A1466 - 820-00165-A very slow

[hgoncalves]

Hi,

I have an A1466 - 820-00165-A that only powers on, if the power on button is pressed for about 10 seconds, and when it boots it is very slow in OS.

Don't know what can be causing this.

Can you help?

AVREF_SMC is OK?

 

[hgoncalves]

No.

PP3V3_S5_AVREF_SMC has 0.035V. U5110 problem?

Or some corroded filter capacitor...

 

[hgoncalves]

It was a bad cap.

TKS!

Hi, again.

It seams that I have another problem with this one: It doesn't recognize any battery. Already tried a know good battery and with same problem. It isen't recognized in the OS, neither by the board (doesn't charge).

Can you help?

Check voltage and diode mode to ground on SCL/SDA lines of battery bus.
What is the exact PPBUS_G3H voltage?

Did you try known good LIO board?

It was a bad contact on the battery conector.

TKS
