the PC is like a factory refurbished, back panel changed, and maybe mobo( not sure). back panel is clean, no DMI details on it. I also did not do a bios backup before giving seller to fix it. any other way to help. thnx...

Got a used HP Elitebook 855 G7, I noticed MPM errors, bios errors, missing SN, product N, featurebyte and so on. gave seller to fix and collect it after 2days. on receiving the PC I noticed touch-screen not working, when I checked more details, found out it has been given DMI details of HP Elitebook 845 G7, instead of HP Elitebook 855 G7. seller has refused to help further. I need help on this. difference between 845 G7 and 855 G7 is the screen and touch panel (14in vs 15.6in with touch). same bios family S77.

Thanks
