MSI H410I PRO WIFI - bios mod, disable overcurrent protection
Hello,
Could someone disable USB over-current protection in this bios? Message is displayed over display-port: "Over Current Have Been Detected On Your USB Device!! System will shutdown after 15 seconds to protect your mainboard!!"
Attached dump to this post.
Diagnosed and come to a conclusion that PCH is faulty, there are overcurrent voltage dividers (net names OC#0 to OC#7) on USB power lines, dividers output is nearly 0V, PCH is pulling some of them down. Dividers resistors values are ok and data lines and VCC are not shorted.
Thank... -
Do you think that manufacturer fixed the bug/workaround with latest bios version?
I have backed up original bios v1.26 before updating to v1.35.
Could you please turn v1.26 bios into manufacturing mode as-well?...Leave a comment:

Did not work
Reinstalled windows and seems like Absolute still present, asks for company account.
Reflashed bios, 1st boot, pressed F2, wrote service tag, disabled permanently Absolute, save (Apply changes), restart. 2nd boot pressed Alt+F to exit manufacturing mode then reinstalled windows. Tried this several times, though i did something wrong.
Any suggestions?Leave a comment:

Measured all BQ25700 pins, everything seems quite identical, compared with working board, attached picture with measurements.Only 3 different readings, VSYS, BATDRV# and SRP/SRN.
Tried swapping BQ25700 - same result.
No idea where to go, im randomly swapping components.Leave a comment:

T480 with GeForce MX150 - not charging, no reaction to power button
Hello,
MEC1653-BA1 pulled VCC3M down to 60ohm, replaced it, programmed with vertyanov, no reaction to on/off button and not charging now.
Noticed that VSYS_OUT is 9.18V, had a opportunity to compare on UMA T480, it was 10.2V, no ideas if DGPU T480 should have same VSYS_OUT. -
