Checking this laptop, coffee damaged, 5V to HDD missing, and coolers won't spin at all, need to follow the path to voltages. Hope it is available, thanks in advance.

Re: Asus UX303U schematic
After cleaning up all the mess, a very tiny 100k resistor at PR8823 was missing, and it feeded the gate of the 5V mosfet at PQ8801, so that was the fault.
@SMDFlea Thank you thank you thank you very much!!!

Re: Asus UX303U schematic
Hello PinGuy,
Did you manage to find a schematic for this MB? I have been unable to find one. Couldn't open the boardview file either using the latest version of the Fritzing program; I'm getting the following error:
I'll contact Fritzing tomorrow to pursue that but would appreciate any leads on a schematic if anyone has any.Parse error (1) at line 1, column 1:
error occurred while parsing element
D:\WPDOCS\Business\Laptop Boardview Software and
Boardviews\UX303UB_2.0_60NB08U0-MB1410.fz
I stupidly neglected to disconnect the battery before disconnecting and reconnecting the LVDS cable so blew something. <Sigh>Comment

Re: Asus UX303U schematic
Thanks @mon2! My Av quarantines that but I'll try to make an exception. Any suggestions re. schematic?

Re: Asus UX303U schematic
You can use openboardview as well, with the fz license key added. https://openboardview.org/

ASUS STRIX G531GT MISSING PM_SLP_SUS#
Hello guys i have ASUS laptop that power on but can't switch ons , i trying using power sequence and last missing PM_SLP_SUS# .
here what i measure already:
EC_RST# 3.3V
SRTCRST# 3v
+3VA_RTC 3V
RTCRST# 3V
ME_SusPwrDnAck 0V
AC_PRESENT 3.3 V

PS_ON 3,3V
+3VA_DSW 3.3V
DPWROK_EC /R 3.2V
PM_BATLOW# 3.3V
SM_INTRUDER# 2.8V
PM_SLP_SUS# -----> MISSING VOLTAGE ( but sometime this voltage is present )
THat is can confirm PCH relate issue...05-28-2024, 01:30 AM -
Hey guys.
Need help with this one.
Fan not spinning due to missing PWN Fan signal.
Also 5 seconds from powering up it freezes, unless in BIOS.
But as soon as Windows starts to load, it will freeze.
CPU is COLD / Room temp when it freezes.
I've replaced the CPU, same problem.
Replaced SIO/KBC IT8987e and reprogrammed - same problem.
Replaced fan - same problem.
Replaced flex cable from board to daughterboard (which has fan connector on it) - same problem.
Checked the Thermal sensors around CPU and Board to the SIO/KBC and...08-19-2024, 05:22 PM -
Hello,
i'm looking for a schematic/boardview for an ASUS E3-PRO V5 (NOT E3 PRO GAMING, has a different layout).
I'm trying to find out where i can find SKTOCC# other than from the socket in order to ground it for a Coffee Lake mod. It must be somewhere near/around the SIO but I haven't found a datasheet for the NCT5539D this board has.
I've also found the schematic for the similarly named E3 PRO GAMING V5 but it has a different SIO so it's not of much help. And I don't trust myself to hold still a multimeter probe on top of a LGA socket pin to find where it comes out the...01-18-2025, 09:17 AM -

"Hello friends. My Asus X556U laptop is not charging, not turning on, etc. I wanted to repair the motherboard, partly for learning purposes. One of the capacitors is giving a 24V output, and one of the MOSFET pins is also giving a 24V output, and honestly, this surprises me. I think I need to replace the capacitor, but I don’t know the capacitance value. I tried searching for a motherboard schematic but couldn’t find anything. Can you help me find the schematic or diagram?"
