Thanks Helpstar. Will try it in morning when fresher. Now is time for a glass of Red in cool under pergola. Will let you know what happens. G
Thanks again Helpstar but unfortunately file is same one I have been trying. Beginning to think I now have a conversation piece or run as Desktop. Appears NO ROM file included in SP51315 package. Cannot understand HP would release an install file missing such a key component. Any idea what extension may apply for me to go searching just for the ROM file?

Accept I may be totally wrong interpreting the message and ROM file not meant to be included but if this be the case where on
earth is one expected to find it? Surely I am not only one to have this problem.
HP have deleted all support info files etc but did anyone create an archive somewhere?
One suggested solution is to do lower upgrades in sequence but can't even find any of those.

Info on this Notebook is so sparse and generally non complimentary. Was it a dog??
Any left field suggestions very welcome as am reluctant to just give up. Nil carborundum and all that.
 
maybe replacing the CMOS battery of the laptop can help as well

other than that, the ROM file is included in the BIOS update file in the link, but your laptop might not know it and it could be the wrong one. It´s only a link from an unofficial page.

Is there any other model no. on the bottom of the laptop visible?

Not been able to find any suggestion MUST be genuine but have found suggestion
BIOS should be updated for more recent battery build. This is only reason am attempting update.

Can't find any other info. Again many thanks for help. This has turned into something of a challenge.

A thought. Internet searching seems to offer no clear answer but conflicting advice.
Notice HP Battery for DV7-1026TX is rated at 14.3V but replacement purchased is 10.8V. (HSTNN-OB74;DV7)
Suppliers (several but maybe all same place) all suggest 10.8 IS compatible.
Could this be the answer I am seeking??
