Hi, my name is ***** ***** I will do my best to assist you.
whoever informed you that the CMOS / Bios password ***** be cleared for that model, is incorrect.
Please see page 44 in this service manual from HP. http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-c02030223-1.pdf
Follow those steps precisely, and you should be able to clear t he password.
If these steps dont work, then its not a BIOS password ***** rather a Drive Guard password ***** ( for the hard drive )
If thats the case, then you just need to replace the hard drive and t hen reinstall windows on the new drive. You can order a hard drive here.
Thats the lowest cost for a laptop hard drive over 300 gigabytes brand new, that Ive ever seen.
If you have further questions or concerns, let me know.
I strive to provide great service, and greatly appreciate a rating of excellent ( 5 stars ) selected and submitted below this answer or at the top right of the screen. I always answer follow up questions.
