Question about Dell Inspiron 6400 Notebook
i just purchesed a laptop, dell inspiron6400 from ebay, and it is locked with a password .. its like a cmos password of something , i cant get passed no matter what i try, please help if you can.. its a gray and white screen that loads up asking for a password ..
You will have to go into the laptop I am affraid.
If you are not familiar with the internals of laptops I would advise you take it to a laptop service centre near you.
If you are confident then read on..
Remove the battery and mains power from the laptop.
Remove the plastic strip between the keyboard and the bottom of the screen (where the model number is printed)
Pop the keyboard out (careful of the connector ribbon)
Under the keyboard there is a metal cover. Remove that (keep the screws with it)
Under there if you look closely at the motherboard you will find a marking of CMOS with 2 solder pads side by side right next to it.
Press something metal between the 2 pads for a few seconds.
Before you put it all back together, just reconnect the power button panel, and use mains power to try and start the laptop. If all is well then the cmos will be clear and the password will be gone.
Failing that (or instead of that), remove all power to the laptop, and disconnect the cmos battery for 10 seconds. The cmos battery will look like a blob of plastic that has 2 wires going to a connector. It will be very small (the connector)
