My D550ma Power failure In the middle of surfing the net my Asus D550ma crash with power failure. It won’t power backup nor charge. It begin running real slow at startup before the failure. Any advice?? Thanks for your responses

You have to remove the battery, ac adapter holding down the power button for a minute or so. replace all back again and reboot . also : remove the laptop’s hdd from the machine. connect the HDD using a USB port (cable or external box) to test if the hard drive was the problem.
