How do you turn comme on ?

hold down Shift, press and release On, then release Shift.

Also, G2 Primes also go into coma mode automatically after being turned off for a few days. This is because normal off mode still uses a trickle of battery power, whereas coma mode uses much less.

You can easily tell whether your Prime was in coma mode or not when you turn it on, because turning on from normal off mode only takes a fraction of a second, whereas turning on from coma mode takes about 3 seconds. Although turning on from coma mode only requires a single press of the On key, it takes so long to power up that I sometimes mistakenly think that I didn't press the On key hard enough and so I press it again, which is totally unnecessary.

Please note that merely pressing On while holding down the Shift key is not sufficient to force Prime into coma mode. cdmckay is correct that you must hold down Shift and then press On, BUT you must then CONTINUE to hold down the On key for about 1 second before releasing it. If you don't hold On down long enough, only a normal turn-off is performed, as can be seen easily by turning the Prime back on. If your Prime is near a bright light source, you can also see something interesting when coma mode starts: the display's backlight turns off immediately but the LCD itself still shows the HP logo for about 5 to 10 seconds, until it slowly fades away.

P.S. If your Prime never goes into coma mode, it's probably a G1 Prime. Coma mode is only found in G2 Primes.
