If you need to remove the keyboard ...
there's a manual for this.

ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/42x3553_02.pdf

you start with the pannel with the on/off button, best to start on the right side with a flat screwdriver and pull it off. make sure the screen is pushed back far enough because the silver coverage of the screen screws goes of, too.
then you take off the keyboard, be gentle. first unwind the two black screws at the top. there are four of them, leave the ones on the blue circuit board alone.
when removing the keyboard be careful not to pull it off too qouikly, because the connection line is pretty short. to gett the line off, there are two grey handles on each side od the connection box on the circuit. push them towards the screen gently to unhook the connection line.

gist a question: where is the battery, or rather: what the hell does it look like?
on lenovo forums someone said that to reset the cmos, you need to circuit the contacts of the black and white cable next to the hdd. i thought the lead to the cmos, but now i saw the lead into the screen. so how exactly did he circut the cmos on those contacts?

I forgot user account password.. I cannot open the my system.. How to open my system


which operating system? and which name type/brand of computer?

When you boot up to the log in screen type in administrator as user to log in if you cant log in

during the boot up process you will see on the screen for a short amount of time press a certain key to enter set up press and hold that key during the boot up process to enter BIOS scroll down to set user password or supervisor password you can change or remove your password from there

also

The most common way that we 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 the Cmos 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 cmos the battery power, the BIOS/CMOS settings will be erased.
cmos battery Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment. Although on some motherboards the Cmos battery is soldered in Hope this helps you

I forgot my bios password of my laptop hp 6730s and cant even reformat it ? any help plz ? thank you so much .


You need to clear the cmos. This is accomplished by removing the cmos battery for 5-10 minutes.
1. Remove the battery 2. Remove the keyboard 3. Remove the LED switch cover 4. Remove the cmos battery cable from the motherboard 5. slide the battery out of the brack
Reverse the step after 10 minutes and the bios should be reset. On first boot you are going to need to reset your clock, settings etc.

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 cannot open my friendster account because i forgot my password.pls.help


Remove a small coin sized CMOS battery to store all BIOS settings along with the password. To reset the password, unplug the PC, open the cabinet and remove the CMOS battery for approx. 15-30 minutes and then put it back. It'll reset all BIOS settings as well as the password and you'll need to re-enter all settings.

Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.

If it fails, then try to remove the battery for at least one hour.

click start control panel Open User Accounts in Control Panel. On the Users tab, click the name of the user whose password you want to change, and then click Reset Password. In New password and Confirm new password, type the new password, and then click OK. Notes You can change passwords only for local computer accounts, such as guest, administrator, or accounts you create for your computer. You cannot change your network logon password in User Accounts. To change your own password, press CTRL ALT DELETE and then click Change Password

hope this helps

Can't boot and forgot bios password on ibm r50e


You need to remove, or short, the cmos battery. I'll be on the motherboard somewhere, possibly under the keyboard. Remove all screws, carefully, slide back any tabs on the keyboard and carefully remove. Only do this if your warranty has expired.

I can not clear password in CMOS/BIOS setup in my Laptop.


You must take out the CMOS battery its normaly located somwhere under the keyboard. When its out with power removed use somthing metal to touch the pins together on the board where it plugged in. (If you arent game to do this then just leave battery out for an hour or so) Here is pictures of different batteries so you know what they look like.

If you want more specific instructions then ill need a laptop model number.

Hi, the cmos battery is not under the keyboard, take the side off your PC and on the motherboard, (the first thing you should see) there should be a 3 volt battery (about the size of a 20 cent coin), remove to reset cmos. If you need any more help locating the motherboard just ask, Cheers
