I think the problem is illmaticone can't get into the BIOS it requests a password before it will let into the OS or the BIOS

Dell makes it annoyingly hard to reset BIOS passwords. Their official FAQ on the matter states that you have to call them and verify ownership, and then they will be able to help you in some way.

From what I've found, there's no button or jumper to clear the CMOS, but you can always try removing all power sources (AC, battery) from the laptop and then removing the coin cell battery. After a few minutes any residual charge should theoretically drain, resetting the BIOS and removing the password. After a few minutes you can try plugging the laptop in (but don't put the coin cell back in yet) and boot. Once you've verified that the password is indeed gone, power off the laptop, put the coin cell back in, and reassemble the laptop.

The Dell 700m service manual is located here if you want to look into this option. It would mean partially disassembling the machines, but I don't know how many other options you have here.

oh I hate to say this - but without some further explanation this really looks suspiciously like you are dealing in ill-gotten laptops - care to share how you came by these three notebooks?

there is some information regarding this problem already posted on here some where if you do some searching.

Wish I had thought of that idea of testing it before putting back the coin battery on the on eI was trying to fix oh well too late now

It's been researched thoroughly and results posted here (as Chastity said above) by a buddy of mine.

The password is programmed into an NVM memory chip on the MB, not CMOS, so powering off does not work.

There are crack sites that tell you how to burn the password out of the NVM chip. It requires applying a high voltage pulse to the NVM chip programming voltage pin and is not trivial. The alternative is replacing the surface mount chip which requires skill and preferably special tools.

There is no other way. The Dell laptop security is excellent.

How did you get 3 laptops with unknown passwords?
-Dumpster diving?
-Midnight requisition?
-Fraudulent Ebay auction?

I work for the department of education (ny) these laptops are for instructional use. when we recieved this shipment of laptops usually they are prep'd and set with a cmos password. well they werent this time, and the students had set the password.

i dont understand why some people would come at me in such a manner, maybe my low post? and new member? i dunno to bad i forgot my account information from 'xperience' days

Thats almost a good story if they are sent to you preped and passworded , I guess somone did not do their job, so send them back to the person that screwed up in the first place.

illmaticone - we come at anyone looking for crack information the same way unless we know them. This is an old, legitimate site with strong rules against providing crack information.

Considering the circumstances you'll have to put the repair back on the supplier. As I said earlier. Dell's are hardware protected to resist cracking. It can be done but with substantial effort and risk. Basically - burn the password chip clean manuually or replace the chip with a fresh one.

thanks for this big idea... i try do this by removing the battery but not the coin cell battery.

do i disconnect the coin cell battery connector by doing what you post here?

Pulling the coincell battery from a dell laptop will not remove a boot or bios password. As was stated above - that password is stored in NVM (non-volotile memory?) - so when the machine boots up again you'll get config errors (So BIOS was cleared) but you will still be prompted for a password.

I know this because I have the same problem with a clients Inspiron 2200 and I've already tried pulling the coin-cell battery. She received it when a tenent of hers declared bancruptcy and was locked out of his office. Apparently he told her to keep the laptop since he owed her a good deal (or so I was told).

Only solution for removing a lost password on an Inspiron laptop is to contact dell, do a transfer of ownership, pay them $50 for an out of warranty tech support call and they'll give you the master password for that laptop. If you come up with anything else - I'd love to hear it.

I would sure like to know who you talked to at Dell, as I spent 1.5 hrs on the Indian Help Line and was told at every turn that I would have to replace my motherboard..... this with proof of purchase... and the Admin password was already set when I purchased it from their Refurb site
