Re: Acer a715 GTX 1050 not detect
I did some measurements so I would beg for help
I found that I missed him VGA CORE and my further testing was
+VGA_CORE shorted (Pc1771 pc1772 pc1773 etc)
When I turn on the laptop, voltage appears to +VGA_CORE 0.9v
Resistance +VGA_CORE and ground 2 Ω
Resistance 19B+(ADPIN) to +VGA_CORE 475 MΩ
My power supply measures a consumption of 3 mvLast edited by zvonko72; 09-24-2021, 06:12 AM.Leave a comment:

Re: Macbook pro problem with heating some parts
Thanks for the reply.
I took out the motherboard, removed all the connectors and cleaned with alcohol. I didn't see any problem with the displayport. Maybe I needed to check something else, voltage or some resistance or maybe...Leave a comment:
