'll get back to you once it arrives. thnx. M
