Reset BIOS Password - Hard Drive Issue

Hello 

I've a  Studio XPS M1640 and when I run the built in diagnostics I get error 0142.  I've replaced the drive and still get the error.  The laptop is out of warranty. 

I can't get into the BIOS as I don't know the password.  I've tried disconnecting the internal battery and leaving it a few days, but the laptop has still retained the password protection.

Can anyone help?

RE: Reset BIOS Password - Hard Drive Issue

Hello MRNUCKY,

It is possible that the hard drive cable may be at fault or even the motherboard connector. Test these hard drives in a caddy to check if they work.

You may follow the instructions at http://dell.to/2sTXCk3, Section 2 and see if that helps clear the BIOS password.

If all else fails, you may need a replacement motherboard. Check with local or online vendors.
