    Hey!

    I would not bother with jumpers. When you find the circular CMOS battery, remove it for at least 15 min to be on the safe side.
    Be sure to disconnect the main power battery or this will not work.
    Replace the battery and power battery and boot.

    Good Luck!!

    the battery might not be disk shape but clyinder shape like 2 AAA batteries in line. if cylinder shape gently disconnect power wires from motherboard connector(usually white) & wait 15 or so minutes like ianski7 said. the other possibilty is battery is soldered to circuit board

    Hey Sirenia!

    It's been a long time since I took one of these apart so I can't remember very clearly. You may have to remove some other plates and pieces to get to the battery. Keep the screws seperate and replace them from where they came.
    i can't find the schematics of the motherboard so you'll have to poke around.

    of course it is not same laptop, there is 2 generations between a p1 computer & a p3 computer as in the link so design has changed. does the keyboard move side to side slightly?

    Hey!

    Sorry, your LT is seriouly old and that is the best I can do.You'll have to earn the pat on the back!
    Look very closely at the part you want to remove and locate where it is or could be fixed by screws.

    Hey!

    I too came across the EEPROM thing but the LT that I worked on abot 3 years ago had a battery-- I was hoping it would be the same. The EEPROM thing could possibly fry the chip. I also came accross a company that replaces them for about 100us.

    We'll see how it turns out.

    ianski7, what do you think they use on regular motherboards. besides instead of using a paperclip a jumper is put on the motherboard & we just have to move it when we want to clear the cmos chip

    Hey!

    Then how do you explain the diclaimer!

    Don't get me wrong, I have jumped machines to start,clear CMOS,IDE configuration problems....
    I just prefer the ways the engineers gave us.

    Your not going to compare a shielded jumper to a paperclip held by a human generating an electrical field are you!

    the jumper is not shielded, it is just a piece of shaped copper wrapped by molded plastic that makes it easier to handle thats all. the disclaimer is just in case you touch wrong pins by mistake & fry the chip & go after them. i worked for almost 4 1/2 years at celestica doing board work on sun microsystems, cisco systems, nokia phones & others so yes i know what i am talking about

    Hey!

    The plastic is to shield it from YOU! When you worked on boards were you grounded? I bet you were! I am not going to give you my resume but I will give you this:
    The purpose of this forum is to HELP people so let's get off our soap boxes and do just that!

    ianski7, the plastic is there to make it easier for a person to extract that jumper whether by fingers, pliers, tweezers, dental tools or whatever. i am not on a soap box i am sitting in my chair stating a fact & whatever works for an individual might work for others. teach & learn that is why we are here for

    You are suppose to be helping not saying i know more then you.

    You are both right. It does shield the copper and it does make it eaiser to put it on and remove the jumper when making the temporary circuit.
