Laptop is an Acer Aspire 3, A315-51-341M
Machine was very slow.  Took the latest Windows updates, including 20H2, but still very slow and showing 100% disk usage. Fixed that by disabling prefetch and search indexing, but still very slow.  Upgraded to a Samsung SSD, and the laptop booted up very quickly. But when I came to restart, laptop will not boot up and only gets as far as the Acer Logo screen.  It will not let me access the Bios, or safe mode, and a clean windows instal by USB stick does not work. The only thing that does work is Control, Alt, Delete, which resets to the logo screen.  Any clues for how to proceed?

    Press and hold power button till machine shuts off. Remove charger. Gently push a paperclip into battery reset pinhole for about 30 seconds. Plug charger back in. Try to boot it again. Jack E/NJ

    Reset did not work, but in desparation I took the complete back off the laptop and the screen burst into life!  Problem was the little CMOS battery not making good contact, so it was flat.  Cleaned the button cell, and euraka - functioning laptop again, and the cell is charging up correctly.
