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.
