I have had to deal with this issue in the past. These are the solutions that worked for me: 1) Unplug or remove the CMOS battery AND main battery OR check for BIOS jumpers on the motherboard. This will reset the BIOS password (this may not be an option on your model). 2) Contact Dell Support. Give them your Service Tag number. They will need to verify ownership, but will be able to unlock your device. 3) There are several online services that will provide you with a master password for a fee based on your Service Tag number. Do an online search. 4) Take the device into an authorized Dell repair facility. They can unlock the device for you as well. 5) There are lists of master passwords based on your Service Tag and laptop model ( I have had limited success with this option). 6) IF ALL ELSE FAILS - Replace the motherboard. The BIOS is encoded on a chip on the motherboard, which you can replace. For your particular model, it is only about $80. Link

No to offend, but that model is outdated and can only be upgraded to a maximum of 2GB. My recommendation is to get a new laptop, but if you still want to upgrade the RAM, this will fit. Also, there are a number of different memory configurators available where you input the model of your laptop and they will tell you what to use. Here are a couple: PNY: http://www.pny.com/support/memory-configurator Crucial Memory: http://www.crucial.com/usa/en/memory-info Kingston Memory: http://www.kingston.com/us/memory/upgrad...-2w7qOoqEMSJABauikX0kPCPn5A63BR9yrF-zsAwa01IbxUER0GIuNb79INIRoCH_zw_wcB
Which, passwords are you referring to -- the Windows OS passwords or the BIOS passwords. IF it is the BIOS passwords, then NO -- replacing the HD will NOT remove that password. You may need to contact HP and prove ownership for them to reset that password.
Look on the bottom of your laptop. There might be panels that are removable that will give you access to the RAM modules. If not, you will have to unscrew and remove the bottom of your laptop to gain access to the motherboard and memory modules.
