How to remove cmos battey to rest bios in hp 2710p laptop

Hi Are you running win 7 32 bits?enterprise?

To reset the BIOS password read the information from this link.

In case of your HP TC4400 laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

I know some methods to reset bios password.
1. The best and easiest method: Close OS and shut down the electricity power of computer. Open your computer box, take out the cmos battery from the mainboard. Then the bios password will be reset to blank. Put it back after a few minutes.
2. Follow some hard tutorials, it is difficult to do. It is better that you are a expert. For example this tutorial: reset BIOS Password?

So I would suggest you the 1st method. Hope it helps.

Enter BIOS SETUP. Enter the current password.
Change it to a "blank" password.

Or, if you don't know the password, find the orginal sales-receipt, to prove to HP that you are _NOT_ a thief in possession of the stolen computer, and then HP will assist you.

A. By Using the Motherboard Jumper:

In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

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.



B. By Using Software:


I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

BIOS/CMOS Password Recovery Tool Service: http://www.biospasswordrecovery.com/

Remove the battery on the mother board, wait 5 minutes.

You can clear the bios password by removing the CMOS battery from the motherboard, make sure the PC is disconnected from any other power source, wait a good 3 - 5 minutes, hit the power button a few times to make sure all power is drained from the capacitors, and then replace the CMOS battery. You can then power on the PC and the bios password will be removed.

Thanks.

I haven't tried it yet, but according to HP's "Maintenance and Service Guide" (Available in PDF from their Support website) you have to completely break down the computer, remove the mainboard and the CMOS battery should be located on its underside. Remove it for five minutes, replace and reassemble EXCEPT FOR BATTERY and turn it on under AC power only. I just purchased one that needs reset, but haven't received it yet, so I cannot attest to its effectiveness except that this is deirect from HP. Hope it helps!
