it may sound strange but try this - remove the battery cover and keep you phone in sunlight for 2 hours and than plug the battery back and wait for 2 min . try restarting the phone and now plug the charger back and see if this works . it worked for me when i had the same issue back in 2009 . thanks for asking

i think i can give you some tips about this - 1- just remove the battery and turn off the charge and laptop . 2-rest for 2 min and than plug the power(Battery) back to laptop 3. press the power key and hold it for like 1 min and restart the computer if this does not work try restarting the computer in safe mode 1- just restart the computer and press f8 and select safe mode and once you are in computer try updating windows and graphic driver and remove some of start up programs which might can create issues

i will suggest try doing a reset . just hold the power key for 1 min and restart the computer and see if this works for you .
