I recently ordered parts to build a new pc, so I was planning on selling my current one to a friend. However, upon reseting the pc and then restarting it, I ran into an issue with “TPM” - Whatever that is. When the pc is booting up after a restart or powering on, the first screen you see after the word “LENOVO” (I have a lenovo y520t, model 90H7007AUS) is a screen that says “press f12 to clear TPM” or “press ESC to continue”. However upon pressing either keys or any keys, nothing happens. The screen then sits there for 3-5 mins before bringing me to the lock screen. I tried restarting the pc to enter the bios but it just goes straight to the TPM screen. Please help me as I am clueless and this is honestly the first time even seeing the TPM.
