Re: Asus Ux303UB, Battery not detected after mb change

ok, i guess its not the right part,

what im wondering is, that i cant find another SMB0_DAT and SMB0_CLK besides on this litte ic next to the battery

EDIT
omg i made it!

i found out, that SMB0_DAT wasnt routing to the ic on the other side, while SMB0_CLK...

Re: Asus Ux303UB, Battery not detected after mb change

Yes, its the data line from the battery connector.

I removed the battery and measured again with only the ac plug.

Clk gives me again 3.3. data went to 1.3

Do you mean this little part, marked in orange?...

Re: Asus Ux303UB, Battery not detected after mb change

Thanks for your help so far!

i attached the battery and measured the pins at the connector and the ic

measurements i get just with battery:

connector:

Vpin: 11,5v
Dat_Clk: 3.25v
Dat_Bat:0.1v

Mosfet near battery connector:
Source: 11.5
Gate: 17.3
Drain: 11.6

if i connect the ac with battery still connected i get following readings:

Vpin: 11,5v
Dat_Clk: 3.25v
Dat_Bat:0.1v...

Re: Asus Ux303UB, Battery not detected after mb change

okay, ill test it tomorrow. im at work right now

Will laptop start with battery even if data/clk (yellow and white) are not connected right? it was my first guess, since the pads were missing and i just connected them to the right pins of the ic, the pin was going to.

Hello Guys,

my asus laptop ux303ub stoppped working. I guess the mainboard had a cap / mosfet problem, but i couldnt fix it. It stopped to charge and no power with cable or battery.

I bought it, soldered the connector from my board in and installed win10 again.

so far so good, but the laptop isnt recognizing my battery correct. It stays on, but doesnt show a percentage or something and laptop gets very slow without ac plug.

I...

Re: LG 50PA6500 power supply Relais klicks

Hello guys,

I got the broken plasma LG from ma friend to take a look at.

The tv cant start. If i plug in the cable i can hear the relais klicking several times. It tries to start and klicks again after a few seconds. No picture.

Removed the above right connector. Still the same error.
I found out, that its a power supply Problem.

I measured a few things with the multimeter. Did also a few tests with m_on and rl_on connected to the stby pins like described here.
