I want to remove batterie and work only with adapter until i order a replacment-i have to make sume jumpers-

removing cmos battery doesnt work no matter how long you leave cmos battery out been there done that , you have to locate cmos jumper on motherboard , remove main battery & memory cards , peel back clearish foil on motherboard near where memory cards install , should see jumper points on motherboard , take bread tie touch jumper contact leave main battery out stand up like book plug in power adapter , and turn on only until boot screen then shut-off , install memory card , remove jumper and try starting laptop , if it hasnt cleared password , remove memory cards and try jumping it again

The solution depends on whether your laptop was made before or after 2004. If it is a post-2004 model, you must call Dell Support to reset the password for you.

If it is a pre-2004 model, you can follow these steps:

Perform the safety steps in the order below.
Warning: these steps are for your personal safety and the protection of the equipment.

Turn off your computer, and then unplug the power cable.
1. Wait 5 seconds.
2. Disconnect all external devices.
3. Disconnect any telephone or network cables from your computer.
4. Press and hold the Power button while your computer is unplugged to dissipate static electricity from the motherboard.
5. Before touching anything inside your computer, ground yourself with a wrist-grounding strap or by touching an unpainted metal surface, such as the metal at the back of your computer. While you work, periodically touch an unpainted metal surface to dissipate static electricity.

To use the jumper to reset the BIOS password

Note: On the Dell Manuals page, download the Setup Guide or Service Manual for your laptop. Then refer to the System Board Components section for a labeled illustration of the jumpers on the motherboard.

1. Ensure that your work surface is flat and clean to prevent scratching your laptop's cover.
2. Remove the battery from your laptop.
3. With your laptop still turned off and unplugged, remove the cover.
4. To locate the password jumper on the motherboard, look for the letters PWD, PSWD or PSWDCLR.
5. Choose an option:
   If there are 2 metals pins under the jumper
   1. Remove the jumper from the pins, replace the cover, reconnect the power cable and turn on your laptop.
   2. After the Windows logon screen appears, turn off your laptop.
   3. Again, disconnect the power cable. Press and hold the power button for 10 seconds to release static electricity from the system.
   4. Remove the cover.
   5. Replace the jumper in its original position covering the 2 pins. This will re-enable password feature.
   6. Replace the cover.
   7. Reconnect the power cable and other connections, replace the battery and turn on your laptop.
   
   If there are 3 pins under the jumper
   1. Remembering which two pins are covered, remove the jumper from those pins.
   2. Reinstall the jumper in a different position. For example, if you removed the jumper from pins 2 and 3, reinstall the jumper over pins 1 and 2.
   3. Replace the cover and reconnect the power cable.
   4. Turn on your laptop and wait 5 seconds. Then press and hold the Power button until it turns off again.
   5. Disconnect the power cable again. Press and hold the power button for 10 seconds to release static electricity from the system.
   6. Replace the jumper over the original 2 pins.
   7. Replace the cover.
   8. Reconnect the power cable and other connections, replace the battery and turn on your laptop.
   
   You can now assign a new system and/or setup password. For more password information, refer to the Passwords section of your laptop's service manual.

Hi there,

Inspect the following components, in this order (with key off) until you get it working:

** Disconnect the plugs from the Horn terminals. Run separate jumper wires from the Batt (NEG & POS), to the horn. If horn does not work, then replace horn. If horn works fine, then continue....

** Check fuse # 10 (15A), in the Battery Junction Box - replace if defective. Check horn operation.

** Check Horn Relay (also in the Battery Junction Box) - remove the relay, give it a gentle tap, and plug back in. Check horn operation.

If all the above prove ok, then the fault lies in your steering wheel/horn switch assembly.


Cheers,

Yes on a dell motherboard there is a jumper used to connect and disconnect a battery that is attached to motherboard. In order to clear a BIOS password you need to remove the jumper for approx 30 sec and replace to wipe the password.

First of all, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. To to do this is to compare your laptop voltage & amp requirements (written on a sticker on the bottom of the laptop) with the voltage & amp ratings of the power adapter.

Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amps of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.

If the battery does not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.

If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.

If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing.

In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

Remove all power sources, ac adapter and main battery if you have one. Then disconnect RTC battery for 30 seconds. It is located under the tear shaped cover on bottom of computer. Reconnect RTC battery and ac adapter but DO NOT PUT BACK THE MAIN BATTERY until you have reset the date and time.


Please rate & vote , if you like solution..

Thanks

The best way for the Sony is to remove the cmos battery for at least 30 minutes. Remove the main laptop battery and leave it out. Make sure the power adapter is not attached. The cmos battery can be reached after removing the keyboard and is attached to the motherboard vis a small cable. If you have a "jumper" that come equipped on hard drives to jump the pins on the back, you can "short" the pin connections on the cmos battery socket, power the laptop up using the ac adapter and letting the computer go through the bootup process. When this happens power the laptop back down, take the jumper off and replace the cmos battery. Power back on with just the ac adapter and boot the computer. If the laptop still askes for a bios password just hit enter and it should allow you to log in. Once in go into the bios and reset the date and time. Once that is done power down and replace the main battery. Reboot the laptop and let Windows load.

Hi, You can try this

1. Turn off the laptop
2. Disconnect AC adapter
3. Remove battery pack, and remove the keyboard
4. Remove the battery (located underneath the keyboard, the red/white wire)
5. Leave it for about 30 - 60 mins.
6. Reconnect the battery and reassemble the laptop
7. Reconnect AC adapter (Don't put in the battery pack yet!)
8. Turn on the computer and press F10 to enter the BIOS
9. Set the new BIOS password and save all settings.
10. Turn off the laptop and reinsert the battery

If this does not work you can try and check out a manual for your laptop here.

Hi there

you might have a failing hard disk or motherboard, try clear c-mos battery and try again . Also replace any faulty ram and other hardware that may cause the problem , unplug FDD, CD ROM and other devices , replace keyboard and mouse
