So, i have HP All-in-One - 24-g051ur and i accidently disable All usb ports via bios (usb secure).
Now I cannot enter BIOS because the keyboard does not work. (esc, f10, del, win + b don't work). The operating system is not installed.
I tried to clear the cmos by disconnecting the bios battery for 1-2 minutes. (with pressing the power button for up to 1 minute). After clearing the cmos, when the power cable is connected, the pc starts up immediately and restarts 2-3 times with a black screen. After that I was getting the following picture, it looks like the cmos has been cleared ...
But, after rebooting, the keyboard still does not work.
Also on the motherboard (hawaii-2g) there are 10 pins with one jumper. To clear the cmos, the jumper position is 1-2. But what should I do with it? 1) set a jumper 1-2 pins when the power is off? 2) set the jumper to 1-2 pins and turn on the power for a few seconds, turn off, open pins 1-2, turn on again?
