passwords, is powered by the onboard button cell battery. Erase the RTC RAM:
1.
Turn OFF the computer and unplug the power cord.
2. Remove the battery.
3. Change the jumper from “normal” to “clear CMOS” for a few seconds
then replace the jumper cap to the “normal” position.
4. Re-install the battery.
5. Plug the power cord and turn ON the computer.

6) USB Device Wake-up (USB01PWR / USB23PWR / USB45PWR)
Set these jumpers to +5V to allow wake up from the S1 sleep state (CPU stopped;
RAM refreshed; system running in low power mode). The default setting for
the three jumpers is [1-2] to select +5V, since not all computers have the
appropriate power supply.
NOTE: This feature requires an ATX power supply that can supply at least 2A
on the +5VSB lead when these jumpers are set to +5VSB. Otherwise, the system
does not power up. The total current consumed must NOT exceed the power
supply capability (+5VSB) for normal working conditions or in sleep mode.
