I made some measurements on the EC chip unsoldered.
All the low resistance is coming from the chip itself.
That would mean the chips are low quality, because the resistances are too low, correct?

Thank you for the reply.
It was soldered properly, and I checked all the pins under microscope if they were solid and no bridges between pins.
I just desoldered the EC chip to check resistances without it (maybe some broken/shorted traces between layers), but everything seems fine.
+3VA_EC - 33ohm > 135kOhm
+3VPLL - 33ohm > 139kOhm
+3VACC - 33ohm > 142kOhm
Pin 43 (KSO7) - 33ohm > OL
Pin 41 (KSO5) - 10ohm > OL
Pin 33 (OP_SD#) - 3.8ohm > OL
This would indicate wrong/defective chips, correct?

ASUS K570U (X570UD) low resistance after EC change
Hi.
I have a ASUS K570U (board model X570UD) which had a bad EC (IT8995E-128 DXS). I ordered 2 new EC chips on AliExpress.
After I changed first chip and powered it on, nothing happened, and I found out that there was a short on +3VA_EC. I desoldered the EC and checked +3VA_EC on board, it had kOhms (cant remember exact number). Then I checked the GND and +3VA_EC on the EC chip itself and they were shorted.
Now, I soldered on the second chip and made measurements on all the pins (I have not powered the board with the new chip yet). And I found these pins... -
HP ProBook 445 G7 no POST only on battery
Hi.
I have a strange problem with HP ProBook 445 G7 (DA0X9MMB8F0 RevF), that there is no POST while only on battery. The Caps Lock blinks 5 times slowly.
When I attach DC Jack, the laptop will charge the battery and switch on.
And now the strange part:
1. While the Windows is still loading, and I will remove the DC Jack, the screen goes blank and the Caps Lock light will start blinking 5 times slowly.
2. When Windows has been loaded and on desktop, when I unplug DC Jack, it will work normally on battery. While still on battery mode I switch the laptop...
