I've already given hdd serial num service tag express service tag and white sticker serial under battery for motherboard.
I can't do anything why should i have to go buy a new harddrive and reinstall windows to use my laptop that's under warranty
I have 4 numbers now for dell
18004563355 and 3 others
I first called about a bios password that was given but after it was erased the bios that is now i am being presented with a hdd lock 3 times and it shuts off no error code this is not a 595b legacy system i am familiar with dell but this is more work then requesting a carrier subsidy unlock.

I acquired a Dell Latitude E5520 that I redid myself and downloaded the drivers from Dell's website. I would like Dell quickset x64 for windows 7. The one I had for my old laptop does not work. I tried googling some but can't find it.

We have an unusual problem with a Dell Latitude E5520. It has been built with Windows 7 32bit SP1 and McAfee EndPoint Encryption, as we do with all of our laptops.
When the laptop is powered on and then docked, everything works fine. If you then give the laptop a restart whilst docked, it just doesn't! It shuts down and stays in some kind of power save mode. I have been through all of the Power options, including closing of the lid and turned off everything that could be causing this to happen, but still nothing.
If the power button is pressed whilst docked, the light comes on but that's it, no activity. Undock it, power up, close the lid and dock it again, all of the external screen, keyboard and mouse work as you would expect. I believe all of the drivers are up to date (it is a new laptop).
The docking station is an E-Port Plus DP/N: FFCV6 A00

I just got my docking station for my Dell e5520. I got the one monitor to work with the VGA set up. I would love to get the two DVI monitors working instead of one monitor. I am not sure if this is possible or not. If it IS possible, how do I go about doing it?

I have a Latitude E5520 that is having some strange issues. If I have i plugged in to a power cord, close the lid and disconnect the power cord, the unit shuts off. Sometimes when undocking, the unit will shut off as well.
I have checked the power settings and confirmed that when the lid is closed, no action should be taken.
The battery is fully charged and the laptop runs fine on the battery.
This has the latest BIOS revision A09.....

When I first got my Latitude E5520 (i7, 8Gb RAM, Intel HD graphics) I could connect to a Citrix based VDI desktop with a screen resolution of 1920x1024. Suddenly it dropped to 1280x760. I have never been able to get it to shift back to 1920.
The Citrix client has been replaced with both available options. Same result. Every possible configuration setting has been set to 1920x1024 to no avail.
The native desktop is at 1920x1024. Shifting into the VDI session, the only screen resolution offered is 1280x760.
I have also reloaded the graphics driver. Same results.Going into the advanced graphics configuration on the laptop confirms 1920x1024.
Other laptops allow me to log in to the same VDI desktop in 1920x1024 resolution so it is isolated to the laptop itself...

I have a Dell Latitude E5520 and lately it has been extremely slow, and characters on screen tend to lag far behind my keystrokes occasionally not appearing at all. Sometimes when I click on a button it will lag for several seconds and then go through, other times nothing will happen at all and I will have to click the button again and it works. Recently the laptop was taken on a plane and the in-flight wifi was used, that is the only thing done recently outside of the normal routine.
I have booted into safe mode and the lag still occurs. I have antivirus software installed and up to date.

I have an XPS M170, and it has a BIOS lock that only allows 2gb of memory. I want to put in 4gb (2gb x 2).
Called Dell, they said not supported... so that pushes me here =) Anyone unlock their BIOS before to allow more than 2gb of ram?

I've a Dell Latitude d630 Laptop and I want to change several BIOS characteristics (Boot device order, etc)
The laptop service Tag is <ADMIN NOTE: Service tag removed per privacy policy> and I had the admin PSW: oqzbww34
Last year my son changed the admin BIOS pw and now I can't change this parameters (I can enter at BIOS but can't unlock setup to change boot order, etc..); the old admin pwd doesn't work now
I've opened the laptop and disconnected de CMOS battery but this didn't work
Is there a master pwd to unlock bios setup or a jumper in motherboard to reset admin pw?

I bought aDell Latitude E6410 laptop yesterday and every time it turns on it says no boot or something. So I push the enter button and it resets. Then when it shows the dell logo again I press F12 and go to the boot sequence and its set on cd drive and not the internal HDD. So I choose to redo that all over again and then press boot from internal HDD and it works no problem but its a lot to go through just to start a laptop. How can I figure out how to change the admin password so I can set the boot sequence right.

I used to be a Dell Technician too, 578260. I got a latitude e6430 given to me from the company I am currently working now Prodagio Software. I am locked out of my BIOS but manage to use the laptop using finger print. I forgot my password and with that problem I am not able to modify anything inside the BIOS. I am afraid to do a reset because I might lose the A08 upgrade.

Why won't mine unlock? I've flashed JuanLu's modded BIOS like twenty times, and it won't unlock for CoolBits. So I'm stuck with using NiBiTor.

Recently I purchased a Dell Latitude D830 motherboard as a replacement for the damaged one in my own system.
The seller didn't tell me that the system has a customized bios and a password, instead he announced it as 'password free'. The board is working and I can enter the BIOS but all settings are locked with a password.
As the seller refuses to take it back, I need to reset the system. The first owner of the board is known and I have the service tag ready. Is there any chance to reflash an original DELL BIOS and to reset the password(s)?

I purchased a Latitude D505 from a police auction and the BIOS setup is locked by password. It will not allow me change setups, such as system time.
Under system security it shows Primary Password unabled, Admin Password Enabled, Configure Setup Disabled and Configure Password enabled.
I need to clear these in order to setup new HDD and operating system.
If needed the present sys number is #6M81L51-595B

I’m testing some E4200s (with SED SSDs and regular SSDs) and have run into a possible bug with the HDD password “bypass” option in the BIOS. The “bypass” option in BIOS allows you to specify if the HDD password needs to be entered during warm boots (restarts), standby, etc. I’ve set it to “disable”, which means that the HDD password must always be entered (even for restarts). However, the E4200 does *not* prompt for the HDD password during warm boots (restarts). It correctly prompts for the HDD password during cold boots and standby/hibernate only. I’ve tried upgrading the BIOS to the latest version (A13 to A20), but that didn’t work.
At this point I think it's a bug in the BIOS. I've tried this with different e4200 laptops and different drives (regular SSDs, and self-encrypting SSDs).

My dell laptop can't turn on. When I press power button, there have no activity. I see Num lock LED is OFF, Caps Lock LED is ON and Scroll lock is always blinking. LCD screen not display anything.
Here is the screenshot of my LED blinking.
1. I dissemble my laptop and remove unnecessary components and cable. I have tested and connected only with Motherboard , CPU and RAM.
2. I tried to replace with new RAM. But it can't solve problem.
3. I tried to remove Battery, only AC power can't solve problem.
4. I tried to replace new CMOS battery. But it can't.

I just ordered a Dell Latitude E6500.
Now I'm looking to get a cable lock for it. I know they are not the best at protecting your laptop, but some protection is better than none, besides I just want to lock down to a table while I need to run to the bathroom for a minute.
So, from personal experience, if you have a Dell Latitude E6500/E6400, what locks work/fit best for it? I've done some research and I've tried to read around(couldn't find much on here for the specific laptop).
So far I'm looking at these two (but I have no word from latitude E6500/E6400 users): ..
