Hello. I have a problem with an Asus FX506L, motherboard DABKXDMB8F0 rev.F. It arrived dead to me, and after changing the Bq 24781 the 19V rail appeared. Then I discovered that the EC chip IT8987VG is shorted. I took a chip from an HP laptop and after soldering it, the sources were activated and 3.3V, 5V and 1.05V appeared, and 1.2V oscillated, and the problem here was with a mosfet with a short between GS. Now the voltage is ok, but the laptop does not start, probably because the EC chip has an Hp bin instead of the one for Asus. I understood that this EC chip IT8987VG self-programs itself, but...

Heloo . I need EC bin for Acer aspire 3

Model no: N20C5
A315-58-53LB
FH5AT LA-K093P rev.1.C

I can t see serial number.
thanks in advance here's my back up...

Now the laptop doesn't want to start at all. The current drawn by the board is 10-20mA but sometimes 130mA. I noticed a strange problem with the PUZ1 integrated circuit. It has voltages on pins 10 and 29 = 5V, on pin 22 = 19V, but on pins 23 I have 0.1V but also 5.9V, on pin 24 I have 0V but also 1.7V or 4V, and on pin 12 I have 0v or 0.6V. These voltages change if I put a drop of isopropyl alcohol on the PUZ1 integrated circuit (RT3612). Before ordering the RT3612 I said I would try to program the EC chip and I would need a bin. I am also attaching the original bin. The serial number is no longer...

Only with power adapter the unit stay on, and after few seconds the laptop displayed Critical low battery and then off. I can't measure the voltages right now because I'm not at home, but I'll be there in 2 hours and I'll post.Thank you very much for wanting to help me.

With the battery disconnected and only the charger plugged in the laptop it show Critical low battery. I measured the voltage on Bq chip and look good, i even change it.

It s the same motherboard. I did this, I have 2.9v on the ACDET pin. Now the laptop starts completely, I have all the voltages but it shows Critical low battery on the display,and than off. If I inject voltage into the battery it doesn't charge

Hello. I had the same problem with the DC jack, but the laptop still did not work. Now it turns on, but it shows Critically low battery and then turns off. The battery is completely discharged. There is also a BIOS reset button, but even though I tried, I still can't get rid of that message. The battery measured in the BIOS shows 3V. Where could the problem be? Thanks.
