When I plug the USB into my laptops (I've tried two) I get a "USB Device Not Recognized" error message. Is it still charging? Screen remains blank.

It doesn't connect to your computer through USB. It will charge that way but you can't connect to the device. Your computer is trying to "read" it like it would a flash drive.

Press the button on the top of the device and it will wake up the screen to show you the charge level. This device can not interface with your PC via USB and will only use it to charge.

I charge mine on the wall socket with a plug-in that accepts USB. Even though it doesn't recognize on your computer, you should see a lightening bolt where the battery is to indicate whether it is charging.

As far as I know the cable is for charging. Section 11 of manual saysPlug your Pulse to computer to charge it, not to synchronise your data. From that I understand it cannot interface it will just use the power from the USB to charge internal battery,sync is carried out through Bluetooth either by it's own regular updates or forced updates by press button on pulse for 3 seconds..Bob

Push the button at the top few times you should have time indication and batterie status.

I'm not a techie in any way, but I have the problem with my computer's front USB port only for my external hard drive (the computer doesn't even recognize something's plugged in). When I plug into the back ports, it works fine. A pain, but it works.

I'm not sure. I've tried 3 different usb cables connected to my laptop and desktop. Nothing happens. No lights blinking like the first 2 or 3 times I charged it. It acts like it's not plugged into anything

I do not own either, but I see no reason why any USB device couldn't be charged using this device. It works on my tablet, phone, e-cigs, and MP3 player. To charge my phone the phone has to be off (otherwise it tries to boot from the USB). That applies to the tablet, as well. If your charging cable ends in an USB it will likely charge. If you have difficulty charging, try turning it off. I've found that it will fully charge my tablet once OR charge all my other devices (2 e-cigs 1300's, phone and MP3 player) once.

Check your charging cable and (if applicable) the USB Wall Jack. I had this issue a while back, where the wall jack connector was not providing constant power (it'd provide it in a pulsing fashion). I later had a bad cable. Once I replaced the bad cable, it started charging with no issues.

Mine died (the USB) and I sent it back for replacement. No problems since. That has been 6 months ago. I think they had some issues that may have been corrected.

Mine have always worked. Make sure the outlet you're plugging into has the correct voltage and that the indicator light is solid. I thought mine wasn't charging once but the outlet (GFCI) had tripped! Sorry I'm not more help.

It has been suggested, and demonstrated to work, by many that you should perform the following steps, which may help you too:1- Remove battery pack from device.2- Insert device into USB port on computer.3- After computer recognizes device, insert battery pack and [safely remove] device.4- Reinsert the device into the USB port with battery pack intact.It should then begin to charge and should respond as usual.Hope that helps!

i was having this issue as well...but i read that there is a RED light that turns on when the battery is charging...so i played with the USB that is plugged into the unit, and found that the red light turns on when its plugged about HALFWAY in. i checked, and it IS in fact charging. try adjusting the B side of the USB (mini part thats in the actual unit) before you return it.

Hello, I made the big mistake by buying this without knowing how it was exactly going to work.After research I managed to put my external gpu together & it did not work on my laptop because I had also no expresscard slot.I never tried USB because I think that the connection is not strong enough. What kind of laptop do you have? It mostly work on ACER laptops.I have ASUS and that's not good for this, Some ACER laptops have an extra slot on the motherboard where you can connect it to and that's what I saw someone doing in a youtube video& it worked.

I had issues with at least two major PC brands whereas depending on the USB port I use USB flash drives, the unit is not recognized by the BIOS/UEFI, or it detects but later can't be open by the install application/boot loader. Sounds silly, but try to use a different USB port and see if that works for you.

I assume you mean it's not recognized Try plugging it into the cord first then the cord into your usbI can't give you an explanation but it work for me on previous machines Also take a flash drive to test that port. Occasionally they do fail
