As my fellow Treo 650 owners probably know, there is an LED light just above the screen that blinks constantly when the phone is on — red for no signal and green when a signal is available. Turning off the phone is the only way to get the light to stay off. Or so I thought. Today I discovered a free Palm app called LEDOff that silences the blinking LED light once and for all. The program is over 3 years old, and I can’t believe I never stumbled across it before. For someone like me, who spends hours every day staring at my Treo’s screen (reading books, mostly), this program is a sanity-saver.
LEDOff even let’s users select which events (battery charging, alerts, etc.) still light up. For me, after years of reading ebooks while that light blinked incessantly, it is now disabled completely on my phone. Sadly, modern Palm OS users often dedicate a significant amount of storage to a host of little (and not so little) programs to make their devices look and behave the way Palm should have in the first place.
BTW, if you don’t mind the LED light, here’s a little cheat sheet for what it’s trying to tell you:
| LED state | Meaning |
| No LED | Not charging, Wireless Mode off |
| Solid red | Connected to a power source and charging |
| Solid green | Connected to a power source and fully charged |
| Blinking amber once per second |
Wireless Mode is on, but not in an area of mobile coverage |
| Blinking green once per second |
Wireless Mode is on, within an area of mobile coverage |
| Blinking red rapidly | Battery very low, charge immediately |
| Single amber flash | Indicates a number of temporary conditions, such as detaching from data network, detaching from mobile network |
