Question about PC Laptops

Hi Conrad, how can I get to my notebook motherboard's battery

Need some help as far as getting my cmos re-set, how can I get on the inside of my notebook emachine M-5312 model. I've already unscrewed the screws on the bottom but can't seem to get it open to see if there's a jumper that I have to re-set, a battery in it. Don't want to force it I've tried most other avenues of trying to get it to boot, it did at one time but now I can't even get into my bios to re-do the settings? I did the Insert while powering up, same with the delete key while power up? neither seemed to do the job. Please Help, thanks I anticipate your expert response Michael I have worked inside computers before, but this one's got me perplexed?? 612-378-9173 imhookt1@yahoo.com

I need to rest password in bios


Hi,
Removing the RTC battery and leaving it uninstalled for 5 or more minutes causes all passwords and CMOS settings to be cleared. BIOS password can be removed by temporarily disconnecting/ removing the RTC/ CMOS (Coin-cell) battery from the motherboard.
Disconnect the coin-cell battery from the system board and it will reset the BIOS to its default setting and the password would be gone.
Please Refer to Page 29, 106 & 79 of the REPAIR MANUAL IBM T40 for Battery removal, keyboard removal and RTC battery removal instructions.
The Backup Battery (RTC, CMOS) is located under the keyboard. So you have to remove the keyboard to access the battery. The above Manual from IBM shows the exact method/ instructions and pictures for laptop dis-assembly for the purpose.
If you are comfortable with working inside such electronics, you can't do it yourself, or else you may seek help from local laptop service professional.


Hope it helps! Good Luck! Thanks for using Fixya!

I installed in my daughter ion laws laptop and need to flash bios so i can update it and it says password needed .She doesn't remember password ,how can I get around the password in bios?


Hi,

Welcome to FixYa!


BIOS is one important component of a computer, its where you can change some important settings inside the computer itself. Are you the one who set up the BIOS password? If not, unfortunately, there's no way for us to retrieved the password. The only way you can reset the password to default settings is to reseat the CMOS battery on the motherboard, its a circular thing that looks like a battery of a watch,sometimes a pin hold it, just detached it then wait for at least 30 minutes then connect it back again,


Note: Before you reseat the CMOS battery,make sure that everything is unplugged on the computer, like AC adapter,battery and all external devices...


Hope this will help...Thank you for using Fixya...

Hi promano67

When you "start" the computer, and the {"Screen"} displays a "Error Message."[CMOS] "error checksum!"

Settings: "Default" loaded.A "checksum error" shows that:

The ("Boot-up Settings "have been changed?"), ie. "Booting OS."

*Boot File 'missing'.

"This can 'occur' if the computer was "shut-down unexpectedly."

Force Shut-down : Power lost; due to 'low battery...'

A ("Power Surge") can cause this 'problem' also.

"What 'happens is that the [CMOS] settings are lost!".
"To fix the problem!"

Do the following:

  • "Restart / Boot the computer.

  • Next, verify if the 'error message' displays?

  • If you are still getting the message?

  • "You will have to "Remove the CMOS battery form the computer!"

  • Shut-down the computer.

  • "Unplug the computer from the {Wall Out-let}.

  • Remove the Lithium battery from the "Notebook."

  • There is a compartment (underneath) the "Notebook that 'store' the CMOS battery."

  • "You will need a {very small Phillips screwdriver}._953.jpg *Remove the CMOS battery for: [30 minutes].

  • !Important: If you have to do it again?

  • Remove the CMOS battery for a {'longer amount of time'}.

  • Replace the "CMOS battery."

  • Next, "Only plug the Power Adapter into the computer.

  • "Do not - replace the "Lithium battery!"

  • Once you have completed these 'task'.

  • "Restart the computer."

  • "Press the [F2] key, to 'enter' the CMOS / BIOS Setup!" _951.jpg

  • Next, 'reset' (all) "Values to the Default Settings."

  • "Press the [F10] key to 'Save' the changes!"

!Important: "Take a 'moment to rate the help', so I can get 'credit' for the work.

Thank you!" - paul7of9

I have a satellite A105 and When i turn it on it asks for password but I don't have the password. So how to I get past this to be able to use it again?


just remove the cmos battery

the bios stores the password and the cmos battery provides it power to store it

if you remove cmos battery the bios reverts to factory settings and the password is removed

cmos battery is different than the laptop backup battery

cmos battery is found inside the laptop case on the motherboard, you will have to open the laptop to remove the cmos battery

Hi!
If you already found the cmos battery, then try to check its "rating" and size to accomodate inside the board. After that fix it as it should be.
