A1502 2015

[MDY]

Have not schematic and boardview for this model. Also dont know what 820-xxxx model is. It is not 4924

With connected battery and ac adapter power itself and chime every 18 seg. Mouse is on. Screen is cracked, so I cannot see if there are image. I tried also with disconnected screen.

you should have a displayport/usb to dvi/hdmi adapter for testing, they are like $10 on ebay

Yes, I have. But this is not my problem. If it chimes each 18 seg, this menas it reboot each 18 seg. Also need schematic and boardview to check. If somebody can upload them.

laptop-schematic.com . if you do this fulltime it might be worth spending the $250 usd and getting all of them, i think you can get everything up to 2015, or they are $20 each, check the board for corrosion or wait for duke to answer you

we do not share or upload schematics here. that aside this request would be impossible without the board model number.

If you unplug the internal display it should default to hdmi out so you can at least see what it is saying when you try to boot into an OS. What do you see?

Still restarts if SSD is removed?

 

[MDY]

Tomorrow will test. Any idea what 820-xxxx number could be? This is A1502 2015 model.
