    What did you change in the BIOS, give us the details, as you don't change any settings in BIOS if you don't know what you are doing😀? Try to go into BIOS and go to Exit > Load Setup Defaults > as that loads factory setup default values for all setup items. And see if this setting loads the PHN16-71 laptops default BIOS settings, if not then you need to disconnect the main battery and disconnect the RTC/BIOS battery and short its +&- ins to reset CMOS as that should work and your BIOS should be at default. Good luck.

    eldest77, I know that the bios battery is very small, but you don't short the battery leads but the mainboard plug +&- pins after you have disconnected the battery. Try that and if you can't get into the bios then you need to send your PHN16-71 laptop to Acer Support as they might still honor the warranty (I can't be 100% certain) as if you cant get into bios there is a bios programing issue or chip issue that the bios chip needs replacing or and what Acer do is they change the mainboard all together with a new board, which would be far too expensive and financially not worth doing, as for the price of a new PHN16-71 mainboard you can virtually buy a new laptop.
