Hi Laura, It is very likely that your machine's battery has run out altogether. It happened to me once, and I had to do a warm reset to restore the settings. The following snippet from the manual might be of some help. Geetha CRASH AND RECOVERY QUESTIONS 1. All of my files have become gibberish, and when I go into the Files menu, the titles are incorrect. This rarely happens to our newer revisions, but this sounds like a crash. In other words, there may be something wrong with your unit, but it may be fixable. Try a "warm" reset. If that does not work, you must do a "cold" reset, the i-chord. You do a "warm" reset to return all Braille Lite settings to their default values (except for the battery timer) without losing data. When you press a for-sign-chord (dots 1-2-3-4-5-6-chord), the Braille Lite says, "Warm reset, please verify". When you press a second for-sign-chord, it says "Okay". CAUTION: Do not use a warm reset within another command or while data are being transmitted. You can also do a warm reset when you turn on the Braille Lite. To issue the command, turn off the Braille Lite. Then hold down all seven Braille Lite keys as you turn on the power. Once power is on, continue to hold down the keys for about a second. Use the "cold" reset procedure only as a last resort. All settings are reset to their defaults and all files you may have created, as well as their data, might be lost. For about 2 seconds, press an i-chord as you turn on the power to the Braille Lite. You hear, "System initialized; Braille Lite ready; Help is open; delete all data in file areas, enter y or n?" If you answer, "Yes", it says, "Are you sure?" to really force you to think. If you still answer, "Yes", you hear beeps while the Braille Lite "cleans up" things. Your data is irrevocably lost. This process insures that no one can recover your personal data - a good idea when exchanging your Braille Lite for an upgrade or a repaired machine. 2. My Braille Lite turned on and is dead - no warning. A warm reset usually fixes this problem. But since the Braille Lite has no "battery low" message, it might mean that you've completely drained the built-in, rechargeable battery. Use the Braille Lite's A.C. adapter to plug it into an outlet and allow it to recharge. As long as you leave it plugged into an outlet, you should be able to use it without any problems. Once it's fully charged (in about two hours), you should be able to resume using it on battery power.
