My HP EliteBook 840 with Windows 8 will not turn on at all. When I tried to turn it on, the keyboard started blinking, but still didn’t start up. Is there something wrong with the power system or something else?
What lights on the keyboard are blinking and is there a "pattern" to the blinks, e.g. 2 blinks - pause - 2 blinks - pause or 2 blinks pause - 4 blinks - pause - 2 blinks - pause etc?
have you tried starting it with the charger connected?
