Direkt-Tek 11.6" almost dead.

[Francisco.s]

Hi, have a Direkt-Tek 11.6" with a y116c rev 5.1 motherboard that is almost dead.

There is a blue led that lights-up and there are good pulses in bios chip, but pulses last only one second and stops.

There's no more activity and power button does nothing.

It have some voltages on PMIC chip AXP288, but without schematic is a nightmare.

There are no valid bios dump for download, only found one in this tread: https://www.badcaps.net/forum/showth...ighlight=Y116C
but seems not to be for same model.

With AMIBCP reading original dump I can get this:

With AMIBCP reading dowloaded dump I can get this:

As you can see there are a mismatch with model code.

Can someone share a good dump for this model?

Some help with the circuit will be gratefully appreciate.

Here it is the original dump:

This is a low resolution photo of the "motherboard".

You can see a pen mark on the keyboard connector. This mark points to a pin that is connected to ground, and besides it there is one pin that has no voltage, but I think it is the power button signal.

I will investigate why there is no voltage in this pin, but without keyboard connected still has no voltage and there's no short also in that pin.

I will post all results.

I can confirm that this pin is connected to power pin of APX288.

but without keyboard connected still has no voltage and there's no short also in that pin.

There no short to ground, but it has a low ohm reading to ground. (350 ohms)
the APX is not getting hot, but it's clear that this IC is damaged.
