so, its impossible to charge up a battery with DC Powersupply, or I have to find SYS_DETECT_L and then the battery would alow charing on a DC Powersupply?
Now days battery have many sensor lines and + and -.
I have a battery at 0.1v when I plug in it the DC powersupply at its requested voltage. The battery won't draw any Amps and stays at 0 Amp consumption.
How do I make the battery hungry to be charged by a DC powersupply?
Dear Administrator,
I have a board with minor liquid damange.
PPBUS_3GH is present.
F7140 = 8.6
U5110
Pin 1 = 3.42
Pin 2 = 0
Pin 3 = 3.42
Pin 4 = 2.8
Pin 5 = 3.3
Pin 6 = 3.4
Pin 7 = 3.42
Pin 8 = 3.3
Liquid damange I made some foto's looks like DDR Power supply chip is damange. But I dont...
It should protect the board from getting to many current in? Lets say when a wrong battery is attached?
I don't get how the same Q7155 works both ways, for charging and for suppling current when DCIN is disconnected.
Oke, all working now!
It just randomly went on after going deeper.
Is it possible to leave S5_PWRGD out? Or would it make the system very unstable?
With BAT only it won't turn on.
On Q7155 with battery only connected
Pin 5 = 7.8
Pin 1,2,3 = 0
Pin 4 = 0
On Q7155 with battery and Charger connected
Pin 5 = 7.8...
Dear,
No green light.
I'm measuring on Pin 3 a short to ground.
R7110 on the right side:
PPCHGR_DCIN = 16.5
R7110 on the left side
CHCR_ACIN = 0
All other meassures on U7100 seems fine.
Pin 2 = 16.5
Pin 12 = 3.5
I guess I need to replaec my ISL.
right?
Angry teachers is most likely to learn fast.
Keep screaming. I learn twices as fast.
PP3V3_S5 = 3.3
PP3V3_SUS = 0.001
Sorry, i Guess it was not so smart to inject AMPS.
Thanks for reply Amigo:
There is no short to ground on PPBUS_G3H I have a steady 8.59v
C7582 was shorted, I know how to find shorts with my DC power supply. Just to stupid for diode mode. Hope to learn from you.
C7582 was burning on my FLIR camera on 4amps 1v. I removed and the short was gone...
Dear,
I try to read from other Threads, but I see to get stuck.
C7582 was short. Removed and replaced. After that laptop worked fine. But after 10 seconds the same Talanoium Capacitor was short again.
Now I removed C7582 and there is no fan spin no boot.
The light charger is red without...
