Dell Inspiron 3521 :: BIOS Password Lockout
Jan 19, 2015
I have a friend whose father owned an Inspiron 15 - 3521 and died several months ago. Another friend of his tried to unlock the user password and somehow ended up screwing it up more, so now it boots asking for a BIOS password that no one has access too. He doesn't have the receipt for the computer, because his dead father was the owner but he does have the box. Its warranty is expired as well, but I was wondering if having the box was enough for Dell to generate a BIOS bypass or what other options are available.

This is an older laptop that I'm working on for a friend. She don't have enough money for tech support or anything like that. I went through the system to change the ownership to me, hoping that it would facilitate the process.
The only good thing is that I can still boot from a USB drive, though nothing I've tried from that angle works. The HDD is locked down, of course.

Everytime I boot up the laptop, I get halted with the blue box asking me for the bios password.
I know this laptop is quite different and that even removing the cmos battery for like a day is not going to help. There is no 24xxx chip that I can short on the mobo.
Then I found SST39VF040 bios chip on the back of the mobo and also found a 93lc86 bios chip too .....

getting the password for a Dell N5110. A friend of mine was having display problems so we tried resetting factory defaults and now we are completely locked out of using the computer.I read on some previous posts of DELL users saying message me the details, with proof of ownership however the posts were a little dated, is this still a viable option, and in which case who do I need to message?

I have an Dell Inspiron 6000 Laptop that has a Bios Password Set on it... and the password is not correct that we thought was the one for the laptop.... The password authentication system wont boot the laptop up until we enter the correct password... I have tried all the combinations that we thought the password is or was, but have not had any luck --- that being said the laptop is registered to me/ owned by me --- Can I provide the computer system tag -- that is shown on the screen and getting a reset password to overcome this obstacle.... The service tag is in my profile information and the computer system tag on the laptop bios password sign in screen is B*B*H*1-595B... I intentionally put the three * in the info, so I wouldn't compromise the service tag for my laptop for the world to see and use..

I have set an admin password for the BIOS of my dell inspiron e1505 laptop. I do know the password. But, is there some way for me to completely delete the password? Essentially I want to be able to access and change the BIOS settings without needin an admin password, the same way I used to before I set an admin password for the BIOS.

i've gotten a Insperion 1501 from a customer. The BIOS and HD require a password. Dell laughs when i call about this issue. Does anyone know the backdoor passwords for this model?
I have pulled the batteries and plug and let it sit over night, the password s still on the machine.

I bought my dell 3521 laptop on sep 2013 , I shut down the laptop last night now I couldn't turn on the only thing I get is power light on without blinking No fan no had to switch off I need to remove the battery no other way. I removed the battery and hold power button for 1 min to remove static power but nothing happens. Tried with new dell 65w AC adaptor but no luck only getting power light on.
Is that my battery is dead? Laptop will not turn on by only AC adaptor ? Coz even only with AC adaptor only power light on without blinking nothing else

I've had a Dell Inspiron 15 3521 since May 2013; it has been updated to Windows 8.1, 4GB RAM, etc. It's been a great laptop in all honesty.
However, in the last few weeks, I've had some issues with the laptop booting up. Originally, it would turn on, but then stick with a black screen (no other sounds of the computer starting up), and then beep 7 times. Per another forum post I read, that's indicative of a Processor Failure.
In this case, I'd remove AC Power, the battery, give it about 15-20 seconds, then reconnect the charger. The laptop would turn back on, no problems. I'd end up popping the battery back in a little later, and it'd charge with no issues. This has been my fix in the meantime for the last month or so.
Now, I can't get my laptop to even register that it's connected to AC Power. It'll just stay black, and then beep 7 times in a row repeatedly. I've tried using another AC Adapter, in the case my adapter died, and no such luck.
What are my options? My laptop is no longer under warranty, though I do have my service tag.

When I start my laptop, I hear 8 beeps and nothing appears on screen. This keeps on happening until I keep it upside down for 2-3 minutes. Than after it startups normally and works fine. This happens everytime I start my laptop.

From last 2 days, I have seen that my laptop 3521 Dell doesn't switch on at all. Second thing I have observed is that, when I have my charger connected to the plug point (not connected to the laptop), I see the green light on the charger as ON, but the moment I connect it to the laptop, the light from the charger turns OFF and ultimately, my laptop doesn't charge. I mean no power supplied.
The steps I have carried over so far are -
1) I have tried checking the laptop battery by taking it out and reputing it in the laptop and trying to see if it works, same problem.
2) I have tried checking if everything is okay with the charger, but still the same problem.

My dell inspiron 3521 keypad is not working i have updated all the software and system update is on.
i haven't installed any software, third party application or anything else like that which interferes with my keypad functioning.
I tried to update the drivers for the keyboard from device manager but it showed that the driver is already up to date.
I also checked the ribbon that connected to the keypad with the system hardware and there is no problem in the connection there also.

I own a Dell Inspiron 3521, and I'd been having an issue with apps not opening and closing when I do try. I went to fix this error. That's when I made a grave mistake. Somewhere along the line of me trying to fix it, I messed with something I shouldn't have and when I finished with my task, I was told to restart the computer to activate the settings. After I turned it back on it seemed normal up to the point after I saw the dell logo. It went black. At first I made the assumption that since I changed settings that it was still trying to configure them. But soon after, I saw my mouse and a little signal flash in the bottom left of my screen. So I checked around and found out that I needed to reinstall windows with disc or USB. But I don't have access to either of those.

I ordered Dell Inspiron 15 3521 (with Intel Celeron 1007U) online when the website said this has optical touchscreen capabilities. But when I got it (2 days ago), the touchscreen is not working and I don't think it was installed on the laptop. Will Dell exchange the laptop for the tochscreen free of charge?
