- NAV + PWR - to call Service Function window (see below)
- NAV + MENU + PWR - to force power off, equal remove batteries.

IN + PWR helped to power up my unit.

SOURCE: my garmin won't turn on. I have tried the plug in
it does have an internal battery, but that normally wont prevent it
from turning on unless the battery is defective.
plug it in to the usb cable on your computer for a while (normally it will start right up) then slide to power switch to the on position for about ten seconds.
if that fails, press and hold the lower right corner of the screen and then slide the power switch to the on position while holding the lower right corner of the screen and follow the directions once it starts
i can give you something else to try before you go and spend money on a battery...a battery should be the last thing to do, even though it will more often then not fix the problem thats tempory..
if it turns out you think you need a battery, i will point you to one with instructions on how to change it.
