BA sometimes doesn't charge from USB

[Skwyk]

My BA sometimes doesn't charge from USB sync + charge cable. When I connect it, PDA shows "Charging" and LED flashes, but battery doesn't charge... But sometimes all is OK!
And because my charger is at home, at work i need to charge using my cable :S Can someone explain me, why my phone doesn't charge sometimes? I have tried to make Hard Reset, but the problem still exist... And this situation is not predictable, so I don't know, when my PPC will charge, and when it wont...

I've also tried to use AC -> 5v USB adapter with my cable, problem exists too...
PS. BTW, now my BA charges from USB, but at morning its battery was 0% (all night it was connected to USB cable and showing "Charging...")...

Help please :(

P.P.S. Sorry for my English.

Here is my thoughts - this happened to me

If I connect my USB/sync cable to a PC at home it charges fine, but I also have a laptop with a PCMCIA USB2.0 card and when I connect the XDA to this, it says charging, but is not :!: exactky the symptoms you describe. I have had both batteries completely discharge in this way and everything was wiped out.

I think that my PCMCIA card does not generate enough current to actually charge the battery, but since it is cannected via USB, the phone is foolled into thinking it is charging. I have verified this by connecting to the USB1.1 port on my laptop motherboard & it charges OK

Yes, I also think so, but sometimes it charges! :?
I will try active USB hub, maybe it will help? :roll:

P.S. I also bought AC charger, but when I use it power LED sometimes light RED but not orange :? Is it normal? Battery charges OK.
