    By both batteries, do you mean main and CMOS, or do you have two main batteries?

Is it asking for a password and did it just start doing this? Please give a little more info to the problem you're trying to fix. Some problems with IBM can be more difficult than others.

On my e-machines t3418 motherboard what pin setting should the jumper be for clear cmos


1. Usually there are 3 pins, and you put the jumper on 2 of them to clear CMOS, then return them to the other 2 for normal function.


2. What you're describing seems more like a dead motherboard battery. Replace it and the computer should hold the time and date.

Forgot the password and cannot start my laptop


Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

Make sure to turn the PC off before opening the cabinet and resetting the jumper



Hope this helps


The most common way that most of us know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing a battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off the battery power, the BIOS/CMOS settings will be erased.

hope this helps

Clear cmos Dell dimension 3000. It don't have pin or jumper


Open the case and locate the CMOS battery. Just nest to it should be a button or jumper. Press the button or remove the jumper, then start the machine.

If it's a jumper, turn the machine off once more and replace the jumper before continuing.

Hi

Check ASROCK P4i45GV R5.0 User Manual Page 17 - http://download.asrock.com/manual/P4i45GV%20R5.0.pdf

Note: Check Page 11 for the CLRCMOS0 location on the motherboard. From the picture CLRCMOS0 is number 18. You can locate CLRCMOS0 just below the CMOS Cell Battery.

Turn off the computer and unplug the power cord, then use a jumper cap to short the pins on CLRCMOS0 for 3 seconds. Please remember to remove the jumper cap after clearing the CMOS. If you need to clear the CMOS when you just finish updating the BIOS, you must boot up the system first, and then shut it down before you do the clear-CMOS action.

Regards
Mike

CLEAR CMOS


First switch off at wall and remove power leads. The push on button to discharge capacitors on board.

 The jumper will be located near the bios battery and chip usually at the bottom right of motherboard. Move the jumper to the clear position and leave for a few mins. Then put back into normal postition and start pc up.

If that fails to clear it then repeat but remove the battery from the motherboard too and wait longer.

Hope that sorts it for you?
