Hi. My computer suddenly won't boot after a forced shutdown. The laptop was connected to an external monitor which had gone to sleep. Usually when I move the mouse the monitor wakes up but this time it didn't happen. So I unplugged the hdmi cable and the laptop screen didn't come back. Thus the forced shutdown. After which when I pressed the power button I got a brief fan spin and then nothing. After that I just got a brief light blink each time I pressed the power button.
The display driver diagnostic works fine. I also disconnected the battery and plugged it in. Still not able to turn on. However I I'm now seeing a blinking power light every 5 seconds.
Any help would be appreciated. Thanks
