Thread Starter 
My Dell Lattitude C850 just show an initial screen asking to enter the BIOS password. Does somebody knows how to remove or reset this password. I'm already remove the internal batteries, RAM Memory and disconnected HDD for a period of time and it still the same. PLEASE SUPPORT!!

The CMOS battery connects with the palmrest. Remove the keyboard from the system and unplug the palmrest for several minutes. If the password isn't cleared you'll have to call Dell. Mind you if the service tag comes up as stolen well, you're out of luck.

Have you owned this for a while and it just now has a bios password? Or did you buy it from Ebay and it has this password on it? A guy I work with bought a Dell Laptop from ebay, which seemed like an alright deal, wasn't super cheap. He got it and it had a password on it before it even booted up. He called Dell and they insisted that the laptop with that service tag was in a warehouse in texas or something and couldn't help him. So we looked on line and there were a bunch of places selling the "secret" to get past that password. Some were password generating programs that used the system tag number, others were instructions that involved paper clips to short some chip out.

Well, they were a couple bucks to buy, so he figured he had already spent a couple hundred on the laptop that he can't use, what is another $20 to try. Needless to say, none of the "secrets" worked and he found out he bought a $300 paperweight. So we went to a place here in town and bought a stripped out dell case of that model, that had a motherboard in it. And we just moved over the hard drive, lcd screen, memory and video card.

But we never found a way to get past that initial boot password. I hope this isn't the case for you.

any systems yours included can be reset at the amtel chip. you have to know how to short quickly pins 3 and 7 on the chip while under power. alternativly you can power pin 7 with a power source but paperclips and small bits of wire are cheap. I built a sadel for reading them so a simple flick of a switch resets them with voltage. just depends on if your local store does more then just move componets around. There is no sercret in those amtels you can go to the manufactor and they will tell you how much voltage erases them. Heck i did the same thing and i wrote and took pictures of what i did i sold that info on ebay for 1 buck. made enough to pay for a new laptop but that was just so i could get rid of the oviously stolen one i had bought and had to errase. Since then i have done many bios unlocks and charge 100 bucks for it but i download that eeprom and re-record it back once i remove the password function. The only downside to errasing it is you loose your service and asser tags inside the system. another words no warrenty unless you jusrt download it and re-write it minus the password block.
