SOURCE: admin password dell c840 latitude

you can search for a password boot disk which will disable the administrator password. There are dozens of these types of programs but one program I recommend is windows password reset 6.0

Follow the instructions:

1.Free download the iso file : http://www.resetwindowspassword.com

2.Burn it to a disk to create the boot disk, that simple.

3.Configure your pc or laptop to boot in the cd drive,

4.Insert the CD, reboot from CD drive, and then just follow the process of instruction. A few steps later, admin password would be cleared

Took about 5 minutes for the whole process.

Adapter does not chanrge


make sure its plugged in correctly and the wall plug is plugged tightly. I had a Dell C840 when the
charger got power it had a green diode that lit up. You could test your power supply with a volt ohm
meter. if the VOM is not showing any power coming from the power supply (assuming you have the
VOM setup to match the power output of the power supply) then the power supply is probably bad.
If it works then it could be the computers connection or battery.

How to reset bios of my dell latitude c840????


I've had to do this before. Call up Dell tech support and assuming you can provide proof of ownership then they'll give you the reset code based on what's on the screen when you try to log in to the BIOS.This is the best way to solve that issue.

Even if you cannot prove purchase proof they will give you a reset code. Just contact them removing battery and other suggestions will not work it is a dedicated BIOS on a separate chip. I hope that this gets you pointed in the right direction. Just go to Dell.com Thanks for using FixYa! John

Dell C840 no power is there is a fuse?


Hi

Thank you for your query

Please try the following

1) Ensure the fuse in the socket has not blown,
2) Try to obtain a replacement power lead to ensure the lead is not faulty

I would not recommend that you open the Laptop as only qualified engineer's should carry out this work

If this has been useful please leave postive feedback/vote/testimonial - Thank You Again
