CMOS 502 Error followed by 3F0 from Bios Update

[skoop1]

Tried logging into my 2 year -old HP Notebook AY018-NR but it had a black screen. Could not get into safe mode but after a couple of restart cycles, saw the CMOS 502 error. After hitting Enter, received the 3f0 Hard Disk error. Given below is the System info I could salvage from the Bios setup screen (F10). Looking for help from experts to resolve error.

With the diagnostics (F2) for the 3F0 error, the memory checked out fine, but the Hard Disk was not recognized - neither in the Quick check nor in the Extensive check (received the check power and cable connection message).

I followed instructions in the BIOS recovery help site, but no difference - received same series of messages. Windows + V seems to be working on this laptop, but the BIOS recovery did not help (even tried going back a few versions but to no avail). One thing I noticed is that the System Board ID is 81EB, but there were no files in the BIOS recovery folder with that number (there were some for 81EC onwards).

Please help resolve the issue - if the Hard Drive is fried, I can try to replace it, but did not want to open the machine unless that is the best step forward. Appreciate the help in advance.

At least one of the above should be relevant.
