I am experiencing an intermittent issue with one of my ZBook 17 G3's. When the power button is pressed, the ZBook will not boot. The WiFi indicator is amber and the sound indicator is illuminated white. No BIOS indication in the lower left corner of the screen, just blank. If I hold the power button down and press many buttons, i.e., WiFi, Sound and keys it will reset and then boot.
This has happened before and I was able to boot the computer if the battery was disconnected and reconnected.
Can someone provide me with some insight on the issue?
