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.

Try Fully charging the most electrical equiptment have a reserve built in its battery so you are able to switch on by going off again Batteries need fully charging. If you have done this then your battery does not hold its charge Sorry but they need replacing.

How long should you charge ur f&p voyager mobility scooter..after a trip of say 5-10 km ...i dont want to overcharge it and fry the new batteries.(2x 20 amp hr)


Hi. 20 amp hour batteries are rather small for one of these machines. You can fit up to 55 amp/hour batteries in these.
These machines have to have the programming changed for different charge rates for different batteries,e.g. Wet cell, sealed lead acid or gel cell.
These machines have a fully automatic charger that drops down to a float charge after the batteries have been charged. You cannot overcharge them. At the very least leave the machine on charge overnight after each use.
Batteries are built to do so many charge cycles, and the more they are discharged while using them the less cycles you will get. If you only use 25% of a batteries reserve you will get more cycles than if you use say 75% of a batteries reserve.
Good luck. Neil.

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.

Not really a problem. Just would like to know why my truck has 2 batteries? And what does the 2nd battery control? I have a 2001 Chev. 2500HD with an 8.1 Gas.


There are a few reasons for having 2 batteries.2 mall batts ,are the same as 1 large one,2 large batts,give you twice the cranking endurance,or if it has alarge motor then you need the reserve power to turn it over in case it is slow to start,like in cold weather,also if the vehicle has an isolator switch you can run on i batt. and keep the other in reserve or use it to run a fridge or whatever or r pretty much do as you want without ever having to worry about a flat battery.I always have aduel batt ,set up in my landcruisers to go bush and would never be with out them.

Bios password


here are the instructions


-Remove the hard drive.
-Remove the keyboard.
-Disconnect the reserve battery cable from the system board connector.
-Pry the reserve battery free from the system board. The reserve battery is attached to the system board with a piece of adhesive tape.
-Remove any remnants of the adhesive tape from the EMI shield.

Step 2
Make sure all power is off/disconnected and batteries removed before attempting anything like changing parts
in HP > Compaq nx6310 is in a easy to get-to location, but changing it is a pain. Remove your main battery, you'll see a small square of silver plastic in the middle of the compartment. The CMOS battery is underneath of this square.
The battery's connector is on the mainboard, just below the area of the "ALT" key. Unfortunatly, you have to dissasemble the laptop to change it.
