Hi all, I am working on ASUS model TP401M (MotherBoard Part # TP401MAR R2.0). The motherboard is totally dead. I am getting the 19 volts on the motherboard but am not getting the 3.3v & 5V. All chip on the board have customized numbers. Does anyone know what are the real IDs of these chips. 1. 65=7E B1R (28 pins, two of these present on the MB) 2. 2N=7E KBX (20-pin). Requesting if someone can share the Schematic or boardview for this model, I would appreciate. Thanks in advance.

Re: Schematic or Boardview request for ASUS TP401M
Parts with an = will almost certainly be Richtek parts - https://www.badcaps.net/forum/showthread.php?t=90619

2N= RT8249CGQW https://cdn.badcaps-static.com/pdfs/...d7b1efab2b.pdf
65= ATK1602AGQW ,no datasheet.There`s 2 of those in the X507MA boardview - https://www.badcaps.net/forum/showthread.php?t=94822 .No TP401MAR boardview available yet afaik .
I think the RT3601EA (Marking 3H= ) is the equivalent Richtek part number,there`s 2 different Typical Application Layout Circuits in the datasheet ,using embedded mosfet drivers (X507MA) ,or using external mosfets .Check the pins to make sure which layout yours has.

Re: Schematic or Boardview request for ASUS TP401M
You are so very right "SMDFlea" about this board using embedded mosfets, the TP401MAR also has two MOSFET, but one show 0 ohm, remove it but still zero ohms, No idea why is this. There is a current resistor 1ohms next to it, removed it but the reading still show 0 ohms., I injected 1.2 volts to find any short but nothing is getting hot. At least you have given me the reference of X507MA Boardview. I will surely look into it today. Thank you very much for your help.Comment

Hi, I am also working on the Asus TP401M but the backlight is busted. Can anyone provide where it is located? The computer turns on and I can see the display but it is very dim I want to see if it is the backlight on the board or the screen. Thanks.Comment

Hello!
I need schematic & boardview for Asus ROG GU603ZI-NEBULA010, mainly around the BIOS (W25Q256JVEN), because there are missing approx. two resistors or capacitors.
Thank you!...11-17-2024, 03:02 AM -

Hello, I have problems with an Asus Vivobook M513U. Laptop is working fine on battery, but the battery is not charging and also the laptop is not working with the power adapter, despite the orange light on the side is lighting up and it says the laptop is plugged in (but it does not say if it's charging or not).
I was told, the owner has just installed a new SSD before the problem appeared, so I suppose something was shorted out while he removed the battery. The BQ chip might be dead, but I need to check further, so I need the schematic and/or boardview of this model. -
If anyone has the boardview and can share I would greatly appreciate it! I have the repair guide, but I still need the boardview. My BMC cannot initialize, likely due to damage around the enable switch....
