What does it mean when three green lights flash

Alternate Red and Green flashing means bad battery. Buy a new one, or take it to a Makita Service center for replacement if it's under warranty.

Normally the yellow light indicates hot battery, but it could also mean dirty battery contacts so the heat sensor can't be read, or that the fan is clogged with dust and unable to cool the battery. The manual says let the battery cool and try again. If the yellow still flashes, it's contacts or the fan.

Read the manual online at:

the green is the reboot process and is normal.
the red light is an error code indicator.
count the blinks of the red light...it cant be 30 times (I think)
it will blink a sequence, pause, then do it again for a total of three times.
count carefully, it gives you three chances to catch the number it is blinking.

Phil after a full charge you should be reading more than 24.8 volts on the batteries I'm still leaning toward replacing the batteries of course thats not cheap but if you can locate 2 batteries from a provider that will let you try them on the scooter to see if that fixes the flashes you are getting I don't have too many more ideas to give you sorry

That model seems to have had a problem past and I would contact Samsung or a service engineer as it sounds in need of a repair to my mind.

Hope this helps........

If the light flashes 3 then 4, that is code 34 which means lamp failure.

It means the freezer is starting to warm.

Thye HDD can be either orange or green and will flash when the HDD is accessed

Ok the lightning bolt is your power indicator: solid green-charging, Flashing green-fully charged, flashing red-low battery, flashing red three times the once green-bad battery. the "trash can" looking one is your hard drive activity indicator it will flash while your hard drive is reading and writing.

Three lights flash red on the Ring of Light (RoL) on the front of your Xbox 360 console. The upper-right quadrant light is the only light that does not flash red. The three flashing red lights may indicate that there is a hardware problem with your Xbox 360 console.

You can try one or two things.

1. Turn on your xbox and check to see if the power supply light is green. If it is green there is a problem with the system. If it is red it means you should check your connections and restart the xbox.

2. These rings have a tendency of meaning that there is a problem with the system itself. Most companies sell extra insurance to cover this "ROL" Ring of life. You can contact Microsoft by calling them. The number is usually listed on the back of the video game booklets.

I wish you the best and I hope this resolved your problem

Happy Gaming
