Hi I am getting warning message :The AC adapter type cannot be determined.
This will prevent optimal system performance.
Please check the AC adapter connect properly, remove AC adapter and plug-in it again
So this appears whenever I plug my charger with some power socket but when I plug with different power Socket the message did not appear and also running diagnostic did not report any charger problem warning
Messages so please let know how to identify which power socket we have to use for plugging charger?
There is only one power socket on the system.
Does the system setup (F2 at powerup) recognize the AC adapter, or does it show unknown?
I'd guess wherever you do see the problem, you have a wall outlet that's not correctly grounded. If these are in your home, have a qualified electrician check the outlet.
If it's a sporadic problem with many outlets, I'd guess it's either a charger with a bent or misaligned center pin (carefully straighten that or replace the adapter) -- or a DC jack in the system that's going bad. That's this part:
