Acer q5wvh

[vektro]

Hello,
i have an ACER Q5WVH of E1 series. It cant turn on(with and without battery) while i press power on/off button it turns on for a second(fan spins and power LED lights) and then turns off. If i try to charge it, charging LED(orange) lights normal for 5 seconds and then power(blue) LED and charging(orange) LED start blinking. My battery is full charged.
Here is my motherboard schematic

My power IC is BQ25a (https://cdn.badcaps-static.com/pdfs/...9485119ff4.pdf).
I am not sure how to check it.
Any ideas or help is accepted.

Hello, everything indicates that your card has two BIOSes, U36 and U42, but as U42 is in the scheme with @ I think it should not exist on your card, so I would backup the U36 and start rewriting that chip.

ridamouh159 thank you for your upload.
i reprogrammed both chips and the problem persists...
but the first time i tried to power on it, the power led and fan stayed on for 5-6 seconds and now stays on for a second as before.

any suggestion for the next step??
