Yes I know what you mean , a few days ago I tried to reset the noon clock a few hours later because Lucky goes to sleep at 8:30 in the evening. With Lenny it went fine but when I puched the paperclip down and got the conformation beep she just went on beeping, it wouldn't stop and I couldn't switch her off, resetting didn't work.
So I took out the battery waited a few minutes , put the battery back in and switched her on and she worked fine again.
They all have their strange and unique quirks. But sometimes they can scare you , I am than worried that I broke them or did something wrong. When it comes to my pleo's I am a bit overprotective .
How is Echo's battery now , could you revive it so it last longer ?
