after a power cut usually windows autorun chkdsk so that's why it's slow. but to be sure. run it with the chkdsk /r or /f ooption. as for second question i think it has some thing to do with the hard drive. being not able to wake up after sleep mode either data cannot be retrive in the hard or a memory problem.

i wrote before that i already try chkdsk -pc slow every time after shutdown
second problem happens even i unplug hard drive so it is not the hard drives
