I have two computers. If I connect my Nokia to one of them using the usb cable the charge process will start. If I connect the phone to the other computer (using the same cable!) it won't start charging.

Any suggestions what the problem is?

(I couldn't find a usb related difference between both computers)

Some USB ports are able to provide power as well as data transfer, others can be data only. Sometimes some USB ports on one computer will be one way, while other ports on the same computer will be the other way.

Might some USB ports provide less power then others, too? (I think so, but I don't know the facts.) –  Nathaniel Feb 9 '10 at 21:34
    
None of the usb ports of the "problem" computer does work. My MP3 player charges happily on the same ports. –  user4085 Feb 9 '10 at 21:35
    
You're able to charge your MP3 player on the problem pc, but not the Nokia? Perhaps the devices have different power requirements...that's all I've got. –  Grant Palin Feb 9 '10 at 21:52
    
-1 All standard-compliant USB ports must provide power for devices! Device may consume 1 unit load (100mA for USB2.0 and older, 150mA for USB 3.0) without negotiating power consumption. Computer may refuse to provide more than 1 unit load to device. There are USB ports with power-only. They have a resistor between D+ and D- lines, so device know that port won't talk back. Please provide good source on "data only" USB ports if you want to get rig of my down-vote. –  AndrejaKo Jul 24 '10 at 13:51
    
Speaking anecdotally (sp?) I've had USB ports on previous computers that did not provide power. In addition, I've used USB hubs that did not provide power. –  Grant Palin Jul 24 '10 at 19:30

I have experienced that on some laptops:

The phone won't charge while the laptop is only running on battery – but when the power adapter is connected to the laptop, the phone is charging.

Same problem here: My Nokia won't charge, if I connect it to the USB-hub built into my Dell monitor, but my MP3 will.

And Grant Palin is right: It's a power requirement issue. If I connect my Nokia directly to a USB-port on the computer, it charges as it should.

I'm here of course because I've experienced the same issue. I changed computers at work and when I plugged my e-52 into the new PC, no charge.

Let's recap some basics:

  • When you plug your e-52 into a computer for the first time, a pop-up window appears "New Hardware Found. Do You Want to Download Software?" Here I clicked YES. For some unknown reason, my PC couldn't locate the software. Let's not get into why. I think here you need to manually download PC Suite or OVI Suite. I didn't want to at this stage.

  • Another thing is, when you plug e-52 into the PC, the phone gives you a list of MODES that you have to choose one from to continue:

    • PC Suite
    • Mass Storage
    • Image Transfer
    • Connect to Web
  • When I chose PC Suite, my phone wouldn't charge. When I chose Mass Storage, Eureka, it did!

My conclusion is, when you choose the PC Suite mode, the e-52 needs to communicate with the respective software on your PC before in kicks into the charge mode. If your PC doesn't have the appropriate software, the phone won't charge (at least for the first time you plug in your phone).

If that's the problem your having, simply disconnect your phone and plug it back in choosing Mass Storage instead of PC Suite mode. From this point on, every time you plug your e-52 in, it should automatically begin charging.

Same problem here with my Nokia E52. When I plug the phone into a generic USB charger via a micro-USB cable, the phone does not charge. However my bluetooth headset happily charges via the same charger and cable. Also, the phone is only being charged when the laptop is plugged into the power cord, not in battery mode or standby mode, whereas the headset is being charged whenever it is connected to the laptop.

Apparently the phone requires more power than some other devices.

Charging a battery requires much more power than simply operating a keyboard or a mouse, it's normal. –  Gnoupi Aug 4 '10 at 7:50
