Is it ok to remove the rtc (cmos) battery from my laptop without replacing it?

Since that battery ALSO controls the memory for the BIOS settings, your "boot" problem was probably an incorrect setting, or a "dying" battery that allowed some of the BIOS memory to become "corrupted" through insufficient power.\n\nWithout the battery, your time and date are not correct, AND your BIOS boots from the factory "default" settings.  Some programs REQUIRE at least the DATE to function correctly such as your scheduler, some updaters, etc.\n\nI would recommend replacing the battery.  \nYour BIOS will remain on the "default" settings until they are manually changed, so if it runs fine, you need do nothing to the settings.\nYou should be able to find a replacement at the Wal-mart or Radio Shack, or a local computer store or repair shop.

you know how to change the time, from control pannel, regional settings, then you try the bios battery, change the bios battery. see it helps or not, and dosent matter as the batter is less than rs 15. so get it easily. less than a dollar.

Ok there are two ways to do that.\n1. Remove the CMOS Battery from the motherboard.\nSo you need to open the case and you should see a thin battery,just remove it for 1min and than put it back and bios should now be reset.\n2. Some motherboard has a jumper (pin) to the clear the cmos.\n\nThe removing of the battery works almost all the time. If it doesnt work please update your post with the specific e-machines model you have so I can better help you.

Most computers have a small battery. In many cases, the battery is soldered directly onto the motherboard, but the battery is usually in some sort of holder so it is easy to replace. Computers are not the only things that have a small battery like this -- camcorders and digital cameras often have them, too. Just about any gadget that keeps track of the time will have a battery.\n\nIn your computer (as well as other gadgets), the battery powers a chip called the Real Time Clock (RTC) chip. The RTC is essentially a quartz watch that runs all the time, whether or not the computer has power. The battery powers this clock. When the computer boots up, part of the process is to query the RTC to get the correct time and date. A little quartz clock like this might run for five to seven years off of a small battery. Then it is time to replace the battery.

are you powering up with your battery alone, or are you plugged into an outlet?\n\nhow old is your computer? is it worth spending money to fix it by going to a computer repair shop?  are your files very valuable?

Time to scrap that junk out dude! This is the 21st century! That unit came out just a little after the abacus! Seriously though, you need to replace the cmos battery. Everytime you shut down your bios looses data that would normally be saved. That is what the cmos battery is for.

well if its a ibm thinkpad it should be under a cover on the bottom possibly where the ram slots are. you will see a small yellow disk with a red and black wire coming off plugged into the motherboard. unplug it and twist the disk off it is sticky taped to the mboard. you can the get ripped off and order a plug in replacement or do it the el cheapo way like me and buy a calculator replacement battery it does not have to be the same model number but it does have to be lithium and the same voltage. cut off the heat shrink and cut off the tabs then resolder with the CORRECT voltage + and - wrap it in electric tape then plug back in restart your computer and it should work.

cmos pad? do you mean the shiny battery? open your case and gently push the battery toward the retention spring....it should pop out. it's a 2032 coin cell. when you replace it, make sure you put it back with the flat side up. If you mean the chip, you can't and will need a new motherboard

If you are looking for another way to break the code without having to change it .. then you will have to guess it ..\n\nBut if you want to reset the BIOS clock without removing the battery .. then refer to your mainboard manual and check the right position of the jumper .. usually it is a three pin panel with a jumper hooked up to two pins the instructions says you should power off the machine then fix the jumper on the other two pins (notice that usually the pin in the middle is joint between the three pins) then power it on .. and then off again .. then return the jumper to it's very first position .. then power on the machine .. and you're good to go!

CMOS batteries are quite inexpensive, much cheaper than a new drive.  However, they rarely fail.  When I read the title of your question, I thought jumpers, but it it was working, that's not it.  Most likely the onboard drive controller has failed.

if u forgot it , then u should remove the battery in mother board and tern ur laptop then shout it down put the battery in same place then , it will be rest

No, you can always use parts. Myself I use parts off old computers all the time. Just today I took the cmos battery out of an old computer for my laptop. Also If its not really old you can try and sell it instead of junking it.

most don't have internal power supplies, that is the little box in the cord, some do, and no they can be removed and changed, which laptop do you have

To reset the CMOS on a laptop, you will need to remove the internal CMOS battery. THis is no easy task on a laptop. Try to find a diagram of the model. Laptop batteries look a lot different than Desktop CMOS batteries and they vary in appearance.
