I didn't dismiss all the solutions, If that's how it came trough to you I'm sorry.
The thing is that I don't like workarounds because that's never a solution. It's like looking the other way when there still is a problem. If I ignore it I can't upload books by example. But I did spend time troubleshooting and found the problem and solved it. When it connects to a PC it creates 2 mass storage devices. One with the actual data and one called 'SETTINGS' and got some software on it. I disabled the software drive in my device manager and now I can plug and charge it without any draining problems at all. It's a strange problem and I don't think anybody else will get the same thing with their reader. Because it's managed now I don't need to return it. It just works fine when you know how to handle it. Thanks for all the tips and I'm glad that I don't need to worry again about this |

The settings drive is for the initial software install when you first get the reader and shouldn't do anything else... maybe something set in your W64 was accessing it or trying to get it to continuously operate... glad your solution works but wonder why it occurred in the first place...

You do know that USB and other removeable devices are SUPPOSED to be ejected, not just disconnected?
Try that first. |

As long as you are certain that the device is not being written to when you unplug it, then it makes no difference whether you eject it or not. I just make sure that sufficient time has elapsed since accessing the device in question before unplugging it. In fact you can make this even safer by turning off write caching on the device. In Windows open Disk Management Right-click on the USB device in question Choose properties from the menu. Click on the Hardware tab, look for the properties button down in the lower right-hand corner, and choose the Policies tab. Turn off write caching, then you never need worry about corrupting the data, before ejecting the USB device, just pull it out! |

Hi there all.
ive got a charging issue with prs 500.. ive just got a prs 500 , used, a few weeks ago and all well until i tried to charge it in the mains. i plugged the USB lead into an AC adapter (it was for a LG phone ) and plugged it into the wall. if never came on again. it is a used unit, so maybe the battery needs replacing, do you know what to do next? if plugged into a PC via the USB post the device should have power, even if the battery is damaged... is this true? so after testing the USB lead as working, the device has no power when it is directly connected to a PC. could it be the charging circuit that is damaged? also when i flick on the power switch, a little yellow/ orange lamp flashes for a second. thanks..

Just look at the reader after installing stuff, if it says "connected to computer" it's OK to just pull the plug out. If it says anything else. back to the software and hit Reader, changes to "USB connected" , unplug it. Sounds like you have something odd on your PC ? But then anything on a PC is odd to me ......... |

Devices MAY be able to just be disconnected, but the standard is for the Stop or Eject feature. Considering that those who use this feature so not seem to have issues with their Readers, and those who do not do (not an exhaustive study, but sure seems like that) do have some issues, the safe thing to do is to use it. When you have a removeable device there is an icon in the tray that if you click will open to allow you to safely stop (eject) a device. |

I always use the Safely Remove feature on all my USB-connected devices, if it is available. I think only my Sony Walkman doesn't offer this function.
Today, I have charged my 650 via the Blackberry charger for almost 12 hours (I'd waited until I had one bar left on the battery). I am glad to report that my reader has survived this apparently intact, LOL. I will not change the way I use the reader and I will now wait to see how long this charge will last. |

I suggest you leave the unit plugged into the USB port for at least a few hours. Make sure the PC does not go to sleep during this time, or that will drain the battery as well. If it charges OK via USB, I would suggest getting a new wall adapter. |

pidgeon92... don't resurrect the "too much power" story again... it's been killed so many times... USB is 5V at 500mA as standard... the voltage is ALWAYS 5V while the current can vary (I use 2,000 mA USB PSU)... excess voltage fries things, excess current is just that - a device takes as much current as it needs - if it wants 500mA and there's 2,000 available then it takes 500mA.
Modern USB powered devices can also handle variable power and can take from 500mA upwards depending on the device, they start at 300-500mA and then query if more is available, if it is then it'll step the power draw up to the device's max (or the PSU's max if less than the device). Bottom line: Excess voltage can wreck things but USB PSUs are a standard 5V so no excess unless PSU is totally broken. Current is taken as needed...

As long as you do not unplug your device in the middle of writing information to it then there will be no problems. I currently have four USB hard drives, numerous USB flash drives, two Sony readers, an iPhone and an iPod all of which I connect to my PC on a regular basis. The only one of these I 'eject' is the iPod which for some reason does not like just being unplugged. |
