When I was done printing I puted the laptop to sleep mode and went to my bedroom.When I opened I again the screen was black.Since this happened before I made a force shutdown.When I powered it on the screen was black again.Since then It started again one time because I removed the CMOS battery(I pressed F8 and it started again after a long time and I removed the battery and ran the laptop with the charger).Now because I removed the CMOS battery I wanted to correct the time and date so when the logon screen appeared I turned the laptop off.When I powered it on again the black screen appeared again.I pressed F8 again and nothing happened(the battery isnt inserted still).Since then I removed the CMOS battery,tested the RAM,waited 60 second and powered it on again and nothing works.After 1 hour of testing this solutions the laptop finaly turned on again.I logged in and everything works fine(the battery still isnt inserted).What should I do now.If it helps the laptop isnt up to date because something is wrong with windows update(error code 80072F8F),I unistalled the driver for teredo tunneling pseudo-interface but I forgot to install it again because I was doing my homework,the laptop needs 10 minutes to respond normaly with no problems(I applyed nw thermal paste because before tha laptop needed 20 minutes to respond normaly).Now I cant even acess the web because it says on google chrome that cannot access this website.I raned the troubleshooter fir the hardwere and devices department and it says the changes for the hardwere might not been detected.Since then I havent done nothing.
