qal70 la-7741p
Can anyone help me out with the schematic/boardview for this? I have a laptop that will not POST (POST card shows nothing). I was thinking of reflowing the GPU & CPU, but I'd rather try and check out the power rails. Also open to suggestions or any sort of help. Thanks. all of you rock! -

Re: Asus Zenbook UX330UA odd power issue
Also, you're saying it might be a mosfet that is looking for a signal from the battery before letting the signal from the power button come through (or something of the sort (a "p" or "n" mosfet that relies on the battery signal))?Leave a comment:

Re: Asus Zenbook UX330UA odd power issue
How do I test a laptop battery? And could the battery still be the culprit if the laptop stays on without the adapter, after being powered on by connecting it (without hitting the power button)?Last edited by ElJap0; 05-25-2019, 03:47 PM.

Re: Asus Zenbook UX330UA odd power issue
Could you clarify how this would help to troubleshoot (no sarcasm intended). The power button not triggering the P.O.S.T. with a charged battery would lead me to think something is wrong with an S5 rail. That maybe the keyboard (or something else) is not being supplied power. Your input is appreciated, but could you clarify your thoughts on why a bad battery would be the culprit (again, no sarcasm intended)Leave a comment:

Re: Asus Zenbook UX330UA odd power issue
Battery is fine. It holds a charge and charges properly when I boot into an OS. But the weird thing is that it boots automatically when the chrager is plugged in (similar to a MB Mobo externally with an 85w adapter), and once in the OS the power button functions. But if you leave the adapter out (with a fully charged battery) and try to turn it on with the power button, it does nothingLeave a comment:

Re: Asus Zenbook UX330UA odd power issue
I don't see a cmos, and there are a few IC's that look like they can be the BIOS. Should I just hit pin 1 on anything that looks like a BIOS chip? Also, there is no CMOS on the IO boardLeave a comment:

Asus Zenbook UX330UA odd power issue
The power button does not turn the machine on. But when the adapter is plugged in, it will boot properly (without pusshing the power button). When in the OS, the power button responds. Can anyone shed some light on this or provide a schematic or boardview? -
