Dell d340. need to enter admin password in bios to reorder boot sequence to accept usb first - its locked and i cant remember password. tried removing cmos battery and replacing but no good. help!


Try the backdoor password Dell

With a PSWD Reset Jumper Step 1Open the access panel to the password reset jumper if your Dell laptop has one. Consult your manual for the access panel's location. Some access panels have a tab you slide, while others are held in place with a screw.
Step 2Pry the plastic cover off the reset jumper with your fingernail. The reset jumper is a small pin port labeled "PSWD" with three pins. Put the plastic back onto the jumper over pin 1 and 2 instead of 2 and 3. Wait 90 seconds.
Step 3Pry the plastic off the reset jumper again and place it back onto the number 2 and 3 pins. Turn the laptop on. Repeat step 2 if the password is still present. Leave the plastic clip on pins 1 and 2 for a longer duration than last time.

Without a PSWD Reset Jumper Step 1Locate the reserve battery, also known as the CMOS battery, if your Dell laptop is not equipped with a password reset jumper. The CMOS battery's location varies among Dell laptop models. Consult your manual for the battery's location on your specific Dell laptop model. Many Dell reserve batteries are located underneath the main laptop battery. Remove the main battery and look for a sticker under it with instructions on removing the secondary CMOS battery.
Step 2Remove your Dell's reserve battery per the instruction manual or sticker located under the main battery. Removing the reserve battery resets the laptop's BIOS password. Wait 90 seconds, then replace the reserve battery. Reconnect the main battery.
Step 3Press the "Power" button to turn the laptop on.

Can you buy new batterys for laptops from yourshop and what price our they please


Yes you can buy new batteries even for old models long since discontinued. I am not sure what you mean by "yourshop" but here are links you can try. You need to research your computer make and model number and possibly the part number of the battering. You can even find batteries on ebay - however I highly recommend using an established vendor with a guarantee selling new batteries.

Where is cmos battery located in Dell d505?


It's called the Reserve Battery in a Dell Latitude D505.
(It's also called an RTC battery in others, {Real Time Clock battery}, and CMOS battery in older laptops)

1.Remove the AC adapter if plugged in. (Charger)

2.Remove the Battery.

3.Right up against the outside edge of the battery compartment, in the middle. you will see the battery latch.

Push it down. The Reserve Battery Cover will come loose at the top. Rotate the top, towards the inside of the battery compartment.
The Reserve Battery is right there.

Pull the Reserve Battery towards the battery compartment.
(Comes right out of the small rectangular compartment it is in)

(It looks like three round coins put side by side, and has a green plastic coating around it.

In actuality, there are coin sized watch batteries inside that green plastic cover)

You will see a Red wire, and a Black wire twisted together, that go to a small white connector. The connector is two piece. Separate the connector, and you can take the Reserve Battery out.

Lose all battery power within minutes when not plugged in


Laptop batteries typically need to be replaced every couple of years or so.

Much like cellphones, if you overcharge them then you can ultimately kill cells and keep if from holding any juice.

Good way to keep this from happening in the future is by simply monitoring the amount of charge your battery has while its docked at an outlet.
IF it has a full charge simply take it out and use it on ac power and reserve the battery life for when you need to be mobile.

A new battery can be found either on ebay or directly through the manufacturer. Steer clear from off-brand replacements as I have typically seen a high failure rate.

Hope this helps.

How to remove the cmos battery on a dell precision m60


Here is the link to removing the reserve battery. http://support.dell.com/support/edocs/systems/wsM60/SM_En/reserve.htm#1123661
However, if you are trying to bypass a BIOS or HDD password removing the battery will have no effect. Those can only be removed by tech support or a hardware replacement.

I need to reset the password for the bios.


If you have a bios level password enabled and do not know the password, then you will have to contact Dell Technical Support to get a MASTER PASSWORD to disable it. There is no hardware path on a Dell portable (Aside from replacing the motherboard) to get around the password. To resolve:
  1. Contact Dell Tech Support2.gif (800-624-9896 USA)
  2. Validate that you are an authorized user of the system
  3. Once done, TS will generate a master password for you.
