I flashed both BIOS & EC chips and I got the following readings (check attachment).

Re: DA0AX1MB6H1 (HP G62-358CA) - Does not turn on & Adapter Led light off when plugge
Hello, this board is Rev H, in the schematic you linked me to, the DC CN is 16, the board I'm working with is CN17.
The reading of PU6 (ISL6251A, it's only 24 pins) are:
1: 5V
3: 1.18V
4: 4.5V
6: 0V
7: 0V
14: 0V
19: 0V
27: does not exist
While testing PU6, parts around were getting hot, should I keep testing it and trace the touch?
I can't find PL11 and PL1, but I think they are the inductors I tested previously. Any ideas guys?Last edited by orientalsniper; 01-19-2014, 11:52 AM.

Is it normal I'm getting 28V in a capacitor (PC69)? Close to PU2 which is a G5933, not a RT8209A, according to the old revision schematic.
Every other resistor and capacitor voltages close to PU2 are jumping.
EDIT: After replugging DC cord, PC69 still gets 28V, and the rest close to PU2 are reading steady 19V, no longer jumping.Last edited by orientalsniper; 01-19-2014, 11:25 AM.

Hello guy, thanks for the assistance, I don't have any readings (0V) in RT8206B or the pins connectors in the battery terminal.
Edit: Also, bluestone, you should try reflashing BIOS and EC, some people reported they got it working.

Originally posted by bluestone View Posthow can i reflash the bios without machine powering on, I have tried swapping bios chips from working ones but still no success.

Originally posted by whaldsz View PostIf you dont get any voltages at RT8206B, then focus your attention to ISL6251A pin 1, 2, 3, 8, 15, 24.
2: Jumping up to 0.5V
3: Jumping up to 1V
8: 2.3V
15: 5V
24:Jumping up to 18V
Can you please tell me how do you know which pins to test?Last edited by orientalsniper; 01-21-2014, 09:28 AM.
