The mouse turned off, keyboard was replaced by a new Logitech K208e. Motherboard still disabled when loading, the last value on dr.debug-b4. When the motherboard is switched off, the reset and power buttons remain lit. To restart the motherboard requires disconnecting the power supply from the mains 220V.
The motherboard was handed over to the service center. Edited by Alexander_An - 01 Apr 2018 at 5:02pm |
