you don't need to find out manual for jumper setting any where if you see the mother board very closely near which Jumper want to setup you can see the printed jumper setting on mother board only,
remove the bios battery for arounf 30 minutes to an hour. if you can locte the bios jumper, just turn the PC on the , unplug the jumper then the pc off, put the jumper back and you are good to go on the next reboot.
You will probably need to 'default' the mainboard. There should be a 'jumper' (set of 3 pins with a small cap spanning two of them) may say CLR or similar in silkscreen on the board next to the jumpers. Definitely get a manual for your computer to help you find this jumper - hopefully it will be as simple as moving the cap to the third pin (move from pins 1 and 2 to pins 2 and 3) This will short the CMOS and clear it. If everything else is default settings - then you are good to go. Move the jumper back to original position and try to start.
Did you swap the Cmos jumpers from 1-2 to 2-3 to clear Cmos before replacing battery and if so, did you return them to their original position (normal as opposed to clear cmos)? If the jumper is still in the clear Cmos position, the board will not boot.
Try changing the Cmos battery, it may appear to work but may not be suited to the board
Disconnect all drives except the hard drive, unplug usb and sound cables, if fitted, remove graphics card and either test with another one or use the onboard graphics.
For the chassis intrusion circuit to work, the chassis power supply must be connected to AC power. By default, on the motherboard the pin labeled chassis "signal" and "ground" are shorted with a jumper cap. You need to remove the jumper caps if you intend to use the chassis intrusion
hope this helps
From what I can gather, you just need to locate the jumper labeled PSWD and remove it. Turn computer back on, then back off. Replace jumper pin and turn computer back on. That should do it. Removing the jumper disables password. Turning on computer resets it. Replacing jumper re-enables password capability.
If you're replacing a motherboard then the new motherboard has a jumper across the on/off jumpers. If this is used board then check to make sure the on/off jumper pins are not shorted. If OK boot up and go into BIOS. Make sure that any line stating Automatic Turn ON is off.
reset you bois, open the case, remove the battery, make sure the cmos jumper is set to clr cmos, the start up the pc, putt it off, then on again, then remove the power, put on to remove all power, the replace the battery, and the jumper, then the power cord then power on again
push delete or f2 to go into the bois setup screen then select save, and exit
Dont know why But try resetting BIOS 1) remove M/board battery for 1 to 2 hours refit and see if bios is back in default mode 2) on M/board will be a 2 or 3 pin reset jumper switch with word on M/board reset bios or similar On a 2 pin remove the jumper from 1 pin and fit it over both for 3 or 4 seconds then replace back to where it was and reboot On a 3 pin remove jumper from the 2 pins it is on and fit over middle pin and the one it was not on same time then refit back to how it was and reboot Your computer should now start and allow you into BIOS
Basically your bios need resetting or clearing there are 2 ways, you can use your main board manual to locate the jumper as descrobed below or if you cant find it or that fails then proceeed to the other method described.
.) Find the Jcmos or Jp1 or JBAT jumper located on the board. Its a 3 pin jumper currently set to 1 and 2,,, set it to 2 and 4 wait a few then set it back to 1 and 2.
If you cant find the jumper or that fails then
Locate the battery on the main board
unplug the system then remove the battery and the memory(rams)
press and hold the power button for 3 seconds
replace the battery then the memory (rams)
pulg in the system and turn it on, it should boot
load the optimised defaults by entering setup , follow the on screen instructions to do this
