ROG G752 USB port overheat

last update: 23/06/2017

The Problem

From time to time, I noted that my ROG G752VT heated horribly in this point (above the right-bottom angle):

After some investigations and tests, it seems something related to the quick charge capability of the nearest USB ports.

Since I don’t need it, I tried to switch off by some BIOS/OS setting, but I didn’t find one.

The only way to switch off this feature seems to be the handled by USB Charger Plus program.

The main problem here is that you can only set the trigger only to 99%.

This allows to switch off quick charge when the battery hits 99% of its change status. It works badly when you plugged the notebook keeping the charge to 100%.

My first workaround

I found how to set manually the threshold to 100%.

  • Quit/terminate USB Charger Plus program by using the Task Manager.
  • Open the notepad with Administrator privileges
  • Load the following file:
C:\ProgramData\USBChargerPlus\AsACP.ini
  • Change the value to 100 and save the file.
  • Logoff and logon again (to restart USB Charger Plus).

As you can verify from:

C:\ProgramData\USBChargerPlus\AsACPLog.log

The program has taken the new threshold value.

Up to now, I still had limited overheat episodes.

The actual workaround

I removed any unnecessary package, including:

  • USB Charger Plus
  • GameFirst packages

In addition, I had suspended AsIO.sys driver.
To accomplish the task, I used MS Autoruns.

Run it with administrative rights and:

  • select ‘drivers’ tab
  • locate ‘AsIO.sys‘ entry.
  • uncheck or delete it.

Up to now (a week has passed), no overheat episode has been occurred.
