I have HP laptop z book. Few days before its battery was got low and it went to sleep during working. after few hours I charged the laptop but when I pressed the power button the laptop power lights WiFi lights and keyboard back lights start keep on blinking continuously with a pause of 5 seconds. And laptop won't turns on. I tried to take off battery and press power button for 30 secs and put it on back but it didn't work. I also tried to power on directly on AC supply but it didn't work either. Please guide me what could be the issue?
