Hello, new poster. I have an Asus laptop, L510MA, after last window update, the battery light instead of green, flashes red, and I before had about 5 hours of battery life. Now it would die as soon as I unplugged power cord. Decidred to do a rollback, right off noticed my rollback dates missing, also my recovery partition was gone. After some searching on the net, decided to login to safe mode, and remove last updates. Now the problem, the fingerprint sensor does not work to login, and it also does not recognize my pin login, wants me to set up a pin, but without access to the play store for the app to do so, seems its just stuck. Any suggestions as to get it back to at least my old windows or into safe mode? Knowing me I am probably missing something simple (I hope), but as of right now I am clueless. Thanks in advance, Jim.
