[lordgeny]

It worked regularly, I updated the bios and it went ok, even the restart. after i replaced the nvme unit and disconnected and reconnected battery .. total dead . I already tried to flash bios and ec rom ... nothing

Re: Asus P5440F dead

You replaced the nvme while battery was connected?? Start with measuring resistance on all coils.

some caps in short

Re: Asus P5440F dead

Use the lowest resistance scale on your meter and measure again. It appears you are measuring in the Kohms scale so low readings will be 0 ohms.

thats it

Re: Asus P5440F dead

You were asked for resistance measurement and have shared voltages instead.

Re: Asus P5440F dead

Hi guys i have this PC that after a bad battery replacement (broken traces on battery connector) have the IC called C34AH taking 70mA and with 2 legs shorted to ground (assuming pin 2 is GND looking at other ASUS board with diofferente layouts but same chip)

the laptop is not powering on... i think that 11.5V come to this IC (data signals) burning it, anyone have an idea about the name?

very thank you!

(right now i can't remove IC because customer don't want the motherboard "touched".. not yet for warranty purposes)

Re: Asus P5440F dead

Hi, @Bartoloni the C34AH is from Amazing Microelectronic Corp. it is a low capacitance ESD protection array. I couldn't find the same chip, but an equivalent might be an AZC099-04S. I hope this will help you.

Re: Asus P5440F dead

thank you Jarotech ...i have a C34SH from a similar ASUS board (same place near the battery connector) probably the same

Re: Asus P5440F dead

C34 is the device code, S is the date code and H is the control code, so it is the same chip.
If you look at the datasheet for the AZC099-04S, you will know the input and output of that chip.
