What do the battery lights mean on my mouse?
Some keyboard and mouse models feature a battery light that shows the current status of the batteries. The following table describes the different lights and states.
Single long green blink
Batteries are good. This occurs when batteries are first installed or every time that the device is turned on.
Slow green blink
Device is docked in the charging station and is charging properly.
Device is docked in the charging station and does not need additional charging.
Presenter Mouse (Japanese version)
Laser pointer is on.
Device is discoverable (trying to connect to the transceiver).
Slow red blink
Batteries are low and need to be replaced.
Slow red blink
Batteries are low and need recharging.
Fast red blink
Device is docked in the charging station, but there is a charging error. Reasons for errors: The wrong type of battery is installed; the battery or batteries are missing; or the battery connection is bad. Solutions: Make sure that the correct battery or batteries are installed, and are installed correctly. If necessary, remove the batteries, wipe them with a clean cloth, and reinsert them.
Presenter Mouse (Standard version)
Laser pointer is on.
Momentus is a SATA drive, so you can put it in any PC that has SATA bus to access the drive.
If you can borrow a SATA to USB dock, you can put it in the dock and plug the dock to USB port on a computer to get your data out the drive.
One example for the USB dock is EZ-dock and you can search on Internet for the picture.
Your circuit board could be bad, but i would pull out the circuit board and spray contact cleaner onto the button, let it dry a few minutes and connect the battery and press that button quiet a few times and see if that fixes the problem.
I had the same problem with flashing red light on my charging dock (within 10 sec after 2nd green light came on). I did fix it. There is a rust brown securing tab that holds the battery in place. Mine must have a broken spring..... So, I put the battery into my camera, pushed securing tab over the battery and then wedged a toothpick tip to keep battery tab in place. Once back on the charger, I had no more flashing red light. The battery is charging correctly. The problem was that the battery was not held down into place correctly. I now just have to unwedge the toothpick tip to remove the battery...but not really an issue at all as I keep the battery in there all the time. Very easy fix!!!
Others suggested to reseat the plastic dock. But mine was secure. Somewhere there is not a good battery connection that is causing the red flashing light. I am thankful to figure it out. Hope this helps you.
I had the same problem. I needed to take the clear plastic insert off but then I had to put a rubber band around the dock and camera (more on the left of the camera and dock) to hold it evenly on there since the camera was leaning on the right and wasn't charging for me. Now it charges as soon as I put it on there with the rubber band with no blinking red light anymore! Hope this helps!
Verify that BlackBerry Device Software is installed on the computer.
If the BlackBerry smartphone is connected to a laptop computer using a docking station, disconnect the docking station from the laptop computer and connect the BlackBerry smartphone directly to the laptop computer.
If a third-party application uses the same communications port as the BlackBerry Desktop Software, close the third-party application.
If you use a USB adapter to connect the BlackBerry smartphone to a serial port, temporarily connect the BlackBerry smartphone to a USB port.
In the BlackBerry Desktop Manager, double-click Application Loader.
Follow the Application Loader tool prompts to install the BlackBerry Device Software.
Thry this: turn your computer OFF. Gently unplug and replace the data cable connection to the computer several times. Do the same to the drive end of the cable. Leave one end unplugged. Turn on the computer and when the Mac os is set up and waiting for you, plug the drive in and see if the computer recognizes and reads the drive. The problem is usually corrosion on the contacts that prevent proper contact.
Driver could be corrupt. Disconnect the printer or at least be sure it is turned off.
I'd do both and reinstall the CD software program that came with
the printer. When the software program asks you to connect the
printer to the USB port, do so and it should again work properly.
Hope this helps. Bud

I had the same problem where my shuffle just turned off as if it ran out of battery power, and when i tried to plug it in the computer it wouldnt recognise it or i would get an unknow device error. I tried many of the 5r as much as i could but didnt work. Then finally yesterday i tried something new. I pluged the ipod into the computer and left it pluged in to the usb port and i noticed that every time i would lift the ipod from the dock (not all the way) that the light would blink green one time. So what i did was i positioned the ipod back on the dock then lifted it until the green light blinked and i turned it on, and it works now, the battery is charged. However i havent tried to plug it back in the computer to see what happens but i can listen to my music now.
