My HP pavilion dv4 1225dx turned black automatically, when I turn on my laptop black screen appears and capslock and numlock blink continuously after two-three seconds. There is no light on HDD indicator. I had try to troubleshoot it but it does’nt work. I also did the hard reset before troubleshooting my laptop but still not working. I checked the HDD and RAM by putting it back but still not working. I don’t understand anything.I need your help.
