Subject: J4105 boot problem
Posted: 05 Jul 2020 at 12:33am
My J4105 (fw 1.40) has a strange behaviour at the boot.
The first time I boot after a prolonged poweroff time, the board shutdowns before the beep and just before "Press F2.... etc".
If I press the power button again, everything is fine.
If I reboot from inside the os (Win10-64), everything is fine.
If I shutdown the system, disconnect the power cord for a couple of minutes, connect it again and then power on the board, everything is fine.
But if that pause becomes 10 minutes, the problem appears again.
I suspected a psu related problem, so I tested with another psu, no results.
I made a ClearCMOS, no fix.
It seems as a capacitor need to be charged first, but the board is new and there's no cap with evident signs of failure.
Any idea?
